Dell Avamar for Oracle 19.10 User Guide

An RMAN script that backs up Oracle fails with ORA-19511. RMAN writes output similar to the following to the log file:

RMAN-00571: ===================================================
RMAN-00569: =========== ERROR MESSAGE STACK FOLLOWS ===========
RMAN-00571: ===================================================
RMAN-03009: failure of backup command on ORA_SBT_TAPE_1 channel
at 2014-9-4 16:02:37
ORA-19506: failed to create sequential file,
name="06jtv7ks_1_1", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
sbtbackup: avtar exited, trying to create 06jtv7ks_1_1

The following problems might cause the RMAN backup script to fail with the ORA-19511 error:

• The /var/avamar directory does not have correct permissions to start a backup.

  Use the /var/avamar/clientlogs directory instead of the /var/avamar directory.
  

• Either RMAN or libobk cannot locate avtar.

  The allocate channel command in the RMAN backup or restore script must include Avamar-home/bin as the
  PATH variable or include bindir="/usr/local/avamar/bin".

• An Oracle instance is running as a nonstandard user or group.

  To determine if Oracle is installed as a nonstandard user or group, check the file permissions for the Oracle home directory. For example, use the following commands:
    

  cd /home/oracle/oracle/product/10.2.0/db_1/oradata
  ls -l

  The following output appears in the command shell:

  total 28
  drwxr-x--- 2 oracle oinstall 4096 Aug 26 2014 cataloged
  drwxr-x--- 2 oracle oinstall 4096 Mar 9 18:05 db2
  drwxr-xr-x 2 oracle oinstall 4096 Mar 30 17:21 orcl
  drwxr-xr-x 2 oracle oinstall 4096 Mar 30 16:26 orcl.w
  drwxr-xr-x 2 oracle oinstall 4096 Mar 10 15:50 plargedb
  drwxr-xr-x 2 oracle oinstall 4096 Feb 6 16:20 plargedb.w
  -rw-r--r-- 1 oracle oinstall 696 Dec 28 16:58 sqlnet.log

In the example, oracle is the user and oinstall is the group.

If a user other than oracle installs the Oracle database, the
  avoracle program must use the
  --storageapp_username=username option. For example, if the user named test installs the Oracle database,
  username is test.
