Re: JadeAuditAccess - How can I retrieve Array Attributes from the Journals

I'll have a crack at it. In JADE 2018 the ability to identify OIDs added to or removed from a collection block update record was added.

Re: JadeAuditAccess.getUserData(pUserName, pIndex); How is pIndex used?

The information is for you to maintain association structures relating transactions to users. The index is the database user table index for the user with that name. You get the index and user name from the sign on, sign off, and change user records, and you get the index from begin transaction, com...

It was found that process termination could take an awfully long time when database caches were very large in a 64 bit database server. Traversing the buffer pool and verifying the state of the buffers didn't cost much but cleanup, that is removing each buffer from control structures (list managemen...
