Comment on Using Oracle Wallet to Execute Shell script/cron without hard coded Oracle database password by terkel

terkel — Fri, 18 May 2012 09:57:53 +0000

I still dont get it, so if someone get the ewallet.p12 cwallet.sso files and the connect string (simply by reading/copy them from a Live USB system) he is able to connect to the database?! It seems not very secure to me…

By default window is created with LOW prioirty. If there are two overlapping windows with low and high priority. High priority window takes precedence and it is opened.

Ah, I found it.
Thursday window was 02:00 – 22:00
I changed it on thursday itself at 02:15 (an amusing night…
So I changed the duration while the window was already open… I presume it is not dynamic.
Now (on Friday) the same modification I did on Thursday for Friday window is correctly in place.
Yesterday to solve the problem I had to disable the Thursday window and then re-enable it today

Thanks for your answer anyway.
One more question:
in OEM there is a field name “priority” for a scheduler window.
It defaults to low for the weekday windows (btw: I’m on 11.2.0.3).
I didn’t find precise references to the implications of setting it to high… any pointers?

It’s surprising to have this kind of behavior. Can you check the output of following query and ensure that duration is correctly specified as 90 mins

select WINDOW_NAME,repeat_interval,duration from dba_scheduler_windows

Cheers

Hello,
I previously set maintenance windows (monday, tuesday, ecc..) with start time at 02:00 am and duration of 20 hours.
And I got statistics collected every 4 hours. In fact I saw this in docs:
”
In the case of a very long maintenance window, all automated maintenance tasks except Automatic SQL Tuning Advisor are restarted every four hours. This feature ensures that maintenance tasks are run regularly, regardless of window size.
”

At a certain point I set start time 02:30 am and duration 90 minutes.
So I would expect optimizer statistics only run between 02:30 am and 04:00 am
Instead they continue to run apparently every 4 hours generating problems…
How can I prevent this?

OPERATION START_TIME END_TIME

gather_database_stats(auto) 120419 06:05:47.8204 120419 06:31:04.5265

Is maintenance window setting changes dynamic or do I have to restart anything when changing them?
Thanks in advance,
Gianluca

Comment on Physical Corruption: ORA-1578 -Part 1 by Saurabh Sood

Saurabh Sood — Sun, 15 Apr 2012 05:44:37 +0000

You can use rman blockrecover command, if the number of blocks corrupted are large in number then you can consider doing closed DB recovery using restore system tablespace and recovering it.

Thanks.

I have gone through http://askdba.org/weblog/2010/09/renaming-diskgroup-containing-voting-disk-ocr/ link. But the diskgroup I was trying to rename is not used to store OCR/Votedisk. But the DATABASE_COMPATIBILITY is shown as 10.1.0.0.0. Is this the main culprit for above error?

Thanks,

Hi Amit,
It’s very useful post indeed.

I am planning to rename an ASM Diskgroup in a clustered environment with only one node now.

Do I still need to disbale has (crsctl disable has) before starting the task?

Thanks,
Praveen Rao K.
