Error description
We are restarting our CMASes every month and when a CICS region is connected to CMAS1 before CMAS1 is restarted and if it connects to CMAS2 after the CMAS1 was restarted then the message "EYUBN0099I Resource creation processing complete" is missing in the regions and no BAS resources were created in those regions. When we restart the CICS regions in the old LPAR, the issue gets resolved. The failure scenario is : - Two CMASes: CMAS1 and CMAS2 - Two MASes: MAS1 connected to CMAS1 on LPAR1 MAS2 connected to CMAS2 on LPAR2 . Steps: . - Bring up the two CMASes and two MASes. - Everything is fine, and I can see EYUBN0099I message issued for the two MAS regions. - Bring down CMAS1 and MAS1 - Restart CMAS2 while MAS2 remains active - Bring up CMAS1 - Bring up MAS1 to a different LPAR, and connect to CMAS2. - We can see EYUBN0099I message is missing, and no resource was installed to MAS1. This problem was caused by the CPSM warm restart of CMAS2, meaning that all connections to CMAS2 were not closed before it was restarted.

Problem summary
**************************************************************** * USERS AFFECTED: All users of CPSM V5R4M0 and V5R5M0. * **************************************************************** * PROBLEM DESCRIPTION: When a MAS region was restarted and * * connected to a different CMAS, which * * had recently performed a CPSM warm * * restart, the BAS resource definitions * * might fail to install, and the * * following message is missing from the * * MAS job log: * * * * EYUBN0099I applid Resource creation * * processing complete. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves * * PH07645, all CMASes must be recycled to pick * * up the new code. Note that the restarts do * * not need to occur at the same time. * **************************************************************** During MAS initialization, method EYU0TSSC (TSSC - Topology CICS System Start Event Method Receiver) is driven on the connecting CMAS to perform the topology connect process for the MAS region. This includes automatic resource install if needed and method EYU0TSCI (TSCI - Topology Autoinstall Resources Method Receiver) is eventually called for the resource installation. Before calling TSCI, various status flags of the MAS region are inspected to determine whether the MAS region is connecting to this CMAS for the first time. If so, then resource installation is performed. Otherwise, TSCI will be called with different options and resource installation will be ignored. When a MAS region is restarted, and connected to a different CMAS which had recently performed a CPSM warm restart, this processing may fail. As a result, no BAS resource definitions are installed into the MAS region and message EYUBN0099I is not issued.
Problem conclusion
Method EYU0TSSC has been updated to make sure the BAS resource definitions are installed properly.
