Client noticed that Stored Procedures are not updating immediately after a drop/create. It needs ingstop/ingstart to take effect on all DBMS Severs. Actian this is an old bug, II-7617, a complicated one and Engineering are still checking the feasiblity to resolve. Actian gave a workaround while they are still studying the bug. You can do set trace point qs506 in all DBMS server that might need the DB procedure. This will fkush the QSF cache and forces each DBMS server to rebuild QEP from the DB procedure definition.
