libdb source code

It may also be that an application has created a database file in one transactional environment and then moved it into another transactional environment. If that is not possible, and you have to mix both headers, wrap one of the #include lines as follows. You can use the DB_ENV->memp_trickle method to spread out the I/O that checkpoint will need to perform (the DB_ENV->memp_trickle method ensures a specified percent of the pages in the cache are kept clean). What are the Benefits of Using the Berkeley DB SQL Interface? When a Berkeley DB application calls the database handle close method to discard a database handle, the dirty pages in the cache will written to the backing database file by default. Code: skippy $ equery u sys-libs/db [ Legend : U - final flag setting for installation] . If mining, add the -detachdb flag to ./ppcoin-qt (probably best to just do it anyway). ), page fill factor, and some minimal amount of meta-data overhead. Why is there a lot of disk activity when I exit my application? BerkeleyDB selects the active transaction with the lowest Log Sequence Numbers (LSN) and flushes pages corresponding to that LSN to the disk. Such failure returns will be passed back to the function that originally called a Berkeley DB interface. Sorry for > blaming Tomcat. I thought Berkeley DB was a key/value database, what is the SQL API? However, the different storage architecture (and time available for the release) has meant that there are some caveats about 100% compatibility: No, Berkeley DB does not include a complete copy of SQLite's code, we've taken out the btree files. Also you can consider key/value pairs each as a single row in a table where the columns are data encoded within either the key or the value by the application. Here is what I did for ubuntu 16: Err:15 http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu disco Release, Also commonly fixes : Information about ongoing transition to db5.3 MPools can be evicted only when the data that they are holding is persisted on stable storage. BDB was commercially supported and developed by Sleepycat Software from 1996 to 2006. How can I migrate data from SQLite to Berkeley DB? Unique key constraints are supported. In other words, separate the uses of Berkeley DB and the uses of Microsoft's OLE DB library so that they are not mixed in your code. In other words, this avoids the maintenance of a secondary index, and the associated lookup cost at runtime. I see an ADO.NET package, but do you have a System.Data.SQLite package? Page format on-disk and in memory remains the same to trade off the format conversion overhead. Does Berkeley DB support direct access to cursors via SQL? Linux operating systems including those based on Debian[21] and Fedora[22] ship Berkeley DB 5.3 libraries. NOTE: This was the last release published under the Sleepycat License before Oracle switched it to AGPLv3 [1] starting with version 6. You can not wrap db_cxx.h using this technique. BerkeleyDB also provides "recno" indexes that are built on top of B+Trees for ordering and storing data sequentially. rev2023.4.17.43393. Sci-fi episode where children were actually adults. It might take days or weeks. The Berkeley DB data part of these records is always empty: SQLite only ever sets or uses the keys. Using DB_CONFIG to set DB_MULTIVERSION and DB_TXN_SNAPSHOT will not work correctly in any version of the SQL API. Here is an example of a typical build command: clang++ -std=c++1y -stdlib=libc++ -fexceptions -I/usr/local/include -c -O2 -Wall -ferror-limit=5 -g -O0 -ftrapv lib/format.cpp -o format.o The earlier -O2 is there because that's the default I'm using, but I believe the later -O0 overrides it, right? Berkeley DB is a family of embedded key-value database libraries providing scalable high-performance data management services to applications. Berkeley DB HA supports online upgrades from one version to the next by maintaining the ability to read and apply the prior release's log records. $ ../dist/configure --enable-cxx Are there any constraints about number of tables? Automated Vulnerability Detection in Source Code Using Deep Representation Learning. That will allow you to access your data members or methods. Yes, Berkeley DB automatically runs each command in its own transaction, and if the command does not fail, its changes are automatically committed. It's caused by a fix in the ext4 fsync code with That encoding includes length information, so it effectively duplicates the length that Berkeley DB maintains for each key/data pair. Usually, what appears to be a corrupted database, is usually the result of two database handles not sharing an underlying database environment. Run yum provides '*/libdb-4.7.so' and it will tell you what provides that file so then you know what to install. In addition to the in addition to the SQLite-specific compile-time flags Berkeley DB's SQL API can be further tailored with the following: There are no differences between the Berkeley DB's SQL API and the SQLite