Analyzing a disabled wait

A disabled wait condition can be analyzed by checking the PSW at the time of the error. If bits 6 and 7 are zero and bit 14 contains a 1, there is a disabled wait. The wait state code is in byte 7, with the reason code in byte 5.

The following examples show how to determine the wait state code:

In the following PSW, the wait state code is X'014' and the reason code is zero.
```
  PSW=000E0000  00000014
```
In another example, the wait state code is X'064' and the reason code is X'09'.
```
  PSW=000A0000  00090064
```
In z/Architecture® mode, the PSW would look like:
```
  PSW=0002000 00000000 00000000 00090064
```

After you determine the wait state code from the PSW, look at the documentation for the specific wait state code for any action you can take. See z/OS MVS System Codes for the specific wait state code you encountered.

If you cannot find the wait state code documented, do one of the following:

Analyze the dump to determine if it is a stand-alone dump wait state.
Check PSASMPSW and PSAPSWSV to determine if the dispatcher loaded the wait state PSW because of an overlay. See The dump grab bag for more information about storage overlays.
Use the stored status registers to determine who loaded the wait state into the PSW.
