Online DEDB utility region parameters in DCCTL, DBCTL, or DB/DC
There are several positional parameters used by the Fast Path Online DEDB utility in DCCTL, DBCTL, and DB/DC environments.
The procedure FPUTIL uses the first few positional parameters defined for the IMSFP procedure, but interprets several of the parameters as control for the online DEDB utilities. Table 1 shows these parameters.
| FPUTIL Parameter | Generated Value | Purpose |
|---|---|---|
| IFP | IFP | Specifies Fast Path region |
| DBD | N/A | Specifies the DEDB name |
| N/A | DBF#FPU0 | Utility program name |
| REST | 00 | Restart indicator |
| N/A | 00 | No overflow buffers |
| N/A | Null | Default startup, ask operator |
| N/A | 1 | Allows one abend |
| DIRCA | 02 | 2 KB block for PCB |
| PRLD | Null | No preload |
| N/A | 0 | No time limit |
The function performed by the utility depends on the input control statements. A series of DEDB areas can be scanned, have dependent segments deleted, or have the units of work reorganized. If the utility is to be restarted, the REST parameter is coded nonzero.
