> Analysis of the trace files for the bind-variable version reveals that the
CPU time to EXEC the anonymous block (and, to a lesser extent, its constituent INSERT statements) steadily increases. The first time through the CPU time is about 0.02 second. By the last execution before the timeout, the CPU time is just about 1.0 second. Interestingly, the logical I/O stats for each execution are quite low (<100 current reads and consistent reads) and quite consistent.
Are those timings for a serial execution of the block by the same connection, or by concurrent execution by different connections ? Is the block identical for bind variables names also ? ie begin insert ... values (:bind_one); insert ... values (:bind_one); end; or begin insert ... values (:bind_one); insert ... values (:bind_TWO); end; -- Alberto Dell'Era "dulce bellum inexpertis" -- //www.freelists.org/webpage/oracle-l
