A stores application data in a Persistit database. ds-cfg-persistit-backend ds-cfg-pluggable-backend org.opends.server.backends.pluggable.BackendImpl Default this to the db/backend-id Specifies the path to the filesystem directory that is used to hold the Persistit database files containing the data for this backend. The path may be either an absolute path or a path relative to the directory containing the base of the directory server installation. The path may be any valid directory path in which the server has appropriate permissions to read and write files and has sufficient space to hold the database contents. db ds-cfg-db-directory Specifies the permissions that should be applied to the directory containing the server database files. They should be expressed as three-digit octal values, which is the traditional representation for UNIX file permissions. The three digits represent the permissions that are available for the directory's owner, group members, and other users (in that order), and each digit is the octal representation of the read, write, and execute bits. Note that this only impacts permissions on the database directory and not on the files written into that directory. On UNIX systems, the user's umask controls permissions given to the database files. 700 ^7[0-7][0-7]$ MODE Any octal value between 700 and 777 (the owner must always have read, write, and execute permissions on the directory). ds-cfg-db-directory-permissions Specifies the percentage of JVM memory to allocate to the database cache. Specifies the percentage of memory available to the JVM that should be used for caching database contents. Note that this is only used if the value of the db-cache-size property is set to "0 MB". Otherwise, the value of that property is used instead to control the cache size configuration. 50 ds-cfg-db-cache-percent The amount of JVM memory to allocate to the database cache. Specifies the amount of memory that should be used for caching database contents. A value of "0 MB" indicates that the db-cache-percent property should be used instead to specify the cache size. 0 MB ds-cfg-db-cache-size Indicates whether database writes should be primarily written to an internal buffer but not immediately written to disk. Setting the value of this configuration attribute to "true" may improve write performance but could cause the most recent changes to be lost if the directory server or the underlying JVM exits abnormally, or if an OS or hardware failure occurs (a behavior similar to running with transaction durability disabled in the Sun Java System Directory Server). false ds-cfg-db-txn-no-sync Low disk threshold to limit database updates Specifies the "low" free space on the disk. When the available free space on the disk used by this database instance falls below the value specified, protocol updates on this database are permitted only by a user with the BYPASS_LOCKDOWN privilege. 200 megabytes ds-cfg-disk-low-threshold Full disk threshold to limit database updates When the available free space on the disk used by this database instance falls below the value specified, no updates are permitted and the server returns an UNWILLING_TO_PERFORM error. Updates are allowed again as soon as free space rises above the threshold. 100 megabytes ds-cfg-disk-full-threshold
