APAR status
Closed as program error.
Error description
Unable to retrieve the PMI specification level from the target
server. The testcase works without problem when the target
server is 5.0, and it works without problem when connection to
4.0 but the specification levels are not retrieved (ie, only
return nodes, servers and pmi modules).
Local fix
A workaround is to compile the PmiClient using the 4.0's
perf.jar file in the classpath and run the client with that jar
before the 5.0 PmiClient files. However, 4.0 pmiclient has a
different constructor than 5.0. The main difference is that 5.0
allows users to specify different target servers ie (AE, AEs,
WAS50) while 4.0 only connects to 4.0.
Problem summary
****************************************************************
* USERS AFFECTED: WebSphere 5.0 PMI client API users *
****************************************************************
* PROBLEM DESCRIPTION: Unable to get instrumentation level *
* from WebSphere 4.0 *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Error while calling PmiClient.getInstrumentationLevel on
WebSphere 4.0 application server using WebSphere 5.0
PMI client API.
Problem conclusion
The error was due to missing serialVersionUID in the
WebSphere 4.0 class and the class was subsequently
modified in 5.0. The problem is fixed by adding
the WebSphere 4.0 serialVersionUID in WebSphere 5.0 class.
The class is com.ibm.ws.pmi.server.PerfLevelDescriptor.
