Step 1—Modify default parameters (optional)

If desired, modify the default parameters for operating the tableBASE software in an IMS message processing region (MPR). If the default values are acceptable or you wish to use the Override feature provided via the TBOPT dataset, no additional work is necessary in this step.

For parameter descriptions, see tableBASE run-time options. The default values for this component are listed below and are also defined in your.prefix.SRC(DK1T1334).

Default IMS parameters

TBOPTGEN IMS,
            ALLOW_TB_LIB_IO=Y,
            DATERTNX=N,
            FGDELIM=*,
            HASH_HI_DEN_LIM=900,
            HASH_LOW_DEN_LIM=600,
            LISTOPTIONS=N,
            LOCKTIMERC=0,
            LOCKTIMEWTO=30,
            MAXNMTAB=0,
            MTRETAIN=N,
            OVRRIDES=YYYYYYYY,
            RACF_LIBACCESS=N,
            STROBE=0,
            SWITCHES=NNYYNNNN,
            TABLEWAITRC=0,
            TABLEWAITWTO=30,
            TSR_ALGORITHM=D,
            TSR_WARNING_FREQ=1,
            TSR_WARNING_PCT=85,
            TSRSIZE=10M,
            USEREXITS=N,
            VTSFIRST=,
            VTSLAST=,
            VTSNAME=,
            VTSPREFIX=VTS:, 
            ZEROROWS=Y,
            ML=MAINLIB

To make changes to the installation parameters:

• Modify your.prefix.SRC(DK1T1334).
• Reassemble and link-edit the module into the tableBASE IMS interface program DK1IBASE using your.prefix.CNTL(ALT1334) as a model.
