I'm testing rman on a server to put the server in production. My problem is when you have got media failure on system datafile and consequently the system tablespace.
The problem is:
when simulating removing the system data file from the disk after taking a level-0 backup. The ramn is not able to connect the target database catalog (when database is down) because the server can not be mounted and I got the following error message:
Recovery Manager: Release 22.214.171.124.0 - Production
RMAN-06005: connected to target database: SOLDB (DBID=2945300576)
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04004: error from recovery catalog database: ORA-01033: ORACLE initialization or shutdown in progress
The problem exists, without opening the database you are not able to connect to database catalog.
And with system datafile missing you cannot open the database from another interface like sqlplus.
Do you how to handle the situation.
