    I am having problems with my first installations of Oracle iDA and RMAN. Simpana version 9. Client OS RHEL 5.5 + glibc2.5

    It opens the channel with SBT but it gets no good answer from the backup-system. Error messages from the RMAN-log as follows:

    RMAN-00571: ===========================================================
    RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
    RMAN-00571: ===========================================================
    RMAN-03009: failure of allocate command on ch1 channel at 01/12/2011 16:32:58
    ORA-19554: error allocating device, device type: SBT_TAPE, device name:
    ORA-27000: skgfqsbi: failed to initialize storage subsystem (SBT) layer
    Additional information: 7111
    ORA-19511: Error received from media manager layer, error text:
       SBT error = 7111, errno = 0, sbtinit: system error

    I don't get any leads by looking in the CommServe-logs.

    I have also done a successful Oracle iDA installation on a Windows Server 2003 R2. Configured in the same way as the one on the RedHat-server.

    Anyone got a clue?

    Typically we see these errors when the CV software is installed, and the group security was selected during install without consideration of the primary group for the Oracle user.   The Oracle iDA requires that the oracle user (configured in the iDA) MUST have access to the CV software structures which are owned by "root".  The way this is accomplished is by virtue of Unix's Group access, where when installing CV, the primary group for oracle is specified during the install, and hence the oracle user can access the CV structures using the group permissions.  Typically this group would be set to either "oinstall" or "dba"


    If the CV software was installed without setting the "group" security this will not be a problem as the software is then installed with all permissions so the oracle user would have access via the "other" permissions in Unix.


    Create a file in the /tmp directory called libcvobk.log with permisions "777" and run another backup.  After the failure take a look at the /tmp/libcvobk.log to see if there are any permissions errors in the log.   If there are, take a look at the file pkginfo which is located under the Base directory of the CV software install.  In that file is a "GALAXY_GROUP" parameter.  Compare that with what the primary group is for the oracle user.  If they are not the same, then I would recommend re-installing ALL the CV software being sure to use the primary group for the oracle user for the install of the CV software.   If you can't re-install, you can open a support ticket and one of our engineers can reconfigure the group without having to re-install the agent.

    It was usrgrouprights that was the problem. I did a test to reinstall the OracleAgent but that did'nt help. But after unistall all CV-software from the client an reinstall the File-agent and the Oracle-agent with the unix usergroup set to oinstall it worked fine.

    Thanks alot!
