Performace problem in oracle DB after Solaris 10 recommended patching

Dear All,
We are facing some performance problems in our oracle DB qerries and reports recently. We applied Solaris 10 recommended patchset on april 24th. Our monthly report generation acitivity is now running for last 3 days i.e may 11,12,13 and application team is complaining of degraded performance. I can see that the cpu usage on the server is about 100% during the report generation , but everything else is fine. Free memory is 15gb , all mountpoints are under 80% and there is no other hardware issue as well.
Now app team is suspecting that last month patching could be the cause of the problem, because till last month they were performing this activity without having a performance degradtion.
I just need to be sure that solaris 10 recommended patches are not causing this issue. Any of you ever faced such an issue after patch installation ?
The server is V490 with 8 cpu / 32gb RAM. Any hints will be appreciated ?
Thanks in Advance.

Management console problem after installing recommended patch cluster

Hello everyone.
I just got a new SUN 440 server, it didn't come with the solaris os installed and so I installed solaris 9 12/03 to it. The installation went fine and I could start the management console with no problems at all. Then I went to sunsolve.sun.com to download the latest recommended patch clusters for solaris 9 (this was yesterday Sept.-06-2006), I downloaded the file, checked it with md5sum, unzipped it, went to single user mode and ran the install_patch script. After the patch cluster finished installing I rebooted the server for the patches to take effect, I logged in, tried to run console management 2.1 and it starts OK but I cannot use any services it offers because it says (in the console events):
"Server Not Running: no solaris management console server was available on the specified server. Please ensure there is a Solaris Management Console server available on the specified host and that it is running"
When I click on "See Exception" I get (for a particular service that is... in this case com.sun.admin.fsmgr.client.VFsMgr - for managing file systems):
java.rmi.RemoteException: Server RMI is null:
at sun.com.management.viperimpl.client.ViperClient.lookupServer(ViperClient.java:376)and so on...
I already checked that the service is running on port 898 and it seems that there is no other app. using that same port. I also restarted the service using /etc/init.d.init stop/status/start but I get the same results.
I don't know solaris very much and don't know what else to do, please help.
Thanks in advance.

Well, I guess what you see isn't what you get.
Guess I'm used to the fact USENET just left things formatted the way they were :-O

Static library not accessed properly after Solaris Kernel patch update !

Hi,
We are facing a sever issue in our application after our customer updated the Solaris 10 kernel patch u9 to u10.
We have two static libraries libdlib.a and libDLIB.a, with exactly same code base, but these two libraries are scattered across the code base and linked by many shared objects in our application.
However, one of the shared objects that links to "libdlib.a" library tries to access a function from "libDLIB.a". This behavior is causing a crash at a later point, since that shared object is supposed to access the function from "libdlib.a". Moreover, we found this is happening through the use of dbx.
I'm unable to understand why this problem surfaced after kernel patch update, though still the shared object works fine on Solaris 10 u9 patch.
Flow is something like this :
1. syslogrecorder.so gets loaded by one of the processes.
2. syslogrecorder.so is linked to "libdlib.a" at compile time, so it uses "libdlib.a" function DLIB_LoadLibrary and gets a handle to all the function pointers of the loaded library ( The purpose of DLIB_LoadLibrary is to load a shared library dynamically using dlopen )
3. syslogrecorder.so tries to do a "dlsym" and to do that it needs access to the library handle which we got in previous call DLIB_LoadLibrary. So syslogrecorder.so calls another function from DLIB_ProcAddress, which actually gives back the access to the loaded shared library.
Here is a catch in step 3, it is supposed to call DLIB_ProcAddress from the libdlib.a but as we observed from dbx output it does so by calling DLIB_ProcAddress from libDLIB.a and hence fails to give back the access to loaded shared library, causing crash at a later point in code.
Can someone put some light here that why this could happen ??
Thanks
Kuldeep

To clarify: You did not modify or rebuild any of your binaries, but after installing a kernel patch, the application stopped working. Most likely, something about your application depended on a accidental behavior of the runtime loader. That accidental behavior changed due to the patch, and your application failed.
For example, if there is a circular dependency among shared libraries, the loader will break the cycle at an arbitrary point to establish an initialization order. By accident, that order might work, in the sense of not causing a problem. A change to the loader could cause the cycle to be broken at a different point, and the resulting initialization order could cause a now-uninitialized object to be accessed. I'm not saying this is what is wrong, but this is an example of a dependency on accidental loader behavior.
Finding your actual problem will require tracing the sequence of operations leading up to the failure. You are more likely to find help in a Solaris linker forum. AFAIK, there are currently no Oracle forums for Solaris, and the old OpenSolaris forums have been converted to mailing lists. You can try the "tools-linking" list found on this page:
http://mail.opensolaris.org/mailman/listinfo
I also suggest you review the paper on best practices for using shared libraries written by Darryl Gove and myself:
http://www.oracle.com/technetwork/articles/servers-storage-admin/linkinglibraries-396782.html
If you have a service contract with Oracle, you can use your support channel to get more help.

