I am running Derby 10.9.1.0 and am trying to figure out a performance problem
with query taking too long. I don't actually want to run the query so from
the documentation, I try:
call syscs_util.syscs_set_runtimestatistics(1);
call syscs_util.syscs_set_xplain_schema('STATS');
call syscs_util.syscs_set_xplain_mode(1);
--- my query here
call syscs_util.syscs_set_runtimestatistics(0);
call syscs_util.syscs_set_xplain_schema('');
call syscs_util.syscs_set_xplain_mode(0);
When it runs my query, I get:
ERROR XCL16: ResultSet not open. Operation 'getMetaData' not permitted. Verify
that autocommit is OFF.
I try the following with IJ just to see:
call syscs_util.syscs_set_runtimestatistics(1);
call syscs_util.syscs_set_xplain_schema('STATS');
call syscs_util.syscs_set_xplain_mode(1);
select sql_text from syscs_diag.transaction_table where status != 'IDLE';
call syscs_util.syscs_set_runtimestatistics(0);
call syscs_util.syscs_set_xplain_schema('');
call syscs_util.syscs_set_xplain_mode(0);
And still get the same error. Could someone try this on their system and see
if it works. It would be most appreciated.
