OAS 4.0.8.1 Performance - Redhat 6.1

I have noticed a few comments from other members of technet regarding Linux-based OAS performance.
I, too, have notice considerable lag times in web/admin requests (as compared to an NT install on a similar box).
As well, the java applet takes FOREVER to appear (and sometimes it just sits in an "applet initialized" state) as compared to my existing NT install.
Any comments?
matt

I have gotten just as far on RH6.0 Kernel 2.2.5-15. However when I start everything with owsctl start I see messages to the effect that "thread display not implemented".
Could this be related to the thread notes in the installation or is it the max processes exceeded kernel configuration issues.
Please email me at [email protected] if you have the answer and I will post it back here.
Thank you in advance

Adjust the max number of listener processes in listener config,
it defaults to 500 set down to around 200.

We had the same problem with the PL/SQL cartridge (OWS-04764 ...). We solved our problem with a new kernel. Its important that you have a kernel with symmetric multi-processing support (SMP) enabled, independent if you have a one or two processor machine.
I hope it will help you.

OAS 4.0.8.1/Redhat 6.2? WRKSF problem

Hi, I've installed OAS 4.0.8.1 on Redhat 6.2 but when I start the processes up the WRKSF goes down after a few seconds, I've seen a previous posting on this subject had a workaround proposed by Dennis Irwin which seemed to work for many people, unfortunately it didn't for me, I've spoken to Oracle about this problem but all they say is OAS 4.0.8.1 isn't supported for the 2.2.14 kernel in Redhat 6.2, 4.0.8.2 will be but they can't say when it will be released, until then OAS is basically useless for me, has anyone any suggestions?. Thanks, Geoff
null

According to ORACLE representatives, OAS 4.0.8 isn't their major priority : since Oracle iAS will be available in few days, and many less CPY and memory hungry as OAS, can't you wait a bit longer ?
An other point is that oas 4.0.8.2 will probably be one on their last release of this product ...
Take a look at the oracle iAS white paper, the product will be more reliable and standard : essentialy based on Apache 1.3.12, mod_java, mod_pl and JServ 1.1, and Oracle 8i Cache...

OAS 4.0.7, RedHat 6.0, PL/SQL catridge

Application Server didn't starting successfully
after OAS 4.0.7 installation on RedHat 6.0 .
That problem was solved by changing ps utility
to script from one of the previous threads.
Now Application Server start succesfully,
but I have new problem.
I get time-out error, when I try to call any PL/SQL URL
(for example, PL/SQL "Hello, world!" or Database browse utility).
Then used listener (admin or www) don't worked, and
I can't to stop it or all Application Server by "owsctl stop".
Processes keep in memory.
Does environment variable ORAWEB_NAMEROOT any
connection to this problem? It sets in owsenv_bsh.sh:
ORAWEB_NAMEROOT=/.:/application/oracle/OAS
What ideas?

Hi,
i have the same problem in SuSE 6.2.
The oracle hotline told me that OAS407 is only certified and
supported ageinst linux kernel 2.0.34. My SuSE distribution

OAS 4.0.8.1 + Apache web listener

Help!
I'm not having all the problems running OAS 4.0.8.1 on Redhat 6.1 that everyone else is (my processes stay up and it's significantly faster than 4.0.7.1 on RH 5.2). But what I'd really like to do is dump Oracle's Spyglass web listeners and run Apache instead. This includes all cartridges and such as well as standard HTML. I'm mostly interested in the PL/SQL cartridge, but all working would be nice.
This can be done by compiling Apache specially with MOD_SO support and registering Apache as a listener. The very sketchy directions are in the docs under the Administration section. The directions are very poor (thank you again Oracle, we wouldn't want you to actually write good docs, it would spoil us for the years of terrible documentation) and I can't quite get it to work. I get Apache compiled and the shared objects libraries load, I think.
When I start Apache, it says it starts but it really doesn't. Dies immediately and doesn't show up on the process list. The error logs shows the following message:
(111)Connection refused: OAS Adapter: Error connecting to dispatcher
This is a major issue for me and any help would be appreciated. Anyone had any luck getting this to work?
Thanks!

