Problem summary
**************************************************************** * USERS AFFECTED: Users of the default messaging provider for * * IBM WebSphere Application Server * * Version 6.1 and Version 7.0 * **************************************************************** * PROBLEM DESCRIPTION: Excessive creation of workspaces by * * the bus getMENameByUuid method * * increases the risk of WKSP0009E and * * WKSP0011E errors * **************************************************************** * RECOMMENDATION: * **************************************************************** The default messaging provider has a method called getMENameByUuid, which is used to translate an internal UUID to a messaging engine name. The method is used when outputting information messages, such as CWSIP0382I. It is also used then creating the message for various exceptions. The internal operation of this method involves a number of separate queries to examine the configuration documents of the application server. The code uses a different configuration service Session object for each call, resulting in a large number of workspaces being created. The configuration service code has a limitation that means that WKSP0009E and WKSP0011E errors occur when more than one workspace is created by separate threads/processes in the same node, in the same millisecond. The combination of the frequency of calls to the getMENameByUuid, combined with the number of Sessions created internally by this method, creates a risk of encountering WKSP0009E and WKSP0011E errors.
Problem conclusion
The fix for this APAR reduces the likelihood of encountering the WKSP0009E and WKSP0011E errors, by changing the operation of the getMENameByUuid method to use a single Session object, rather than creating multiple Sesssion objects (and hence multiple workspaces). However, it does not eliminate the possibility of encountering WKSP0009E and WKSP0011E errors, as the configuration service limitation regarding creation of workspaces in the same millisecond remains, and the getMENameByUuid method might still be called on multiple threads at the same time. In cases where WKSP0009E and WKSP0011E errors still occur from getMENameByUuid after the fix for this APAR is applied, the following line can be added to a sib.properties file to prevent the getMENameByUuid method from creating workspaces at all. With this property set to true, informational messages and exceptions from the default messaging provider contain the UUID of the messaging engine, rather than the name. sib.admin.disableMENameLookupsForMsgs=true See the "Setting tuning properties by editing the sib.properties file" topic of the WebSphere Application Server information center for information on setting properties in the sib.properties file. The fix for this APAR is currently targeted for inclusion in fix pack 6.1.0.37 and 7.0.0.15.
