Description
This numeric parameter indicates the maximum number of CCATEMP pages that will be allocated for a user for holding trace data. The CCATEMP wrap-around trace table is a user-specific trace table that consists of a set of CCATEMP pages whose maximum size is specified by the ULTRACEP user parameter.
If ULTRACEP pages are already in use when a Trace statement is issued,
and output is being routed to the trace table (ULTRACE X'04' set —
see ULTRACE), the trace data on the oldest page is discarded, and the oldest page is reused for the new trace data.
The wrap-around trace table is dumped in SirFact dumps, and it can be viewed with the following command when using the FACT subsystem to examine a dump:
D[ISPLAY] T[RACE][.{* | N}]
where N specifies that the last n entries are to be displayed.
Specifying D T will display all trace entries,
and specifying D T.20 will display the last 20.
The current contents of the wrap-around trace table can also be examined with the $Trace2List function or the Stringlist class AppendTrace method.
