Well at least not with the pre-11g event syntax. Maybe with new 11g debug infrastructure it is possible, but I don't have access to the internal document describing the syntax. The examples (lifetime and after x times) I showed, are more useful in cases where you want to apply some action to certain error like deadlock or ORA-4030 etc. Not that I know of.

Like i want to enabled 10046 for next minute. Hi Tanel, is it possible to enable the trace based on time limit?
Like i want to enabled 10046 for next minute.

From 9.2 onwards you can use _4031_dump_bitvec parameter to control level and frequency of heapdumps on 4031 errors. Read metalink note 396940.1 for details. One other option is to set _4031_dump_bitvec = 0 to disable the built in heapdumps and use an event '4031 trace name heapdump level x, lifetime y' Btw in more recent Oracle versions there are more _4031 parameters, all described in that metalink note i mentioned. <pre><code> SQL> @pd 4031 NAME VALUE DESCRIPTION --------------------------------------------- ------------------------------ ---------------------------------------------------- _4031_dump_bitvec 67194879 bitvec to specify dumps prior to 4031 error _4031_max_dumps 100 Maximum number of 4031 dumps for this process _4031_dump_interval 300 Dump 4031 error once for each n-second interval _4031_sga_dump_interval 3600 Dump 4031 SGA heapdump error once for each n-second interval _4031_sga_max_dumps 10 Maximum number of SGA heapdumps </pre></code> Hi Martin,

Can I use "lifetime 10" in "alter system set events"? Best regards, Martin Hi Tanel,

what would be your approach in getting heap dumps for ORA-4031 without filling the disk in case dozens of ORA-4031 appear at once.

Can I use “lifetime 10″ in “alter system set events”?

Best regards,
Martin
