rman / NETBACKUP

I am getting an error message from RMAN stating it cannot communicate with the Netbackup server.

I was told there is a syntax to test communication to media manager on the server. Does anyone have that???

Here is the RMAN error message:

RMAN-03009: failure of backup command on ch01 channel at 06/07/2006 16:11:35
ORA-19506: failed to create sequential file, name="bk_7086_1_592502150", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
VxBSACreateObject: Failed with error:
Server Status: Communication with the server has not been iniatated or the server status has not been retrieved from the server.

how about the command you use

Here is the script:

ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
SEND 'NB_ORA_SERV=xxxxxxxxxxxxxxxxx';
BACKUP
SKIP INACCESSIBLE
TAG hot_db_bk_level0
FILESPERSET 5
FORMAT 'bk_%s_%p_%t'
DATABASE;
sql 'alter system archive log current';
RELEASE CHANNEL ch01;
ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
BACKUP
filesperset 20
FORMAT 'al_%s_%p_%t'
ARCHIVELOG ALL DELETE INPUT;
RELEASE CHANNEL ch01;
ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
BACKUP
FORMAT 'cntrl_%s_%p_%t'
CURRENT CONTROLFILE;
RELEASE CHANNEL ch01;
}

You don't mention what version of NetBackup you are using, but here is some good documentation on setting up NetBackup for Oracle ( VERITAS NetBackup (tm) 5.1 for Oracle).

Have you created a Policy on the NetBackup master server already? What version of Oracle are you using?
