When I run the jython script using wsadmin command on WAS 8.5 ND it shows me below messages:

[wsadmin] *sys-package-mgr*: processing modified jar, '/opt/IBM/WebSphere/AppServer/java_1.7_64/lib/ibmorbtools.jar'
[wsadmin] *sys-package-mgr*: can't write cache file for '/opt/IBM/WebSphere/AppServer/java_1.7_64/lib/ibmorbtools.jar'

I have provided the 777 permission to the specified directory. How can I remove these messages.

  • I believe the cache files are written to PROFILE_HOME/temp or PROFILE_HOME/wstemp, so you might check the permissions of your PROFILE_HOME directory. – Brett Kail May 02 '15 at 22:48

This warnings usually look like this:

...
*sys-package-mgr*: processing modified jar, '/usr/IBM/WebSphere/AppServer/plugins/org.eclipse.core.runtime.compatibility.jar'
*sys-package-mgr*: can't write cache file for '/usr/IBM/WebSphere/AppServer/plugins/org.eclipse.core.runtime.compatibility.jar'
*sys-package-mgr*: can't write index file

This are confusing. Source of errors is jython underlying wsadmin. Jython is scanning WebSphere jars, trying to create a pkc file for an each scanned jar and finally is creating or updating the package.idx file. Warnings are raised as user running jython/wsadmin has no proper file permissions.

User running wsadmin must have read and write permission for jython cache folder and all contained files. Default cache folder is temp/cachedir within WAS profile. For example my "Deployment manager" named Dmgr01 has jython cache folder within:

${WAS_INSTALL_ROOT}/profiles/Dgmr01/temp/cachedir

Once one proper rights are given "can't write cache file for" and "can't write index file" warnings will be gone. And "processing modified jar" will be raised whenever jars are updated or temp folder cleaned which is rare event for WAS installation.

If wlst works before and doesn't work now, this error means the temp directory "/tmp/wlstTemporacle/packages" are corrupted.

If you go into "/tmp/wlstTemporacle/packages", you will lots of *.pkc files are duplicated with a "$1" in it's name. In your case, the file "ibmorbtools.pkc" will have a crapy sibling "ibmorbtools$1.pkc" there. This is not correct and it means this directory is corrupted.

The solution is to totally remove directory "/tmp/wlstTemporacle/packages", or even entire "/tmp/wlstTemporacle". And then rerun wlst.sh, you will see a new directory structure is created and all *.pkc are copied over correctly. Your above error message will go away.

Notes: In my case, this is oracle WebLogic 10.x.x.x running on Linux. Its WLST is Jython apps. The temp dir for java is point to "/tmp/wlstTemporacle". If your case is different, the easiest way to determine where is temp directory for your environment is to do a full search for file "ibmorbtools.pkc". It's name come from your error message which is "ibmorbtools.jar", just postfix are different.

Hopefully, this will help!
