Invoking the Image Copy function through DFSRRC00

To invoke the Image Copy function through DFSUDMP0 through the IMS Utility region controller DFSRRC00 to create image copies, complete the following steps.

Procedure

In the DFSRRC00 JCL, code the EXEC statement as follows:
```
// EXEC PGM=DFSRRC00,PARM='ULU,DFSUDMP0,options'
```
The parameters on the PARM statement are the positional parameters. You must code the appropriate parameters on the specific position. Some parameters can be omitted, but each position must be separated by a comma (,).
First position
ULU or UDR
- ULU: Utility region identifier
- UDR: Recovery region identifier
Second position

Program name. You must code DFSUDMP0.

Third position

DBD name. If you use UDR, you must specify the name of the DBD to be processed by the IMS HP Image Copy function. If you use ULU, DBD name can be omitted.

14th position

Y or N. Specifies whether the IMS HPIC Image Copy function uses DBRC.
Code the load module library in the STEPLIB DD statement.

STEPLIB DD statement points to two load module library data sets. These module library data sets must be in the following sequence:
```
//STEPLIB  DD   DISP=SHR,DSN=HPS.SHPSLMD0
//         DD   DISP=SHR,DSN=IMS.SDFSRESL
```
where:

HPS.SHPSLMD0

The name of the library that contains the IMS HP Image Copy load modules.

IMS.SDFSRESL

The name of the library that contains the IMS nucleus and required action modules.

If you want to use the site default table to apply the control statement parameters that you defined in the table, specify the library that contains the site default table in the STEPLIB concatenations.

Important: Ensure that you specify the site default table that is created for IMS compatible JCL jobs. For more information about creating a site default table and setting default values for IMS compatible JCL jobs, see Setting default values (IMS compatible JCL).
When you enable the HASH Check option of IMS HP Image Copy, you must concatenate the following libraries to the STEPLIB DD statement:
- If the HASH Check option is enabled for full-function databases, the load module library of IMS HP Pointer Checker.
- If the HASH Check option is enabled for Fast Path databases, the load module library of IMS HP Fast Path Utilities.
If IMS HP Pointer Checker is called with HOMECHK, CHAINDIST, or COMPFACT option, you must specify the library that contains the randomizer or the segment edit/compression routine.
If STEPLIB is unauthorized because it specifies libraries concatenated to IMS.SDFSRESL, you must include a DFSRESLB DD statement.
Code the appropriate DD statements. For a list of DD statements, see DD statements for the Image Copy function (DFSUDMP0 JCL).
Code the corresponding control statement in the SYSIN data set. For control statements, see Control statements for the Image Copy function (DFSUDMP0 JCL).

Examples are provided in Examples for taking image copies with DFSUDMP0 JCL.
