Hi ,

I am experiencing the below issue while i use global cache in 2 different servers. (Works fine in Single broker/Single machine).

We have 2 production servers. The requirement is to maintain a Global Cache. I have created a policy file which contains entries for 2 brokers with port information and hostname information.

I ran the command mqsichangebroker in both of the broker with -b flag and command successfully completed.

When i try to access the map (MbGlobalMap globalMap = MbGlobalMap.getGlobalMap("map1")) the flow hangs for few seconds and throws exception.
When i checked in the syslog i can able to see the below entries.

Mar 6 19:22:51 mcnbadevint WebSphere Broker v8001[26341]: (Test.SMSC_GW_MT)[8]BIP7156W: This execution group has failed to establish a connection to the broker global cache. The attempt to connect to the remote server components has now been running for '1385' seconds. The connection is being made using the connection string 'Server1HostName:3000,'Server2HostName:3020'. : Test.a12bff3d-3d01-0000-0080-9f3b9683c15a: /build/slot1/S800_P/src/DataFlowEngine/NativeTrace/ImbNativeTrace.cpp: 793: startConnection: :

Both the servers and able to access each other via Ping, Telnet.And also the ports am using for Catalog and Container servers are free and available for use.

Kindly put a light on this exception. And also should i need to configure anyhting else in the servers other than the mqsichangebroker command.?

Regards,
Tony Thomas

Hi Tony,

The first thing to check here is that both of your catalog servers are available.
Can you look in the syslogs around the time you restarted the brokers (after mqsichangebroker)? There will be a BIP7162I in each if they have started successfully. Otherwise there should be BIP7160 errors.
If they have started successfully - then an "mqsicacheadmin <brokername> -c listHosts" (on either machine) would show the overall shape of the grid.

Regards,

James
