The app was getting an ORA-600, which metalink identified as a 'bug' in 9i. The app uses persistent connections and the 'login' package had been recompiled without removing the connections. All of a sudden the ORA-600s started being thrown.
It made me curious (call me George) as to how Oracle handles code consistency in procedures. The scenario I pondered was that a proc is called within a loop. At some point while the loop is being executed by a calling app, the proc is changed. This could cause the app to alter the handling of the data and produce inconsistent results. Since the proc's execution is complete, is the proc still pinned? Just trying to understand a little more about oracle internals... -----Original Message----- Sent: Thursday, September 26, 2002 4:58 AM To: Multiple recipients of list ORACLE-L What is the error and how is the error occuring? My experience has been: 1. Long running SQL calling PL/SQL function: will die due to invalidated state of the function. 2. Long running PL/SQL calling PL/SQL procedure (statically): cannot re-compile the procedure during the run as it is pinned. 3. Long running PL/SQL calling PL/SQL procedure (dynamically): will just run whatever procedure exists at the time of the call. - Bill.
