Description
The length of the user pushdown list, a work area used for Model 204 program flow control
LPDLST also includes some space for the C pattern matcher processing. Complex patterns (for example, patterns involving nested repeated patterns or nested wildcards) might overflow the LPDLST area and require you to increase the LPDLST setting to 32K.
LPDLST can range from 5000 to as large as 32760. Its recommended initial value for SQL processing is the maximum.
You can monitor LPDLST use with the PDL audit trail statistic.
If you get unrecoverable errors when running User Language requests, you might need to increase the size of LPDLST (by approximately 10-20%, depending on your environment and the applications being run) and/or the LQTBL and LSERVPD parameters.
Because checkpointing is asynchronous in 31-bit operating systems, you might need to increase LPDLST in such environments.