API related to SQL data types. Given a binary, such as a firmware image, it attempts to detect. Yes, the built-in .dump command will produce SQL that can be executed to recreate a database. This article suggests replacements for libdb in RHEL. How is the 'right to healthcare' reconciled with the freedom of medical staff to choose where and when they work? When all of the memory available in the database environment for transactions is in use, calls to being a transaction will fail until some active transactions complete. $ cd db-4.8.30.NC/build_unix/ As is common with SQLite, there is 3rd Party support for PL/SQL which may be a viable alternative for your application. [8][9] Previously, Berkeley DB was redistributed under the 4-clause BSD license (before version 2.0), and the Sleepycat Public License, which is an OSI-approved open-source license as well as an FSF-approved free software license. Here is the extract from R12 Doc ID 761564.1 OS Library Patch for Oracle HTTP Server (on Oracle Linux 5 and RHEL 5 only) Download and apply the patch 6078836 from My Oracle Support to fix an issue with the Oracle HTTP Server (missing libdb.so.2) bundled with the E-Business Suite technology stack. Yes, this is supported by sqliteodbc using sqlite3_interrupt. http://download.oracle.com/docs/cd/E17076_02/html/index.html Presently Oracle presently develops and maintains releases and permits free and open source usage bounded by the GNU AGPL license terms. The Visual Studio 2008 project files will by default build for Windows Mobile 6.5.3 Professional. The 2.x releases added a locking system enabling concurrent access to data. Yes, conditional statements are fully supported. > > > > So I guess there is something wrong with Tomcat here. BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. It has support for variable-length keys and values for BTree and Hash index access methods. You will need to migrate the schema and data using the sqlite3 command line interface to .dump and then the Berkeley DB dbsql command line to .load the data and schema from the dump file. Does Chain Lightning deal damage to its original target first? Once complete, you should then have a library called libdb_sql-5.0.la and a command line tool called dbsql that can . When a 256KB CSV is stored into an Berkeley DB table, how much space . The simplicity arises from the fact that it is a basic key-value store and not a full-fledged database system that provides querying and schema constraints. In English, you'll be able to smartly and easily catalog your movies, books, magazines, comics, etc. You can, of course, serialize access to the databases outside of Berkeley DB, but that would imply a pretty significant hit to the overall performance of the system. (ppa:bitcoin/bitcoin). Yes - there is an ADO.NET package for Berkeley DB. BerkleyDB uses two-phase locking to permit multiple reader cursors or a single writer cursor to access the database. It is also possible to use the SQLite command line SQL Interpreter to create tables, the command line can be used from a script. By default, log files are automatically removed when all the information they contain has been synced to the database file. FULL is the default setting, if no pragma is used. Hash indexes use linear hashing to balance the keys across buckets. Note that the blockchain size is dynamically increasing. A soldier wakes up in someone else's body and discovers he's part of an experimental government program to find the bomber of a commuter train within 8 minutes. Remember to build with --enable-sql passed to the configure script to generate the SQL library and command line tool dbsql. http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/overview/index.html, C++, Clojure, D, Delphi, Eiffel, Erlang, Go, Haskell, Java, JavaScript, Lisp, Lua, Matlab, Ocaml, Perl, PHP, PL/SQL, Prolog, Python, R, Rebol, Ruby, Scala, Smalltalk, Tcl, Visual Basic, AIX, Android, BSD, DOS, HP-UX, iOS, Linux, OS X, Solaris, VxWorks, Windows, z/OS, https://en.wikipedia.org/wiki/Berkeley_DB, Copyright 2023 If. You are strongly advised to pay close attention to any export/import and/or use laws which apply to you when you import a release of Berkeley DB including cryptography to your country or re-distribute source code from it in any way. The comprehensive feature along with the licensing terms have led to its use in a multitude of free and open-source software. Ive been trying to run cheops and etherape but they prompt me to get libdb.so.3. * Get answers faster with real-time collaboration, version history, searchable shared ScaleGrid is a fully managed Database-as-a-Service (DBaaS) platform that helps youautomate your time-consuming database administration tasks both in the cloud and on-premises. Prefix compression is not used in B+Trees. When using the C API, the DB and DB_ENV handles each contain an app_private field intended to be used to reference application-specific information. SQLite refers to tables with an ID number (in SQLite that's the root page of