Hi Angela,
The REORG is the correct course of action, but I noticed that our REORG article was ambiguous about which options to use to resolve these errors. This has now been updated to specifically call out the option to REORG into a new database.
After selecting the option to REORG into a new database, the key value will be the Estimated number of Job IDs. This will need to be a larger number than what your current history database has. If you aren’t certain what your current Job ID limit is, a List History report will provide this information. This article has also been updated with instructions and a screenshot example of what to look for to increase Job IDs.
