Best practice for application module for scalability

if i compare application module with forms 6i runtime session.(correct me if i wrong)
In forms 6i, we create for single form for purchase entry. in which we select table like po , po_item, item_master, customer master
also single form for sales entry. in which we select table like sales , sales_item, item_master, customer master, po , po_item
So my question is. in jdeveloper , we planning to make separate jsp page and applicaiton module for purchase entry,
separare jsp page and application module for sales.
is it ok.
or
what is the best practice in this senario.?? ( or in scalability senario)
if i made one single application module for whole application (let say 300 entity's(tables)) will performance of my app server degrade.

Best practices to reduce downtime for Database releases(rolling changes)

Hi,
What are best practices to reduce downtime for database releases on 10.2.0.3? What DB changes can be rolling and what can't?
Thanks in advance.
Regards,
RJiv.

I would be very dubious about any sort of universal "best practices" here. Realistically, your practices need to be tailored to the application and the environment.
You can invest a lot of time, energy, and resources into minimizing downtime if that is the only goal. But you'll generally pay for that goal in terms of developer and admin time and effort, environmental complexity, etc. And you generally need to architect your application with rolling upgrades in mind, which necessitates potentially large amounts of redesign to existing applications. It may be perfectly acceptable to go full-bore into minimizing downtime if you are running Amazon.com and any downtime is unacceptable. Most organizations, however, need to balance downtime against other needs.
For example, you could radically minimize downtime by having a second active database, configuring Streams to replicate changes between the two master databases, and configure the middle tier environment so that you can point different middle tier servers against one or the other database. When you want to upgrade, you point all the middle tier servers against database A other than 1 that lives on a special URL. You upgrade database B (making sure to deal with the Streams replication environment properly depending on requirements) and do the smoke test against the special URL. When you determine that everything works, you configure all the app servers to point at B and have Streams replication process configured to replicate changes from the old data model to the new data model), upgrade B, repeat the smoke test, and then return the middle tier environment to the normal state of balancing between databases.
This lets you upgrade with 0 downtime. But you've got to license another primary database. And configure Streams. And write the replication code to propagate the changes on B during the time you're smoke testing A. And you need the middle tier infrastructure in place. And you're obviously going to be involving more admins than you would for a simpler deploy where you take things down, reboot, and bring things up. The test plan becomes more complicated as well since you need to practice this sort of thing in lower environments.

Best practice to define length for varchar field of table in sql server

What is best practice to define length for a varchar field in table
where field suppose Remarks By Person varchar(max) or varchar(4000)
Could it affect on optimization in future????
experts Reply Must ...
Dilip Patil..

Hi Dilip,
Varchar(n/max) is a variable-length, non-unicode character data. N defines the string length and can be a value from 1 through 8,000. Max indicates that the maximum storage size is 2^31-1 bytes (2 GB). The storage size is the actual length of the data entered
+ 2 bytes. We always use varchar when the sizes of the column data entries vary considerably. While if the filed data size might exceed 8,000 bytes in some way, we should use varchar(max).
So the conclusion is just like Uri said, use varchar(max) or varchar(4000) is depends on how much characters we are going to store.
The following document about varchar in SQL Server is for your reference:

Best practice identifying ERT modules with SAP / IS-Utilities

Hi everybody,
I'm looking for the best practice identifying ERT modules with SAP / IS-Utilities (electricity).
Here's the physical device set up :
The ERT modules are internal to the electricity meter. They're integrated into a multi purpose electronic circuit. So they can't be remove physically as a separate device.
The ERT modules are used to transmit data from the meter to a radio frequency receiver (handheld or drive-by). The main data that is transmitted is the consumption reading. So the receiver stores the ERT module number and the reading value.
They may be one or more ERT modules in a single meter, and each ERT module transmit his own specific consumption reading (energy reading, demand reading, etc...).
Each ERT module has is own manufacturer number.
My issue is :
To find a way to identify in IS-U the ERT module within the meter's register group (or somewhere else???) in order to relate each register to his ERT module number.
The purpose of all this is to create reading orders with the ERT module number following for each register.
This way we can match, using a unique key, each reading order and his corresponding reading value uploaded from the radio frequency receiver (handheld or drive-by).
Thanks for your help and ideas on best practice.

Hi,
1) The system (application) environment of BI (what is integrated in it - e. g. within the portal, there is a storage for unstructured information like documents or virtual rooms for collaboration between departments - and what does it make)
Document management from RSA1 transaction of BI helps to attach any unstructured documents at specific level in BI.
2) How does development in BI works (development environment, coding, debugging, building, deployment and test) and what is used stronger (ABAP or ABAP OO)? Here, I don't mean how to write ABAP or ABAP OO programs, only the infrastructure from development to transport to a target system
BI has got a separate tool and GUI to perform all the Extract, Transform and load related activities. ABAP is part of BI but you don't need much extensive ABAP learning. Basic ABAP is sufficient to write routines and extractors.
3) How is a BI system to configure as default after installation?
May be a BASIS person can help you out here about the configuration but this is not the job of BI person.
4) Good guides (e/books) to learn ABAP and ABAP OO (as far as possible oriented on the practive)
You can search for SAM Series learn ABAP in 24 days book. This book is sufficient to learn the ABAP required for working in BI.
But except ABAP you will have to completly learn the BI system to work efficiently.

Best practice for application help for a custom screen?

Hi,
The system is Netweaver 7.0 SP 15 with e-recruiting .
We have some custom SAP GUI transactions and have written Word documents with screen prints and explanations. I would like to make the procedure document accessible from the custom transaction or at least provide custom help text that includes a link to the full documents.
Can anyone help me out with options and best practices for providing customized application help for custom SAP GUI transactions?
Thanks,
Margaret

Hello Margaret,
sorry I though you might be still in a design or proof of concept phase where the decision for the technology is still adjustable.
If the implementation is already done things change of course. The standard in-system documentation is surely not fitting your needs as including screenshots won't work well.
I would solve the task the following way:
I'd make a web or pdf document out of the word document and put it on a web ressource - as you run e-recruiting you have probably the possibility for that.
I would then just put a button into the transaction an open a web container to show the document.
I am not sure if this solution really qualifies as "best practise" but SAP does the same if you call the Help for application in the help menue. This is implemented in function module SAPGUIHC_OPEN_HELP_CENTER. I'd just copy it, throw out what I do not need and hard code the url to call.
Perhaps someone could offer a better solution but I think this works a t least without exxagerated costs.
Kind Regards
Roman

Looking for best practice on application scope beans

Hey â€“ a portal newbie here. Iâ€™ve got some application scope beans that need to be initialized on startup. First thought was to create a servlet that would set the bean. Then I saw the GlobalApp setting, but I think that looks like it is more session scope than applicationâ€¦ Looking to be corrected here if I am wrong.
Is there a place where these type of things traditionally happen? Read only, so no cluster worries (I think) Using WLP 8.1 SP4 and looking for best practices. Thanks for the help!

To support "code sharing" you need an integrated source code control system. Several options are out there but CVS (https://www.cvshome.org/) is a nice choice, and it's completely free and it runs on Windows, Linux, and most UNIX variants.
Your next decision is on IDE and application server. These are usually from a single "source". For instance, you can choose Oracle's JDeveloper and Deploy to Oracle Application Server; or go with free NetBeans IDE and Jakarta Tomcat; or IBM's WebSphere and their application server. Selection of IDE and AppServer will likely result in heated debates.

Best Practices or Project Template for Rep/Version

I have installed the Repository 6i (3) and created the users successfully, even though it has taken a lot of effort to make sure each step is correct.
However, on setting up the workareas and importing the project files, I have been trying back and force to figure out where things go, and who has what access.
Is there something like a best practice or a project template for setting up a basic repository/version control system, that provides
1. the repository structure,
2. corresponding file system structure (for different developers, build manager, etc)
3. access grants, and
4. work scenarios, etc.
The Technet demos and white papaers are either too high-level (basic), or too individual function oriented. I can't get a clear picture of the whole thing, since there are so many concepts and elements that don't easily go together.
Considering that I am a decent DBA and developer, it has taken me 2 weeks, and I am still not ready to sign up other developers to use this thing. How do you expect any small development teams to ever use it? It's one thing to design it to be scalable and all-possible, it's another to make it easily usable. I have been suggested to use MS VSS. The only reason I am still trying Ora-Rep is its promise to directly support Designer and Oracle objects.

Andy,
I have worked extensively with the Repository over the last year and a half. I have collected some of my experiences and the derived guidelines on using the Repository in real life in a number of papers that I will be presenting at ODTUG 2001, next week in San Diego. If you happen to be there (see www.odtug.com), come and see me and we could talk through your specific situation. If you are not and you are interested in those papers, drop me an Email and I could send them to you (they probably will also become available on OTN right after the ODTUG conference).
best regards,
Lucas

Best practices on using OLM for sign-off on compliance policies?

We are working on a project to build a parent/child learning object that will include four compliance policies and a "test" to sign off acceptance of these policies as a condition of employment. Has anyone implemented something like this? If so - can you please share some best practices around this type of implementation. Our plan is to build a learning certification.
We are also interesting in looking into how to automate the assignment of the learning certification to all new hires. Any info here would also be appreciated.
Thanks - Juli

We use 11.5.10j...One thing I would recommend is creating an introductory module as child object to the certification, and a concluding module as child object as well.
In the learning objects I have done where a parent/child relationship exists, the introductory module is important for several reasons, including instructing learners about how to expand the OLM Player outline on the left to move to the next module (in 11.5.10j, at least, it doesn't expand automatically so the general population is not going to understand they need to expand and move to the next module. You might try to tell people to do that independently of the course but we've found it's best to put as part of the course.) The introductory module also includes things like objectives, expected duration, completion requirements, audience, etc.
As for the concluding module, I include a concluding module to instruct people that they have reached the end and provide a screenshot of the OLM Player "Home" button to instruct them to return to the OLM home page. Using the OLM "Home" button circumvents issues with popup blockers suppressing the passing of completion information back to OLM when exiting using the IE exit button and is generally a cleaner way to exit the course. Again, instructions might be provided independent of the learning object but most will not pay attention to those. There is a patch to test for the presence of popup blockers and alert the user so that there might be less need for a concluding module to do this but we have not been able to implement this yet due to problems caused after it was applied.

Archiving Best Practices / How To Guide for Oracle 10g - need urgently

Hi,
I apologize if this is a silly question. But i need a step by step archiving guide for Oracle 10g and cannot find any reference document. I am in a rather remote part of S.E. Asia & can't seem to find DBA's with the requisite experience to do the job properly. I have had 1 database lock up this week at a big telecoms provider and another one at a major bank is about to go. I can easily add LUNS & re-structure mirrors etc at the Unix level [ i am a Unix engineer ]
but i know that is not the long run solution. I am sure the 2 databases i am concerned about have never been archived properly.
This is the sort of thing DBA's must do all the time. Can someone point me to the proper documentation so i can do a proper job and archive a few years data out of these databases. I do not want to do a hack job. At least i can clone the databases and practise on the clones first before i actually do production.
-thanks very much

I'm not so sure this is a general database question, as it would be specific to an application and implementation, and as the technology has changed, the database options to support it has too.
So for example, if you have bought the partitioning option, there may be some sensible procedure for partitioning off older data.
Things may depend on whether you are talking about an OLTP, a DW, a DSS, or mixed systems.
DBA's do it all the time because the requirements are different everywhere. Simply deleting a lot of data after copying the old data to another table (as some older systems do) may just wind up giving you performance problems scanning swiss-cheesed data.
Some places may not archive at all, if they've separated out OLTP from reporting. If all the OLTP stuff is accessed through indices, all the older stuff just sits there. The reporting DB may only have what is needed to be reported on, or be on a standby db where range scans are sufficient to ignore old data. There there's exadata, which has it's own strengths.
Best Practices have to be on similar enough systems, otherwise they are a self-contradiction.
Get yourself someone who understands your requirements and can evaluate the actual problem. No apology needed, it is not a silly question. But what is silly is assuming what the problem is with no evidence.

Best Practice setting up NICs for Hyper V 2008 r2

I am looking at some suggestions for best practice for setting up a hyper V 2008 r2 at a remote location with 5 nics, one for managment vlan and other 4 on the data vlan. This server will host 2 virtual machines, one is a DC and the other
is a member local DHCP server. The server is setup now with one nic on the management Vlan and the other nic's set to get there ip from the local dhcp server on on the host. We have the virtual networks setup in Hyper V to
point to each of the nics using the "external connection". The virtual servers 'DHCP and AD" have there own ip set within them. Issues we are seeing, when the site looses external connections for a while they cannot get ip
addresses from the local dhcp server anymore.
1. NIC on management Vlan -- IP Static -- Physical host
2. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- virtual server DHCP
3. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- Virtual server domain controller
4. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- extra
5. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- extra
Thanks in advance

Looks like you may be over complicating things here. More and more of the recommendations from Microsoft at this point would be to create a Logical Switch and then layer on Logical Networks for your management layers, but here is what I would do for
you simple remote office.
Management NIC: Looks good (Teaming would be better, but only if you had 2 different switching to protect against link failures at the switch level. Doesn't seem relevant in this case however.
NIC for Data Network VLAN: I would use one NIC in your case if you can have the ability to Trunk multiple VLANs at the switch level to the NIC. That way you are setting the VLAN on the VMs NIC that you want to access and your
Virtual Switch configuration is very simple. On this virtual switch however, I would uncheck IPv4 and IPv6. There is no need to give this NIC an address as you are just passing traffic through them from the VMs that are marked with VLAN tags. Again,
if you have multiple physical switches in the building teaming could be an option, but probably adds more complexity than is necessary for a small office.
Even if you keep your Virtual Switches linked to separate NICs unchecking IPv4 and IPv6 makes sense.
Disable all the other NICs
Beyond that, check your routing. Can you ping between all hosts when there is not interruption? What DHCP server are they getting there addresses on normally? Where are your name resolution servers (DNS, WINS)?
No silver bullet here, but maybe a step in the right direction.

Best Practice : Creating Custom Renderer for Standard Component

I've been reading the docs and a few threads about Custom Renderers. The best practice seems to be to create a Custom Component where you need a Custom Renderer. Is this the case?
See [this post|http://forums.sun.com/thread.jspa?forumID=427&threadID=520422]
I've created several Custom Renderers to override the HTML provided by the Standard Components, however I can't see the benefit in also creating a Custom Component when the behaviour of the standard component is just fine.
Thanks,
Damian.

It all depends on what you are trying to accomplish. Generally speaking if all you need is for the user interface output to be changed then a renderer will work just fine. A new component is usually made in order to provide some fundamental change in server side functionality not related to the user interface. - Ponderator

Best Practice Advice - Using ARD for Inventorying System Resources Info

Hello All,
I hope this is the place I can post a question like this. If not please direct me if there is another location for a topic of this nature.
We are in the process of utilizing ARD reporting for all the Macs in our district (3500 +/- a few here and there). I am looking for advice and would like some best practices ideas for a project like this. ANY and ALL advice is welcome. Scheduling reports, utilizing a task server as opposed to the Admin workstation, etc. I figured I could always learn from those with experience rather than trying to reinvent the wheel. Thanks for your time.

hey, i am also intrested in any tips. we are gearing up to use ARD for all of our macs current and future.
i am having a hard time with entering the user/pass for each machine, is there and eaiser way to do so? we dont have nearly as many macs running as you do but its still a pain to do each one over and over. any hints? or am i doing it wrong?
thanks
