bts_tracelevel() function

The bts_tracelevel() function sets the level of tracing. Use this function together with the bts_tracefile() function to trace basic text search-related events.

Syntax


1  bts_tracelevel ( level )
level
The level of tracing output:
1
UDR entry points.
10
UDR entry points and lower-level calls.
20
Trace information and small events.
100
Memory resource tracing (very verbose).

If you enter a value from 1-9, it is treated as level 1, a value between 10 and 19 is treated as level 10, a value between 20 and 99 is treated as level 20. A value greater than or equal to 100 is treated as level 100.

Usage

Use the bts_tracelevel() function to troubleshoot events related to the basic text search extension.

For the syntax for bts_tracefile(), see bts_tracefile() function.

For more details about tracing, see the HCL OneDB™ Guide to SQL: Reference.

Example

The following example specifies a trace file, sets the trace level to 20, and then performs a SELECT statement, which generates a tracing log:
EXECUTE FUNCTION bts_tracefile('/tmp/bts_select.log');
EXECUTE FUNCTION bts_tracelevel(20);
SELECT * FROM vessels WHERE bts_contains(xml_info, 'boatname:black');
The following might be the contents of the tracing log for trace level 20. The number 32 is the trace session number.
