NAME : HCPPTRMB DESCRIPTION: Page Table Resource Management block DSECT : PTRMB FUNCTION : Contains information used in managing (allocation and re-organization of) a PTRM address space. LOCATED BY : ASCTYPTR field of ASCBK points to a CAABK. This control block starts at CAAFSI (function specific information) section of the CAABK. CREATED BY : HCPHRPIN, when creating a PTRM address space DELETED BY : Once created it is never deleted. SERIALIZED : RELOCATION CONSIDERATIONS : None COMMENTS : The PTRM reorganization fields were moved from this PTRM specific control block to the more general, CAABK. This was because HCPHSURO, HCPHAMAP and HCPHAMDP now manage other System Utility address spaces (like the ISFC address space, ASCUCONN in ASCSUTYP). |
