RMAN connecting to wrong target

Wh开发者_开发知识库en I run rman target / @mydb nocatalog cmdfile=%commands% msglog=%logfile%, I see connected to target database: OTHERDB (DBID=3786352837, not open).

Help!

suppose your target database SID = HR_VMC, to connect this target database issue the following commands to connect it using RMAN

export ORACLE_SID = HR_VMC
sqlplus
SQL> connect / as sysdba
SQL> select name from v$database;

it shows the HR_VCM open another terminal and from the comman line issue the following RMAN command

RMAN target /

Setting environment variable ORACLE_DB to the target database helps the cause.

Set ORACLE_SID=mydb
