Set the appropriate ORACLE_HOME, ORACLE_SID & PATH environment variables for each database and issue the following:

sqlplus / as sysdba
startup

my bashrc file has oracle_sid=orcl which is for the DB which was setup when i installed Oracle, i created a 2nd DB with DBCA, now i want to create a Recovery catalog for DB A, which will reside on DB B, for that to happen i have to startup DB B as mount exclusive & that is where i am having a problem, the dbstart script starts both DBs at the same time, so i want to start the desired DB from sqlplus command line! so please elaborate further !

thanx in advance

What part of the above do you NOT understand?
Do you UNDERSTAND what the environmental variables above are used for?
If NOT, then visit http://tahiti.oracle.com & Read The Fine Concepts Manual.

Who said anything about ORAENV?

Do you know how to set/change the value of an environmental variable?

Which environmental variable controls which database is to be accessed?

lets get it clear, i already know how to connect to different Databases from shell command line, since my dbstart script starts both databases, & i am guessing you are talking abt setting environment variables in ~/.bashrc file, !!! my problem is connecting from SQLPLUS command line when i type startup on sqlplus it fires up the default database which was created when i installed Oracle 10g ,
so please elaborate extensively !!!

you are help will be kindly appreciated!?!?

Write 2 scripts per database, start_db1.sh, stop_db1.sh and same thing for db2.
start_db1.sh
ORACLE_HOME=<oracle home for db1>
export ORACLE_HOME
ORACLE_SID=DB1
export ORACLE_SID
PATH=$ORACLE_HOME/bin;$PATH
export PATH
sqlplus <<EOF
connect / as sysdba
startup
exit
EOF

Same thing for stop
Same thing for DB2.

Now you just have to call each script when the corresponding database you want to start/stop.

Regards
Michel