the btree for that table), whereas Berkeley DB refers to subdatabases by name. This library provides IP defragmentation, TCP reassembly and port scan detection. Our experimental results show that LibDB is more accurate and efficient than state-of-the-art tools on the binary TPL detection task and the version identification task. Again, this is just the initial version, I prabably will change it very soon. [1] https://oss.oracle.com/pipermail/bdb/2013-June/000056.html Berkeley DB configures a default page size based on the underlying file systems block size. Bloomberg LP continues to develop a fork of the 2013 version of BDB within their Comdb2 database, under the original Sleepycat permissive license. Is there anything special about temporary databases beyond the fact , Can the users not specify primary key when create a table in Berkeley , How can I know how many tables are there in a Berkeley DB 11gR2 . Berkeley DB will use more than 256KiB because there is some overhead in indexing the keys + some bytes of per page overhead. Try specifying the, Finally, reducing the isolation level can significantly reduce the number of deadlocks seen by the application. Download Free PDF View PDF. [12], Berkeley DB has an architecture notably simpler than relational database management systems. Security Advisories from late '97 and early '98 [undated] xfree insecure socket creation [undated] xfree insecure /tmp files [undated] xfree insecure file handling Source Code: Directed by Duncan Jones. The OS variable is usefull here, so it will work on both Win/Linux systems: One special case is worth mentioning: applications that want an integer primary key for a table should declare the table as: create table t(id integer primary key, ). Foreign key constraints are currently not supported (the statements will be parsed, but not enforced). The index overhead is dependent on the size of the key, so difficult to estimate. Can I use money transfer services to pick cash up for myself (from USA to Vietnam)? The virtual machine acts as the bridge between sqlite and the storage layer (in this case, BerkeleyDB) and has the logic to translate virtual machine code to storage level calls. What are the key benefits of Berkeley DB storage engine? Use synonyms for the keyword you typed, for example, try "application" instead of "software.". See the Remote filesystems section of the Berkeley DB Reference Guide for more information. libdb.a (libdb-5.3.so) is needed by perl-1:5.30.3-2.ppc We had the latest version of db 6.2.38-2 installed on our systems and now we have to downgrade to db-5.3.28-1 which was recently uploaded to the AIX toolbox. This is not a bug of BDB. The programming interface (API) and SQL language supported are identical: Berkeley DB uses that part of SQLite without any changes. Berkeley DB wasn't designed to use raw disk partitions, for a few different reasons: All that said, the one strong argument for porting to a raw partition is to avoid double buffering (where a copy of a Berkeley DB database page is held in both the DB cache and the operating system's buffer cache). analysis. In Berkeley DB, databases can always be recovered to a consistent state, because write-ahead logging semantics are always enforced on the Berkeley DB log. Any time you are sharing a handle across multiple threads, you must specify DB_THREAD when you open that handle. (I should mention that DB database applications are able to continue running when there is no disk space available, unlike many database products -- because other applications can run DB applications out of disk space, it was necessary to make DB resilient to a lack of disk space.). The return values for all Berkeley DB functions are grouped into the following three categories: All values returned by Berkeley DB functions are less than 0 in order to avoid conflict with possible values of errno. Is it possible to return error codes when the data itself is corrupted? Lets bypass the bug by running the following command: It basically opens the dbinc/atomic.h file and changes all the __atomic_compare_exchange appearances to __atomic_compare_exchange_db. Yes. This API has been implemented in most common programming languages. It is common This is handled by the SQLite parser, making the id an alias for the row ID. Berkeley DB does optionally include strong cryptographic support. The programming involved to establish a JDBC connection is fairly simple. 5.1 is known to work, buts databases are incompatible with official builds created with db-4.8.". Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. other options as snap may be considered if the error message is a concern. LibDB. Berkeley DB doesn't have any built-in support for databases where the data values will all be zero length: it stores ~8 bytes per index record to indicate a zero-length data item, where SQLite has a table type specially for this purpose. Code which is needed for any EBCDIC based machine. The most costly queries are ones that involve many random lookups, since each individual lookup acquires page locks in Berkeley DB. If a system were to write a database page back to the remote filesystem at the same time as another system read a page, a core dump in the reader could result. RHEL 8 and RHEL 9 currently provide libdb 5.3.28, which is di. Their work is not available in any form, but serves as a proof point. BerkeleyDB is a simple KeyValue store. If this is a case then you need to install libdb-4.8 from the source code. Well, it compiles with libdb++-dev and sudo apt-get install libminiupnpc-dev -y thanks to this guy. The Berkeley DB includes B+tree, Extended Linear Hashing, Fixed and Variable-length record access methods, transactions, locking, logging, shared . The project was started circa 1988 and is more than 30 years old. These keywords apply to update transactions, and fully understanding them requires understanding SQLite locking. After 3 hours googling I almost gave up then this one worked for me! Log files contain information about transactions, when you see this message it is likely that the application or some other process or systems anomoly may have removed some or all of the log files without properly resetting the database log sequence numbers (LSNs). SQLite implements the VACUUM command as a database dump followed by a complete reload from that dump. Building the C# API produces a managed assembly libdb_dotnetVERSION.dll , containing the API, and two native libraries: libdb_csharpVERSION.dll and libdbVERSION.dll . The open source license has changed from the (proprietary) Sleepycat license to the (industry standard) AGPL. Berkeley DB uses the SQLite encoding of values directly, with the exception of a custom encoding for row IDs. How do I configure Berkeley DB to build the SQLite compatible API and , Which operating systems and platforms are supported by the Berkeley DB . Yes, supported by sqliteodbc using sqlite3_interrupt. Automatic deadlock detection is enabled, it uses the default deadlock resolution algorithm. BerkeleyDB is primarily a key-value store. That is, they are not required to avoid deadlock (nor do they prevent deadlocks, but such deadlocks are automatically detected by Berkeley DB). What are the constraints for each Data Type? Upon reopening the database, the site synchronizes with the rest of the replication group. That will produce a binary called dbsql.exe in the directory Win32/{Debug|Release}/. As of release 5.1 of Berkeley DB, the VACUUM command will compact and compress the database file(s). Yes, SQLite has support for prepared statements via the C/C++ API. The exact warning message is: "Security warning for System.Data.SQLite.2008". You must install BerkleyDB version 4.8 for everything to work. For 7x24x365 (five-nines) operation this is critical. This implies that every possible hardware resource is shared. A return value of 0 indicates the operation was successful. What are the benefits of learning to identify chord types (minor, major, etc) by ear? See the db_create and db_env_create documentation for more information. The maximum length of a string or blob field is 1 billion bytes. Currently, there is no support for pre-empting a low-priority operation. MOC (music on console) is a console audio player with a simple ncurses interface in playmp3list style. I am trying to test a mod that I've created of Peercoin. Beginning in 5.2, BEGIN EXCLUSIVE will create a transaction that will block new transactions from starting, and block existing transaction from making forward progress, until the exclusive transaction is committed or aborted. $ make See the Run-time error information section of the Berkeley DB Reference Guide for more information. Data is stored as raw-bytes. The BDB version of compact won't adversly impact ongoing database operations whereas SQLite's approach does. This is what is known as "Concurrent Data Store" (CDS). You have a number of options to consider when setting up Berkeley DB's source code for a build. If you upgraded your Ubuntu to 20.04 or higher and tried to run the above commands you may get an error, because Bitcoin PPA has not released libdb-4.8 for Focal Fossa (Ubuntu 20.04) yet. SQL used to access statically typed databases will be compatible with Berkeley DB. Code Gregory Burd merge 5.3.21 5b7b02a on Nov 14, 2012 7 commits Failed to load latest commit information. We are pleased to announce a new release of Berkeley DB 11gR2 (11.2.5.3.21). The sqlite3_prepare() and sqlite3_prepare_v2() interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2() use UTF-16. Connect and share knowledge within a single location that is structured and easy to search. The name "Berkeley DB" is used by Oracle Corporation for three different products, only one of which is BDB:[14]. What tuning tools are available for use with Berkeley DB? Before using a DBT, you must initialize all its elements to 0 and then set the ones you are using explicitly. You may need to set flush_mmap_pages to zero to see the behavior that you saw in RHEL 4. How can I make inferences about individuals from aggregated data? If you need to rebuild the libdb.a, you need to merge the debug.c using the debug.c.orig as the base to your debug.c. Berkeley DB (BDB) is an unmaintained embedded database software library for key/value data, historically significant in open source software. