eisa123 · 04-05-2016, 04:53 AM

Hi,

I have written a cron job that get executes everyday 10AM and call the ksh script but that ksh script shows echo but doesnot run java program, though when i run the same script manually it works fine and calls java program.Please help me urgently.

I am running the cronjob from folder /data02/Cognos10/sdk/java/CXOSrc/
which has run.sh and CXOJob java and class files.

Cron Job -
#!/usr/bin/ksh
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/data02/Cognos10/sdk/java/CXOSrc/

0 10 * * * /data02/Cognos10/sdk/java/CXOSrc/run.sh > /tmp/cron.log

run.sh

#!/usr/bin/ksh

export CRN_HOME=/data02/Cognos10

export JAVA_HOME=/usr/java71_64

export JAVA=$JAVA_HOME/bin/java

export JAR_HOME=$CRN_HOME/sdk/java/lib

echo $CRN_HOME

export CLASSPATH=$CLASSPATH:../Common:../HandlersCS:../Security:../ReportParams:../ReportSpec:../ViewCMReports:../ViewCMPackages:../log4j.properties:../ExecReports:../runreport:../Scheduler:../ContentStoreExplorer:/data02/Cognos10/sdk/java/lib/activation.jar:/data02/Cognos10/sdk/java/lib/axis.jar:/data02/Cognos10/sdk/java/lib/axisCognosClient.jar:/data02/Cognos10/sdk/java/lib/commons-discovery-0.2.jar:/data02/Cognos10/sdk/java/lib/commons-logging-1.1.jar:/data02/Cognos10/sdk/java/lib/commons-logging-adapters-1.1.jar:/data02/Cognos10/sdk/java/lib/commons-logging-api-1.1.jar:/data02/Cognos10/sdk/java/lib/dom4j-1.6.1.jar:/data02/Cognos10/sdk/java/lib/jaxen-1.1.1.jar:/data02/Cognos10/sdk/java/lib/jaxrpc.jar:/data02/Cognos10/sdk/java/lib/mail.jar:/data02/Cognos10/sdk/java/lib/saaj.jar:/data02/Cognos10/sdk/java/lib/wsdl4j-1.5.1.jar:/data02/Cognos10/sdk/java/lib/log4j-1.2.17.jar

echo $CLASSPATH

$JAVA -classpath "$CLASSPATH" CXOJob

echo $CLASSPATH

$JAVA -classpath "$CLASSPATH" CXOJob

Note that in the above you use the command $JAVA but have never SET the variable JAVA in the script. If JAVA is not set, that line starts the command

Code:

-classpath

with parameters. Most unlikely to do anything.

I am pretty sure I can see a "export JAVA=$JAVA_HOME/bin/java" in the script text.

@OP, you have 2 echo:

Code:

echo $CRN_HOME

...

echo $CLASSPATH

are the outputs of both displayed in the log file?

On second reading I see that. Missed it the first time. Thank you.

It may help to echo each environment variable to the log just before the command. That will allow you to double check the log against what you see on disk to ensure that it comes out correct.

I am able to fix the issue, gave absolute path.Cron was not recognizing relative url's, though created from same folder.Thanks.

ilesterg · 04-07-2016, 07:18 AM

Ooops. Totally missed that.

This would work too:

Code:

...
echo $CLASSPATH

$JAVA -classpath "$CLASSPATH" $CRN_HOME/sdk/java/CXOSrc/CXOJob
...

You can also mark this thread as solved once you are satisfied.
