Error description
Your CICS region starts and begins to connect to the CPSM CMAS. The messages seem to indicate that things are going well, but you quickly see a message similar to the following: . EYUNL0906E masname The CMAS has initiated a shutdown of the MAS agent. See the CMAS job log for additional information. . Over in the EYULOG for the CMAS that this MAS was trying to connect to, you see a sequence of messages similar to the following: . EYUXL0006I masname BAS initialization has started. EYUTS0001I cmasname Topology Connect for masname Initiated - APPLID(masname) CICSplex(plexname). EYUXD0002I cmasname Delete CONTEXT(plexname) MAJOR_ID(resourceid) MAJOR_NAME(resourcename) MAJOR_VER(1) MINOR_ID(NONE) MINOR_NAME(NONE) MINOR_VER(NONE) By User(username) On System(cmasjobname) Date(date) Time(time). EYUTS0002E cmasname Topology Connect for masname Failed - APPLID(masname) CICSplex(plexname). . An SVC dump is not produced, however an exception trace is written in the CMAS. Looking at the trace, you will see the problem during Topology CONNECT reflected in the following: . Task Mtd Prev Tran Obj Level Pt-ID Debug UOW 12345 BMES TSCI TSSC BAS Excp 3 BMESXDGR CPSM 12345 TSCI TSSC TSSC TOP Excp 2 TSCIXQDQ CPSM 12345 TSSC XLOP TSSC TOP Excp 4 TSSCTSCI CPSM . The first failure, with Debug Text of BMESXDGR, is a call from method BMES to XDGR to read a record from the EYUDREP repository. This is to build the Install Queue during the CONNECT process for the MAS. In the trace you can see that method BMES gets RESP=2, RSN=3. This is Exception Point #3, corresponding to BMPI_XDGR_NRF, for "Repository Get no record found". . There is a small timing window that exists where an administrator may be deleting a resource from CPSM BAS at the same time that a MAS is CONNECTing to the CMAS. During that window of time, the in-storage list of resources to be installed by BAS into the MAS may contain a resource that has already been deleted from the CMAS EYUDREP. . .

Local fix
Restart the MAS or try using COLM transaction in the MAS to restart the MAS agent.
Problem summary
**************************************************************** * USERS AFFECTED: All users of CPSM V5R2M0, V5R3M0 and V5R4M0. * **************************************************************** * PROBLEM DESCRIPTION: When BAS resource management is used, * * MAS regions will install CICS resources * * during startup initialization. If a * * CICS resource definition is deleted in * * the data repository during the MAS * * installation, the MAS may fail to * * initialize, causing the MAS agent to * * shut down. * * Similar information may appear in the * * logs of CMAS and MAS: * * EYUNL0906E masname The CMAS has * * initiated a shutdown of the * * MAS agent. See the CMAS job * * log for additional * * information. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, 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 CMAS initialization, a CMAS generates a list of resources that will be installed during the initialization of each MAS. If a resource is deleted from the data repository, the resource list is updated accordingly. During MAS initialization, the CMAS reads the resource list from the data space to obtain a list of resources to be installed. It then reads the detailed resource definition from the data repository, and sends it to the MAS for resource installation. In the reported problem, a resource was deleted from the data repository, but a MAS initialized before the resource list (held in the BAS data space) could be updated. The CMAS was unable to obtain the complete resource definition from the data repository, which caused MAS initialization to fail, and the MAS agent to automatically shut down.
Problem conclusion
CICSPlex SM has been updated so that MAS initialization will continue. Other resources will be installed; the MAS agent will not be shut down. A new message, EYUBM0349W, will be written to the CMAS EYULOG to aid debugging. The message indicates which resource could not be read from the data repository. The CICSPlex SM Knowledge Center will be updated with new message: EYUBM0349W The deftype (defname) record for CICSplex(plexname) cannot be found in Data Repository.
