Hi,

When I want to generate AWR report for database, I dont see any Snap IDs. What was disabled?

Is it possible to generate awr reports for unseen snap IDs?

Appreciate your help!

Thanks.

It would be helpful if you followed Posting Guidelines - http://www.orafaq.com/forum/t/88153/0/311

NOTE: 436386.1,
"Package for disabling AWR without a Diagnostic Pack license in Oracle"

is "time_statistics" TRUE?

Thanks! This is my first posting, sure to follow it going forward.

Well, Metalink ID looks to be working until 10.2

timed_statistics is set TRUE.

I suspect job not enabled

Enable/Disable automatic snapshots
Note. This job is enabled by default

exec dbms_scheduler.enable('GATHER_STATS_JOB')

and to disable...

exec dbms_scheduler.disable('GATHER_STATS_JOB')

Change the snapshot interval
Note. This example changes it to 15 minutes

exec dbms_workload_repository.modify_snapshot_settings (interval => 15)

Manually take a snapshot

exec dbms_workload_repository.create_snapshot

Okay, Thanks

Desperately needed to see the database reports as we upgrade database to 11gR2. Since, Application team reported slowness.

Thank you for you time

The job likely errored out when it ran out of disk space.

01654, 00000, "unable to extend index %s.%s by %s in tablespace %s"
// *Cause:  Failed to allocate an extent of the required number of blocks for
//          an index segment in the tablespace indicated.

>can you provide me any other options/queries to extend the index.
When tablespace is full only two alternatives exist.
1) add more space to tablespace
2) free up space within tablespace

Since SYSAUX tablespace is owned by Oracle, you are ill advised to manually do DML (DELETE) against it.

It may help to find out what is in your SYSAUX tablespace: query V$SYSAUX_OCCUPANTS to find out. Some of the occupants can be moved to anoter tablespace, the view shows the procedures to do this. You will in any case have to make the tablespace bigger before you upgrade.
Rgds, John.
