Hi Martin,

This is a new XBSA library that I developed (as per specs) and built on AIX 5.2. We've our own network storage manager and this XBSA library is supposed to facilitate backup and restore of XBSA supported clients. With IDS, we've configured Onbar (XBSA client) to use our XBSA library. Our storage manager remotely triggered Onbar, which in turn loaded our library - the loaded segment is different from IDS shared memory segments..
900000000d96000 38c2b /usr/iTRx/bin/libxbsa.so/

The SHM identifier received from Onbar by XBSA function BSASendData doesn't match with any of the segments known to IDS.(onstat o/p given at the end). But I guess it might be a SHM segment created by Onbar to write backup data because it gives a different identifier each time. I could see from "onstat -u" that three user threads got started for "informix" user after calling Onbar.

Thanks,
Satheesh
