Hi,

I am using Oracle Database 10g.

I have 1 OS user who is the owner of 2 Oracle Instances.

Each time i have to say export ORACLE_SID=test, ORACLE_SID=prod

I am writing a shell script (in a menu) for example to export test and prod databases.

In the shell script i have
exp system/testpassword full=y file=/test/export.dmp log=/test/export.log
&
exp system/testpassword full=y file=/prod/export.dmp log=/prod/export.log but i have to export the ORACLE_SID before.

How can i include this in the shell script?

Thanks
Dirish

Hi Michel,

Thanks for the advice. Actually the client wants to go with exp/imp.

Blackswan,
The first line in red is not working

vi exp_test.sh
export ORACLE_SID=test
echo "exp system/manager full=y file=/d02/exp_tst.dmp log=/d02exp_tst.log statistics=none" | su - ora10g

Please advise

When you "su -" you lose the current context and so the value of ORACLE_SID.
Put each export statement in a script and start this sript:

exp_test1.sh
export ORACLE_SID=test
exp system/testpassword full=y file=/test/export.dmp log=/test/export.log

exp_test.sh
su - ora10g -c exp_test1.sh

Regards
Michel

Hi Michel,

Thanks for the update.

Actually I have put a menu for the export, as shown below

# su - sysadmin

7. Full Database Export - Prod Database
8. Full Database Export - Test Database

0. EXIT

Choice :

So, in

exp_test1.sh must be like this?

echo "export ORACLE_SID=test" | su - ora10g
echo "exp system/manager full=y file=/d02/exp_tst.dmp log=/d02exp_tst.log statistics=none" | su - ora10g

exp_test.sh
su - ora10g -c exp_test1.sh

No, exp_test1.sh should be as I posted.
More, if your Oracle environment is correct that is oratab is filled and so on, it should be:

export ORACLE_SID=test
export ORAENV_ASK=NO
. oraenv
exp system/testpassword full=y file=/test/export.dmp log=/test/export.log

Michel

Please advise

export ORACLE_SID=test

"export" is bash command & will fail when invoked by Korn shell (sh)

ORACLE_SID=test
export ORACLE_SID

above will always succeed as as not using C-Shell
