Patching strategy for Production environment

Hi all,
Can anyone share their patch strategy specially for production environment?? We have production environment and we are planning to patch our databases using PSU pacthes with no downtime. Our production environment has standby. We have one option that we can make standby to primary. Is there any other options that we can use??? Also we are not using Grid control.
Thanks

Hi there,
In 11gR2 onwards it is possible to patch without downtime using a physical standby database (converts to transient logical standby). Please look at the document below. There is a script on Metalink as well which makes this all much easier.

Is vmware supported for production environment ?

Hi All,
Is vmware supported for production environment ?
Thanks
Sunny

All,
I'm glad someone has outlined the clear support statement that has existed for sometime between VMware - SAP. For those of you still running on Oracle, here is some good news:
Wording towards SAP Customers requesting support:
"Oracle, VMware and SAP are working collaboratively to ensure support for SAP customers that use VMware virtualization for SAP solutions running Oracle DB. Functional tests are currently being performed to verify supportability of the SAP&Oracle stack. Details will be made available in SAP note 1173954 u201CSupport of Oracle for VMwareu201D after tests have been completed. It is expected that in Q1 2010, ESX 3.5 and later releases including vSphere 4 will be supported by Oracle and SAP according to Oracleu2019s metalink note 249212."
There is no reason why x86 platform today cannot run the most demanding workloads on VMware vSphere in a production environment. But has noted earlier, don't get hung up on "production" - you have heaps of TestDev, SolMan TestDev, sandboxes, gateways, application servers etc that should immediately by put into a VM - once you are comfortable with your solution in-house, I'm sure you will move production instances into a VM as well.
Below are some great resources for you to use in your quest to virtualize SAP on VMware:

Batch Strategy for Production orders

Hi All,
I just wanted to find out that what are plant specific settings while implementing the batch determination strategy for Production orders? I have configured Batch determination and batch check for Plant A and Plant B. However, in Plant B, the system does not pick the batch automatically while in Plant A, it does. I have checked almost all the batch settings in SPRO but could not find any differences between plant A and plant B. Can anyone please guide me on this>?

Hi,
Pls. check in SPRO > Logistics general > Specify batch level and activate status management.
SPRO > logistics general > Batch number assignment > activate internal batech number assignment

Patch strategy for ECC6 in SAP NW2004s environment

Hi Experts,
Our SAPNW04s landscape consists of ECC6, BI 7.0, EP7.0 , SRM, XI, Solution Manager systems. We are drafting patch upgrade strategy for the ECC6 system & have 2 options:
Option 1: Apply patches only in ECC6 & not in other components.
Option 2: Patch ECC6 together with other components like SRM, BI, EP etc.
Option 2 will make things complicated but for Option 1 below are the 2 concerns/questions raised:
1. Option 1 will lead to doing UAT twice for Business Processes which have a tight integration with ECC6, for ex. UAT for data extraction needs to be done after applying patches both in the ECC6 & the BI systems. This will lead to arrange for more user resources.
2. Due to the tight integration between ECC6 & other components applying patches alone in the ECC6 might lead to other systems like BI, EP,SRM, XI etc at a lower level & they might not be able to connect to ECC6 or work properly with ECC6.
Can somebody share how they are managing the ECC6 patches upgrade in a big NW2004s environment with other components present, are the ECC6 patches done standalone & other systems like EP, BI follow their own different time schedules for patching or ECC6, BI, EP are recommended to be done together.
Are there any best practices recommendations from SAP on the same?. Can somebody share the blueprint or any strategy document they are using.
Thanks,
Abhishek

Hi Abhishek,
For the reasons you outline in 2, it is recommended to patch entire business scenarios (i.e. business processess that are coupled integrated across systems) together. Rather than go into a full discussin here, I recommend you see my paper [How To Design a SAP NetWeaver - Based System Landscape |https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/50a9952d-15cc-2a10-84a9-fd9184f35366].

Oracle Installation for Production Environment.

