    Please have a look at the sample scripts as suggested before.

    When triggered from the master server, the script is run by root user. root user does not have oracle db rights. There needs to be a test for username, if not oracle, then 'su - oracle' to run rman commands.

    Extract from sample script (which is missing in your backup script):

    # Determine the user which is executing this script.
    # ---------------------------------------------------------------------------
    CUSER=`id |cut -d"(" -f2 | cut -d ")" -f1`
    ....
    ...

    # Initiate the command string
     
    if [ "$CUSER" = "root" ]
    then
        su - $ORACLE_USER -c "$CMD_STR" >> $RMAN_LOG_FILE
        RSTAT=$?
    else
        /usr/bin/sh -c "$CMD_STR" >> $RMAN_LOG_FILE
        RSTAT=$?
    fi

    Check the output of the rman script. It should be located in /oracle/tbsbin/ unless you've specified a non-default value for logs. You can also log into the client and run the script manually. That would show what's happening.

    I suspect something wrong with the script. Did the Oracle dba use the sample script or provided own script? I am no Oracle expert, but we know from the NBU sample scripts what it should look like. Please copy the script and the output file to .txt files and upload as File attachments.

    chmod -R 755 /usr/openv/netbackup/logs

    provide your RMAN script as text file. Is it standalone DB or RAC DB ?

    chmod needs to be run as root, so, changing permissions to 755 will only give root write permission to log folders and backups will fail when folders exist and oracle user cannot write to the folders.
    755 is already the default.

    Log folders need to be changed to 777 or else owinership of log folder need to be changed to oracle user, but NOT bpcd log. This log needs to be written to by root.

    I am surprised that the script reported success when it actually failed. Did your dba look at the output? It did not get past the 'send' statement: "RMAN-03002: failure of send command at 10/13/2015 09:57:46 ORA-19559: error sending device command: NB_ORA_SERV=master.domain.com,NB_ORA_POLICYt=E_Test_ORA_UNX_Full_AAA ORA-19557: device error, device type: SBT_TAPE, device name: ORA-27194: skgfdvcmd: sbtcommand returned error ORA-19511: Error received from media manager layer, error text: Unknown command key " Your dba will need to fix the syntax issue in the script. I am not close to a system to compare with the sample scripts, but your dba should be able to spot the mistake.

    Hello,

     

    it looks that return code management is missing in the script, so parent job did not get proper error code. Refer to script templates in samples subdirectory.

    I am surpraised too, Backup should fail instead of success.

    I have modified your backup script as below, Use below script and let me know the result

    NOTE : Change NB_ORA_SERV and NB_ORA_POLICY according to your environment.

    run

    {

       allocate channel ch00 type 'SBT_TAPE';
       allocate channel ch02 type 'SBT_TAPE';
       send 'NB_ORA_SERV=master.domain.com,NB_ORA_POLICY=E_Test_ORA_UNX_Full_AAA';
       crosscheck backup;
       crosscheck archivelog all;
       backup current controlfile;
       backup as COMPRESSED BACKUPSET database plus archivelog;
       release channel ch00;
       release channel ch02;

    }

    Hi,

     

    Please use the sample scripts. If the DBA wants to change them then he'll be responsible for the script.