Dear jgerry,
Congrats on getting Apache compiled. I am new to all of this, and the documentation is poor. The way I understand the documentation on www.olab.com, libapadp.so must be linked into Apache. Is this true? If so, I would love to know how to recompile it. I have downloaded and unzipped/untared 1.3.12, but I can't find out how to just link in a .so file. The only references I see are how to start out with a .c file. I have fould libapadp.so and ndwfapd.so in the Oracle install. I thought that just doing "LoadModule ows_module ndwfapd.so" would do the trick if I put ndwfapd.so and libapadp.so in the modules subdir of my Apache 1.3.9 installation, but I get the message...
"Cannot load /etc/httpd/modules/ndwfapd.so into server: libapadp.so: cannot open shared object file: No such file or directory".
Do you have any ideas to help me over this hurdle.
Any help is appreciated.

OAS 4.0.8.1 - more wrksf problems?

Running OAS 4.0.8.1 on Redhat 6.1 (kernel 2.2.14-32)
There seems to be alot of discussion regarding the "wrksf" service in the latest release of OAS (4.0.8.1). I'm also having trouble getting the "Cartridge Service Factory" to start properly.
I use the OAS manager to start, with the following results:
Please wait while the command is being processed on host dev ...

waiting for ORB to be ready...
The command completed successfully on host dev.

I get the same results if I attempt to start from the command line with owsctl:

The command completed successfully on host dev.

I have used the OAS 4.0.7 on Redhat 5.2 successfully with very few problems, but we would like to be able to use OAS on Redhat 6.1.
Has anyone else experienced this problem? If so, are there any know solutions or workarounds?

My experience with wrksf, on Mandrake 7.0 (RH 6.1+) is that wrksf starts at first, then bails after about a second.
I have a couple cartridges installed, C and Perl, and it starts those cartridges up and then fails. I don't get the same error message that you do, but there is an error in the wrb.log:
`OWS-10911: Throwing exception for reason: wrkpGetProperty 2 `
`OWS-04793: Operation oracle_OAS_System_CartridgeServerFactory_create_nwreturns exception IDL:omg.org/CORBA/UNKNOWN:1.0 `
I'm not sure what this is all about, but it does start up my cartridges at first, because I specified a mininum number to start up initially, and a minimum number of instances.
They just don't come back if terminated, since wrksf isn't there.
BTW, this is the same error I encountered when, on NT, I compiled a c cartridge with Metroworks CodeWarrior instead of MS Visual C++ v6.0. So I wonder if this has something to do with compiler incompatibility, if wrksf was compiled with a different compiler from the rest of OAS. While compilers don't usually matter for C, they do for C++, and all binaries and libraries must be compiled with the same compiler/linker to work together.
Just a stab in the dark.

OAS 10.1.3 not responding after a day of work!!!

Hello everyone... I have a strange case. I have installed a 10.1.3 OAS in a linux server running RedHat ES 4.0 and deployed a java web app..
The thing is that the users connect to the web app. and work without problems all day long... BUT the next day, when they try to enter to the app. the browser times out the request and nobody can enter and use the app!!!, to solve this problem I just simply go to the server and restart the OAS and then everything goes back to normal... I installed this app. 4 days ago and the same thing repeats everyday.
The first thing I did was check the logs in $ORACLE_HOME/opmn/logs/opmn.log y $ORACLE_HOME/opmn/logs/OC4J~home~default_group~1 but I can't find any errors only a WARNING:
WARNING: Code-source /u00/oracle/product/10.1.3/OracleAS_J2EE/j2ee/home/applications/masivo/masivo/WEB-INF/lib/classes12.jar (from WEB-INF/

be masked as the latter is already visible in the search path of loader masivo.web.masivo:0.0.0.
I am an OAS newbe and don't know what else to look for.
Thanks for the help!!!
Ah, I have modified the opmn.xml file and changed the following line (for the start options):
<data id="java-options" value="-Xms1024m -Xmx1024m -XX:PermSize=1024m -XX:MaxPermSize=1024m -Dcom.sun.management.jmxremote -server -Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false"/>

Oracle AS already have jdbc driver for oracle => you can delete file u00/oracle/product/10.1.3/OracleAS_J2EE/j2ee/home/applications/masivo/masivo/WEB-INF/lib/classes12.jar
PS: Runtime parameter PermSize may be to large.
I think you should change to
-Xms512m -Xmx1024m -XX:MaxPermSize=128m

Sorry I have to answer my own question.
When you install w/OAS 4.0 on RedHat 6.0,
you have to have the tcl-8.0.3-20 in place.
I had tcl-8.0.4-29, so this really made the
installer really up set. But, once I changed
to the lower version, it worked. There, I
answered my own question.

