Closed as program error.
Error description
When a broker is configured with global cache using 'default' policy the execution groups which act as 'Client' may end up in a loop of error BIP7156W during startup. The error BIP7156W is typically generated when the grid does not exist on the server (catalog/container) side. The containers have the grid definition. Therefore, until a container is started there are no grids defined. Therefore, if an execution group which is acting as a 'client' tries to connect to the grid before it is fully initialized, the client EG may end up in a continuous loop of error BIP7156W and not connect to the grid until the EG is restarted.

Problem summary
**************************************************************** USERS AFFECTED: All users of IBM Integration Bus v10.0 using Global Cache with default policy. Platforms affected: MultiPlatform, z/OS **************************************************************** PROBLEM DESCRIPTION: When an Integration Node is configured with global cache using 'default' policy, any integration server that acts as a 'client' to the global cache may end up in a loop continually issuing BIP7156W errors during startup. This problem occurs in a situation because the integration server tries to connect to the global cache grid as a client before the grid in the container server is initialized. There are a number of resource name changes between WebSphere Message Broker and IBM Integration Bus Version 9.0.

Problem conclusion
The product now allows a longer time delay (30 seconds) for the client integration server to attempt connection with the global cache grid. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.9 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
