IVTPRM00 (Communication Storage Manager)
IVTPRM00 sets parameters for the Communication Storage Manager (CSM). IVTPRM00 is read during CSM initialization when the first IVTCSM REQUEST=CREATE_POOL macro is issued. (VTAM® issues this macro when started.) The parameters can be changed without a re-IPL by editing the IVTPRM00 member and issuing the MODIFY CSM command with no command parameters specified.
