Wed 06 Oct, 2021 - 11:19:25 - OnLineBackup (name - OnLineBackup): The running of the post_olb_script failed after a successful On-line backup. The processd error is 0, the script error is 127. (event [0x00010962])

Environment

Release : 21.2.x

Component : SpectroSERVER

Cause

The post_olb_script being executed from the custom folder was still trying to execute ddm_save. The ddm_save was renamed
   to ddm_save_legacy in favor of a new perl script ddm_save.pl

The post_olb_script was not updated due to it being located in the custom folder to preserve its configuration

Resolution

Update the post_olb_script in the custom folder $SPECROOT/custom/CsScript/ to use ddm_save.pl


Change (or comment out):

    ./ddm_backup $backup_dir/db_$time_string.DDMDb > $backup_dir/ddm_backup.log

To:
    
    ./ddm_save.pl -f $backup_dir/db_$time_string.DDMDb > $backup_dir/ddm_backup.log 2>&1

 

 

Note: The ddm_save.pl script requires the event table to use the InnoDB MySQL engine and will not work if the
             table is using MyISAM. The $SPECROOT/SS/DDM/scripts/convert_current_myisam_to_innodb.pl script
             can be used to convert the DDM events table to InnoDB.
