Problems with RedHat AS3.0 and Oracle 9i

[npatel]

Hi,

We have Oracle 9i database on RedHat AS 3.0 server. While trying to perform Oracle backup using RMAN, following error occurs.



RMAN> run

{

allocate channel t1 device type 'sbt_tape' parms

'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin/tdpo.opt)';



backup tablespace backup_test;

release channel t1;

}

2> 3> 4> 5> 6> 7> 8>

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

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

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

RMAN-03009: failure of allocate command on t1 channel at 05/09/2005 13:20:44

ORA-19554: error allocating device, device type: SBT_TAPE, device name:

ORA-27000: skgfqsbi: failed to initialize storage subsystem (SBT) layer

Linux Error: 104: Connection reset by peer

Additional information: 7011

ORA-19511: Error received from media manager layer, error text:

SBT error = 7011, errno = 104, sbtopen: system error



I also tried sbttest and I got following error.

[oracle@brwsrac3 udump]$ sbttest a -libname /opt/oracle/product/9.2.0/lib/libobk.so

The sbt function pointers are loaded from /opt/oracle/product/9.2.0/lib/libobk.so library.

Return code -1 from sbtinit, bsercoer = 7011, bsercerrno = 104

sbtopen: System error - eg. malloc, fork errors



Following is the contents of error log.

[oracle@brwsrac3 udump]$ tail tdpoerror.log

05/09/2005:13:41:11 TID<27206> ==> ANU0003S An internal processing error has occurred



Could somebody advise to resolve this problem?

Thanks,

Nilesh

Hi -



I don't have this setup as you do for Red Hat - but usually Oracle requires a relink of the library you have referenced.



What is libobk.so linked to??? If it is not linked properly you can see media mgmt errors similar to this on any *nix OS.

Thanks Chris..



For Oracle 9i, media mgmt. libraries are dynamically linked. So, it is necessary to only create soft link in your $ORACLE_HOME/lib to point to libobk.so. I have looked on google as welll as oracle's support site, but I could not find any solution.



Anybody else has suggestions??

Thanks,

Nilesh

I would definitely verify then that you have the right version. 32 vs 64 bit libraries can produce different results... Sometimes playing around with changing out the lib can help.



I am fairly certain this would have to do with the mentioned lib... As I have seen this issue over and over when doing installs on Solaris, AIX and HP. The sbbtest you did only confirms this to me...



But maybe someone else with this specific setup can give you the exact info...

Good luck.
