Pankaj,
In addition to Mark's advice, I would suggest:
1. Log into the target (eg. RRS) RS and turn on the following flag:
trace "on", "dsi", "dsi_buf_dump"
go
2. Log into the RRS and resubmit the transaction. Eg
resume connection to RDS.rdb
go
3. Tail the RDS errorlog and view dataserver error messages related to the resubmission in real time.
Regards,
Jean-Pierre
