VSE/ICCF and Interactive Partition GETVIS Requirements with BIM-EPIC

VSE/ICCF and Interactive Partition GETVIS

Requirements with BIM-EPIC

An ICCF pseudo partition is allocated only 48K of GETVIS and there is currently no way to

change that default. With BIM-EPIC active in the VSE system (it makes no difference if

BIM-EPIC is turned off in the ICCF/CICS partition using OPTION EPICOFF=pp), more than

48K of GETVIS is generally needed just to initiate many programs. The DTSUTIL program

nearly always needs more than 48K of GETVIS and if sufficient GETVIS is not available,

abnormal termination due to various program exception conditions (i.e., addressing, protection

segment-translation, or operation) or BIM-EPIC messages EP042 and EP042A (both referring

to an insufficient GETVIS condition) may result. Invoking DTSUTIL by either of the

following commands entered on the command line will result in the default of 48K of

GETVIS being allocated and will probably result in one of these failures:

$DTSUTIL

/RUN DTSUTIL

In addition, if the DTSUTIL program is invoked from the VSE/Interactive Interface, a

CDLOAD failure could occur. There is no relationship between the amount of GETVIS that

has been allocated to the ICCF/CICS partition itself - this discussion pertains to the pseudo

partitions sub-allocated by ICCF and managed by the ICCF dispatcher.

This problem can be circumvented for the DTSUTIL program by storing a member named

DTSUTIL in the VSE/ICCF library file (preferably in the common library) which contains the

following two lines

/LOAD DTSUTIL

/OPTION GETVIS=256K

(DTSUTIL as a member name is used here only as a convenience - any name acceptable to

ICCF could have been used.) The /LOAD job control statement must always be first. Notice

the /OPTION job control statement which has the GETVIS operand specified. By specifying

a particular GETVIS value, we can temporarily override the default GETVIS allocation of

48K and provide an adequate GETVIS storage for the DTSUTIL program. 256K of GETVIS

is probably too much but a smaller value has not been tested for adequacy.

Once this member has been stored, enter the following command on the command line when it

is desired to run the DTSUTIL program:

/EXEC DTSUTIL

By issuing this command, VSE/ICCF will search for the first library file member name of

DTSUTIL and execute the ICCF job control found in that library member. Now, with

adequate GETVIS storage provided, DTSUTIL will continue processing successfully.
