Best Practice for serving static files (gif, css, js) from front web server

I am working on optimization of portal performance by moving static files (gif, css, js) to my front web server (apache) for WLP 10 portal application. I end up with moving whole "framework" folder of the portal WebContent to file system served by apache web server (the one which hosts WLS plugin pointing to my WLP cluster). I use <LocationMatch> directives for that:
Alias /portalapp/framework "/somewhere/servedbyapache/docs/framework"
<Directory "/somewhere/servedbyapache/docs/framework">
<FilesMatch "\.(jsp|jspx|layout|shell|theme|xml)$">
Order allow,deny
Deny from all
</FilesMatch>
</Directory>
<LocationMatch "/partalapp(?!/framework)">
SetHandler weblogic-handler
WLCookieName MYPORTAL
</LocationMatch>
So, now browser gets all static files from apache insted of the app server. However, there are several files from bighorn L&F, which are located in the WLP shared lib: skins/bighorn/ window.css, wsrp.css, menu.css, general.css, colors.css; skins/bighorn/borderless/window.css; skeletons/bighorn/js/ util.js, buttons.js; skeleton/bighorn/css/layout.css
I have to merge these files into the project and physically move them into apache served file system to make mentioned above apache configuration works.
However, this approach makes me exposed bunch of framework resources, which I do not to intend to change and they should not be change (only custom.css is the place to make custom changes to the bighorn skin). Which is obviously not very elegant solution. The other approach would be intend to create more elaborate expression for LocationMatch (I am not sure it's entirely possible giving location of these shared resources). More radical move - stop using bighorn and create totally custom L&F (skin, skeleton) - which is quire a lot of work (plus - bighorn is working just fine for us).
I am wondering what is the "Best Practice Approach" approach recommended by Oracle/BEA - giving the fact that I want to serve all static files from my front end apache server instead fo WLS app server.
Thanks,
Oleg.

Oleg,
you might want to have a look at the official WLP performance support pattern (Metalink DocID 761001.1 ) , which contains a section about "Configuring a Fronting Web Server Serving WebLogic Portal 8.1 Static Artifacts ".
It was written for WLP 8.1, but most of the settings / recommendations should also to WLP 10.

Best Practice for Using Static Data in PDPs or Project Plan

Hi There,
I want to make custom reports using PDPs & Project Plan data.
What is the Best Practice for using "Static/Random Data" (which is not available in MS Project 2013 columns) in PDPs & MS Project 2013?
Should I add that data in Custom Field (in MS Project 2013) or make PDPs?
Thanks,

Hi Dale,
I have a Project Level custom field "Supervisor Name" that is used for Project Information.
For the purpose of viewing that "Project Level custom field Data" in
Project views , I have made Task Level custom field
"SupName" and used Formula:
[SupName] = [Supervisor Name]
That shows Supervisor Name in Schedule.aspx
============
Question: I want that Project Level custom field "Supervisor Name" in
My Work views (Tasks.aspx).
The field is enabled in Task.aspx BUT Data is not present / blank column.
How can I get the data in "My Work views" ?

In the Begining it's Flat Files - Best Practice for Getting Flat File Data

I probably should have posed this question here before I delved into writing Java to get data for reports, but better late than never.
Our ERP is written in COBOL. We have a third party ODBC which allows us to access data using a version of SQL. I have several Java sources compiled in my database that access the data and return something relevant. The Java sources are written in a procedural style rather than taking advantage of object oriented programming with attributes and methods.
Now that I am becoming more comfortable with the Java language, I would greatly appreciate any feedback as to best practices for incorporating Java into my database.
My guess is that it would be helpful to model the ERP "tables" with Java classes that would have attributes, which correspond to the fields, and methods to return the attributes in an appropriate way. Does that sound reasonable? If so, is there a way to automate the task of modeling the tables? If not reasonable, what would you recommend?
Thanks,
Gregory

OO is a choice not a mandate. Using Java in a procedural way is certainly not ideal but given that it is existing code I would look more into whether is well written procedural code rather than looking at the lack of OO.

You then implement using whatever means seem expedient in terms of other business constraints to closely model that data model.
It is often the case that there is a strong correlation between data models and tables but certainly in my experience it is rare when there are not other needs driven by the data model (such as how foreign keys and link tables are implemented and used.)

Best practices for cleaning up an old CSS?

We have a legacy help system that we've put into RH 9. Our CSS has a lot of old styles in it. Is there a best practices document somewhere that we can use to learn how to clean up the CSS and remove old styles but still preserve the ones we want?
thanks...

