9 -- CONSTANTS
10 --
11
12 -- Define constants to control which PL/SQL features are traced. For each
13 -- feature, there are two constants:
14 -- one to trace all occurences of the feature
15 -- one to trace only those occurences in modules compiled debug
16 -- To trace multiple features, simply add the constants.
17 --
18 trace_all_calls constant integer := 1; -- Trace calls/returns
19 trace_enabled_calls constant integer := 2;
20
21 trace_all_exceptions constant integer := 4; -- trace exceptions
22 trace_enabled_exceptions constant integer := 8; -- (and handlers)
23
24 trace_all_sql constant integer := 32; -- trace SQL statements
25 trace_enabled_sql constant integer := 64; -- at PL/SQL level (does
26 -- not invoke SQL trace)
27
28 trace_all_lines constant integer := 128; -- trace each line
29 trace_enabled_lines constant integer := 256;
30
31 -- There are also some constants to allow control of the trace package
32 --
33 trace_stop constant integer := 16384;
34
35 -- Pause/resume allow tracing to be paused and later resumed.
36 --
37 trace_pause constant integer := 4096;
38 trace_resume constant integer := 8192;
39
40 -- Save only the last few records. This allows tracing up to a problem
41 -- area, without filling the database up with masses of irrelevant crud.
42 -- If event 10940 is set, the limit is 1023*(the value of event 10940).
43 -- This can be overridden by the routine limit_plsql_trace
44 --
