Connecting to multiple oracle databases from unix

[nunrgleo]

Hi all,
I need to write a script that logs into several oracle databases in a sequential manner from a unix box using different login and password e.g sqlplus found/duckl@dnd007 and many more databases to check the logon details work and database is up. At the moment i've got it all hardcoded in a script e.g
echo 'testing xxx'
sqlplus xxx/yyy@xxx
.
.
.
echo 'testing aaa'
sqlplus aa/yyy@aaa

but the problem is i have to type exit at the sqlplus prompt all the time and this can be pretty boring as i've got a long list.
Thanks for the help.
Cheers.

Here is the code (I put it in a script called check_mult_db_s tatus.sh) that you are looking for:

echo Testing db1
sqlplus -s u1/p1@db1<< EOF
quit
EOF
echo Testing non-existent db2
sqlplus -s u2/p2@db2<< EOF
quit
EOF
echo Testing db1
sqlplus -s u1/p1@db1<< EOF
quit
EOF

When you execute this script, you will see less visual noise (as a result of the -s parameter) and will still see errors at the appropriate place, as you will see below in the execution dialog:

$ ./check_mult_db_s tatus.sh
Testing db1
Testing non-existent db2
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified



ERROR:
ORA-01005: null password given; logon denied


Testing db1
