01-04 | EXEC and STEPLIB DD statements for Fast Path/EP offline execution. |
05 | IMSACB DD statement used for database processing. |
06-08 | Area data set names. |
09 | PFPSYSIN DD for Fast Path/EP control statements. |
10 | Analysis is performed for all areas (IAREA=ALL is default). Full (cross-reference) pointer validation is performed on all areas in the DEDB. |
11 | The THRESHOLD subcommand and the keywords that follow it help to determine whether there are any potential problems due to free space limitations. |
12 | If the analysis process detects less than 10% of free space available in DOVF in the area, a warning message is issued. |
13 | If the analysis process detects less than 15% of free space available in IOVF in the area, a warning message is issued. |
14 | If the analysis process detects less than 20% of free space available in RAA in the area, a warning message is issued. |
15 | If the analysis process detects that the percentage of RAP blocks that overflow into DOVF/IOVF exceeds 15%, a warning message is issued. |
