(Oracle and UDB only) Enables or disables the removal of Oracle archived redo log files or UDB archived transaction logs from the path specified by pdb_archive_path.
true – Allows the removal of archived Oracle redo log and UDB archived transaction log files from the path specified by pdb_archive_path. Removal occurs based on the execution of command pdb_truncate_xlog, or the timing of automatic truncation based on parameters truncation_type and truncation_interval.
false – Disables the removal of archived Oracle redo log files or UDB archived transaction log files.
For Oracle, set this configuration to true when the path specified by pdb_archive_path is established solely for Replication support, and automatic removal of unneeded archived log files is desired.
For UDB, set this configuration to true when UDB is configured to archive logs by setting LOGARCHMETH1 configuration parameter to DISK:<path>, and the automatic removal of archived log files is desired.
If the path specified by pdb_archive_path is shared by other processes, or the removal of archived log files is expected to be performed by processes other than Replication Agent, this parameter should be false.
Configuration parameters truncation_type and truncation_interval, and command pdb_truncate_xlog have no impact when this configuration parameter is set to false.
