Possible physical log overflow during fast recovery

During fast recovery, the physical log can overflow. If this occurs, the database server tries to extend the physical log space to a disk file named plog_extend.servernum. The default location of this file is $ONEDB_HOME/tmp.

Use the ONCONFIG parameter PLOG_OVERFLOW_PATH to define the location for creating this file.

The database server removes the plog_extend.servernum file when the first checkpoint is performed during a fast recovery.
