Thanks,

First Thing First........
I generally never take any such step until it become essential. I always use the above command to kill LOCAL sessions and DB comes down in sometime.Oracle is ORACLE. There are some magical things happen. Something work somewhere and somewhere not.
1. The only thing you can check is ALTER_ORACLE_SID.log.. There you come to know what is happening. Along with this you can see whether the number of orcle processes are coming down. If Not then something needs to be done.
2. Don't use such thing which is not adviseable. This is wried. You can never know when a problem will be in front of you.
KILL THE LOCAL SESSION AND ORACLE WILL DOWN IN 99.9% CASES.
Let me know if someone disagree with me.

Shutdown immediate hanging

I need to develop a scripts that shuts down all databases on a server. One of my databases sometimes hangs after issuing "shutdown immediate" command, and I want to handle this situation in my script. What I am thinking is to add "shutdown abort" in the script if "shutdown immediate" does not work. However, I do not know how to determine the database is hanging during shutdown immediate. Can you advise me on how to handle the shutdown immediate hanging problem in my shell script? Or is there better way to handle this in the script?
Thank you very much for your help!

As noted, if your shutdown immediate really hang because of rollback, then my method won't work either. The only different will be Oracle is going to do the rollback at next startup when doing instance recovery. In that case, the startup will appear to be hang.
Check this metalink doc,
What To Do and Not To Do When 'shutdown immediate' Hangs
Doc ID: Note:375935.1
There are cases where shutdown immediate hang because of bug.

If shutdown immediate hangs database waits one hour for shutdown abort

we have schedules cold backup for our 11g database on redhat 5.3.
there is a shell script written with shutdown immediate command.
If database hangs during shutdown immediate database waits one hour for auto shutdown abort.
but this happens once or twice in a month
can we do this auto shutdown abort earlier than one hour ??

Since you're shutting down the database for cold backup so ensure it should be shutdown properly by shutdown or shutdown immediate cmd not by abort cmd.
Consistent backup:-
A backup taken when the database is mounted (but not open) after a normal shutdown. The checkpoint SCNs in the datafile headers match the header information in the control file. None of the datafiles has changes beyond its checkpoint. Consistent backups can be restored without recovery.

Customer shutdown database every night for backup the datafiles to disk.
For your information, 2 weeks ago customer moved datafiles to a new disk.
The stoppscript has worked for a week.
And after a week the database will not shutdown.
We did a shutdown abort, and it works for a couple of days.
Now it happend again. The database will not go down.

Shutting down instance (abort)

I am having similar problem. My server has been up for around 100 days now. And I extensively use XML DB in my code. So, now the DOM memory failed for me, so, I am doing shutdown immediate in the hope that it might fix it ( or atleast start where it is hanging).
Here is a snippet of my alert log file. Can you see where I am stuck at?

Shutdown immediate hangs and HVM of a database

Hi,
I have following questions,
1. What are the possible causes of SHUTDOWN IMMEDIATE command hangs
and doesnt responds.
2. What do u mean by High Water Mark(HVM) of a database. Because when we
give SHUTDOWN IMMEDIATE command there is message in alert log file
mentioning the HVM of a database.
3.Also is there any relationship between shutdown process taking long time to
shutdown a database and HVM of a database.
4. If the database instance is up for a long time then does it take long time to
shutdown a instance.
Thanks,
Girish A

Hello,
for 1.) view Metalink Note:375935.1. Maybe you even get an error: "SHUTDOWN: Waiting for active calls to complete". This has nothing to do with HWM but with already logged on sessions. Immediate means new connections are not able to log in, existing connetions are not disconnected at once.
for 2.) the HWM is the highest point to which datafiles have been filled up. This is the value to which you are able to shrink (if you desire to). View Metalink Note:1034330.6 for message "License high water mark" in alert.log at shutdown ("highest number of concurrent users sessions").