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Finding valid license for project utilizing AGPL 3.0 libraries. Multi-version Concurrency Control (MVCC) Internally, SQLite has the notion of read-only vs update transactions. Linux debugging, tracing, profiling & perf. Berkeley DB is engineered to use as few operating system calls as possible, this makes it is highly portable. This is possible due to the multiple reader-single writer model and two phase locking. Can Berkeley DB use NFS, SAN, or other remote/shared/network . Berkeley DB (BDB) is an unmaintained embedded database software library for key/value data, historically significant in open source software.Berkeley DB is written in C with API bindings for many other programming languages.BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. Either it works, or it fails and you have to try again sometime. Use the following command to verify the status of the blockchain synchronization: sudo add-apt-repository ppa:bitcoin/bitcoin, sed -i 's/__atomic_compare_exchange/__atomic_compare_exchange_db/g' dbinc/atomic.h, sudo apt-get install libboost-all-dev libzmq3-dev libminiupnpc-dev, http://download.oracle.com/berkeley-db/db-4.8.30.zip. Alternatively, you can limit the number of sequential write operations scheduled by the DB library, using the DB_ENV->memp_set_max_write method. For example, if machine A opens a database environment on a remote filesystem, and machine B does the same, then machine A acquires a mutex backed in that remote filesystem, the mutex won't correctly serialize machine B. Why has this changed happened and why does the db-6.2.38-2 not fulfill the rquirement (not containing libdb-5.3.so)? There are a few Berkeley DB interfaces where it is possible for an application function to be called by a Berkeley DB function and subsequently fail with an application-specific return. http://forums.oracle.com/forums/forum.jspa?forumID=271, Questions about Berkeley DB's Replication and High Availability (HA) features: For example, if the keys are small, then the index overhead will be small. Berkeley DB returned error number 12 or 22. BDB was once very widespread, but usage dropped steeply from 2013 (see licensing section). So there is no defined order amongst NULL VARCHAR fields. Berkeley DB provides a collection of well-proven building-block technologies that can be configured to address any application need from the hand-held device to the datacenter, from a local storage solution to a world-wide distributed one, from kilobytes to petabytes. Also you need to change the "makefile" to include the "helper_tcpip.c". The Berkeley DB includes B+tree, Extended Linear Hashing, Fixed and Variable-length record access methods, transactions, locking, logging, shared memory caching, and database recovery. BerkeleyDB (sometimes referred to as simply "BDB") is an embedded open-source, database storage library. LibDB is a library and asset management system inspired by the Functional Requirements for Bibliographic Record, RDF triples, and end-usability. Developers, analysts, and DBAs use it to elevate their SQL experience with modern tools to visualize and manage their databases, schemas, objects, and table data, and to auto-generate, write and optimize queries. However, "Upstream Bitcoin considers db-4.8 to be the only supported version. This is a bug in the Windows OS, and not in BDB. What is the story about thread safety -- can a sqlite3 db handle be . MVCC leads to the creation of multiple working sets and tend to grow larger than the cache size. Thanks for helping keep SourceForge clean. Assets 3 Aug 5, 2020 gburd v5.3.21 5b7b02a Compare Berkeley DB 11gR2 (11.2.5.3.21) Berkeley DB 11gR2 (11.2.5.3.21) the one used for building the target binary ( /buildbot/path in the example above). What causes an unable to initialize mutex: Function not implemented error? flags Berkeley DB's SQL API can be further tailored with the following: http://www.sqlite.org/datatype3.html">page, http://download.oracle.com/docs/cd/E17076_02/html/api_reference/C/envset_lk_detect.html. $ make install, Tell your system where to find db4.8 Disk space: 400GB accessible at a minimum read/write speed of 100 MB/s. libqt5gamepad5-dev not available in 18.04 repos? This company was acquired by Oracle Corporation in February 2006. The most common reason for this error in a Berkeley DB application is that a system call underlying a mutex configured by Berkeley DB is not available on the system, thus, the return of ENOSYS, (which is the system error associated with the Function not implemented message). Use tracing and profiling functions(sqlite3_trace() and sqlite3_profile()). Download usage is around 20 gigabytes a month, plus around an