Application server performance

Hey friends,
I have a lot of user made procedures built in the program units of forms.
Since ia m in a process to make a web server of teh forms application, i wanted to know that would these program units cause any performance problems on the application server.
Since the processing of thses program units would occur at application server.
Do i have to create these procedures at database level?
thanks
Thanks

I checked the logs and all is well and nothing unusual, I followed another replys suggestion and put a timestamp in throught the process. It shows a consistant 6.xx minutes to return yet little time is spent at the database and precompiling my JSP made no difference (as well as every other parameter I could tweak). I have since taken my WAR file and dropped it into BEA's Weblogic Express - works fine and JBOSS 3.2.5 - works fine. I know my application is fine and every server but AS8 that I have tried works fine. I am waiting for Sun to care enough to call me back (I have left many voicemails and been routed all over the place, everyones first name seems to start with David) untill then JBOSS is the winner since it is free and works. Thank you for the replys and help.

Sun Java Application Server Performance with Web Services

We are running a web service on SJAS (Standard Edition). Load testing under 1 or 2 users works alright, but with 5 users making concurrent web service calls it immediately crashes the domain. Has anyone else run into performance issues when using SJAS with Web Services? Are there any configuration parameters we need to setup to handle more than 1 connection?
I'm sure that the application server can handle many concurrent connections, just not sure how to configure and where to look for more information. If anyone is aware of actual numbers for load testing, that would be great information.
Thanks,
Dawson

Hi Dawson,
SJSAS can definetly handle more users. Can you please tell us, what version of SJSAS and web services (jax-rpc 1.1 or jax-ws 2.0?) implementation you are using? When you say it crashes the domain, do you see any error messages in the server.log?

Application Server performance issues

I am a DBA consultant at a county government site that recently went live on FSCM 9.1 using Tools 8.53.04 Running Windows Server with MS-SQL Server 2012
A problem has started with our two Prod App Servers. There are a few hundred Accounting users on the system and they have been reporting extreme slowness going page to page, and many times getting kicked out of the system. I have launched Process Explorer, Resource Monitor, Task Manager on both App Serves and found individual PSAPPSRV processes peaking as high as 39% CPU and then bouncing down to 2%, back up to 17%, and all over the map
In PSADMIN I ran TMAdmin and shut down and then rebooted the individual processes that had the high cpu usage, but they spiked back up.
So we sent out a message for users to log off and bounced both app servers and cleared app server cache, however that didn't fix it either. This is the first time this has happened, so we ar soliciting feedback from other PS/MS-SQL DBA's to see if they have experienced this and how they handled it.
We looked at resources and each App Server (they are virtual) have only 16 GB of ram and each has two Opteron 2.79 Ghz processors. So we are thinking it is a resource problem, however this situation has not happened before
Thanks in advance

The problem is there is no service timeout for the PSAPPSRV process:
[PSAPPSRV]
;=========================================================================
; Settings for PSAPPSRV
;=========================================================================
; UBBGEN settings
Min Instances=5
Max Instances=5
Service Timeout=0
Please review the following Km Doc E-AS: PSAPPSRV process Service Timeout=0 Causing Severe Slow Down of Application (Doc ID 1992038.1)
This can happen if the psdbgsrv process gets started: E-AS: Service Timeout for PSAPPSRV reverts to = 0 after Domain Configuration (Doc ID 664081.1)
Please set the psappsrv process back to the servicetimeout of =300 after reviewing the above km docs and this should fix the issue.

Hi Raja,
I tried the same. But it not populating the table and giving an error message in the return table "line   1 col   1-unexpected symbol; expected '<', '</', entity reference, charac".
I can't find any ' ; ' in the XML file. What could be the possible reason of error?

Slow start-up for JSF projects on Sun Java System Application Server 8.2?

App. Server: Sun Java System Application Server 8.2
I really don't understand why a JSF project starts-up so slow on Sun Java System Application Server 8.2.
I've gone through the "Overview of Sun Java System Application Server Performance" guide and tuned my server.
It's not memory or processor, I am developing on a SunOS 5.8 Generic_117350-27 sun4u sparc SUNW,UltraAX-MP.
The JSF project contains one index.jsp and one login.faces - that's it. But it takes up towards 15 seconds to load the page, if I type:
http://<domain>:8080/login/
I would believe that the application should be a lot faster.
What can I do to solve this?
Thanks,
--Todd

Yes I am.
Right now I have:

Bea Weblogic Server performance question.