Hello Jonathan Lewis,
1-Please note that looking into the alert_sid.log is a good start as it will show if the smon process was dead according to the note:
Shutdown Normal or Shutdown Immediate Hangs. SMON disabling TX Recovery [ID 1076161.6]
I can see that that note is labelled: "Checked for relevance June 2009", but have you seen the garbage it suggests for temporary segments:
<ul>
Verify that temporary segments are decreasing
To verify that the temporary segments are decreasing have an active session
available in Server Manager or SQLPLUS during the SHUTDOWN IMMEDIATE. Issue the following
query to ensure the database is not hanging, but is actually perform extent
cleanup:
SVRMGR/SQL> select count(block#) from fet$;
COUNT(BLOC
+7+
SVRMGR/SQL> select count(block#) from uet$;
COUNT(BLOC
+402+
</ul>
For this to be true the temporary tablespace would have to be declared as dictionary managed, possibly even with contents = "PERMANENT" but it's so long since I've created a dictionary-managed TEMP that I can't be sure of the second point. I would be very cautious about trusting any document that started with such antiquated material - you can have no idea how much of its content might be (at best) deficient and (at worst) dangerously wrong.
3-to know the transactions that will be rolled back please read the note:
How to Check Why Shutdown Immediate Hangs? [ID 164504.1]
Same type of problem - "Checked for relevance: Mar 2010", starts with:
<ul>
Start Server Manager (or SQL*Plus for 8i or higher)
SVRMGRL> connect internal (or SYSDBA for 8i or higher)
SVRMGRL> select * from x$ktuxe where ktuxecfl = 'DEAD';
</ul>
Although x$ktuxe will show you transaction states from the undo segment headers, and this might show you recursive (or other special case) transactions that do not appear in v$transaction, I wouldn't trust a note that is based on 7.3 technology to be an appropriate reference document.

Shutdown immediate problem

I'm trying to shutdown an Oracle9i database on Unix using SHUTDOWN IMMEDIATE but it just hangs.
I checked the sessions in V$SESSION and noticed there were a few INACTIVE sessions. So I built a script that goes thru all the INACTIVE sessions and kills them.
With all these sessions having status KILLED...when I try to run a SHUTDOWN IMMEDIATE, the database still hangs. I don't want to use SHUTDOWN ABORT.
Does anyone have any information on what makes SHUTDOWN IMMEDIATE hang? Could there be some unix processes....or oracle processes?
Thanks

Dear All,
I am also having some shutdown problem with the Oracle 10g on my Windows Server 2003 machine. My machine could not shutdown (means OS cannot completely shutdown the machine) even after i issued the "shutdown immediate" command.
As what Jaafar said, we should kill the process from OS level. Can any of you explain more on this as I have no idea on how to do this? Which process should I kill after I issued the "Shutdown immediate" command?
Thank you.
best regards,
Wnson

Application hangs for every 20-30 mins

Hi All,
We have typical (just forms and reports) HTMLDB application which has been developed in version 1.6.0.00.87 and hosted on same version. But the users are facing a weird issue which is interim and occurs randomly. The system just hangs for every 20-30 min. Users have to close the browser and have to run the application again to work with. It may hang at any point of time, when user clicks on 'List pop-up' or 'date pop-up' or anything.
I am confused where to start the investigation for this issue. I appreciate any help on this.
Many Thanks

Hi Hari,
It sounds like you need to do more diagnosing of the issue.
Tools that can help you in your analysis:
(1) do a trace of a slow session (see the Oracle docs for how to do this)
(2) set the apex debug on for a slow session then examine the output looking at the slow point
(3) if the first two don't help in the diagnosis of the issue try running the page through Firefox using the YSlow add-in

Com.apple.launchd DumpPanic - System hangs for 5 mins on boot

We've been having a problem with one of our Mac Pro's for a while now.
It hangs for about 5 mins on boot - slowly gets past grey screen and hangs on blue screen.
The Mac is a 2.66 Quad-Core Intel.
The problems began a while back, when running photoshop - the scratch disk filled the hard disk entirely on a really large document and the whole system died. On reboot the system started to hang in the boot process and has done ever since.
The system also appears to be sluggish and doesn't respond as well as an identical machine next to it.
I checked the boot log and noticed a few issues, some of which i've now fixed - ie a faulty USB device causing some problems.
This is what i've got now:
28/04/2011 12:41:53 com.apple.launchctl.System[2] launchctl: Please convert the following to launchd: /etc/mach_init.d/dashboardadvisoryd.plist

What i've tried:
Repair Disk Permissions - using disk utility and disk warrior.
Cleaned cache and settings using Maintenance and Onyx.
Turned off automatic time/date setting from server.
I then backed up and reinstalled the OS.
The OS is now on a separate 160GB SATA drive, with the previous 500GB SATA system drive as data storage.
I have installed back to 10.5.8 and still get this problem.
It seems to me that there is a delay of about 5 minutes after this line:
com.apple.launchd[1] (com.apple.DumpPanic[29]) Exited with exit code: 1
However after LOTS of googling and scouring forums i can't seem to find a definitive answer as to why this problem exists.
Can anyone help me?
My next step is to book an appointment with a Genius, but thought i'd ask on here first.
Another strange conundrum is that if i try to upgrade to Snow Leopard, i insert the disc - open up the installer - click restart and the system restarts, but nothing gets installed.
Thanks in advance for any support you can provide.
Cheers,
Rob

