You might be able to get it from an audit file.
The command to turn auditing on is omconfaud <service> <audit level>.
So, for example, I often use:
omconfaud sr 11 ld 11 unix 11
This shows me who is sending or receiving an email and when it arrives is their mailbox, stuff like that.
The audit level can go as high as 99, and I'd assume you want to see that for Remote Client Interface (rci). Though I don't know if it would log the entries you're mentioning there, I've never really done logging to find that.
I suspect it will though.
Be aware, that as you turn up the audit level, the load on your server will go up due to increased disk activity. To stop auditing, set the services to an audit level of 0 (this is the dafault, BTW).