additional 340 gigabytes the first time you start your node. Exclusive for LQ members, get up to 45% off per month. Full search, partial match (LIKE, GLOB), and custom regular expressions are supported on all column types. The table size is generally limited by the maximum file size possible on the file system. What happens when I turn off replication? The errno value returned by the system is returned by the function; for example, when a Berkeley DB function is unable to allocate memory, the return value from the function will be, A return value that is less than 0 indicates a condition that was not a system failure, but was not an unqualified success, either. libdb_cxx headers missing Ubuntu Third party support for PL/SQL is available. The DB_AUTO_COMMIT flag does not apply to cursors. Source=libdb_dotnet51 TypeName=SWIGStringHelper StackTrace: bei BerkeleyDB.Internal.libdb_csharpPINVOKE.SWIGStringHelper..ctor() bei BerkeleyDB.Internal.libdb_csharpPINVOKE..cctor() InnerException: System.BadImageFormatException Message=Es wurde versucht, eine Datei mit einem falschen Format zu laden. The mapping is simply: The IDs are allocated so that tables ordinary tables always get an odd number and indices get an even number. tar -zxvf db-1.85.4-src.tar.gz Go to the PORT/linux directory cd db.1.85.4/PORT/linux Use the Makefiles to start the compilation. Locking has a significant impact on some queries: we have seen up to 30% of the runtime for some queries connected with locking (and latching). Log files should never be removed unless explicitly authorized by the db_archive utility or the DB_ENV->log_archive method. Can Berkeley DB open SQLite database files or automatically migrate them? Topic: compiling altcoins: libdb4.8 vs libdb5.1 (Read 890 times) "There should not be any signed int. Long-press on the ad, choose "Copy Link", then paste here The Berkeley DB environment should be configured to support more active transactions. libdb_java46d.dll # can be in java.library.path or PATH libdbxml_java24d.dll # ditto libdb46d.dll # must reside in a PATH directory libdbxml24d.dll # ditto xerces-c_2_8D.dll # ditto xqilla21d.dll # ditto The Java bridge DLLs (or whatever they're called) can be moved to a directory only contained in java.library.path, but not in PATH. A program accessing the database is free to decide how the data is to be stored in a record. http://www.oracle.com/us/products/database/berkeley-db/index.html Their byte patterns on a little-endian system are: If you treat them as strings, then they sort badly: On a big-endian system, their byte patterns are: and so, even when compared as strings the keys will sort nicely. You have to write a layer that looks a lot like a file system, significantly increasing Berkeley DB's footprint, and that code will require continuous porting and performance tuning. Due to these properties, many applications like filesystems, LDAP servers and database systems (like MySQL) use BerkeleyDB for their backend storage requirements. The synchronous=ON level in Berkeley DB is equivalent to the DB_TXN_WRITENOSYNC flag and implies that transactions committed before a system crash (such as a hard reboot or power loss) may be rolled back on recovery. BerkeleyDB uses Sqlite to provide an API to execute SQL queries and Sqlite uses the Tuple-at-a-Time query execution model. $ ln -s /usr/local/BerkeleyDB.4.8/lib/libdb-4.8.so /usr/lib/libdb-4.8.so. There is no authentication in SQLite (see Q/A above), in this answer we're using the term user to mean thread or process. Logs are forcibly persisted to the disk as soon as they are generated. Over time, the available memory can be exhausted, and the system can run painfully slow. See data types and language expression documentation on the SQLite site. This is called the "High Availability" (HA) feature set. When MVCC is used, snapshot-level isolation guarantees are provided. http://www.oracle.com/us/products/database/berkeley-db/index.html, http://www.oracle.com/technetwork/database/berkeleydb/overview/index.html, http://www.oracle.com/technetwork/database/berkeleydb/overview/index-085366.html, http://download.oracle.com/otndocs/products/berkeleydb/html/changelog_5_3.html, http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html, http://download.oracle.com/otn/berkeley-db/db-5.3.21.tar.gz, http://download.oracle.com/otn/berkeley-db/db-5.3.21.zip, http://download.oracle.com/otn/berkeley-db/db-5.3.21.msi, http://download.oracle.com/otn/berkeley-db/db-5.3.21.NC.tar.gz, http://download.oracle.com/otn/berkeley-db/db-5.3.21.NC.zip, http://download.oracle.com/docs/cd/E17076_02/html/index.html, http://www.oracle.com/technetwork/database/berkeleydb/db-faq-095848.html, http://forums.oracle.com/forums/forum.jspa?forumID=271, http://forums.oracle.com/forums/forum.jspa?forumID=272, https://oss.oracle.com/pipermail/bdb/2013-June/000056.html, https://oss.oracle.com/pipermail/bdb/2012-May/000051.html. sunrise strain fig farms, To its original target first catalog your movies, books, magazines, comics etc...
