Subversion Repositories Projects

# This is the configuration file for the Berkeley DB environment

# used by your Subversion repository.

# You must run 'svnadmin recover' whenever you modify this file,

# for your changes to take effect.

### Lock subsystem

#

# Make sure you read the documentation at:

#

#   http://www.oracle.com/technology/documentation/berkeley-db/db/ref/lock/max.html

#

# before tweaking these values.

### Log file subsystem

#

# Make sure you read the documentation at:

#

#   http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/env_set_lg_bsize.html

#   http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/env_set_lg_max.html

#   http://www.oracle.com/technology/documentation/berkeley-db/db/ref/log/limits.html

#

# Increase the size of the in-memory log buffer from the default

# of 32 Kbytes to 256 Kbytes.  Decrease the log file size from

# 10 Mbytes to 1 Mbyte.  This will help reduce the amount of disk

# space required for hot backups.  The size of the log file must be

# at least four times the size of the in-memory log buffer.

#

# Note: Decreasing the in-memory buffer size below 256 Kbytes

# will hurt commit performance. For details, see this post from

# Daniel Berlin <dan@dberlin.org>:

# If you see "log region out of memory" errors, bump lg_regionmax.

# The default cache size in BDB is only 256k. As explained in

# http://svn.haxx.se/dev/archive-2004-12/0369.shtml, this is too

# small for most applications. Bump this number if "db_stat -m"

# shows too many cache misses.

# Disable fsync of log files on transaction commit. Read the

# documentation about DB_TXN_NOSYNC at:

#

#   http://www.oracle.com/technology/documentation/berkeley-db/db/ref/log/config.html

#

# [requires Berkeley DB 4.0]

# set_flags DB_TXN_NOSYNC

#

# Enable automatic removal of unused transaction log files.

# Read the documentation about DB_LOG_AUTOREMOVE at:
