Oracle Application Performance Tuning

Hello all,
Please forgive me if I am asking this in the wrong section.
I am a s/w engineer with 2 years of exp. I have been working as a performance tuning resource for Oracle EBS in my company. The work mostly involved SQL tuning and dealing with indexes etc. In this time I took up interest in DBA stuff and I completed my OCA in Oracle 10g. Now my comany is giving me an oppurtunity to move into an Application DBA team and I am totally confused about it.
Becoming an Apps DBA will mean that the effort I put into the certification in 10g will be of no use. There are other papers for Apps DBA certification. Should I stay put in performance tuning & wait for a Core DBA chance or shall I accept the Apps DBA oppurtunity.
Also, does my exp. in SQL performace tuning hold any value as such with out an exposure to DBA activities?
Kindly guide me in this regards as I am very confused at this juncture.
Regards,
Jithin

Hello bigdelboy , Thank you for your reply.
Yes, By oracle Apps DBA I meant Oracle EBS.
Clearing 1Z0-046 is an option. However, my doubt is will clearing both the exams Admin I and Admin II be of any help without having practical expericnce? The EBS DBA work involves support and patching, cloning, and new node setup etc.
Also, is my performance tuning experience going to help me in any way in the journey forward as a DBA/ EBS DBA?
Thank you for your valuable time.
Regards,
Jithin SarathThe way I read it is this.
People notice you are capable of understanding and performance tuning SQL. And you must have some knowledge of Oracle EBS. And in fact you also have a DBA OCA.
So there is a 98% + chance you can be made into a good Oracle Apps DBA (and core DBA). If I was in their position I'd want you on my team too; this is the way we used to bring on DBA's in the old days before certification and it has a lot of merit still. Okay you can only do limited tasks at first ... but the number of taks you can do will increase dramatically over a number of months.
I would imagine the Oracle Apps DBA will be delighted to have someone on board who can performance tune SQL which sometimes can sometimes seem more like an art than a science. The patching etc can be taught in small doses. If they are a good team they wont try to give you everything at once, they'll get you to learn one procedure at a time.
And remember, if in doubt ask; and if you dont understand ask again. And be safe rather than sorry on actions that could be critial.
If your worried about liinux: Linux Recipes For Oracle Dbas (Apress) might be a good book to read but could be expensive in India
Likewise: (Oracle Applications Dba Field Guide) may suit and even (Rman Recipes For Oracle Database 11 G: A Problem-solution Approach) may have some value if you need to get up to speed quickly in those areas.
These are not perfect but they sometimes consolidate the information neatly; however only buy if you feel they are cheap enough. You may well buy them and feel disappointed (These all happen to be by Apress who seem to have produced a number of good books ... they've also published some rubbish as well)
And go over the 2-day dba examples as well and linux install examples n OTN as well ... they are free compared to the books I mentioned.

Oracle Applications 11i and R12 on Laptop

Hi All,
I have installed Oracle Applications 11.5.10 and R12 on linux RHEL UP7 in Dell Laptop as different users.
Laptop has the H/W configuration is 4GB Ram and Coure2duo 1.7 Processor speed.
I have installed both successfully. But when i am starting the Both applications fine with out any error.
When i am able to accessing the R12 applications getting this error.

when i am shutdown the R11i able to accessing the R12 fine.But where as i am not able to accessing the both at time.its working one only at a time either 11i or R12.
Please let me know if any body faced like issues.
Note: Can we install R11i and R12 on LAPTOP ? above configuration.
Thank you..
Best Regards,
Venkat.

Venkat,
What if you stop the CM on both instances, can you access the R12 page then?
I believe 4 GB of RAM is insufficient to run both instances in addition to the OS, so review the following threads for some tips on how to tune your R12 instance (posted by Michael (mdtaylor)):

Oracle applications performance

Does anyone have any good best practices regarding how to increase
the performance of oracle applications ?
Found this resource
http://www.princetonsoftech.com/html_email/garfield/registerwebinar.asp?id=ggoracleapps
but other than this doesn anyone have other info/links?
Thanks,

Hi, buddy:
you have to be aware that oracle application performance depends on many points, including: oracle database(of course), network, OS(I/O,memory), and last but not least client SQL. while SQL problem may stand up to 50-70% of all.
performance tunning is a open-ended process, it won't turn out to be satisfactory overnight.
good luck!

