I have learnt a lot from your blogs. I was looking up the messages file and found it under $ORACLE_HOME/rdbms/mesg instead of $ORACLE_HOME/rdbms/admin Thank you. Harry Hi Tanel,

Excellent post. I have learnt a lot from your blogs.
I was looking up the messages file and found it under
$ORACLE_HOME/rdbms/mesg instead of $ORACLE_HOME/rdbms/admin

Thank you.

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.

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.

Btw in more recent Oracle versions there are more _4031 parameters, all described in that metalink note i mentioned.

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
