Why trace files are generated for CDC activities ?
Hi,
We have CDC implemented in our database for DW. But I can see that good amount of trace files are generated which are related to CDC activities.
Why these files are generated ? Is there any way to stop it ?
I am pasting contents of one of those trace files.

Hi davey23uk,
Thanks for the reply. But the value of sql_trace is false. I have not found any info regarding this in metalink site. Can you suggest what is the possible reason ?

Hi davey23uk,
I have found that there is one account of cdc user and that user issues command "ALTER SESSION SET EVENTS '22825 TRACE NAME CONTEXT FOREVER, LEVEL 1'".
Can anyone tell what is purpose of using this event ? Is this event generates the trace file ? what does it do on level 1 ? Is it good
for issuing this staement everry day ?