Oracle Application Management Pack for Siebel 10gR4 is GA

Oracle Application Management Pack for Siebel 10gR4 is now generally available.
Go to this OTN page if you want more information about the product.
http://www.oracle.com/technology/products/oem/prod_focus/app_mgmt.html
You may also download it from OTN to try it out as part of Enterprise Manager 10gR4. We will be demonstrating it at booths D8 and J7 at the Oracle Demoground at Moscone South Hall, at session S291922 at Moscone West L2-2001 on Monday, 11/12 from 3:15 to 4:15 p.m., and at the Siebel Pack Hands-on Lab (S294089) at Marriott Hotel Golden Gate Room B1 on Thursday, 11/15 from 11:30 a.m.-12:30 p.m.
The Siebel Pack is designed to be a complete and integrated management tool for Siebel. Using this management pack, you may get proactive alerts on impending problems on the application, examine run-time statistics to troubleshoot and tune performance, compare configurations across different environments, keep track of configuration changes, proactively enforce configuration policies in order to avoid configuration related problems, monitor and report on service level delivered by the application and performance diagnostics of user and server performance. The pack may be used with other Oracle Enterprise Manager management packs and plug-in’s to achieve end-to-end management of the entire application environment, including both Oracle and non-Oracle databases, operating systems, storage and network devices.
The 10gR4 release of this pack adds integrated Siebel Transaction Diagnostic support using data captured via Siebel Application Response Measurement (SARM) framework. With this tool, you may:
- Analyze request processing for individual user requests
- Analyze CPU and memory consumption of processing requests for different Siebel Server Components
- Visualize SARM metric data graphically
- Compare performance profiles over time
- Create performance reports and share them with your co-worker for collaborative performance diagnostics
The 10gR4 version of this Siebel Transaction Diagnostic tool also adds support for Siebel 7.7 and 7.8 in addition to being compatible with Siebel 8.0. It is fully integrated with Oracle Enterprise Manager, which eliminates the need for separate install and user maintenance, and it runs on all operating system platforms that Oracle Enterprise Manager supports.

Working with the Oracle Enterprise Manager group to integrate closely with their monitoring solutions has been one of the most important advantages of joining the Oracle team. As our customers have started to use CRM more deeply as part of their business processes, CRM has quickly become Mission Critical, with 24/7 uptime requirements. Furthermore, as CRM becomes further integrated into the enterprise, knowing the status and health of the connections to multiple backend systems becomes evermore crucial.
Through our partnership with the Oracle Enterprise Manager, we aim to support true Enterprise-class CRM. We are the only solution out there with over six million live users, and we are leveraging the knowledge gained from those customers in our Enterprise Manager integration. With the real-time monitoring and diagnosis that Oracle Enterprise Manager provides, we simplify the process of managing sophisticated CRM implementations which span organizations and systems. If you have a Siebel implementation with four servers or more, or with integrations to several systems, you owe it to yourself to check out Oracle Enterprise Manager.

Report does not display data in Oracle Applications

I created a custom report and registered the same under Oracle Order Entry. The report uses 1 parameter and whereas everything is registered in Oracle apps. correctly, the report draws a blank upon completion. The only visible thing is the header part.
This report though works fine if run directly from Reports Designer.
Anybody know what specific setting (if required) needs to be made in Oracle Applications? Further in order that you can know the picture, whatever is enclosed in the Repeating Frame does not show up in App. but as pointed earlier works just fine from Reports Designer.
Any help would be greatly appreciated.

I am using a browser (FireFox v2) based InfoView so I guess it is the DHTML viewer.
On the server it is java (Tomcat). The report uses a custom driver (crdb_ado).
Currently all the servers (RAS, page, cache etc) are running under LocalSystem account. I don't understand what a domain account is, is it administrator?
The interesting part is, I was able to upload and run 8 other reports before I experienced this problem. Have I hit some limit?
I appreciate your help. Please share any other ideas/insights on this issue.

Emulating Oracle Applications Environment in BI Publisher Enterprise Server

Hi there,
I think I know what the answer is going to be to this post but for reasons outwith my control I'm trying to understand if there is a workaround to achieve the resultant report output I require.
Background
Oracle E-Business on Demand 11.5.10.2
Oracle BI Publisher 10.1.3.2
My client has Oracle E-Biz on Demand but rather than utilising the integrated XML Publisher engine they have gone down the path of installing BI Publisher Standalone Enterprise Server for their report generation.
Now this works to an extent but I am experiencing problems trying to emulate the setting of an Apps context when I run a report so that I can utilise the Apps security within the Stanalone Enterprise Server. Is this even possible?
Example, basing a data model on PO_VENDOR_SITES (multi-org view) returns 0 (zero) rows but basing it on PO_VENDOR_SITES_ALL returns all rows (for all Orgs).
I can hear you all now yelling, "Use the Oracle Applications XML Publisher" version but in this "On Demand" arena that practice hasn't been adopted so i am raising this post in the hope that someone may be able to suggest a workaround or solution.
Actually, no BI Publisher security model has been adopted and all users use the GUEST account to run reports.
All comments and suggestions are appreciated :-)
Kind Regards,
Gary.