Hi All,
We need to install Oracle in our production environment.
But since there is no DBA in our project, we need to do it by ourself.
I was just wondering what all steps and cautions I need to take to install it.
I was told just double click on Setup.exe :-) and that would suffice.
I am pretty sure its not that easy, atleast for a production environment.
We might need to set some params, may be.
We are at present using Oracle 10g Rel 1.
Any help/suggestion would be highly appreciated.
Thanks in Advance,
Tanuja

Well, it does more complicate than a double click of setup.exe, especially for a production database.
It's not only about the installation, also think about how do you want to create your database, the storage configuration, database configuration, and backup/recover strategy etc.
For installation, make sure you follow Oracle installation guide,
http://download.oracle.com/docs/html/B10130_02/toc.htm
And there are many other document here

Best Practice for Production environment

Hello everyone,
can someone share the best practice for a production environment? or is there a SAP standard best practice to follow in a Production landscape?
i understand there are Best practices available for Implementation , Migration and upgrade. But, i was unable to find one for productive landscape
thanks.

Hi Siva,
What best practise are you looking for ? If you can be specific on your question we could provide appropriate response.
From my basis experience some of the best practices.
1) Productive landscape should have high availability to business. For this you may setup DR or HA or both.
2) It should have backup configured for which restore has been already tested
3) It should have all the monitoring setup viz application, OS and DB
4) Productive client should not be modifiable
5) Users in Production landscape should have appropriate authorization based on SOD. There should not be any SOD conflicts
6) Transport to Production should be highly controlled. Any transport to Production should be moved only with appropriate Change Board approvals.
7) Relevant Database and OS security parameters should be tested before golive and enabled
8) Pre-Golive , Post Golive should have been performed on Production system
9) EWA should be configured atleast for Production system
10) Production system availability using DR should have been tested
Hope this helps.
Regards,
Deepak Kori

Container classes generation for production environment

You can run the WebLogic EJB compiler on the JAR file before you deploy the beans,
or you can let WebLogic Server run the compiler for you at deployment time.
I have to release :
- an ear, containing 1 ejb and other stuff
- a client-jar (delegate, remote, home), that will be included in another ear (client
application of our ejb).
Both the ear will be deployed on the same wl instance (6.1sp2) (production environment).
For a production environment, which are the pros and contras ?
(not considering deploy time differences on wlserver, of course).
Which is the best practice ? Is it suggested to release the ear with the container
classes already generated (run ejbc before) or delegate the generation to weblogic
server ?
Thanks in advance
Sergi

Is standalone OC4J scalable for production environment

Hi,
Can our team use an OC4J standalone (a cluster perhaps) to deliver Web applications on a production environment?
The Web app comprises JSPs and Servlets only at the moment, in future we are considering EJBs and other J2EE components.
Will standalone OC4J scale well and is performance good enough for real world applications?
Thank you
Llies Meridja

OC4J standalone is the exact same code that is packaged inside of Oracle9iAS so will have the same characteristics of Oracle9iAS. The benchmarks that Oracle markets with the ECPerf and SpecJAppServer is same thing ... so you should have no issues with performance etc.
You might have seen that we recently released a Java Edition of Oracle9iAS, which focuses primarily on the Java features rather than the extended features like Portal, Wireless etc. If you look at this URL, you will see the feature set comparison of this minimal Java version compared to the other versions:
http://www.oracle.com/ip/deploy/ias/index.html?pkgsum.html
Further, as I understand it, as long as you license one of the Java Edition, Standard Edition or Enterprise Edition, you will be supported running the corresponding instance stand-alone instance of OC4J if you want to work outside of the out-of-the-box framework which Oracle9iAS provides for OC4J instances to run in.

Topology for production environment

this question is related to production environment deployment and clustering.
we have 1 physical server where we have webcenter domain. this domain has 1 admin server and 1 managed server (custom web center portal managed server).
our plan is to deploy our application on this managed server.
this is no clustered environment and not recommended (no failover, no load balancing).
what shall we do?
shall we create another managed server (custom web center portal managed server) and deploy our application on these 2 managed servers? there will be a load balancer in front to take care of transferring request to both the servers...
what's your suggestions?
please note that i know specific answer will depend on NFR (user load, performance etc) but i am looking for general guidance and reference around same like -
how many managed server recommended?
what kind of topology recommended for web center application?
etc
thanks.

