We are backing up our Oracle database via TDPO. What we are attempting to do is duplicate the target database to a new database. This new database will be a test database for our developers.



Our TSM server is on a Windows 2000 machine. Our Oracle database is on an AIX 4.3 system. We execute a script which uses RMAN commands to setup the channels, which then runs the 'duplicate target database to new_database' command. The script runs for a while, but then fails. On the TSM server log, we see the following error message:



11/12/2002 16:10:33 ANR0480W Session 17802 for node TARGET_DB_NAME (TDP Oracle AIX)

terminated - connection with client severed.

11/12/2002 16:10:33 ANR0480W Session 17801 for node TARGET_DB_NAME (TDP Oracle AIX)

terminated - connection with client severed.



The TDPO error log on the AIX system we are restoring to has this message:

11/12/02 16:11:33 sessRecvVerb: Error -50 from call to 'readRtn'.

11/12/02 16:11:33 sessRecvVerb: Error -50 from call to 'readRtn'.



Here is the tail of the rman logfile:



RMAN-08031: released channel: t1

RMAN-08031: released channel: t2

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

ORA-19511: ANS1017E (RC-50) Session rejected: TCP/IP connection failure

RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE.RESTOREBACKUPPIECE



Does anyone have any idea on how to fix this or know what the cause may be? It is obviously some type of TCP/IP communications error.



Thanks!
