Welcome back at the SAP on IBM i update blog series!

It’s about time to restart posting heads up information from the development team now that the discussion forum seems to recover after the big SCN switch back in March. The first topic I’d like to bring to your attention is again about switching to SAP JVM 4. It has already been addressed in a former posting and in the entry page of our SAP on IBM i space. Reason for iterating on this is the tight schedule you have and may not quite be aware of.

SAP JVM 4 replacing vendor JVMs

SAP published its Java 1.4 based JVM in August 2011 with the intention to replace all vendor 1.4JVMs for SAP NetWeaver 6.40 and 7.0x based applications. Starting October 2012, SAP will no longer provide support for vendor 1.4 JVMs. By then you should have switched your IBM Java 1.4 VMs to SAP JVM 4. This date is only half a year from today.

Benefits for you are the extended support lifecycle for your SAP Java applications and an equal or better runtime performance compared to IBM IT4J or classic JVM. The administration of SAP JVM 4 can still be performed with the known JVM CONFIGTOOL.

    

You may have noticed that a colleague of mine provided a presentation SAP JVM 4 and IBM i that guides you through the necessary steps to perform the switch procedure on our platform. The presentation contains links to the SAP JVM and the switch tool as well as to all relevant SAP notes in this context.

Feedback more than welcome