Oracle is going to stop OAS development

I heard from an Oracle employee told me that
Oracle is going to stop OAS due to its poor performance.
Is that true?

WHAT! We are in the process of spending about $250,000 to use this more of this architechure for internal sites. We have found OAS to be great. It would be a shame for Oracle to drop this, but if you have more information please share!

Is ORACLE slower on Windows then on Linux ?

Hi,
I'm suppose to choose the platform for Oracle .... Linux or Windows 2008 Server ...
Ones we've installed Oracle on Windows 2003 Server and it was really slower like 200-300% ..... we did simple default install
Does anyone know if this is a fact that Oracle will run slower on Windows platform then on any other ? Any experiance with that ? If we are talking about 5-10% then this is ok and I'll stick with windows ...
Cause I know how to deal with windows much more then how to deal with Linux admin, install and other stuff ...
Thank you...

Hi Charles,
Installing a virus scanner on the server, especially if it is permitted to scan program and data files used by Oracle.Ha, that a good one! That the FIRST thing I check!
Also, I've seen high demand screensavers (fractals) clobber Oracle performance . . .
Oracle on Windows uses a thread modelThat's actually one of the few "positives" about running Oracle on Windows . . .
rather than providing a performance comparison between Linux and Windows.Fine, try here:

"Roby Sherman performed an exhaustive study of the speed of Oracle on Linux and Microsoft Windows using identical hardware. Sherman currently works for Qwest Communications in the data technologies group of IT architecture and transversal services. He is a recognized expert in designing, delivering, tuning, and troubleshooting n-tier systems and technology architecture components of various size and complexity based on Oracle RDBMS technology.
Sherman concludes that Linux was over 30% faster:
"From perspective of performance, RedHat Linux 7.2 demonstrated an average performance advantage of 38.4 percent higher RDBMS throughput than a similarly configured Windows 2000 Server in a variety of operational scenarios." Sherman also notes: "Another point of contention was Window's lack of consistency between many database administrative functions (e.g., automated startup, shutdown, service creation, scripting) compared to what DBAs are already used to in many mainstream UNIX environments (e.g., Solaris and HP-UX)."
Mr. Burleson's comments seem to be out of line. No, I'm right on the money.
*I've seen enough companies get burned by Windows (unplanned outages, data corruption) to speak with confidence.*
Bottom line, it's malfeasence to recommend any OS platform for a production database application that has an unsavory history.
It does not take a genius to figure out that an OS with this kind of history should not be used with any data that you care about:
- "blue screen of death"
- legandary security vulnerabilities
- memory leaks you could drive a truck through
- Patching weekly
- The world's most incompetant tech support
I'm not alone in this opinion:

Good point on the screen saver.
Comparing Windows 2000, released in March 2000, with Red Hat 7.2 which was released in ... sorry, forgot the date, but I put in a couple servers running that release of Linux into service in 2001. I was kind of hoping that you would have an article which pits Windows 3.1 against the original Linux release. :-)
You might be happy to know that things have changed significantly since Windows 3.1, and also significantly since Windows 2000. There were many improvements in Windows 2003 over Windows 2000 (I happened to read a couple large books on the subject of Windows 2003 Server a couple years ago). This page contains a couple links that you may want to browse:

Windows sucks... I have heard that the Microsoft Windows operating system is on barcode scanners, phones, and even car navigation systems. I had no idea that vacuums also utilized Windows, thanks for the heads-up:

Regarding blue screen of death, those are rather rare with versions of Windows since the release of Windows 2000. The last blue screen that I saw on a server happened when an ECC memory module started experiencing multiple hardware bit errors which could not be corrected by the ECC memory logic. The server hardware forced the blue screen to prevent data corruption. The previous blue screen? A Windows NT 4.0 Server (circa 1996) when a new RAID controller was added to the server.
Regarding legandary security vulnerabilities, well I don't think that it quite qualifies as legendary. However, given the wide usage of Windows (particularly by people just starting to learn to use computers), there will very definitely be more security issues to contend with - Windows often offers a larger attack surface than other operating systems. Yes, there have been many security problems over the years.
Regarding memory leaks you could drive a truck through, I have to say that in a server environment I have not experienced that problem. On a desktop environment, I would say that it is typically the fault of poorly written applications which cause the memory leaks. Windows will often clean up after the poorly written applications when they are closed.
Regarding patching weekly, yes there are typically frequent security and bug fixes released for the Windows platform, but I suggest that if someone is patching weekly on a server, there is probably a larger problem to be addressed.
Regarding the world's most incompetant tech support, I am not sure that I follow your logic:

Suggestions:
- Make sure all words are spelled correctly.
- Search the Web for documents that contain 'incompetant'"
As previously stated, consideration should be given to the operating system which is most familiar to the OP.

JNDI replication within a cluster

Hi to all of you,
we successfully enabled HTTP Session replication and tested the failover. We would also like to setup a JNDI replication, so that we can use it as a storage for some shared data -- as stated in http://download.oracle.com/docs/cd/B10464_05/web.904/b10324/cluster.htm this should be enabled automatically, once EJB replication is enabled.
With some problems we finally enabled EJB replication (we configured it through orion-application.xml) and the required replication policy is propagated to our statful beans. Anyway, the JNDI is still not replicated over the machines.
We are running latest OAS 10g, cluster is MultiCast on RedHat Enterprise, replication policy for Stateful beans is set to 'onRequestEnd' (we tried all the options :), our application is normal ear with 1 ejb and 1 war archive and apart from JNDI replication, it works as expected.
Is there some trick that is not mentioned or that we may overlooked in documentation to enable JNDI replication?
Kind Regards,
Martin

Hopefully solved -- though the documentation explicitly mentions rebinding as not working, after any changes made to value stored in JNDI context you should just re-bind the value to the JNDI context; the value is replicated to other JNDI contexts.

Performance issues with Oracle EE 9.2.0.4 and RedHat 2.1

Hello,
I am having some serious performance issues with Oracle Enterprise Edition 9.2.0.4 and RedHat Linux 2.1. The processor goes berserk at 100% for long (some 5 min.) periods of time, and all the ram memory gets used.
Some environment characteristics:
Machine: Intel Pentium IV 2.0GHz with 1GB of RAM.
OS: RedHat Linux 2.1 Enterprise.
Oracle: Oracle Enterprise Edition 9.2.0.4
Application: We have a small web-application with 10 users (for now) and very basic queries (all in stored procedures). Also we use the latest version of ODP.NET with default connection settings (some low pooling, etc).
Does anyone know what could be going on?
Is anybody else having this similar behavior?
We change from SQL-Server so we are not the world expert on the matter. But we want a reliable system nonetheless.
Please help us out, gives some tips, tricks, or guides
Thanks to all,
Frank

Thank you very much and sorry I couldnt write sooner. It seems that the administrator doesnt see the kswap going on so much, so I dont really know what is going on.
We are looking at some queries and some indexing but this is nuts, if I had some poor queries, which we dont really, the server would show pick right?
But he goes crazy and has two oracle processes taking all the resources. There seems to be little swapping going on.
Son now what? They are all ready talking about MS-SQL please help me out here, this is crazy!!!
We have, may be the most powerful combinations here. What is oracle doing?
We even kill the Working Process of the IIS and have no one do anything with the database and still dose two processes going on.
Can some one help me?
Thanks,
Frank

Performance with OAS 9i

Has any body deployed forms, developed in Form6i, on Oracle Application Server 9i.
Is there any performance improvement with OAS 9i as a new feature 'Form services' has been introduced?
Is it now suitable for making big web enabled applications?
Ajay

You shouldn't need to worry about the installer as it uses the correct jre on it's CD. I just ran it from the kde command line ie: /mnt/cdrom/runInstaller.
You don't need the database on the same machine, just set up iAS as a client to your database ie: set up TNSNAMES.
That said, the installation of 9iAS always failed on my RH7 and I've had to crank the install files by hand. 8iAS never seemed to have the problems.