Hello,
Im wondering if there are big performance difference between Bea Weblogic Server
versions.
I run BWS 5.1 and find it great, I ve tested the application on 6.0 and it seems
to run as good as 5.1, I ve tested with 6.1 and it works fine too.
And now is my question... is it big difference between WLS from 5.1, 6.0, 6.1,
7.0, 8.0, 8.1 ???
I dont need any "super-hyper" features just run a simple EJB (30-40 EJBs) application.
If there are big performance difference then there is a good reason to update
to the latest WLS. (Do you have any benchmark urls for this issue?)
Do I need to modify the EJBs if I want to upgrade from 5.1 to 8.1 ??
When I upgraded from 5.1 to 6.1 there was a little changes I ve to make in the
xml files.
Thanks for all your help!

As new versions release, there is differences in performance. One
significant point to note is the JVM versions that are supported which
significantly impact the application server performance. The new WLS 8.1 on
the newest released 1.4.2 JVM is damn good. The 1.4.1_0x JVMs have been
dramatically slower in tests that I've done. So even incremental releases
will make an impact.
In newer releases, code matures also. I also believe in 7.x they gave the
capability of clustering JVM more effectively.
anyway... good luck.

Application Server Tuning

Hi there,
Actually I have a full iPlanet solution up running on Solaris 8 environment, which contains:
-iPlanet Application Server 6.5
-iPlanet Directory Server 4.1
-iPlanet Web Server 4.1
-iPlanet Integration Server (EAI) 2.6
-iPlanet Portal Server 3.0
-Netegrity Site Minder
And I want to monitor the Application Server performance and to tune the required parameters.
So that, firstly I want to know what is the services that I should monitor to make sure that the Application Server is up and running and performing well.
And then, I want to know if there is any tool which can help me evaluate the Application Server performance and find out the proper tuning parameter in case if it is needed.
Many Thanks

There are some tuning tips available at the following url :
http://docs.sun.com/source/816-5794-11/index.html
hope this might help a bit !!

I have a dual Xeon 2.6 computer with 3 GB of memory and 6 GB of cache, running RedHat EL 3 with Oracle AS 10g (9.0.4.0.0).
Application Server is used to run some applications created with forms, and it generates several reports, but the forms are also used as a front end to another Oracle Database (Oracle 7.0, runing in Sun Solaris 5.6).
I've notested (and also my users) the application is getting very slow (is running in a dual Xeon, with 2 Gbit nics, in a 3 Gb backbone).
The speed (or lack of it) is most noted when the forms are generating the reports (it used to be fast - 2 seconds) and now it can take up to 5 minutes.
The AS 10g, when generating the reports, almost all of the querys go to the other server (in Solaris) and the results return to the server, and then the report is generated. The network has no problems (at least, that i know of), and the network performance is not an issue - both the servers are connected to a Gbit switch.
Can someone may have an ideia of it can be?
even in the clients, when running the forms application, the transition of the several menus is slow, and it used to be more fast.
the 10g is using Java Jinitiator 1.3.18. Can it be from that ? i'm not certain, but i could say this things start happen when we upgraded the jinitiator from 1.3.13 to 1.3.18...
My users are really getting on my nervers and i cant do nothing, because they have reason...
any help would be appreciated !
Cheers

Bruno, did you solve the performance problem? I'm experiencing the same lack of speed.

How to improve the performance of applications in Oracle Application Server 9i ?

I have my applications deployed to Oracle 8.1.7 database using OSE in Oracle Application Server 9i. My machine has 256 MB RAM. It has both Oracle Application Server and Oracle 8i database server installed on it. When I try running my applications I find they are very slow. Can I get some guidelines using which I can better the performance of my Application? It can be in the form of code, memory ,disk space etc.
Thanks in advance,
Regards,
krithika.

