hi, Error 2400 indicates that you don't have a license file or a valid license file. What is your TDPO level? Backup scripts vary depending on your TDPO and Oracle level. In general, run { # for TDPO 2.1.x allocate channel t1 type 'sbt_tape' parms 'ENV=(DSMI_CONFIG=/home/oracle/dsm.opt)'; # for TDPO 2.2 #allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/orc8db/dbs/t1/scripts/tdpo.opt)'; backup # if O8.1.x format string is not needed format 'df_%t_%s_%p' (database ); } regards, Thiha Can someone send me an example of a simple RMAN script for use with TSM. We run AIX 4.3.3, Oracle 8 and TSM client 3.7.2, so if someone has a similar setup, great, but anything wuld help I guess. we installed the TDP for oracle recently, but seem not able to do RMAN backups with TSM, the backup/archive client is ok. If the message below sounds familiar to someone please let me know.
