Recommended tuning parameters 10gAS 9.0.4 for 500 users

Hi,
we have Oracle 10gAS 9.0.4 deployed on multiprocessor windows using J2EE + WebCache type of installation
couple hundred EJBs, signed applet as the client gui
datasource connection pool using oracle thin driver
what would be the recommended tuning parameters for 500 concurrent users hitting this web/appserver?
Thanks,
Arpad

Dear Malmstrom ,
Hope U R fine,
I am New to Oracle AS. We r deploying an application created in Oracle forms and reports 10g using Oracle database 10gR2 and FRServices 10g.
We r facing a no. of problems
1). A very frequently accessed form generates FRM-92102 while accessing using web.
while other forms seems to be ok.
2). We r facing Some times Reports generated using Oracle forms does not display page or hangs.
What we accessed is that We have just Installed Oracle FRServices and did not configured it.
Both oracle Database and FRServices are on one machine using windows 2000 Adv. Server which is an IBM dual processor machine with 2G RAM and 2G Virtual Space.
We r also going to shift Oracle database on RHEL 4.0 with Database 10gR2 using the same machine while we have planned to install FRServices on a seperate machine that is P4 2.8 with 1G RAM + 2G Virtual Memory.
Our requirement is that Maximum of 200 users with 40 concurrent sessions.
PLS suggest us the recommended settings for Oracle FRServices.
Thanks and waiting for ur reply.

What are the AM Tuning parameters need to be set for 500 concurrent users

Hi All,
We are using JDEVADF_11.1.1.5.0.
What are the exact AM parameters(Pooling and Scalability tab) to be set when we planned for 500+ concurrent users?
Along with this do we need to set any parameters at weblogic server level, if any please give inputs.
Any input's would be appreciated.
Thanks in advance.
Regards,
Dinesh

We can?t give you exact numbers as there are many factors influencing the performance. In hte end you have to make a load test to find the right set of parameters. A good starting point is Andrejus's blog Andrejus Baranovskis's Blog: Stress Testing Oracle ADF BC Applications - Internal Connections and Andrejus Baranovskis's Blog: Stress Testing Oracle ADF BC Applications - Do Connection Pooling and TXN Disconnect Level

Setting of init.ora file for 500 users

how to set diffrents parameters in init.ora file
for 500 user
(hybrid system)(oltp+dss)
thanks

Yeah, it depends and you will need to adjust thoses parameters during the "life" of the database.
I give you some of my thoughts (that's just thoughts, not a rule => there is no perfect rule) :
500 users = Unix box i guess so :
If MTS (dont think u need MTS for 500 users) => SGA = 75% of the RAM of the server
If NOT MTS (dedicated processes) => SGA = 50% of the RAM
Say 2GB of RAM on no MTS :
buffer cache = 900 MB
shared pool = 100MB to 200 MB
sort_area_size = 256KB
something like 50 to 100 RBS (depends on how many users are connected simultaneously)
for the users which will not do some OLTP operations, you should make few BIG RBS and assign their transactions to them. for thoses users, you probably need a bigger sort_area_size.

Licence limitation for 500 users

we use acrobat 9 pro. we have loaded pdf forms toour site. these forms are for our customers use. we've built a button on the forms that submits the form, i mean, it
transmits the data that our customer typed on the form to our site. do i have to use a special license to do that? does your answer
change if i use a rights extended form or a non extended right form?

a) The limitation only applies to extended rights documents
b) The limitation only applies to extended rights documents
So you can use a submission button to your hearts content and not reach a limit UNLESS you have that same form with the extended rights. Once you've done that to a form you can only collect 500 instances of date whether it be through receiving the filled in form, hard copies of the form or people using a button to submit the form.

DESIGN-WLAN for 500 users

I have a client who want to implement a LAN in a new corporate site, and he want to implement all the LAN in a WLAN. The office is a three floor building where the company assign near 200 users per floor. Each user employ windows xp system with office, sql DB, file system, etc.
I search in the Cisco web page but I did not find example of a similar implementation. It is factible to implement? Has the WLAN a similar performance that a wired LAN?

You can build a wireless network like this, but you need to be aware that wireless has significant bandwidth limitations.
It is easy to build a wired network where each user will have guaranteed 10 Mbps connections to the server resources. This is especially true for a site with only a few hundred users per floor.
A wireless network, on the other hand, involves a great deal of planning in order to make sure there is sufficient wireless coverage and bandwidth. Users connected to a wireless access point share the bandwidth available to that access point--must like in the days of 10BaseT hubs or 10Base2 Ethernet. On an 802.11a/g network, the best shared throughput you should expect is 22 Mbps.
Here's my advice if you really want to build a network like this:
Unified Wireless is a must. You cannot be bothered to constantly tweak the settings on the 30 access points you'll probably end up installing.
5Ghz! You want to have a dense deployment of access points. That way you will have fewer people on one access point, and should an access point fail other neighboring access points can pick up the users who otherwise would be left without a signal. Do not play with 802.11g on the 2.4Ghz spectrum. 802.11a on the 5Ghz spectrum will give you 8 indoor channels and allow for a dense access point deployment. Try to keep your users per access point under 12.
Consider the AIR1252AG access point with support for 802.11n-draft 2.0.
If the client is considering doing this wireless implimentation to save money: get out now. They are going to try and build a bargain basement wireless network and it will not work. Users will be unhappy. You will spend weeks trying to troubleshoot dead spots and noise spots. A properly implimented wireless network is just about as expensive as a wired network. On top of that, it will be slower and more prone to failure. The only real advantage of wireless networks is mobility. Users can move around, office cubicles can be rearranged, and costs are saved in the long term.

How to change sip address after changing email address for bulk users

We are in the process of adding new primary email address as [email protected] for 500 users.
current primary email address is [email protected] and
currently all LYNC users has sip address as [email protected]
Now we need to change the LYNC SIP Address as their primary email address ( [email protected]). does any one has script to pull the users from CSV and change the SIP Address as their primary email address.
I got below script from internet , but this is not going to help me, as this script is to enable SIP Address and mark the sip address as same as the email address.
any help in this matter is greatly appreciated.

Teaming 2.1 for 500 active user

We are planning to setup a Teaming 2.1 server for 500 users ( about 30-40% of simultaneous connected users) in a High-availability environment.
May I know how we size the hardware?
2 Server with Teaming and MySQL ?
We are thinking to Clustered both Tomcat, Lucene and also MySQL.
But MySQL database script is in InnoDB, which is not supported in MySQL Cluster. Any idea?

DB tuning parameters for APEX

I have APEX running on Large Linux box with DB version 11.1.0.6. The database was installed with the default parameters. I am seeing some sporadic performance where pages display fast 9 out 10 times, but the 10th time it takes a minute or so to display. Has anybody had any experience with DB tuning parameters needed for running APEX?

APEX uses shared_server so, depending on your workload, you may not have sufficient allowed. Check you shared_server parameter. You may need to increase it to accommodate more concurrent users. Other than that there is not much advice available until you tell us more. For instance, what do your database advisers reveal about shared_pool, sga, pga, db buffer cache...?

Oracle 11g R2 Tuning Parameters

Hello,
I am trying to gather some basic tuning parameters for Adobe Livecycle application which can be applied on oracle database.
Are there any set values and configurations provided with Adobe as best practices apart from the ones mentioned during creation of database and schemas.
Thanks

Hi,
This was useful. What i tried was that during instance creation i can run custom script. As part of custom script, i set the parameters and the script restarts the database instance. With that i am able to set the parameters and get the values set.
Thanks,
KrishnaWhat I'm missing is WHY?
Why are you concerned with not restarting the database? You are creating a database. That means there is no pre-existing database, no pre-existing application, no users. No one to care if you bounce it. So why is it important to NOT have to bounce it one last time after you have created it?
I'm glad you found a solution, but it appears to be a solution in search of a problem.

CTS+ Performance Tuning Parameters

Hi Experts,
Same Transport is imported in 2 PI Systems lets say PI1 and PI2.
In PI1 the import is very fast and in PI2 it is slow.I did a RFC Destination CTSDEPLOY Connection test and found that in PI1 system it is taking much less time than in PI2.In PI2 system time taken is almost 3 times of time taken in PI1.
Can you please let me know what is the reason?Is there any performance tuning parameters that needs to be configured?If yes can please let me know how and where i.e; in details?
Regards
Anik
