java - Maximum open cursors exceeded - with hibernate SchemaValidator -


our oracle 11g database contains 298 tables(10 added), (+100 sequences), declared 500 cursors.

when starting our webapplication (tomcat 7.0, jdbc pool), @ sessionfactory initialization when hibernate validates schema uses cursors (cf below).

is there known in order hibernate less greedy oracle cursors ?

please note problem has nothing handling of prepared statements or hibernate entities not work of them @ step.

if driver version 12.1.0.2 known bug:

https://community.oracle.com/thread/3682300

in nutshell: databasemetadata.gettabletypes() creates statement never closes it, leaves cursor open.

most hibernate calls gettabletypes() quite during schema validation , affected bug.

the driver version 12.1.0.1 not affected this, might want downgrade.

this logged under bug #19632480 if have access mos can download patch this.
