root, oracle,rdbms and sqlplus

[Scott E Smith]

We are trying to run an sql query as root to get the number of current sessions on the database. Normally we run this as oracle but now we need it as root for monitoring. I seem to be having environment issues as the commands do not work....
su oracle -c /../../..sqlplus sess.sql ....
I get sqlplus not found even after setting path etc.....

PATH=$PATH;/opt/oracle/8.1.7/bin/;.
ORACLE_SID=$1
ORACLE_SCRIPT=/opt/oracle/admin/script
ORACLE_HOME=/opt/oracle/8.1.7
export ORACLE_SID
export ORACLE_HOME
export SESSLOC=/opt/oracle/admin/script/sess.sql
export SQL=/opt/oracle/admin/script/sqlplus.sh

SES=`su oracle "$SQL system $SESSLOC |grep rows |cut -d " " -f 1"`

echo "The number of active sessions is $SES"
Any ideas? Thanks.

As Oracle, do "env |grep -i oracle" and compare this against the same output when logged in as root. There's got to be something missing from root's env.

Try "su - oracle ....."

the "-" tells su to execute the login environment.

This helps (no hope needed !)

LD_LIBRARY_PATH ??

You do not want to use su - oracle to read Oracle's .profile unless you surround all the interactive commands like tset, stty, and tabs with
if [[ -t 0 ]]
then
...
...
fi

The better way is to create a file (e.g. /usr/local/bin/oraenv.sh) and let your script and oracle's .profile source it via
. /usr/local/bin/oraenv.sh

This will insure that both your scripts and oracle's .profile will use exactly the same environment. NOTE: This sources file must not contain an exit or return statement.

Your specific problem is that you used semicolons rather than colons in the construction of your PATH.

I extracted some code from our auto-shutdown
oracle database script:

if [ "$LOGNAME" = "root" ]
then
echo "User root shells to oracle"
/usr/bin/su - oracle -c "/usr/contrib/bin/shut.oracle"
exit 1
fi
