Using the test program
This section describes how to modify the contents of a data space by using a test program provided by BMC.
The test program, called BBD9DSIV, is located in the BBLINK library. The test program creates two separate data spaces, then loads test data and waits. The test program is used in the following exercises to illustrate how to modify the contents of a data space.
To change data-space contents
Copy the test program JCL BBD9DSIV from the BBSAMP library into one of your data sets, as shown in the following figure, and then modify the JCL as instructed in the Instructions section.
//BBD9DSIV JOB (ACCOUNT),'YOUR NAME'
//*********************************************************************
//* *
//* This JOB creates two Data Spaces to verify the MAINVIEW *
//* DSPCZ, DSPCSTAT, DSPCINFO, and DSPCDUMP views. *
//* *
//* Element Data Space #1: Data Space #2: *
//* ---------------------------- --------- -------- *
//* Storage Key REFX 8 0 *
//* Data Space Type TYPX BASIC BASIC *
//* Data Space Name DSPNAME $DSPC001 $DSPC002 *

//* Storage Reference REFX NO NO *
//* Storage Protect PROX YES NO *
//* Current Size CSIZ default* default* *
//* Maximum Size MSIZ 239 524288 *
//* *
//* The Data Space Name is copied to the first 8 bytes of the *
//* space, and the Data Space Stoken is copied to the second 8 *
//* bytes. *
//* *
//* * Default is the installation defined default maximum number *
//* of blocks. *
//* *
//* The program can be terminated by the operator STOP/P command, *
//* or it will timeout after one (1) hour. *
//* *
//* If the program abends, re-submit the job. If the problem *
//* persists, contact BMC Software Customer Support. *

//* ------------ *
//* *
//* Tailor this JCL as follows: *
//* *
//* 1. Replace the JOB card above with one that satisfies your *
//* installation's standards. *
//* *
//* 2. Change '*prefix*' in the //STEPLIB statement to the high *
//* level qualifier you have used for your BBLINK *
//* distribution libraries. *
//* *
//* 3. Submit this job. *
//* *
//* 4. Check the DSPCZ, DSPCSTAT, DSPCINFO, and DSPCDUMP views *
//* under MainView for z/OS *
