rman backups using networker

[penzk001]

Good morning,

We have just configured an Oracle 8i (parallel server) to perform open backup using rman. We are using Oracle 8i 8.1.7.0.0, AIX 4.3.3, Legato 6.1.1 Build 238, Module Reports NMO v3.5.0.0.

Since the database is still relatively small, we have decided that for two months after the deployment, we will perform full database backups.

When the backup is executed as a cron job as follows:

The backup performance is very poor, i.e. 50 to 88 KB/s and the following error is given:

RMAN-08522: input datafile fno=00007 name=/dev/rCHR_drsys1.dbf
RMAN-03026: error recovery releasing channel resources
RMAN-08031: released channel: ch1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

ORA-19511: Unable to connect to media index server netf1-LT
RMAN-10031: ORA-19583 occurred during call to DBMS_BACKUP_RESTORE.BACKUPPIECECREATE

Recovery Manager complete.


Script used:

replace script backup_db_full {
allocate channel ch1 type 'SBT_TAPE'
parms 'ENV=(NSR_SERVER=netf1-LT,
NSR_DATA_VOLUME_POOL=Default)';
backup
full
tag bk_db_full
filesperset 4
format '%d_%t_%s_%p'
database; # backup up db + control which does not know about this backup
backup
current controlfile;
release channel ch1;
execute script backup_redo_logs; ## backups up redo logs
}

Anyone knows what can I check ?

People,

Problem solved as the backup there was an application, problem that was causing the utilisation to the system to be 100 %.
