RE: RMAN duplicate is failing : database session for channel <channel_name> terminated unexpectedly
Date: Mon, 19 Mar 2012 23:02:32 -0500
I noticed that it generates the following error in alert log: Errors in file /phx11dbt1/u01/app/oracle/admin/vtwdmas/udump/vtwdmas_ora_6462.trc: ORA-07445: exception encountered: core dump [VxBSAGetData()+716] [SIGSEGV] [Address not mapped to object] [0x000000DF8]  
The tracefile has the following message but the sbtio.log doesn't have any information as the size of sbtio.log is 0. SKGFQ OSD: Error in function sbtread2 on line 1156 SKGFQ OSD: Look for SBT Trace messages in file /phx11dbt1/u01/app/oracle/admin/vtwdmas/udump/sbtio.log Exception signal: 11 (SIGSEGV), code: 1 (Address not mapped to object), addr: 0xdf8, PC: [0xffffffff7d736d94, VxBSAGetData()+716]
Couldn't locate any note in Metalink related to this error. Any suggestions will be appreciated.

Have you checked the alert log for the database you are trying to duplicate to?
Oracle has a couple of bug reports for unexpected channel terminations but you'll need the error from the alert log file to narrow it down.

I am trying to duplicate a 3TB database, which has 927 datafiles. It is failing with the following error. Some of the google notes refers me to work with the backup media vendor. I have contacted Netbackup vendor Symantec but has not got a solution yet and wondering if anyone from this list experienced similar problem and have some recommendations.
Database version: 10.2.0.4
Netbackup client for Oracle: NetBackup-Solaris10 6.5.5 OS: Sun Solaris 10.
Channel aux4: reading from backup piece /incr0_TWDMAS_365890_776372926_a2n4d0lu
RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of Duplicate Db command at 03/19/2012 09:50:58RMAN-03015: error occurred in stored script Memory Script RMAN-10038: database session for channel aux1 terminated unexpectedly
BTW: I am able to duplicate many other databases (all smaller than this problematic one) to the same UNIX server without any problem. Not sure if the size or the high number datafiles in backup is causing any issue or not.