I took this machine into the Genius bar yesterday and they managed to fix it after about 45 minutes of tinkering.
The error i've detailed above is a kernel error, caused by something not loading properly as the system boots.
First of all it took ages to boot to the installed Leopard, so they tried booting to an external drive with a clean install, but that was no quicker.
They ran hardware analysis and everything seemed fine.
The fix was to clone snow leopard across from a pre-installed clean version on an external drive, onto the internal HDD and that did the trick - its back up and running and is quick as ever before.
Thanks Genii

When trying to export to Excel the tool hangs for 10-15 min. (1.5.1.54.40)

When trying to export a result set after a query the tool hangs for 10-15 minutes. This is regardless of the export fileformat; xls, html etc. It seems like the problem is related to the complexity of the query: Low-cost query=export OK, High-cost query=Export Not OK (even though the number of returned records is low)
Exporting to any fileformat from a tables data-tab is OK, the problem occurs only in combination with a query that has been ran in a Worksheet.
Will be greatful for any hint!

If you are using SQL Dev 1.5.1, you can include the column header by using

Hi,
Just wait and see for some time, since usually it might take time to rollback the things of the uncommitted transactions, just from the pstack with process id what might have carried out @stack on system level or OS level.
other wise oradebug the process stack we can able to trace out the things.

Shutdown immediate - will be a problem?

I need to shutdown Oracle database. I wonder if I can do it cleanly? The problem depends on that there is a session 497 which can't be killed neither on database level nor os level. (On database level it simultanously expires and starts with new serial, on os level there is no process related to this session, or it can be zombie process we have, which can't be killed too) Session 497 is probably related to badly canceled operation of bringing a datafile online. Sometime ago we had to bring a datafile online so media recovery of this datafile was required. As we had no archivelog (21 days window) the media recovery couldn't be acomplished. This operation hung. Session 497 may still want to recover that datafile. How do you think? May any problems occur during a shutdown process? May shutdown immediate process wait (and hang too) untill the 497 session end?

Shutdown immediate taking time

HI
I m using oracle 10g release 2. on hpux itanium
some of my database is taking longer time to shutdown more than 30 minutes. so usually i m doing
startup force and than shutdown immediate... wat is the problem behind this and how can i resolve it plz suggest.

A SHUTDOWN NORMAL will wait for sessions to disconnect. So, if you have application processes or users that do not disconnect, it will "hang". It is likely that this is causing your shutdown to delay. You could check the alert log file for messages about Oracle waiting for users to disconnect.
A SHUTDOWN IMMEDIATE will kill active sessions, complete a rollback of transactions that are killed and then shutdown the database. If you are using a SHUTDOWN IMMEDIATE, this can take a long time if there are large active transactions (or many active transactions) that Oracle needs to rollback -- the rollback can take time. (Also, if there are very many connected sessions, Oracle will take time to disconnect all of them).
A SHUTDOWN ABORT does a quick kill by shutting down the instance, without validating connected sessions. Rollback is automatically initiated by Oracle with the Instance Recovery at the STARTUP. The STARTUP can take slightly longer (in terms of seconds or a few minutes, generally) depending on the volume of Redo to be re-applied. Rollback is deferred to be executed after the OPEN.
You could try a SHUTDOWN TRANSACTIONAL. However, this can still take a long time or "hang" if a user or application process (or multiple of them) has/have active transaction(s) and does/do not issue COMMITs.
See the documentation on the SHUTDOWN command :

What to look for in UPS for Mini?

I'm looking for a modestly-priced UPS which can protect a Mini even if no one is present to shut down the Mini manually.
I'm not clear about how usb communication between the UPS and the Mini is supposed to work:
Does it signal the Mini to go to sleep, and then when the UPS finally cuts the power, the Mini is OK because the pre-shutoff state is safely saved in the "sleep file"?
Or does it require special software on the Mini that actually issues a shutdown command to the Mini? (This would seem prone to failure, since shutdown commands sometimes fail if processes aren't willing to terminated.)
Even though I always have used UPSes, I've never had them automatically turn off or sleep my computers, so I could use some education in this area. The UPS is for a computer novice who would not be able to manually shut off the Mini in time. The user's Mini is Core2Duo, Leopard 10.5.6.

Check out the APC ES line of UPS. The USB connection allows the Mac mini to monitor the connection between it and the APC UPS. In the Energy Saver Preferences you'll have several options to configure your mini to handle shutdowns using the Shutdown Options button - based on time of battery usage, remaining time of UPS battery and percentage of UPS battery. You don't even have to load the Powerchute software that is provided if you prefer not to use it.

Shutdown immediate hangs for 30 mins
