APAR status
Closed as program error.
Error description
For a valid domain chosen on the WebSphere eXtreme Scale Monitoring Console, consisting of catalog servers hosted within the WebSphere Application Server ND environment, the connection status may appear as "Connection Error," with grid statistics failing to appear for the domain. The following exceptions may also appear in connection with the above symptoms: STDERR ﾃ ﾃ info ﾂ ﾨUpdate connection info for /storage/current/domain 2011-01-11 13:52:48 zero.core.context.zones.JavaGCSerializer::deserialize Thread-1 SEVERE ﾃ CWPZC0029E: Unable to serialize key < ﾃ B@45cb45cb> the ser zone. ﾂ ﾨ java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInpu tStream.java:2292) at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectI nputStream.java:2761) at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.jav a:791) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:291) at zero.core.context.zones.JavaGCSerializer.deserialize(JavaGCSeria lizer.java:71) at zero.core.context.zones.GCFileStore.read(GCFileStore.java:432) at zero.core.context.zones.GCFileStore.load(GCFileStore.java:384) at zero.core.context.zones.PersistentZoneHandler.get(PersistentZone Handler.java:139) at zero.core.context.zones.support.ZoneHandler2Wrapper.get(ZoneHand ler2Wrapper.java:101) at zero.core.context.Context.zput(Context.java:351) at zero.core.context.zones.support.ZoneHandler2Wrapper.zput(ZoneHan dler2Wrapper.java:53) at zero.core.context.Context.zput(Context.java:337) at zero.core.context.GlobalContext.zput(GlobalContext.java) at com.ibm.ws.xs.app.DomainConnectionUpdater.setConnectionInfo(Do mainConnectionUpdater.java:135) at com.ibm.ws.xs.app.DomainConnectionUpdater.run(DomainConnection Updater.java:78) at java.lang.Thread.run(Thread.java:735) ...

The exceptions occur when the runtime attempts to deserialize information about catalog servers for the chosen catalog service domain that is persisted to the following files in the file system: <eXtreme_Scale_Install_root>/ObjectGrid/console/xs.app/.zero/app liancezoneStore/catalogServers.ser <eXtreme_Scale_Install_root>/ObjectGrid/console/xs.app/.zero/sto ragezoneStore/wxs/catalogServers.ser The file contents might be corrupted. As a result, the connection status to a selected, valid catalog service domain might erroneously diplay as: "Connection Error". Data grid statistics also might not display for the catalog service domain.
Problem conclusion
The runtime was corrected to store the catalog server information in a temporary storage location instead persisting it to a file. This APAR is anticipated to be included in WebSphere eXtreme Scale Version 7.1.0.3.
Temporary fix
As a temporary workaround, you can stop the console, delete the .ser files, and restart the console.
