Java requirements
ObjectGrid can run on different versions of Java 2 Platform, Standard Edition (J2SE). ObjectGrid Version 6.1 supports J2SE Version 1.4.2 and above. For improved developer productivity and performance, use J2SE 5 or later to take advantage of annotations and improved garbage collection. ObjectGrid works on 32-bit or 64-bit JVMs.
ObjectGrid Version 6.0.2 clients can attach to an ObjectGrid Version 6.1 grid. Use ObjectGrid Version 6.1 clients for J2SE Version 1.4.2 or better clients. The only reason to use an ObjectGrid Version 6.0.2 client is for J2SE Version 1.3 support.
ObjectGrid is tested with a subset of the available virtual machines, however, the supported list is not exclusive. You can run ObjectGrid on any Version 1.4.2 or above, but if a problem on the JVM is identified, you must contact the JVM vendor for support. If possible, use the JVM from the WebSphere runtime on any platform that WebSphere Application Server supports.
Object Request Broker (ORB) requirements
The IBM SDK includes an IBM ORB implementation that has been tested with WebSphere Application Server and ObjectGrid. To ease the support process, use an IBM provided JVM. Other JVM implementations use a different ORB. The IBM ORB is only supplied out of the box with IBM provided JVMs. ObjectGrid requires a working ORB to operate. You can use ObjectGrid with third party ORBs, but if a problem in the ORB is identified, you must contact the ORB vendor for support. The IBM ORB implementation is compatible with third party JVMs and can be substituted if needed.
Java tuning
ObjectGrid requires little or no special JVM settings in most cases. If you have a large amount of objects being started in an ObjectGrid, adjust the heap size to an appropriate level to avoid running out of memory.
