Adding the TSO Client REXX execs to the SYSEXEC search order

To properly execute TSO Client, you need to add the hlq.version.TSCRX partitioned data set to the search order of the SYSEXEC DD statement in your site's TSO logon procedure.

About this task

When a user starts TSO client, the TSO Client REXX exec, RCCTSOR, attempts to add hlq.version.TSCRX to the SYSEXEC search order. In some circumstances, this SYSEXEC setup operation might fail. To ensure that this requirement is always met, a TSO system programmer can add hlq.version.TSCRX to the SYSEXEC DD statement as part of the TSO user logon procedure. The following is an example snippet of the logon procedure. The DD statement for hlq.version.TSCRX is highlighted:

//TSOUSER EXEC PGM=IKJEFT01,DYNAMNBR=512,REGION=1024K,TIME=1440,
//             PARM='EXEC ''STL.LOCAL.CLIST(DEFAULT)'''
//SYSPROC   DD DSNAME=STL.LOCAL.CLIST,DISP=SHR
//          DD DSNAME=SPF.PRODUCT.CLIST,DISP=SHR
//          DD DSNAME=SPF.PP.CLIST,DISP=SHR
//SYSEXEC   DD DSNAME=xxxxx.TEST.REXX,DISP=SHR
//       DD DSNAME=hlq.version.TSCRX,DISP=SHR
//SYSHELP   DD DSNAME=SYS1.HELP,DISP=SHR
//          DD DSNAME=SYS1.HELP2,DISP=SHR
//          DD DSNAME=SYS1.HELP3,DISP=SHR
//          DD DSNAME=SYS1.PPHELP,DISP=SHR
//ISPPLIB   DD DSN=STL.LOCAL.ISPPLIB,DISP=SHR
//          DD DSN=SPF.PRODUCT.ISPPLIB,DISP=SHR
//          DD DSN=SPF.PP.ISPPLIB,DISP=SHR
