DFHFCP

DFHFCP provides file services for application programs and for other CICS modules. These services include:

  • acquiring and releasing of the file storage by storage control

  • communicating with files defined in the file control table

  • logging changes to these files by DFHFCJ and journal control

DFHFCP handles requests that access data in VSAM files. Requests that access BDAM data are passed to DFHFCD. Requests that change the file state (for example, OPEN, ENABLE) are passed to DFHFCS, regardless of the access method.
