# Berkeley DB-5.3.28

## Introduction to Berkeley DB

The Berkeley DB package contains programs and utilities used by many other applications for database related functions.

This package is known to build and work properly using an LFS-8.4 platform.

## Installation of Berkeley DB

First apply a fix so that this will compile with current versions of g++:

    sed -i 's/\(__atomic_compare_exchange\)/\1_db/' src/dbinc/atomic.h

Install Berkeley DB by running the following commands:

    cd build_unix                        &&
    ../dist/configure --prefix=/usr      \
                      --enable-compat185 \
                      --enable-dbm       \
                      --disable-static   \
                      --enable-cxx       &&
    make

Now, as the `root` user:

    make docdir=/usr/share/doc/db-5.3.28 install &&

    chown -v -R root:root                        \
          /usr/bin/db_*                          \
          /usr/include/db{,_185,_cxx}.h          \
          /usr/lib/libdb*.{so,la}                \
          /usr/share/doc/db-5.3.28

## Command Explanations

cd build_unix && ../dist/configure --prefix=/usr...: This replaces the normal ./configure command, as Berkeley DB comes with various build directories for different platforms.

`--enable-compat185`: This switch enables building the DB-1.85 compatibility API.

`--enable-cxx`: This switch enables building C++ API libraries.

`--enable-dbm`: Enables legacy interface support needed by some older packages.

make docdir=/usr/share/doc/db-5.3.28 install: This installs the documentation in the standard location instead of `/usr/docs`.

chown -v -R root:root ...:This command changes the ownership of various installed files from the uid:gid of the builder to root:root.

`--enable-tcl --with-tcl=/usr/lib`: Enables Tcl support in DB and creates the `libdb_tcl` libraries.

`--enable-java`: Enables Java support in DB and creates the `libdb_java` libraries. Support is currently broken with Java-9.x.

### Short Descriptions

db_archive | prints the pathnames of log files that are no longer in use.
db_checkpoint | is a daemon process used to monitor and checkpoint database logs.
db_deadlock | is used to abort lock requests when deadlocks are detected.
db_dump | converts database files to a flat file format readable by db_load.
db_hotbackup | creates "hot backup" or "hot failover" snapshots of Berkeley DB databases.
db_load | is used to create database files from flat files created with db_dump.
db_log_verify | verifies the log files of a database.
db_printlog | converts database log files to human readable text.
db_recover | is used to restore a database to a consistent state after a failure.
db_replicate | is a daemon process that provides replication/HA services on a transactional environment.
db_stat | displays database environment statistics.
db_tuner | analyzes the data in a btree database, and suggests a page size that is likely to deliver optimal operation.
db_upgrade | is used to upgrade database files to a newer version of Berkeley DB.
db_verify | is used to run consistency checks on database files.
