I also suggest upgrading the CMOD System log, if you have an older Instance. (maybe before v9.5). You can tell by looking at the System Log AG. The "msg_text" field on older versions is 254 characters. The new one is 2000 var. In the document it is "Optional". If you don't upgraded it, the end of line in the Message is truncated. Also adds DB2 Timestamp columns in addition to CMOD date/timestamps.
https://www.ibm.com/support/pages/upgrade-guide-content-manager-ondemand-server-v1010Optional, but recommended. Update the System Log and System Load application groups and folders to support new style dates.
Important: Once this is performed, older clients (prior to V9.0.0) will not be able to query the System Log or System Load folders.
Note: When the System Log and System Load application groups are updated, the current table will be closed and a new one will be opened once a new message or load is generated.
Note: Running these update commands will remove any user/group specific folder fields that have been defined for the System Log and System Load Folders. Customers will have to add the user/group specific folder fields again after the update is done.
Update the System Log application group and folder:
arssyscr -I instance_name -l -u
Update the System Load application group and folder:
arssyscr -I instance_name -a -u
