Database hang issue

Hi,
My report database(standby database) sometimes getting hang,
also that another db,lets say testdb also accessing my standby db via dblink.
there was no constant time to say that my report db getting slow.
AMM(automatic memory management) has been enabled in my environment.
so what are all the possible rootcause to overcome this?
Help me regarding this.
Regards,
mafaiz

dbversion:Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
osversion:RHEL
alert log file has not much useful during the time.
What are all other possible areas to check\ensure?

Shutting down database hangs

Dear Gurus,
I m facing a database hang issue while performing the scheduled offline backup.I m able to take the online backup.When the backup starts , the database starts to shutdown.When checked in the log of backup it shows in tail as shutting down database.When checked for user trace , it shows message as "Attempting to kill pid xxxxxxx" and keeps on retrying for n no. of times.Then I have to manually kill the backup and restart the application.Then again try for an offline backup.This time it happens smoothly.This activity we did for couple of weeks .But now from past 3 days even after restarting the backup, it goes to hang mode.In other words unable to perform the backup activity.
The message had been raised to SAP from almost 15 days at very high.They every time ask the logs , and say that the data in log is nt providing much info for analysing the issue or cause of hang.Also enabled the traces of 10400 for trace level 1 ,10 some more traces also.But still the output is not helping even them to analyse the root cause.
Its my observation that this issue is occuring only on ABAP+JAVA systems(CRM &BIW)not in ECC.We are on oracle database 10.2.0.0.4 with latest patch set as suggested by SAP for the same issue.
This issue is h
Please suggest me at the earliest.As need to resolve this at the earliest.
Bye.

Note: From 11.2.0.2 onwards, hanganalyze will not produce output under a sqlplus "preliminary connection" since it requires a process state object and a session state object. If a hanganalyze is attempted, the trace will output:

Is something i am missing or there is some different steps.

This many not be a case of process hang. So check with LEVEL 10 .
Still if you are getting the same error than , you need to contact oracle support.

CF Builder2 hanging issues

We recently started installing CF Builder2 on developer machines, and almost all of them are reporting serious hanging issues with the computers locking up.
Has anyone experinced/experiencing this problem?

Yes, @umuayo, there can be many explanations for CFB hanging. I discuss a few here, but more than just pot-shot guesses, I also offer some specific diagnostic steps you can take to hopefully find and resolve such problems.
One common cause I recall hearing is when you have your CFB project set to look at files on a share (rather than on a local drive to CFB).
Consider that CFB is doing a lot more than just “editing a file”. It’s doing syntax checking on the fly, it’s looking up methods in CFCs, files you can include, tables and columns in databases as you type SQL, and all manner of other helpful operations…all of which can be expensive for it to figure out depending on your configuration.
There are also some operations that are done either on startup, or on certain other operations you may do only once in a while.
So when you say it hangs up, when does it do so? At startup? After some period of time? On doing some particular operation? And of those may help you narrow down the cause.
One helpful tip is to open the Progress View in CFBuilder (Window > Show View > Other ). That shows background tasks that are run when you do various things within builder, especially communications going on back and forth between CFB and any server you may have it talking to. If you have that view open all the time (best viewed at the bottom of the window to be wide), you may see what it was starting to do when things hung up.
Still another common problem is that people find that the problem is that the JVM (within CFBuilder) is running out of heap. Just as CF can hang and crash when that happens, so too can CFB (independent of CF, of course.) You can tweak the max heap size (xmx argument) in the startup properties for CFB. If you’re using the standalone edition (versus running CFB as a plugin), you’d tweak the cfbuilder.ini file in the directory where CFBuilder is installed. If you’re running as a plugin, I’d recommend you research how to change the JVM args based on your OS, version of Eclipse, how you start it, etc.
Also related to memory, you can also set CFB (and Eclipse) to show you a heap size use indicator (and even request a GC), with the feature that appears at the bottom of the editor window when you go to Preferences>General then click Show heap status.
Similar to the above, but different, another thing people have found is a problem on 64-bit Windows, which is resolved with another simple change in the startup args (changing it from using javaw.exe to using jvm.dll for the jvm). For more on that, see these two blogs: http://www.websolete.com/posts/cfbuilder-2-performance-problems-on-windows-7-64-bit-solved and http://www.coldfusionmuse.com/index.cfm/2012/1/27/cfbuilder-performance-64bit-plugin.
Finally, and perhaps the easiest thing to consider: you mention being on “CFBuilder 2”. You don’t clarify if that’s really 2.0 or 2.0.1, the free update that came out at the same time as CF10. That has various performance fixes, listed in a section at <http://www.adobe.com/devnet/coldfusion/articles/cfbuilder201-whatsnew.html> http://www.adobe.com/devnet/coldfusion/articles/cfbuilder201-whatsnew.html, including a mention of some features that can have a performance impact that you may want to watch out for.
Also, if you are still on CFB 2.0 and choose to remain there for some reason, there was a hotfix for that, <http://www.adobe.com/support/coldfusion/downloads_updates.html#cfb2> http://www.adobe.com/support/coldfusion/downloads_updates.html#cfb2.
Hope that helps. Let me know what you think.
/charlie
PS there are a few blog entries out that address CFBuilder performance. If for some reason the above don’t help, consider these as well, though do note that some could be from the CFB1 or CFB2.0 era and may not be as relevant for CFB2.0.1:

Cisco NAC server hang issue

Hi All Cisco NAC Experts, I am currently experiencing a Cisco NAC NAC3315-SVR hang issue.
The issue was already happened for few time on the same server and the symptom when NAC server hung includes no response to ICMP ping, no response to SSH request, no response for access request to CAS management page via https, HA pair was detected down from its HA neighbor and triggered failover to secondary CAS.
The CAS server was recovered after manually power cycle the hardware.
After went through the attachment CAS logs, I found all the services and logging service were stopped when the issue happening but unfortunately there is no any suspicious activity was logged down before or during the issue happening.
I have also tried to search on Cisco Bug Toolkit but no similar case was found, I believe it was not caused by software bug due to the software version 4.8.1 is running in my company for years and only one CAS server having the issue.
That will be great if any one can help me out for the same.
Thanks,
Eric

Hi Bro
This could be a problem with the certificate in that Cisco NAC appliance itself. My suggestion is to redo the certificate generation between the CAS CAM and CA Server. If this still doesn’t work, it could also be due to overload/broadcast storm on the LAN portion. This can be verified via Wireshark.
If all else fail, then a hardware swap would seem like the next best thing.

Oracle 10g Database Hanging twice a day

My database server has 10g with MS 2003 server as OS.
Twice a day the database hangs and does disconnects all the users from local and remote locations.
Current SYSTEM tablespace has a size of 470 MB and is 98.86 in use, when I try to add another datafile as 'SYSTEM02.DBF' in the same path where other system data files are, I kept this operation running during weekends but datafile was not added.
Has it anything to do with the MS 2003 server no. of users.
Any other suggestions for SYSTEM Tablespace to be free.
Please reply.
Thanks

Database performance issue (8.1.7.0)

Hi,
We are having tablespace "payin" in our database (8.1.7.0) .
This tablespace is the main Tablespace of our database which is dictionary managed and heavily accessed by the user SQL statements.
Now we are facing the database performance issue during the peak time (i.e. at the month end) when no. of users use to run the no. of large reports.
We have also increased the SGA sufficiently on the basis of RAM size.
This tablespace is heavily accessed for the reports.
Now my question is,
Is this performance issue is because the tablespace is "dictionary managed" instead of locally managed ?
because when i monitor the different sessions through OEM, the no. of hard parses is more for the connected users.
Actually the hard parses should be less.
In oracle 8.1.7.0 Can we convert dictionary managed tablespace to locally managed tablespace ?
by doing so will the problem will get somewhat resolve ? will it reduce the overhead on the dictionary tables and on the shared memory ?
If yes then how what is procedure to convert the tablespace from dictionary to locally managed ?
With Regards

If your end users are just running reports against this tablespace, I don't think that the tablespace management (LM/DM) matters here. You should be concerned more about the TEMP tablespace (for heavy sort operations) and your shared pool size (as you have seen hard parses go up).
As already stated, get statspack running and also try tracing user sessions with wait events. Might give you more clues.

Oracle 8i database hangs for the same amount during JDBC calls.

Hi all,
I have a Oracle 8i database on solaris. The database hangs for exactly 61 seconds for a random jdbc call from my Java application, i mean there is no particular pattern or a JDBC call for which the database hangs. If i choose to wait for 61 seconds it returns the results from the database but if i try to access the database with another query(SQL Plus) the first query starts executing immediately. Is that a database configuration problem or some thing else.
And i also get some exceptions occasionally( Maximum Open Cursors exception). Are these two related?
Any feedback is appreciated.
Thanks
Hugo Victor

I have uninstalled Oracle 8i.
Removed all the services from Windows services by deleting corresponding registry entries and deleted the Oracle folder.
I have reinstalled Oracle 8i, this time i changed the name of global database to oracledb.
I channged the tnsnames.ora file from DevSuite appropriately as:
# tnsnames.ora Network Configuration File: C:\DevSuiteHome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = mscserver)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = ORACLEDB)
Still it can't login using scott/tiger authentication.
What may be the problem? Please help.

Nokia 301 RM-839 v9.04 hanging issue.

Hello,
I have observed hanging issue while we take photo using camera. Instead of saving & showing options it show image taken preview. Keyboard also hangs. Only way is to stop camera or restart removing battery.
Has anyone seen such issue? Any clue?
Kindly Suggest.
Thanks,

occasionally phones can receive "updates", where the actual SW version remains the same. Usually this means just some very minor tweaks to e.g. operator settings or similar things. So hardly anything noticeable.

What to do when database hang

Hi all,
May I know what to do when database hangs after shutdown immediate command perform? Can I use kill process command to stop Oracle process?

Hello,
see documentation for details of immediate-clause:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/start.htm#sthref589
You can do an shutdown abort instead, but then sql is terminated. You can read details here: http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/start.htm#sthref595