The system configuration is more than enough to run java applications.
You are probalbly doing time-consuming operations in the event thread. Which blocks the event thread and the gui seems not to be responding. If you you have a very bad design.
Use a thread for time consuming operations.

Does turning on Hprof hurt performance in an application server?

i'm running WebSphere Application Server v6.1 on HP-UX, which runs on Hotspot VM by default.
Since Hotspot won't produce anything like javacore or heapdump. I would very much like it to turn on Hprof all the time. So that I have some material for analysis if an application server hang or performance delegation occurs.
However I hardly find anyone saying they've turned on this option for WebSphere, nor does IBM redbooks. Would this hurt performance to turn on hprof for WAS JVM? or does this bring along any performance hazard? I'm planning to have this option on all the time in my production servers.

Have you heard of HPjmeter? Try running with -XX:+HeapDump -XX:+HeapDumpOnCntrlBreak (i'm not sure of the syntax o the latter option, but its documented in the HPjmeter user manual. Any further questions ask me - I used to develop the tool.

Slow performance of Application server with a 9i database.

I am experiencing extremely slow perrformance of my 1.0.2.2.2 Application Server portal with my 9.0.1.2.1 database.
After logging in it takes forever just to connect to the Portal home page and even longer using the navigation link to connect to 'my pages'.
This degradation of performance pretty much happened over night. One day it was fine and the next it seemed to hang on every movement.
My server is running on Win 2000 with 1 GB of RAM. I ordered another GB of RAM hoping to alleviate a little of the congestion. I think it must hhave something to do with all the indexes, but I don't know how to tune the DB for it.
Does anyone have any idea of how to tune the DB to work with the Application Server portal? I am developing this portal for a client and I hate to think what will happen when it becomes fully rolled out and robust.

I tried to do a simular thing, but I did not notice a performance decrease. However it might be possible that this happens. For example, if you are calling a time critical vi in the second while loop, it will lock all other processes until it is finished. Or maybe you are calling a shared resource (allocate an array, access to a file, using a mutex) that the other loop holds. Until the shared resource is released the first while loop must wait before it can access that resource (memory, file, etc.).
Without looking at the source code it will be hard to say what is causing it. I recommend to remove part by part subVI's from the second loop, to debug where the problem exists. If you want I can have a look at the code, please reply to this thread.

[Question:] Performance issue while deploying on Application Server

Oracle Application server 10G release 3 is used on which Jheadstart built application need to be deployed. but when its deployed it get very slow.
What are the things i need to check so that it can speed up . like disabling any Debugging messages, log, or other particular messages which can increase performance.

If you are getting "running_without_metadata" this means the Agentry server did not load any application on start up.
1) In your Agentry.ini in the [Configuration] section what is developmentServer set to?
2) Depending on the value is where the Agentry Server looks for the application logic in the following locations:
Set to" True"
C:\SAP\MobilePlatform\Servers\UnwiredServer\Repository\Agentry\default\com.sap.agentry.wm53\Application\Development\
Set to false:
C:\SAP\MobilePlatform\Servers\UnwiredServer\Repository\Agentry\default\com.sap.agentry.wm53\Application\Production
In the above folder does it contain your application logic?

Application Server and performance with Attached Libraries

We are moving toward Forms 9i and 9iAS.
I have common SQL code that should be accessed from many Forms and considering
between creating Database Packages and Oracle Forms Packages as Attached
Libraries.
Have been told that they both operate differently with the Forms PL/SQL packages
loaded 'thinly' (only the components being called and also in 4k memory size).
So there is an argument to go for Forms Package as opposed to Database packages
this way!.
Obviously the Forms package will be loaded somewhere in a Run Forms session, but
does this means other Oracle Forms programs can access the loaded program unit.
Let me say user A running Forms A has an attached library which is also accessed
by user B running Forms B but trying to access the same program unit in the same
attached library.
Would the 9iAS recognise this and load only one copy, assuming user A started
first and hasnt closed his/her session while user B starts Forms B soon after?

You should probably ask this on the Forms discussion forum.
http://www.oracle.com/technology/discussionforums/forms.html
But in general Forms on the Web share objects in the memory on the application server - including plls.
