On SAPJ2EE PL22 the installation and upgrade of
additional libraries as well as the maintenance of references has been changed for this and subsequent versions. I would like to share this
important information with you:
If you need to install or update libraries in the additional-lib
directory of the SAPJ2EE, this is no longer possible by just copying the
libraries to the additional-lib directories of the SAPJ2EE nodes.
Instead you have to open a telnet connection to the SAPJ2EE, jump to the
server node and use special commands for that. Please refer to the SAP
notes 743630 on how to install additional libraries and note 749154 on
how to maintain references on PL22 and subsequent versions.
For the installation of SSL support I had to update the IAIK libraries.
There is a special note on this topic too: 743277.
By the way: if you want to determine the patch level of the SAPJ2EE, you
have to look into the file
/usr/sap/<SID>/j2ee/j2ee_<instance>/cluster/server/managers/version.txt
and compare the version number to the list in SAP note 635453.
BR, Oliver
