Problem summary
**************************************************************** * USERS AFFECTED: * * All CICSPlex SM V5R3M0 Users * **************************************************************** * PROBLEM DESCRIPTION: * * Abend ASRA/S0C4 may occur in a CMAS in method EYU0MOCS * * (MOCS) when the CMAS connects directly or indirectly to * * another CMAS. * **************************************************************** * RECOMMENDATION: * * After applying the PTF that resolves this APAR, all CMASes * * must be restarted. Note that the restarts do not need to * * occur at the same time. * **************************************************************** When a CMAS connects directly or indirectly to another CMAS, both CMASes need to build a resource table capability matrix for the partner CMAS, so that when CPSM resource tables are shipped between the two CMASes, table translation can occur if the CMASes support different versions of the tables. To build a capability matrix, method EYU0MOCS (MOCS) is called. MOCS will search through the existing capability matrixes that the CMAS has already built, to see if one is a match for the new partner CMAS. If so, it will assign the existing matrix to the new partner. If not, it will build a new matrix and assign it to the new partner. The capability matrixes are stored in the DAT component data cache, and are chained to each other. MOCS starts with the last built matrix, and chains from it to the first built matrix. Since the DAT data cache consists of two data spaces, DAT1 and DAT2, the matrixes can be allocated in either data space, depending upon available storage at the time of allocation. When this occurs, a logic error in MOCS will cause it to address invalid data when a matrix in one data space chains to a matrix in the other data space. This will most likely result in MOCS abending ASRA/S0C4.
Problem conclusion
MOCS has been updated to address the next compatibility matrix properly, when it is allocated in a different data space than the previous matrix.