CLOSE_WAIT problems with Oracle 9iAS on Solaris

All,
We have some simple JSP + Sevlets running on Oracle 9iAS on a Solaris server. After the App Server has been running for a couple of minutes we start to get several TCP connections with a CLOSE_WAIT status - as shown by a netstat output.
These seem to be a result of a FIN_WAIT_2 and CLOSE_WAIT pairing eg
Local Remote Swind Send-Q Rwind Recv-Q Status
SERVER.43009 SERVER.80 49152 0 49152 0 CLOSE_WAIT
SERVER.80 SERVER.43009 49152 0 49152 0 FIN_WAIT_2
Over time the FIN_WAIT_2 is removed, leaving the CLOSE_WAITs.
Has anyone else had this problem?
Keith

We're having similar problem. We have lot's of close_wait between Apache and OC4J.

Password problem in oracle 10g after upgrading from oracle 9i

Hi to all,
i'm migrating oracle 9i to oracle 10g. in oracle 9i username/password are same character(eg kareem/kareem)
after upgrading to oracle 10g will it create any problem. Because in oracle 10g the condition is when creating user is username and password should not contain same character (kareem/kareem not allowed).
Thanks in advance

in oracle 10g document, they have mention below condition to create user. See the second condition.
• Passwords must be between 4 and 30 characters long.
• Passwords cannot be the same as the user name.
• Passwords must be from the database character set and can include the underscore (_), dollar ($), and pound sign (#) characters.
• Passwords cannot be Oracle reserved words.
• Don't start the password with a numeral.
• Don's use change_on_install or manager as passwords, since they are used by Oracle.
As i'm going to upgrade oracle 9i to 10g. if it give problem because username and password are same then i have to request my development team to change the password in their application.Can you please verify and tell me.

Oracle 10g in Solaris Problem

Hi Guys , i was wondering how to start oracle database in correct way in Solaris
Because i had a problem with it..
i start the Oracle 10 in Solaris ,
the database is up. then after few hours, it shut down / the database is down for no reason then i have to start again
I was wondering whether there is a timeout? if there is how do i check it?
below as my step to start the database.
1. go to Oracle_HOME/bin
2. type lsnrctl start
3. sqlplus /nolog
4. connect username/password as sysdba
5. startup
any better way to start it??
after step 5, it shows no error and the database is ready.
i can connect using sql plus and toad from other computer.
But after few hours , it shutdown for no reason again..
anyone can help me?
is there any better way to start the database??
can i use nohup command in solaris to start oracle? how to do that?
Because of that , after my database starts , my web applicaton always hit
java.sql.SQLException ioException Broken Pipe then i have to restart my app server...
i heard broken pipe happens because the database is down without telling the app server is it??
Thanks...

Here are some additional statements for 10g on Solaris 10g x86:
1. Execute runInstaller with the -ignoreSysPrereqs option.
2. Select 'Do not create a starter database' when installing Oracle 10g.
3. During installation, the warning message 'SUNWsprox package not installed' can be ignored. Press Continue to resume the installation.
4. Download and install patch 4186426 from metalink.oracle.com after installing Oracle 10g software.
5. If you have an End User Solaris 10 distribution, install the SUNWuiu8 package prior to installing the 10g client.

MB.ACT light OFF --- after Solaris 9 recommended patch cluster applied

After applying the recommended patch cluster to several SunFire V210s/V240s the "system ready" or "activity" light on the front panel no longer illuminates. The systems come up fine and are fully functional, just no light.
While this has absolutely no impact on usability it is a bit disconcerting for the folks in the server room when glancing at the rack and not seeing the typical green light.
I first noticed the problem in mid 2007 and have tried patch clusters as recent as last month, but the light remains out.
One interesting discovery is that if I reset (hard) the ALOM module the light comes back on. However, if the system is subsequently rebooted for any reason the light does not come back on...
If anyone can shed some light on the issue I would greatly appreciate it!