I'd recommend you to start with this document: http://docs.oracle.com/cd/E11035_01/wls100/cluster/overview.html as a lot of this question is related to Weblogic clustering than WebCenter.
Note that whilst clustering has many pros, it has also few cons; among those:
- you might require additional hardware/software, or used components (like filesystem) will have to have features that you don't need in a non-clustered environment
- though small, scaling does consume some resources (I've heard that WebCenter Content takes 1-2% of Solaris, but up-to 25% on Windows Servers!)
- it's always at least a bit more expensive
Therefore, you should not go for a cluster, because it's cool, but because you have damn good reasons for that (that you didn't mention!), stemming from SLAs, or requirements for Disaster Recovery.
You write that you have just one physical server, so you already have one potential single point of failure.
I think I've heard that Weblogic Server itself is capable of self-recovery; this means, that a server may go down (you will lose all the current sessions), but is capable of auto-recovery. If your users survive that from time to time they will lose uncommitted work, then maybe a need for clustering (HA) won't be that strong (you might also go just for tuning your Weblogic Server).
On the other hand, where clustering might be necessary, if you need to scale, especially, if you need cloud-like increase/decrease of resources. I doubt it is possible to say up-front how many servers is recommended, but you may tune this later - whilst going from 1 node to 2 is relatively a big leap, going from 2 to 3, or 3 to 4 is then quite easy.
Either way, I'd recommend you to be in sync with your app server admin.thanks jiri. this was helpful.
while i agree that any architectural decision should be justifiable to requirements but as far as my experience goes clustering is basic thing in any production environment... in case 1 managed server goes down, other can still serve requests...
i'll read link provided by you and ask specific questions if any...
thanks.

Install 11gR2 on Linux 6 with ASM for production environment ?

Hi Experts
Plz I hope someone could help me, I am planning to Install Oracle 11g R2(11.2.0.3)
on Oracle Linux 6 with ASM for a production environment.
My doubt is: Is it a stable combination ? someone has experience working with this version ? is there some Oracle documents to support this implementation on Production ?
I have been installing and working with 11g R2 on Oracle Linux 5 (5.7,5.8) with ASM for some time and I didn’t have problems, it’s very stable combination
My situation is this: Our client insist on use Oracle Linux 6 on a new Oracle implementation, even when we told her Oracle Linux 5 its Very stable, so that’s why I am asking for some advice, because it’s a production environment 7x24.
Thank you for your time and advice

License required for Production Environment

Want to know what kind of license would be required to deploy Crystal Reports on a Production Environment with a Java based Web Application.
At present, we have been looking at Jasper Reports and we are trying to understand what kind of cost will be involved in using Crystal Reports in a Production Environment.

Patching Strategy for CRS and ASM homes

I'm fairly new to RAC/ASM and haven't performed any patch set upgrades yet. Back in the simple days when I wanted to apply a patch set to a database, say from 10.2.0.4 to 10.2.0.5, I would create a brand new Oracle home ahead of time and apply the patch set to it. I'd name my homes like this:
/opt/oracle/product/10.2.0.4/db1
/opt/oracle/product/10.2.0.5/db1
During the maintenance window I would change /etc/oratab to point the database to the new 10.2.0.5 and complete the database upgrade scripts. The advantages of this strategy:
1 - Less risk installing software as nothing uses the new home yet. If something goes wrong in the install, no big deal. Research the problem and try again without being under the stress of a defined maintenance window.
2 - No need to backup old home for back-out purposes.
3 - Less time required for database to be down during actual patch window since Oracle Installer does not need to run.
Now with CRS and ASM, is there a way to pre-stage a new home for those, but not have them "active" to the node until later during the maintenance window?
For ASM, it seems like it would be possible to treat the same way as database and simply update ASM SID in /etc/oratab
+ASM1:/opt/oracle/product/10.2.0.5/asm1
but I'm not totally confident in that as I'm afraid the CRS home may already have references to the ASM home in the cluster registry.
For CRS, it seems like the home is pretty well hard-wired into the node startup scripts and installing a brand new CRS home will probably disrupt the running CRS home.
Any thoughts about this?

Starting with 11.2 for Grid Infrastructure only "out-of-place" patchset upgrades are supported.

