DBUTIL command in JCL

Syntax:

//stepname PGM=pgmname,PARM=(BMP,DBUTIL,psbname)
//SYSIN      DD *
jobcardstatements

Parameters:

psbname

The PSB name for the IMS database. Because DBUTIL issues DL/I calls like any other application, the PCB must specify appropriate processing options for the calls applied via the control statement file.

DLIcall

A DL/I call to apply to the IMS database specified by psbname.

DBUTILspecialfunction

A DBUTIL special function to apply to the IMS database specified by psbname.

jobcardstatements

These statements include DL/I database calls and/or DBUTIL special functions. Each statement must be formatted as follows:

Columns 1 - 4

Positions one through four contain the DL/I call function or DBUTIL special function. You can specify any supported DL/I database call, such as GHU, REPL, DLET, or ISRT, or you can specify a DBUTIL special function. See DBUTIL special functions for a list of special functions and a description of each.

Column 5

A non-blank character in column 5 indicates the next line is a continuation of this line. This line becomes one of a set of records that is grouped to form one DL/I call. You cannot use this continuation to continue an IO function record.

Columns 6 - 32768

The data associated with the function:

• For DL/I call functions and their continuation records, this is an SSA
• For the IO function, this is the I/O area for ISRT, REPL and DLET calls. Variable length segments must contain the length code as the first two bytes of the data segment.
• For the DBUTIL special functions, this is any data required by the function.

Example Job Card Statements

*Issue get unique call with three SSAs.
*(Note the continuation)
