DFHWOSM FUNC=OPEN macro
The DFHWOSM FUNC=OPEN macro initializes access to the CAVM data sets for a
named generic applid.
Input
The PARM value is a pointer to three further addresses, and these are:
1. The address of the generic applid
2. The address of the ddname of the control data set
3. The address of the ddname of the message data set.
The TOKEN value is the BUILD token.
Output
Register 15
Contains one of the following completion codes:
0 Access initialized, active and alternate signed on
1 Access initialized, active signed on
2 Access initialized, alternate signed on
3 Access initialized, nothing signed on
4 Same SMF MVS name; IPL time of active earlier than MVS IPL
time
5 Same SMF MVS name; IPL time of alternate earlier than MVS
IPL time
6 Insufficient storage
7 Generic applid is not associated with the named CAVM data
sets
8 Access already initialized for this generic applid or for this
ddname
9 Version numbers of the named CAVM data sets do not match
C Data set open failure
10 SHOWCB failure.
A register 15 return code value of ‘0’ through ‘5’ indicates that a DFHWOSM
FUNC=READ macro can now be issued. A return code value of ‘6’ or above
indicates that the OPEN has failed and that the overseer program will not be able to
access the CAVM data sets.
DFHWOSM FUNC=OSCMD macro
The DFHWOSM FUNC=OSCMD macro is used to issue MVS commands. (The
overseer program restarts a failed region in place by issuing this macro.) The text of
label DFHWOSM FUNC=OPEN
