In the spotlight

1. Potential security vulnerability when using Web based applications on IBM WebSphere Application Server due to Java HashTable implementation vulnerability (PM53930)
   Potential Denial of Service (Dos) security exposure when using Web based applications due to JavaHashTable implementation vulnerability.
   
   
2. Education: Join Ask the Experts on Installation in WebSphere Application Server
   You are invited to an IBM Ask the Experts discussion about Installation in WebSphere Application Server on 15 March 2012 at 11:00 AM EDT. This Ask The Experts Session covers common questions and issues in the installation of WebSphere Application Server V8 and the included packages using installation manager. The session also answers questions regarding WebSphere Application Server V7 and V6.1, although the main focus is on the latest release.
   
   
3. Reminder: End of Support for IBM WebSphere Application Server V6.1 is 30 Sept 2012
   This is a reminder of the upcoming WebSphere Application Server V6.1 products' End of Support date of 30 September 2012.
   
   
4. Knowledge Collection: Migration planning for WebSphere Application Server
   A focused compilation of links to documents and resources to help you plan and perform your migration to IBM WebSphere Application Server.
   
   
5. Required fixes for migration to Websphere Application Server Network Deployment Version 7.0
   Due to serialization differences in certain classes in the Websphere® Application Server 6.1.x Service Release stream, certain Fix Pack and Interim Fix levels are required to successfully migrate to Websphere Application Server Network Deployment Version 7.0.
   
   
6. An OutOfMemoryError produces a system dump starting in WebSphere Application Server 8.0.0.2
   Why does an OutOfMemoryError (OOM) create a system dump starting in WebSphere Application Server (WAS) 8.0.0.2?
   
   
7. Troubleshooting native memory issues
   There are two types of memory problems which will throw an OutOfMemoryError: If a Java™ object cannot be allocated or if there is no more memory available for native code allocations (c malloc) or threads. The first case is called Java heap exhaustion and the second, a native memory issue. Finding the users of native memory can be a lengthy process, as there is no way of knowing which code allocated the native memory. There are no comparable heapdumps for native memory, so we have to use trial and error, going through each of the potential native memory users until we find the one that is causing the problem. Following are the most common causes of native memory issues in WebSphere Application Server, so you should try them first. They are all trying to reduce the native memory used (the native memory footprint) so both the java heap memory and native memory can fit in the address space for the application server process. If these steps do not solve your native memory issue, IBM support will guide you through the rest.
