Jdev101304 SU5 - ADF Faces - Web app deployment best practice|configuration

Hi Everybody:
1.- We have several web applications that provides a service/product used for public administration purposes.
2.- the apps are using adf faces adf bc.
2.- All of the apps are participating on javaSSO.
3.- The web apps are deployed in ondemand servers.
4.- We have notice, that with the increase of users on this dates, the sessions created by the middle tier in the database, are staying inactive but never destroyed or removed.
5.- Even when we only sing into the apps using javasso an perform no transacctions (like inserting or deleting something), we query the v$sesisons in the database, and the number of inactive sessions is always increasing, until the server colapse.
So, we want to know, if this is an issue of the configurations made on the Application Module's properties. And we want to know if there are some "best practices" that you could provide us to configure a web application and avoid this behavior.
The only configurations that we found recomended for web apps is set the jbo.locking.mode to optimistic, but this doesn't correct the "increasing inactive sessions" problem.
Please help us to get some documentation or another resource to correct configure our apps.
Thnks in advance.

Fiori App Modification Best Practices?

Hi all,
We are implementing the Approve Travel Expense Fiori app and have encountered the following situation:
The business workflow requires that a rejected expense report have a comment associated with it. In looking at the code the confirmation dialog defaults to allowing the note to be optional. We can address this by setting the noteMandatory property to TRUE (the default is FALSE). But I'm not sure that this is the best solution. When SAP releases an update for the app the modification will be overwritten and someone has to remember to add that property again.
How do other organizations handle situations like this? Is there a best practice recommendation for when a minor code change is needed? Or is there a better way to implement this functionality that I'm not aware of?
Thanks,
Dave

Hi Dave,
SAP provide extensions points for these Fiori Apps, that may be useful to you http://help.sap.com/fiori_bs2013/helpdata/en/a1/611653f5bbef28e10000000a4450e5/content.htm
If you can't use one of the extension points then I think you will need to do what you've already done.

Seeking book recommendation for DBA best practices

Good afternoon,
I've been reading a lot of documentation on Oracle and learning quite a number of commands and different ways of doing things. The problem is knowing the commands is one thing, creating the context where they are appropriate/best is another.
I am looking for a book where the authors share their experience as to "how to do it right" as far as database configuration, backups and all the "details" that are involved in setting up a sound, reliable, robust, manageable and productive environment. A book where the authors would present the "why" do it this way and not the other would be great.
Effectively, I want to gain "experience" vicariously ;)
Thank you for your help,
John.

Hi John,
I am sure that you would like the Scaling book. Reason for that is the snippet of information that you have mentioned about your past work, the book goes into great detail of internals. As I said internals and you do research a lot, bookmark this site http://www.ixora.com.au (Steve Adams) and also get his book,
http://www.amazon.com/Oracle8i-Internal-Services-Latches-Memory/dp/156592598X
Fair warning that lots of stuff has undergone many changes since the book is written and Steve doesn't update the site also now but still, both are a very valuable resource to get into the deep of (some) things and get more clarity.
I am too small to say anything about Jonathan, all I can say that he is just great! His book Practical Oracle 8i is really very good and also, you should bookmark his blog and site, http://jonathanlewis.wordpress.com and www.jlcomp.demon.co.uk. I would strongly suggest to read the co-operative FAQ from his website, http://www.jlcomp.demon.co.uk/faq/ind_faq.html
Yes, its not correct to attribute something as a best practice given the fact that rarely, two environments would be essentially same. That's why I don't like to call anything as a best practice because when I say that in my sessions, it spreads a message that it must be done but actually the answer (mostly) is may (or may not) be . I suggest to know more about Oracle db's work, know what it can do, what are the tools it provides and then use them all wisely :) . Not sure how much I am correct :) .

Developers access to apps database user(Best Practice)?

Hello all,
I'm trying to understand a developers need to have access to the "apps" database user. The arguent can be made that the need is there for all development efforts, but is that really the case? Should all updates/changes by the "apps" user be executed by the apps dba even in the development environment? I'm trying to get a better understanding of how other organizations are set up. Our shop currently allow developers free raign to the apps user, but there are known security risks in doing so with "apps" being such a powerful user of the database environment.
Thanks in advance and any recommendations(Best Practices) will be greatly appreciated.

Hi,
We usually give developers access to APPS schema on the development instances. The access to this schema (and other schemas) is revoked on the UAT/PROD (and other instances where the data is not sanitized). When giving such access we are not much worried about the data as much as we are about the objects, but this is not a big issue as we can recover those objects from other instances. Some organizations do not provide their developers with access to APPS schema on the development instances and all the tasks are done by the Apps DBA team. Another approach would be creating a read only APPS schema (search the forum for details) to allow developers to view the objects/data without bugging the DBAs with such routine tasks.
Thanks,
Hussein

Best practices on number of pipelines in a single project/app to do forging

Hi experts,
I need couple of clarification from you regarding endeca guided search for enterprise application.
1)Say for example,I have a web application iEndecaApp which is created by imitating the jsp reference application. All the necessary presentation api's are present in WEB-INF/lib folder.
1.a) Do I need to configure anything else to run the application?
1.b) I have created the web-app in eclipse . Will I be able to run it from the any thirdparty tomcat server ? If not then where I have to put the war file to successfully run the application?
2)For the above web-app "iEndecaApp" I have created an application named as "MyEndecaApp" using deploymenttemplate. So one generic pipeline is created. I need to integrate 5 different source of data . To be precise
i)CAS data
ii)Database table data
iii)Txt file data
iv)Excel file data
v)XML data.
2.a)So what is the best practice to integrate all the data. Do I need to create 5 different pipeline (each for each data) or I have to integrate all the 5 data's in a single pipeline ?
2.b)If I create 5 different pipeline then all should reside in a single application "MyEndecaApp" or I need to create 5 difference application using deployment template ?
Hope you guys will reply it back soon..... Waiting for your valuable response ..
Regards,
Hoque

Point number 1 is very much possible ie running the jsp ref application from a server of your choice.I havent tried that ever but will draw some light on it once I try.
Point number 2 - You must create 5 record adapters in the same pipeline diagram and then join them with the help of joiner components. The resultant must be fed to the property mapper.
So 1 application, 1 pipeline and all 5 data sources within one application is what should be the ideal case.
And logically also since they all are related data, so must be having some joining conditions and you cant ask 5 different mdex engines to serve you a combined result.
Hope this helps you.
<PS: This is to the best of my knowledge>

Office Web Apps - Best Practice for App Pool Security Account?

Guys,
I am finalising my testing of Office Web Apps, and ready to move onto deploying it to my live farm.
Generally speaking, I put service applications in their own application pool.
Obviously by doing so this has an overhead on memory and processing, however generally speaking it is best practice from a security perspective when using separate accounts.
I have to create 3 new service applications in order to deploy Office Web Apps, in my test environment these are using the Default SharePoint app pool.
Should I create one application pool for all my office web apps with a fresh service account, or does it make no odds from a security perspective to run them in the default app pool?
Cheers,
Conrad
Conrad Goodman MCITP SA / MCTS: WSS3.0 + MOSS2007

i run my OWA under it's own service account (spOWA) and use only one app pool. Just remember that if you go this route, "When
you create a new application pool, you can specify a security account used by the application pool to be either a predefined Network Service account or a managed account. The account must have db_datareader, db_datawriter, and execute permissions for the content
databases and the SharePoint configuration database, and be assigned to the db_owner role for the content databases." (http://technet.microsoft.com/en-us/library/ff431687.aspx)

Best practice to deploy some secret credentials in AIR app

Hi,
Can someone suggest the best practice way to deploy some
secret credentials in an AIR app please?
For example, network connection settings or passwords ?
In my particular case (and since this is only for testing)
I'd like to deploy a password in an AIR app. So is there any way to
effectively deploy an encrypted store with the app ? (hope that
makes sense!)
Tks,
Alex

I think the best practice is not to do it. You can't deploy
an encrypted local
store file to another computer. You could encrypt the
information some other
way, but that just moves the problem. If you have a server,
you could have the
app connect to the server to get the sensitive information
and put it into the
ELS (ideally through HTTPS).

Best practice when using Tangosol with an app server

Hi,
I'm wondering what is the best practice when using Tangosol with an app server (Websphere 6.1 in this case). I've been able to set it up using the resource adapter, tried using distributed transactions and it appears to work as expected - I've also been able to see cache data from another app server instance.
However, it appears that cache data vanishes after a while. I've not yet been able to put my finger on when, but garbage collection is a possibility I've come to suspect.
Data in the cache survives the removal of the EJB, but somewhere later down the line it appear to vanish. I'm not aware of any expiry settings for the cache that would explain this (to the best of my understanding the default is "no expiry"), so GC came to mind. Would this be the explanation?
If that would be the explanation, what would be a better way to keep the cache from being subject to GC - to have a "startup class" in the app server that holds on to the cache object, or would there be other ways? Currently the EJB calls getCacheAdapter, so I guess Bad Things may happen when the EJB is removed...
Best regards,

Hi Gene,
I found the configuration file embedded in coherence.jar. Am I supposed to replace it and re-package coherence.jar?
If I put it elsewhere (in the "classpath") - is there a way I can be sure that it has been found by Coherence (like a message in the standard output stream)? My experience with Websphere is that "classpath" is a rather ...vague concept, we use the J2CA adapter which most probably has a different class loader than the EAR that contains the EJB, and I would rather avoid to do a lot of trial/error corrections to a file just to find that it's not actually been used.
Anyway, at this stage my tests are still focused on distributed transactions/2PC/commit/rollback/recovery, and we're nowhere near 10,000 objects. As a matter of fact, we haven't had more than 1024 objects in these app servers. In the typical scenario where I've seen objects "fade away", there has been only one or two objects in the test data. And they both disappear...
Still confused,
/Per

What are best practice for packaging and deploying j2EE apps to iAS?

We've been running a set of J2EE applications on a pair of iAS SP1b for about a year and it has been quite stable.
Recently however we have had a number of LDAP issues, particularly when registering and unregistering applications (registering ear files sometimes fails 1st time but may work 2nd time). Also We've noticed very occasionally that old versions of classes sometimes find their way onto our machines.
What is considered to be best practice in terms of packaging and deployment, specifically:
1) Packaging - using the deployTool that comes with iAS6 SP1b to package is a big manual task, especially when you have 200+ jsp files. Are people out there using this or are they scripting it with a build tool such as Ant?
2) Deploying an existing application to multiple iAS's. Are you guys unregistering old application then reregistering new application? Are you shutting down iAS whilst doing the deployment?
3) Deploying ear files can take 5 to 10 mins, is this normal?
4) In a clustered scenario where HTTPSession is shared what are the consequences of doing deployments to data stored in session?
thanks in asvance for your replies
Owen

You may want to consider upgrading your application server environment to a newer service pack. There are numerous enhancements involving the deployment tool and run time layout of your application that make clear where you're application is loading its files from.
If you've at a long running application server environment, with lots of deployments under your belt, you might start to notice slow downs in deployment and kjs start time. Generally this is due to garbage collecting in your iAS registry.
You can do several things to resolve this. The most complete solution is to reinstall the application server. This will guarantee a clean ldap registry. Of course you've got to restablish your configurations and redeploy your applications. When done, backup your application server install space with the application server and directory server off. You can use this backup to return to a known configuation at some future time.
For the second method: <B>BE CAREFUL - BACKUP FIRST</B>
There is a more exhaustive solution that involves examining your deployed components to determine the active GUIDS. You then search the NameTrans section of the registry searching for Applogic Servlet *, and Bean * entries that represent your previously deployed components but are represented in the set of deployed GUIDs. Record these older GUIDs, remove them from ClassImp and ClassDef. Finally remove the older entries from NameTrans.
Best practices for deployment depend on your particular environmental needs. Many people utilize ANT as a build tool. In later versions of the application server, complete ANT scripts are included that address compiling, assembly and deployment. Ant 1.4 includes iAS specific targets and general J2EE targets. There are iAS specific targets that can be utilized with the 1.3 version. Specialized build targets are not required however to deploy to iAS.
Newer versions of the deployment tool allow you to specify that JSPs are not to be registered automatically. This can be significant if deployment times lag. Registered JSP's however benefit more fully from the services that iAS offers.
2) In general it is better to undeploy then redeploy. However, if you know that you're not changing GUIDs, recreating an existing application with new GUIDs, or removing registered components, you may avoid the undeploy phase.
If you shut down the KJS processes during deployment you can eliminate some addition workload on the LDAP server which really gets pounded during deployment. This is because the KJS processes detect changes and do registry loads to repopulate their caches. This can happen many times during a deployment and does not provide any benefit.
3) Deploying can be a lengthy process. There have been improvements in that performance from service pack to service pack but unfortunately you wont see dramatic drops in deployment times.
One thing you can do to reduce deployment times is to understand the type of deployment. If you have not manipulated your deployment descriptors in any way, then there is no need to deploy. Simply drop your newer bits in to the run time space of the application server. In later service packs this means exploding the package (ear,war, or jar) in to the appropriate subdirectory of the APPS directory.
4) If you've changed the classes of objects that have been placed in HTTPSession, you may find that you can no longer utilize those objects. For that reason, it is suggested that objects placed in session be kept as simple as possible in order to minimize this effect. In general however, is not a good idea to change a web application during the life span of a session.

Best Practice in maintaining multiple apps and user logins

Hi,
My company is just starting to use APEX, and none of us (the developers) have worked on this before either. It is greatly appreciated if we can get some help here.
We have developed quite a few applications in the same workspace. Now, we are going to setup UAT and PRD environments and also trying to understand what the best practice is to maintain multiple apps and user logins.
Many of you have already worked on APEX environment for sometime, can you please provide some input?
Should we create multiple apps(projects) for one department or should we create one app for one department?
Currently we have created multiple apps for one department, but, we are not sure if a user can login once and be able to access to all the authenticated apps.
Thank you,
LC

LC,
I am not sure how much of this applies to your situation - but I will share what I have done.
I built a single 700+ page application for my department - other areas create separate smaller applications.
The approach I chose is flexible enough to accomdate both.
I built a separate access control application(Control) in its own schema.
We use database authenication fo this app - an oracle account is required.
We prefer to use LDAP for authentication for the user applications.
For users that LDAP is not option - an encrypted password is stored - reset via email.
We use position based security - priviliges are based on job functions.
We have applications, appilcations have roles , roles have access to components(tabs,buttons,unmasked card numbers,etc.)
We have positions that are granted application roles - they inherit access to the role components.
Users have a name, a login, a position, and a site.
We have users on both the East Coast and the West Coast, we use the site in a sys_context
and views to emulate VPD. We also use the role components,sys_contexts and views to mask/unmask
card numbers without rewriting the dependent objects(querys,reports,views,etc.)
The position based security has worked well, when someone moves,
we change the position they are assigned to and they immediately have the privileges they need.
If you are interested I can rpovide more detail.

Best Practice for trimming content in Sharepoint Hosted Apps?

Hey there,
I'm developing a Sharepoint 2013 App that is set to be Sharepoint Hosted. I have a section within the app that I'd like to be Configuration-related, so I would like to only allow certain users or roles to be able to access this content or even see
that it exists (i.e. an Admin button, if you will). What is the best practice for accomplishing this in Sharepoint 2013 Apps? Thusfar, I've been doing everything using jQuery and the REST api and I'm hoping there's a standard within this that I
should be using.
Thanks in advance to anyone who can weigh in here.
Mike

Hi,
According to
this documentation, “You must configure a new name in Domain Name Services (DNS) to host the apps. To help improve security, the domain name should not be a subdomain
of the domain that hosts the SharePoint sites. For example, if the SharePoint sites are at Contoso.com, consider ContosoApps.com instead of App.Contoso.com as the domain name”.
More information:
http://technet.microsoft.com/en-us/library/fp161237(v=office.15)
For production hosting scenarios, you would still have to create a DNS routing strategy within your intranet and optionally configure your firewall.
The link below will show how to create and configure a production environment for apps for SharePoint:

Best practice for the test environment & DBA plan Activities Documents

Dears,,
In our company, we made sizing for hardware.
we have Three environments ( Test/Development , Training , Production ).
But, the test environment servers less than Production environment servers.
My question is:
How to make the best practice for the test environment?
( Is there any recommendations from Oracle related to this , any PDF files help me ............ )
Also please , Can I have a detail document regarding the DBA plan activities?
I appreciate your help and advise
Thanks
Edited by: user4520487 on Mar 3, 2009 11:08 PM

Follow your build document for the same steps you used to build production.
You should know where all your code is. You can use the deployment manager to export your configurations. Export customized files from MDS. Just follow the process again, and you will have a clean instance not containing production data.
It only takes a lot of time if your client is lacking documentation or if you re not familiar with all the parts of the environment. What's 2-3 hours compared to all the issues you will run into if you copy databases or import/export schemas?

Lun Size best practice for UC apps and VMWare?

Hi,
We have UCS manager v2.1 with FI 6248 direct FC attached to NetApp with plenty of storage.
Per following doc, Lun size for UC apps should be 500GB - 1.5TB and 4 to 8 VMs per Lun.
http://docwiki.cisco.com/wiki/UC_Virtualization_Storage_System_Design_Requirements#Best_Practices_for_Storage_Array_LUNs_for_Unified_Communications_Applications
We have four B200M3 blades and 3 to 4 UC apps (CUCM, Unity, UCCX) will be hosted on each blade. May add more VM the blades in the future.
I am thinking four 1 TB Luns and one for each blades. (actually 8 Luns in toal, 4 boot luns for ESXi and 4 for UC apps).
What is the best practice (or common deployment) to create Lun size and design?
Thanks,
Harry

UC apps need low IO，nothing special，Reference vmware LUN design is ok.

Best practice when developing APEX apps and using a SVN repository

Hi experts,
I wanted to get your opinion on best practice regarding how to use SVN and APEX combined.
The idea is basically how to structure and how to save APEX apps the best way in a repository.
I am currently working with a custom SVN structure, not using the default TRUNC/TAGS one : every app has a folder , under every app folder i have PAge number folders, and for each page reports, regions and global objects separated.
This helps me because its more readable then saving the whole page export, its good for small changes and i have a clear overview of every bit and piece.
What is everybody else using or is there a best practice to follow here that i dont know?
Kind regards,
Alex

@tomaugerdotcom
Something like this might help: https://testflightapp.com/
Concevably, you could roll your own internal service if that particular one doesn't suit you. (I don't have any knowledge about how they are doing it, but it shouldn't be hard to figure out since Apple's constraining rules would only allow a few possibilities.)
USB app install and debugging isn't supported on iOS. You have to use wireless.
Another option specifically for multi-touch dev/testing, is to use an Android device.
