Sys.all SQL statements?

Hello all,

we have a PowerBuilder application (version 12.5) and we have noticed a performance issue. It seems that the following SQL statement is called continuously and it causes severe delays and performance impact:

SELECT SYS.ALL_CONS_COLUMNS.COLUMN_NAME, SYS.ALL_CONSTRAINTS.CONSTRAINT_NAME FROM

SYS.ALL_CONSTRAINTS,SYS.ALL_CONS_COLUMNS WHERE SYS.ALL_CONSTRAINTS.CONSTRAINT_TYPE ='P' AND

SYS.ALL_CONSTRAINTS.TABLE_NAME = 'OLRIVI' AND SYS.ALL_CONSTRAINTS.OWNER = 'XYZ' AND

SYS.ALL_CONSTRAINTS.CONSTRAINT_NAME = SYS.ALL_CONS_COLUMNS.CONSTRAINT_NAME AND

SYS.ALL_CONSTRAINTS.TABLE_NAME = SYS.ALL_CONS_COLUMNS.TABLE_NAME AND SYS.ALL_CONSTRAINTS.OWNER =

SYS.ALL_CONS_COLUMNS.OWNER ORDER BY

SYS.ALL_CONSTRAINTS.CONSTRAINT_NAME,SYS.ALL_CONS_COLUMNS.POSITION

The database versions are 10g and 11g. Any ideas, how to cache, speedup or turn off the statement?


We have tried to change PB.ini options (noCatalog and StaticBind) modifing the file without success.

Thanks in advance,

Mika
