Hi Friends,
We can define multiple savepoints within a trasaction.
Can we get the information about the savepoints defined in current transaction?
Regards,
Dipali...

Hi Michel,
After declaring multiple savepoints within transaction, we can committ or rollback transaction upto any of those savepoints. Means, oracle is keeping track/information about those savepoints. Then as a DBA, can we not have the information about those savepoints?
Suppose the case is: Some developer has declared multiple savepoints in his trasaction, and he lost the track, which savepoint name he/she had given, and he asks for the help to us, can't we have track of the savepoints declared by him?
Regards,
Dipali..

The fact that Oracle knows it does not mean it wants us to know it.
This information is not exposed to the user.
By the way, how can a developer lose which savepoint he gives? He just have to look at his code.

Michel

Michel,
How can i dump that internal savepoint structure?
I read that oracle stores this savepoint information in some internal tables. Can't we get that table information or that table data anyhow..?
Thanks and Regards,
Dipali..

hello michel,
I tried that statement on oracle 10g's database' scott schema.
From net, i found that, the information will be recorded in the trace file in user dump directory.
After that, i open new session of "SCOTT" user, created 3 savepoints, and after each savepoints executed some dml statements.
I got the trace file name for this session using following script.
1 select
2 u_dump.value || '/' ||
3 db_name.value || '_ora_' ||
4 v$process.spid ||
5 nvl2(v$process.traceid, '_' || v$process.traceid, null )
6 || '.trc' "Trace File"
7 from
8 v$parameter u_dump
9 cross join v$parameter db_name
10 cross join v$process
11 join v$session
12 on v$process.addr = v$session.paddr
13 where
14 u_dump.name = 'user_dump_dest' and
15 db_name.name = 'db_name' and
16* v$session.audsid=1606078
17:47:05 SQL> /
Trace File
---------------------------------------------------------------------------
/oracle/admin/stag/udump/stag_ora_9684.trc
Elapsed: 00:00:00.07
17:47:11 SQL>
But this trace file was last updated before nearly 45 minutes. I am monitoring this file content right before executing "alter session " statement till now. But it isn't updated yet. So i couldn't get savepoint information.
My question is: when oracle will create/update trace files (in user dump and in background dump folder)?
Thanks and regards,
Dipali..