Problems Installing Oracle 10GR2 & kernel parameters

Hi there,
I'm trying to install Oracle 10G on a new Solaris10 machine. After extensivley reading the oracle install guide and proceeding my install failed with an out of memory error.
Ive read the posts regarding many similar problems and to set the kernel parameters in /etc/system. My question for the experts is:
1). Is there a problem with the oracle install scripts and it not recognising the new features in Solaris?
2). Is there a more deep-rooted problem with oracle and solaris?
ANY help/advice would be much appreciated. There are hundreds of posts like this on the web and surely someone must have the answer? I mean surely oracle did not hack /etc/system to get their install to work did they??
Nibs

It IS a terrible experince to install oracle 10g on solaris 10. Tell us your system configuration and your installation step. For I have installed three times and each time a different problem. Suggest you go to oracle forum to get more help.

I am trying to Install Oracle 8i under Solaris 8 Intel version with Pentium 4 processor fixed.But iam'nt able to continue after I click "Install" button,the runInstaller exited badly with no response.I was told that even Installing Oracle under Windows P4 is facing the same problem,but on searching I got solution by renaming a DDL file before starting installation.Is there any similar method to do for installing it under p4 processor on solaris intel 8 version.

Dear Mr. Kumar, i am chandrasekaran from singapore, actualy i need your help regarding the intel sun os oracle. I have Intel Based SUN OS, but i try to get Oracle CD Any version either 8i or 9i for intel sun os.
One of my friend have the cd but it already damaged so that i need your help.
My address
S.Chandrasekaran, Blk 84 #07-93, Commonwealth close, Singapore 140084. If you have the cd you make one copy for me and send by post. Thank you

Memory issue, Oracle 10g in Solaris 10 zone

I know many memory questions have been asked, but I couldn't find any similar to the problem I'm seeing.
Starting from a fresh server boot, I have 12G of available memory, or nearly that anyway. Oracle 10g is installed with no databases created.
After creating a database and running a few sql scripts to create tablespaces and users, my available memory is down to 3.5G.
Rebooting the solaris zone containing Oracle does not restore any available memory. Shutting down the database does not restore any available memory.
Why does Oracle seem to absorb so much available memory and not release it? I created the database from scripts and restricted the overall sga by a good bit over the defaults and while this did reduce the memory the oracle processes use, I'm still seeing this continual absorption of memory to the point where running any imports takes forever because my memory seems to bottom out. I saw it go down (using top, and vmstat) to about 500M at one point.
Is there any utility that I can use, either solaris or sqlplus that will free up system memory?

What are your settings fpr SGA_MAX_SIZE, SGA_TARGET and PGA_AGGREGATE_TARGET?

Hmm that's really strange. We are running Oracle 9i on Solaris 10 Containers and didn't have any problems with memory leaks.

Problem: installing Recommend Patch Cluster: patch 140900-10 fails

I don't know if this is correct location for this thread (admin/moderator move as required).
We have a number of Solaris x86 hosts (ie 4) and I'm trying to get the patched and up to date.
I obtained the latest Recommended Patch Cluster (dated 28Sep2010).
I installed it on host A yesterday, 2 hours 9 mins, no problems.
I tried to install it on host B today, and that was just a critical failure.
Host B failed to install 140900-01, because the non global zones rejected the patch because dependancy 138218-01 wasn't installed in the non global zones.
Looking closer, it appears that 138218-01 is for global zone installation only; so it makes sense that the non global zones rejected it.
However, both hosts were in single user mode when installing the cluster and both hosts have non global zones.
140900-01 installed on host A with log:
| This appears to be an attempt to install the same architecture and
| version of a package which is already installed. This installation
| will attempt to overwrite this package.
|

It looks as if the patch strategy is completely different for the two hosts; both are solaris x86 (A is a V40z; B is a V20z).
Trying to use "-G" with patchadd crabs the patch is for global zones only and stops (ie it's almost as if it thinks installation is being attempted in a non global zone).
Without "-G" same behavior as patch cluster install attempt (no surprise there).
I have inherited this machines; I am told each of these machines were upgraded to Solaris 10u6 in June 2009.
Other than the 4-5 months it took oracle to get our update entitlement to us, we've had no problems.
I'm at a loss here, I don't see anyone else having this type of issue.
Can someone point the way...?
What am I missing...?

Well, I guess what you see isn't what you get.
Guess I'm used to the fact USENET just left things formatted the way they were :-O