Any thoughts about this?As of 11gR2 the ASM is part of the Grid Infrastructure, therefore it is running from the same home and not recommended to separate them. (although you can do that)
By the way, what is your upgrade path? It could be easier to answer your questions if we knew that as there has been a quite a few enhancements and changes in the upgrade/patching process from 10g to 11g. (even between 11gR1 and 11gR2)

Strategy for product display in multi -multi categories??

Hi guys,
My client wants many many variations of product catalogs... too many to do effectively by creating catalogs for each one. I'm trying to figure out the best way of doing this and I realize there is a potential problem with keywords and tags. As I understand it, I have keywords and have created "tags" in Custom (column) 1 . I realize you can create a featured list by calling a tag, but here's the problem... All Cartier watches are tagged with watch, but not all watches are Cartier. To give you the idea of the complexity of this layout, here's a sample of some of the current catalogs I'm moving over to BC:
Watches (36)
All (36)
Breguet Ladies (1)
Breitling (1)
Cartier Ladies (5)
Cartier Mens(5)
Omega (1)
Panerai (1)
Patek Phillipe(1)
Rolex Watches Ladies (5)
Rolex Watches Modern (11)
Rolex Watches Vintage (5)
Cartier Jewelry (4)
All (4)
Bracelets (1)
Earrings (1)
Rings (2)
Watches (10)
Now multiply this by several brands, like Tiffany and the like, and you get many many crossovers.
So I have a couple of questions: what is the safest way to enter tags and keywords for a featured list, e.g.: with or without commas???
Rather than create a separate catalog for each of these many options, is there a way to create a display catalog from keywords or tags? I started creating a featured list, but IF I use Rings, for example, it calls up all rings and not just rings that are Cartier rings or Tiffany rings.
In addition, he has an entirely separate catalog that is of archived items for custom jewelry already sold as examples and not for sale, and they too have rings, bracelets, etc...
If I could call up featured items in ONLY a single catalog and exclude all rings from other catalogs, it might work... But I'm kind of stumped as how to best do this..
TIA,
Jeff
PS... this was so much easier in php creating dynamic catalogs I could control...

Have you got all the RH7 patches installed? There was a problem fixed in 7.0.1 that sounds similar to what you are experiencing. If you haven't patched your version yet, I'd recommend getting all of the patches.
See snippet 14 on Peter Grainge's site for the blank topic issue, and snippets 23, 31 and 34 for what's in the patches.
http://www.grainge.org/pages/authoring/rh7/using_rh7.htm
Also note issue #20 in the 7.0.1 patch notes - if you are affected by this, I believe you'll have to fix it manually, unless you can afford to go back to a pre-upgraded version of your project and upgrade once you've installed all the patches. If you can't go back, which is likely if you've all been working on the project, I think it should just be a case of find and replace across your HTML files - you should be able to do a search on the forums for it, or maybe Peter or Rick will chime in with additional information if it is a problem for you.

Can I use forms and reports 6I runtime for production environment?

I have a doubt.
I know if i use or install developer (forms and reports 6I) both, runtime and builder, I do require a license.
But If I buy the standard edition license for database (in production or deployment), and I wanna use the runtimes (from forms and reports) only as runtime not to modify or develop anything, is it possible? just to download it or install it in RUNTIME mode?
Is it possible and legal?
Thanks

Can I download that developer and install both forms and report runtime (yes only runtime) to access a licensed standard edition database? The problem is, you can't download that version any more! All download links to Forms version earlier that 10g R2 have been removed from Oracle's web site. You might still be able to download Forms 6i from My Oracle Support, but this requires a paid license agreement with Oracle to access My Oracle Support (formerly Metalink).
So, if you already have a copy of Oracle Developer Forms and Reports 6i then all you need to do is contact your local Oracle Sales Representative to get an official answer to your licensing question. If you don't have a copy of Forms 6i, then you are pretty much out of luck unless you know someone who has a copy!

I'm searching the good requirements about the storage in an prod environment to support efficiently a SSAS tabular or multidimensional solutions, in terms of capacity, rate, I/O, etc.
Any suggests to me, please?
Thanks

There a super nice video from Marco Russo and a pptx about it here:
