Best Practice type question

Our environment currently has 1 Connection factory defined per JMS Module. We also have multiple queues per JMS Module.
          In other J2EE AppServer environments I have worked in, we defined 1 connection factory per queue.
          Can someone explain if there a best practice, or at least a good reason for doing one over the other.
          The environment here is new enough that we can change how things are set up if it makes sense to do so.

My two cents: A CF allows configuration of client load-balancing behavior, flow-control behavior, default QOS, etc. I think its good to have one or more CFs configured per module, as presumably all destinations in the module are related in some way, and they therefore likely all require basically the same client behavior. If you have very few destinations, then it might help to have one CF per destination, but this places a bit more burden on the administrator to configure the extra CFs in the first place, and on everyone to remember which CF is best for communicating with which destination.

Best Practices needed -- question regarding global support success stories

My customer has a series of Go Lives scheduled throughout the year and is now concerned about an October EAI (Europe, Asia, International) go live. They wish to discuss the benefits of separating a European go Live from an Asia/International go live in terms of support capabilities and best practices. The European business is definitely larger and more important than the Asia/International business and the split would allow more targeted focus on Europe. My customer does not have a large number of resources to spare and is starting to think that supporting the combined go live may be too much (i.e., too much risk to the businesses) to handle.
The question for SAP is regarding success stories and best practices.
From a global perspective, do we recommend this split? Do most of our global customers split a go live in Europe from a go live in Asia/International (which is Australia, etc.). Can I reference any of these customers? If the EAI go live is not split, what is absolutely necessary for success, etc, etc? For example, if a core team member plus local support is required in each location, then this may not be possible with the resources they have u2026u2026..
I would appreciate any insights/best practices/success stories/or u201Cwaru201D stories you might be aware of.
Thank you in advance and best regards,
Barbara

Hi, this is purely based on customer requirement.
I have a friend in an Organization which went live in 38 centers at the same time.
With the latest technologies in networking, distances does not make any difference.
The Organization where I currently work in, has global business locations. In my current organization the go live was in phases. Here they went live in the region where the business was maximum first because this region was their largest and most important as far as revenue was concerned. Then after stabilizing this region, a group of consultants went to the rest of the regions for the go live in that region.
Both the companies referred above are successfully into SAP and are leading partners with SAP. Unfortunately I am not authorized to give you the names of the Organizations as a reference for you as you requested.
But in your case if you have shortage of manpower, you can do it in phases by first going live in the European Market and then in phases you can go live in the other regions.
Warm Regards

Real time logging: best practices and questions ?

I've 4 couples of DS 5.2p6 in MMR mode on Windows 2003.
Each server is configured with the default setting of "nsslapd-accesslog-logbuffering" enabled, and the log files are stored on a local file system, then later centrally archived thanks to a log sender daemon.
I've now a requirement from a monitoring tool (used to establish correlations/links/events between applications) to provide the directory
server access logs in real time.
At a first glance, each directory generates about 1,1 Mb of access log per second.
1)
I'd like to know if there're known best practices / experiences in such a case.
2)
Also, should I upgrade my DS servers to benefit from any log management related feature ? Should I think about using an external disk
sub-sytem (SAN, NAS ....) ?
3)
In DS 5.2, what's the default access logbuffering policy : is there a maximum buffer size and/or time limit before flushing to disk ? Is it configurable ?

Usually log-buffering should be enabled. I don't know of any customers who turn it off. Even if you do, I guess it should be after careful evaluation in your environment. AFAIK, there is no configurable limit for buffer size or time limit before it is committed to disk
Regarding faster disks, I had the bright idea that you could creating a ramdisk and set the logs to go there instead of disk. Let's say the ramdisk is 2gb max in size and you receive about 1MB/sec in writes. Say max-log-size is 30MB. You can schedule a job to run every minute that copies over the newly rotated file(s) from ramdisk to your filesystem and then send it over to logs HQ. If the server does crash, you'll lose upto a minute of logs. Of course, the data disappears after reboot, so you'll need to manage that as well. Sounds like fun to try but may not be practical.

I should ask, how realtime should this log correlation be?

Eclipse / Workshop dev/production best practice environment question.

I'm trying to setup an ODSI development and production environment. After a bit of trial and error and support from the group here (ok, Mike, thanks again) I've been able to connect to Web Service and Relational database sources and such. My Windows 2003 server has 2 GB of RAM. With Admin domain, Managed Server, and Eclipse running I'm in the 2.4GB range. I'd love to move the Eclipse bit off of the server, develop dataspaces there, and publish them to the remote server. When I add the Remote Server in Eclipse and try to add a new data service I get "Dataspace projects cannot be deployed to a remote domain" error message.
So, is the best practice to run everything locally (admin server, Eclipse/Workshop). Get everything working and then configure the same JDBC (or whatever) connections on the production server and deploy the locally created dataspace to the production box using the Eclipse that's installed on the server? I've read some posts/articles about a scripting capability that can perhaps do the configuration and deployment but I'm really in the baby steps mode and probably need the UI for now.
Thanks in advance for the advice.

you'll want 4GB.

Manage Portal data ? best practice type thing

Hello,
I am looking how best do set up a Portal System on Production, in particular a
good process to back-up and re-create an Portal systems.
I list some possibilities below. Does anyone know if this is how it is typically
done ? Does this cover all data which should be backed up / migrated ?
thanks!
1- 'Entitlements' data. As far as I know, this is stored in the embedded LDAP.
Can this be extracted ?
2- DataSynch data.
DataSynch web application.
extract with ftp-like command
upload as jar file
3- Users and Groups.
Export to a dat file. (Suddenly I forget how to do this, though think I saw it
somewhere).

Okey, and then using a RFC call from the webdynpro application to fetch data from the sap database?
This answered my question:

Database best practice theoretical question

Hi Forums
I wasn't sure which forum to post this under- general non-specific Database question.
I have a client server database app, which is working well with a single network client currently. I need to implement some kind of database record locking scheme to avoid concurrency problems. I've worked on these kind of apps. before, but never one this complicated. Obviously I've scourged the web looking into this, but found not too much good reference material.
I was thinking of making some kind of class with several lists- one for each table that requires locking having record locks whilst transactions are occuring. Then having clients request locks on records, then release locks when they are finished.
I'm wondering if client requests a lock..then crashes without releasing locks. Should there be a timeout set to enable server release record? Should the client be polling the server to show its still working on the record? This sounds a mess to me!
If anyone can direct me to some good reference material on this I would appreciate it.

EDT* OK now I feel silly! Theres a great article on [Wiki |http://en.wikipedia.org/wiki/Concurrency_control] showing some often used methods.

thanks for the response, yes there are many columns that violate 3NF and that is why the column count is so high.
Regarding the partition question, by better I meant by using "interval" the partitions could be created automatically at the specified interval instead of having to create them manually.The key is to understand the logic behind these tables and columns. Why it was designed like this, if it's business requirement then 200 some columns are not bad, if it's design flaw 20 columns could be too much. It's not necessarily always good to have strict 3NF design, sometime for various reason you can denormalize the tables to get better performance.
As to partitioning Q, you have to do the rolling window (drop/add partition as time goes by) type of partitioning scheme manually so far.

Best practice - a question on how best do somethin...

Hi,
The problem: To be able to geotag my location, adding a pin and some text to mark a particular point of interest at that location and then be able to navigate back to it in future. Ovi maps is not available in-browser which was my first choice (where you can add a POI) and I cannot seem to do this in Ovi Maps for N900.
(Of course the ideal for me would be to have desktop widget which I could press and it would mark my GPS location on a map with space for a comment but I know this isn't a wish list :-)
Could I please ask people their approach to this problem, what software they use and how.
Many thanks
Tom

Would be a nice feature. Not sure exactly what's coming in future updates or when Meego hits the servers. But someone over at Maemo.org forums may be able to suggest a couple of apps that are available or being developed.

Best Practice for Significant Amounts of Data

This is basically a best-practice/concept question and it spans both Xcelsius & Excel functions:
I am working on a dashboard for the US Military to report on some basic financial transactions that happen on bases around the globe. These transactions fall into four categories, so my aggregation is as follows:
Year,Month,Country,Base,Category (data is Transaction Count and Total Amount)
This is a rather high level of aggregation, and it takes about 20 million transactions and aggregates them into about 6000 rows of data for a two year period.
I would like to allow the users to select a Category and a country and see a chart which summarizes transactions for that country ( X-axis for Month, Y-axis Transaction Count or Amount ). I would like each series on this chart to represent a Base.
My problem is that 6000 rows still appears to be too many rows for an Xcelsius dashboard to handle. I have followed the Concatenated Key approach and used SUMIF to populate a matrix with the data for use in the Chart. This matrix would have Bases for row headings (only those within the selected country) and the Column Headings would be Month. The data would be COUNT. (I also need the same matrix with Dollar Amounts as the data).
In Excel this matrix works fine and seems to be very fast. The problem is with Xcelsius. I have imported the Spreadsheet, but have NOT even created the chart yet and Xcelsius is CHOKING (and crashing). I changed Max Rows to 7000 to accommodate the data. I placed a simple combo box and a grid on the Canvas u2013 BUT NO CHART yet u2013 and the dashboard takes forever to generate and is REALLY slow to react to a simple change in the Combo Box.
So, I guess this brings up a few questions:
1)     Am I doing something wrong and did I miss something that would prevent this problem?
2)     If this is standard Xcelsius behavior, what are the Best Practices to solve the problem?
a.     Do I have to create 50 different Data Ranges in order to improve performance (i.e. Each Country-Category would have a separate range)?
b.     Would it even work if it had that many data ranges in it?
c.     Do you aggregate it as a crosstab (Months as Column headings) and insert that crosstabbed data into Excel.
d.     Other ideas that Iu2019m missing?
FYI: These dashboards will be exported to PDF and distributed. They will not be connected to a server or data source.
Any thoughts or guidance would be appreciated.
Thanks,
David

Unicode Migration using National Characterset data types - Best Practice ?

I know that Oracle discourages the use of the national characterset and national characterset data types(NCHAR, NVARCHAR) but that is the route my company has decide to take and I would like to know what is the best practice regarding this specifically in relation to stored procedures.
The database schema is being converted by changing all CHAR, VARCHAR and CLOB data types to NCHAR, NVARCHAR and NCLOB data types respectively and I would appreciate any suggestions regarding the changes that need to be made to stored procedures and if there are any hard and fast rules that need to be followed.
Specific questions that I have are :
1. Do CHAR and VARCHAR parameters need to be changed to NCHAR and NVARCHAR types ?
2. Do CHAR and VARCHAR variables need to be changed to NCHAR and NVARCHAR types ?
3. Do string literals need to be prefixed with 'N' in all cases ? e.g.
in variable assignments - v_module_name := N'ABCD'
in variable comparisons - IF v_sp_access_mode = N'DL'
in calls to other procedures passing string parameters - proc_xyz(v_module_name, N'String Parameter')
in database column comparisons - WHERE COLUMN_XYZ = N'ABCD'
If anybody has been through a similar exercise, please share your experience and point out any additional changes that may be required in other areas.
Database details are as follows and the application is written in COBOL and this is also being changed to be Unicode compliant:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16

##1. while doing a test convertion I discovered that VARCHAR paramaters need to be changed to NVARCHAR2 and not VARCHAR2, same for VARCHAR variables.
VARCHAR columns/parameters/variables should not by used as Oracle reserves the right to change their semantics in the future. You should use VARCHAR2/NVARCHAR2.
##3. Not sure I understand, are you saying that unicode columns(NVARCHAR2, NCHAR) in the database will only be able to store character strings made up from WE8MSWIN1252 characters ?
No, I meant literals. You cannot include non-WE8MSWIN1252 characters into a literal. Actually, you can include them under certain conditions but they will be transformed to an escaped form. See also the UNISTR function.
## Reason given for going down this route is that our application works with SQL Server and Oracle and this was the best option
## to keep the code/schemas consistent between the two databases
First, you have to keep two sets of scripts anyway because syntax of DDL is different between SQL Server and Oracle. There is therefore little benefit of just keeping the data type names the same while so many things need to be different. If I designed your system, I would use a DB-agnostic object repository and a script generator to produce either SQL Server or Oracle scripts with the appropriate data types or at least I would use some placeholder syntax to replace placeholders with appropriate data types per target system in the application installer.
## I don't know if it is possible to create a database in SQL Server with a Unicode characterset/collation like you can in Oracle, that would have been the better option.
I am not an SQL Server expert but I think VARCHAR data types are restricted to Windows ANSI code pages and those do not include Unicode.

EDI - 753Routing Request and 754 Routing Instructions transactions- what SAP ECC6 EDI output type, msg type, msg code, basis idoc is best practice to generate the idoc?

One of our Trading Partner wishes to implement the 753 Routing Request and 754 Routing Instructions. Can anyone give me best practice answer the following Questions? We are on SAP ECC6 R3
What Application? i.e. V2, V7?
What output condition to use? i..e. LALE, LAT2, SEDI????
What Message type? i.e SHPADV?
What Basic Idoc Type? i.e SHPMNT05?
What Message Code? i.e. SHPM?
What Process Code? i.e. SHPM??
What Function Module? i.e. IDOC_OUTPUT_SHPMNT??
Does the SAP Transpotation Module have to be configured for this to be implemented?
Your comments are greatly appreciated, we have until Nov 1 to be compliant?

Good Morning,
While I did not get any responses from my question, yes, I was able to determine what needed to be configured. I hope the below will help you: This is for SAP ECC6
The output application for the 753 Routing Request is "V7"
The output type is "SEDI"
Transmission medium is "6"
The Basic Idoc type is "Shipmnt05"
when setting up your Partner Profile (WE20) add:Message Partner Role "SP" with Message type "SHPADV', Message coed "753", Basic Type "SHPMNT05", Message Control add Application "V7", Message type "SEDI", Process Code "SHPM".
also http://scn.sap.com/thread/698368 pages 14 and 15 were helpful.
I have not configured the Inbound 754. For now the inbound 754 Routing Instructions will be emailed to our traffic department.
Thank you,
Have a great day,
jane

Informatica and Essbase Best Practice questions

We now have the Informatica adapter for Essbase installed and working. We have been able to get Informatica to upload data successfully. Now I have a few questions that I have not been able to find answers to in any documentation or forums for Informatica or Essbase. I have submitted these same questions to the Informatica Support but thought I would also post the questions here to see if many folks are using Informatica against Essbase.
We are using:
Informatica 8.6.1 (Linux)
Essbase 11.1.1.3 (Windows 2003)
1) I can see in Informtica that when we load data to Essbase (Target) it gives me the option to run a calc script AFTER it loads the data. However, if I need to run a Calc script BEFORE the load to Essbase (Target) what is the best practice? The work around I have found was to add the same session twice and for the 1st instance select the option to 'ONLY RUN THE CALC SCRIPT' on the mapping tab. The problem with this is the log shows that it will still run the query against the Source tables. This will impact run times and double to querying against the Source database. What is the Best Practice and proper way to build the workflow to Run a Calc Script BEFORE the load?
2)Since you do not see the list of Calc Scripts for Essbase in Informatica (you have to manually type the Calc name), If I want to run the 'Default' calc for Essbase what is the syntax to run the 'Default' Calc Script? Tried 'Default' but didn't seem to work.
3)I have other tasks in Essbase I want to do before actually having Informatica load the data. I would like to run the MAXL commands via a Command task. What is the Best Practice for doing this and the syntax to run MAXL commands in a Command Task in Informatica? I previously had Shell scripts built on the Informatica server that would be kicked off within Informatica, but we are trying to move away from shell scripts and instead have the scripting codes IN the workflows/sessions to make it easier to review the code and follow the logic, rather than having to find the scripts and open each of them.
Any assistance you have with the two products working together I would GREATLY appreciate it!

AS i know addUser(User user){ ... } is much more useful for several reasons:
1.Its object oriented
2.its easy to write , because if Object has many parameters its very painful to write method with comma seperated parameters

Question - Best practice data source for Vs2008 and Crystal Reports 2008

I have posted a question here
CR2008 using data from .NET data provider (ADO.NET DATASET from a .DLL)
but think that perhaps I need general community advise on best practice with data sources.
In Crystal reports I can choose the data source location from any number of connection types, eg ado.net(xml), com, oledb, odbc.
Now in regard to the post, the reports have all been created in Crxi 6.3, upgraded to Crystal XI and now Im using the latest and greatest. I wrote the Crystal Reports 6.3/ XI reports back in the day to do the following: The Reports use a function from COM Object which returns an ADO recordset which is then consumed fine.
So I don't want to rewrite all these reports, of which there are many.
I would like to know if any developers are actually using .NET Class libraries to return ADO.NET datasets via the method call or if you are connecting directly to XML data via whatever source ( disk, web service, http request etc).
I have not been able to eliminate the problem listed in the post mentioned above, which is that the Crystal Report is calling the .NET class library method twice before displaying the data. I have confirmed this by debugging the class lib.
So any guidance or tips is appreciated.
Thanks

This is already being discuss in one of your other threads. Let's close this one out and concentrate on the one I've already replied to.

Best Practices Question: How to send error message to SSHR web page.

Best Practices Question: How to send error message to SSHR web page from custom PL\SQL procedure called by SSHR workflow.
For the Manager Self-Service application we’ve copied various workflows which were modified to meet business needs. Part of this exercise was creating custom PL\SQL Package Procedures that would gather details on the WF using them on custom notification sent by the WF.
What I’m looking for is if/when the PL\SQL procedure errors, how does one send an failure message back and display it on the SS Page?
Writing information into a log or table at the database level works for trouble-shooting, but we’re looking for something that will provide the end-user with an intelligent message that the workflow has failed.
Thanks ahead of time for your responses.
Rich

We have implemented the same kind of requirement long back.
We have defined our PL/SQL procedures with two OUT parameters
1) Result Type (S:Success, E:Error)
2) Result Message
In the PL/SQL procedure we always use below construct when we want to raise any message
hr_utility.set_message(APPL_NO, 'FND_MESSAGE_NAME');
hr_utility.raise_error;
In Exception block we write below( in successful case we just set the p_result_flag := 'S';)
EXCEPTION
WHEN APP_EXCEPTION.APPLICATION_EXCEPTION THEN
p_result_flag := 'E';
p_result_message := hr_utility.get_message;
WHEN OTHERS THEN
p_result_flag := 'E';
p_result_message := hr_utility.get_message;
fnd_message.set_name('PER','FFU10_GENERAL_ORACLE_ERROR');
fnd_message.set_token('2',substr(sqlerrm,1,200));
fnd_msg_pub.add;
p_result_message := fnd_msg_pub.get_detail;
After executing the PL/SQL in java
We have written some thing similar to
orclStmt.execute();
OAExceptionUtils.checkErrors (txn);
String resultFlag = orclStmt.getString(provide the resultflag bind no);
if ("E".equalsIgnoreCase(resultFlag)){
String resultMessage = orclStmt.getString(provide the resultMessage bind no);
orclStmt.close();
throw new OAException(resultMessage, OAException.ERROR);
It safely shows the message to the user with all the data in the page.
We have been using this construct for a long time for all our projects. They are all working as expected.
Regards,
Peddi.

New to ColdFusion - Question regarding best practice

Hello there.
I have been programming in Java/C#/PHP for the past two years or so, and as of late have really taken a liking to ColdFusion.
The question that I have is around the actual seperation of code and if there are any best practices that are preached using this language. While I was learning Java, I was taught that it's best to have several layers in your code; example: Front end (JSPs or ASP) -> Business Objects -> Daos -> Database. All of the code that I have written using these three languages have followed this simple structure, for the most part.
As I dive deeper into ColdFusion, most of the examples that I have seen from vetrans of this language don't really incorporate much seperation. And I'm not referring to the simple "here's what this function does" type of examples online where most of the code is written in one file. I've been able to see projects that have been created with this language.
I work with a couple developers who have been writing in ColdFusion for a few years and posed this question to them as well. Their response was something to the affect of, "I'm not sure if there are any best practices for this, but it doesn't really seem like there's much of an issue making calls like this".
I have searched online for any type of best practices or discussions around this and haven't seen much of anything.
I do still consider myself somewhat of a noobling when it comes to programming, but matters of best practice are important to me for any language that I learn more about.
Thanks for the help.

Frameworks for Web Applications can require alot of overhead, more than you might normally need programming ColdFusion, I have worked with Frameworks, including Fusebox, what I discovered is when handing a project over to a different developer, it took them over a month before they were able to fully understand the Fusebox framework and then program it comfortably. I decided to not use Fusebox on other projects for this reason.
For maintainability sometimes its better to not use a framework, while there are a number of ColdFusion developers, those that know the Fusebox framework are in the minority. When using a framework, you always have to consider the amount of time to learn it and succesfuly implement it. Alot of it depends on how much of your code you want to reuse. One thing you have to consider, is if you need to make a change to the web application, how many files will you have to modify? Sometimes its more files with a framework than if you just write code without a framework.
While working on a website for Electronic Component sourcing, I encountered this dynamic several times.

Best Practices for NCS/PI Server and Application Monitoring question

Hello,
I am deploying a virtual instance of Cisco Prime Infrastructure 1.2 (1.2.1.012) on an ESX infrastructure. This is being deployed in an enterprise enviroment. I have questions around the best practices for moniotring this appliance. I am looking to monitor application failures (services down, db issues) and "hardware" (I understand this is a virtual machine, but statistics on the filesystem and CPU/Memory is good).
Firstly, I have enabled via the CLI the snmp-server and set the SNMP trap host destination. I have created a notification receiver for the SNMP traps inside the NCS GUI and enabled the "System" type alarm. This type includes alarms like NCS_DOWN and PI database is down. I am trying to understand what the difference between enabling SNMP-SERVER HOST via the CLI and setting the Notification destination inthe GUI is? Also how can I generate a NCS_DOWN alarm in my lab. Doing NCS stop does not generate any alarms. I have not been able to find much information on how to generate this as a test.
Secondly, how and which processes should I be monitoring from the Management Station? I cannot easily identify the main NCS procsses from the output of ps -ef when logged in the shell as root.
Thanks guys!

1.) What is the cost of having the scope in a <jsp:useBean> tag set to 'session'? I am aware that there are a list of scopes like page, application, etc. and that if i use 'session' my variable will live for as long as that session is alive. (did i get this right?). You should rather look to the functional requirements instead of costs. If the bean need to be session scoped (e.g. maintain the logged in user), then do it so. If it just need to be request scoped (e.g. single page form data), then keep it request scoped.
2.)If the JSP Page where i use that <useBean> is to be accessed hundred of times a day, will it compensate my server resources? Right now i am using the Sun Glassfish Server.It will certainly eat resources. Just supply enough CPU speed and memory to a server. You cannot expect that a webserver running at a Pentium 500MHz with 256MB of memory can flawlessly serve 100 simultaneous users at the same second. But you may expect that it can serve 100 users per 24 hour.
3.) Can you suggest best practice in memory management given the architecture i described above?Just write code so that it doesn't unnecessarily eat memory. Only allocate memory if your application need to do so. You should rather let the hardware depend on the application requirements, not to let the application depend on the hardware specs.
4.)Also, I have implemented connection pooling in my architecture, but my application is to be used by thousands of clients everyday.. Can the Sun Glassfish Server take care of that or will I have to purchase a powerful sever?Glassfish is just an application server software, it is not server hardware. Your concerns are rather hardware related.