Gary, create a data template and call your own db function to initialise these. The beforeReport trigger will fire and set the enviro prior to the query being executed (as in Reports) Something like this below:
<dataTemplate name="BasicQueryDT" description="Simple query data template" defaultPackage="xxbi_setenviro">
     <dataQuery>
          <sqlStatement name="basicQuery">
               <![CDATA[
select max(last_update_date) today from apps.pa_projects_v]]>
          </sqlStatement>
     </dataQuery>
     <dataTrigger name="beforeReport" source="xxbi_setenviro.before_rep"/>
     <dataStructure>
          <group name="G_Main" source="basicQuery">
               <element name="TheDate" value="today"/>
          </group>
     </dataStructure>
</dataTemplate>

How to integrate Oracle Portal running on Oracle Application Server 10.1.2

I have an Oracle Portal running on a Oracle Application Server 10.1.2.
Portal is responsible ( along with OID ) for the users authentication and authorization.
There is a new JEE application that was developed recently, which the Portal users must have access to.
HOW can I put a link into a page of the Portal, that redirects the portal user to a new browser window displaying my new application?
HOW can this new application, running in a separate weblogic 11g (10.3.5) server, automatically authenticate with the same username/password previously authenticated when the user logged into the portal?
Any ideas?
I´ve already thought in a bunch of ways to do it:
- put a link into the portal with a sessionId, then when opening the new app, it automatically tries to use the same session. How can I configure this session id during the creation of the portal's page? How can I use it from the new app to use the same session?
- put a link into the portal with a userid, then when opening the new app, it automatically tries to authenticate using a different authentication provider configurated in WL, which points to Portal´s OID. In this situation, how can I ensure that the user is already logged in and the session has not timed out?
- Should I use OSSO?
- Should I use OAM?
Any help would be appreciated!
Murilo

Hi Murilo,
A portletized version of your J2EE app would probably have been ideal for your purpose as it would handle both authentication (through SSO) and session information (through Portal framework as the framework can pass session information to the provider/producer). This would require changes to the application however.
Easiest approach would be to use mod_osso to protect your J2EE application. SSO would then handle the authentication for your Portal and your J2EE application.
Thanks,
EJ

Developing for a Oracle Application Server with SSO

Hello there,
I'm developing an application (Java) that will be deployed as a partner application within an Oracle Application Server 10g at my client. This Oracle instance has a SSO already configured, and my app will use this Identity Manager (consuming the cookie). The problem is that at my company we don't have a SSO system configured, not even an Oracle Application Server, just a simple Oracle XE 10g to hold data. So I'm wondering how can I do to develop my application and test it.
I was looking forward to install an OAS and configure an SSO to validate my implementation, but the download link provided by Oracle is broken (http://www.oracle.com/technology/products/ias/index.html). Another alternative that I thought of was to install an OC4J and configure a Java SSO to simulate the behavior of OSSO, and make my app the cookie set by it. But OC4J supports only til Servlet 2.4 and my app is using 2.5...
And to complete, I cannot access my client's environment. I'm supposed to write a Deploying document telling him how to deploy my app and then try to access it through Internet.
Does anyone have an idea of how can I develop and test my app in my company's environment?
Thanks in advance,
Bruno Krebs.

Oracle Application Single Sign-On

Dear All,
We have a requirement that there should be single sign-on for the users to use both the Oracle and non-Oracle Applications. We are using Oracle Application Server 10g at the back end.
How to enable single sign-on. Is there any tool that we need to install.
Pls guide us as we are entirely new to this process.
Regards,
Rajani

Hi,
You need to install and configure Oracle Internet directory and Single Sign On compontents of Oracle Application server 10g in order to have the Single Sign On working with Oracle Applications. After the Oracle Application Server Infrastructure tier installation there is addition integration steps you need to follow to integrate the Single Sign on with Oracle E-business suite. You can use DIP features ( Directory Integration and Provisiotion) to integrate with Third party directory server like Micrososft AD, Sun directory server etc. for Integrating the non oracle based application i think you have to use oracle single sign on API and you need to do bit of coding as well. You can also enble single sign on for database users but this requires advance security option enabled on the Database side and finally you can integrate Single sign on for OS users as well.

Oracle Application Server Release 2 (10.1.2) Deployment Notes question

Hi!
I'm following the Oracle Application Server Release 2 (10.1.2) Deployment Notes (http://download-uk.oracle.com/docs/html/B25947_01/deployment_topics006.htm) for deploying an application, built in Jdeveloper 10.1.3 to AS 10.1.2. I have a question about Configuring JDeveloper to Generate Configuration Files That Are J2EE 1.3-Compliant. Do I need all the files in table 34-3? (http://download-uk.oracle.com/docs/html/B25947_01/deployment_topics006.htm#CIHHBJAI)
I already have some of these files. Can I change the version of existing files or do I need new ones? How can I change the version of existing files?
Here are the headers of some of these files:
web.xml: (Here I probably just change version="2.4" to version="2.3")
<?xml version = '1.0' encoding = 'windows-1250'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee">
orion-application.xml: (Is version="10.0" the version I need to change to "1.2"?)
<?xml version = '1.0' encoding = 'windows-1252'?>

                   xmlns="http://www.oracle.com/technology/oracleas/schema">
data-sources.xml.xml: (This file has only XML version, I don't believe this is the version I need to change)
<?xml version = '1.0' encoding = 'windows-1250'?>I only have these three files from the table in my application. Do I need application.xml and oc4j-connectors.xml too?
Thank you in advance!

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!