I don't know of any such document but perhaps this will help.
First archive a copy of the CSS as it is now so that you can go back and retrieve anything that you later find you shouldn't have deleted.
Next you should be safe in deleting any styles you see with kadov in them. You will see they are duplicates of another style and were used for the way RoboHelp used to work.
The rest are a bit more difficult. You need to use the multifile find and replace tool to see if they are used in any topic. Then either change them to what you want now or leave them in the CSS.

Best practices for managing jar files

just wondering what anyone's thoughts are on managing jar files. I have read that instead of adding the jar files to your CLASSPATH environment variable, you can just extend the jdk. This is accomplished by inserting the jar files into the C:\jdk1.3.1_01\jre\lib\ext directory. I suspect that if the latter option is truly feasible, it would be preferred to adding entries to the CLASSPATH variable for every jar file you want to use. You could end up with hundreds of entries into the CLASSPATH variable if you have that many jar files in use.
Any thoughts, comments, or links to where I can find any info on this?...
thanks for any information.....

In my company, we use scripts (in UNIX system) to handle this problem. The following scripts can iterate jar files in a given directory:
for i in ${YOUR_LIB_DIR}/*.jar
do
YOUR_CLASSPATH=${YOUR_CLASSPATH}:$i
done
With this simple script, you can use any directory in the same way as the ext\ direcotry (just copy the jar file in it), and you still have the flexibility of maintaining jar files in different directories, say a number of projects.
but i don't know whether .bat/.cmd scripts for windows have the same function.

Best practice for moving portal solution using content db from UAT to PROD

Hi,
Would like to know can we backup the database from UAT env. and restore the same to PROD. if all of my functionality is working fine in UAT env.
I have event receivers[web level features], site collection level features,custom web parts, custom permissions, saved site templates, custom discussion forums etc.
Assuming that I have my custom solution deployed on the Prod. which will activate features for those web parts and my custom application page features.
Is there any issues I can anticipate in PROD.env, if i perform this activity.
or
Is this approach not recommended by Microsoft ? if yes , whats the best approach for deploying portal solution in PROD?
Should I create teh web application, site collections, everything in PROD.from scratch.
any links regarding this approach and the bext practices / helpful info is appreciated.

Thanks Trveor for the reply.
so, I can go ahead and create the web applns, site collections and deploy my web parts, item event receivers, appln pages and my timer jobs in UAT and take the backup of the same and restore it in PROD env.
But, i ahve a doubt here , as I have few site pages created it in my site template and when i take the backupof this web apppln's content db --- [ i think i can take the backup of web appln content db through power shell] ----
will the site pages also be part of this backup?
I had some experience in prev.version of SP, wherein i have few site pages and saved site template I have taken the backup of the web appln and restore it in another farm and associate the restored content db to the
newly created web appln in the targeted farm.
But when I navigated to thsoe restored site pages, it gave me "resource not found /file not found " error.
I had deployed the custom web parts as a custom wsp and added into those site pages.
and it failed to load those web parts UI.
I was not sute whether this happened because of backup or restore from source spfarm to the targeted sp farm .

Best Practice for General User File Server HA/Failover

Hi All,
Looking for some general advice or documentation on recommend approaches to file storage. If you were in our position how would you approach adding more rubustness into our setup?
We currently run a single 2012 R2 VM with around 6TB of user files and data. We deduplicate the volume and use quota's.
We need a solution that provides better redundancy that a single VM. If that VM goes offline how do we maintain user access to the files.
We use DFS to publish file shares to users and machines.
Solutions I have researched with potential draw backs:
Create a guest VM cluster and use a Continuosly Available File Share (not SOFS)
- This would leave us without support for de-duplication. (we get around 50% savings atm and space is tight)
Create a second VM and add it as secondary DFS folder targets, configure replication between the two servers
- Is this the prefered enterprise approach to share avialability? How will hosting user shares (documents etc...) cope in a replication environment.
Note: we have run a physical clustered file server in the past with great results except for the ~5 mins downtime when failover occurs.
Any thoughts on where I should be focusing my efforts?
Thanks

If you care about performance and real failover transparency then guest VM cluster is a way to go (compared to DFS of course). I don't get your point about "no deduplication". You can still use dedupe inside your VM just will have sure you "shrink" the VHDX
from time to time to give away space to host file system. See:

Best practice for auditing a SP 2010 BCS scenario with a SQL Server pooled connection.

I'm using SP 2010 BCS to connect to a SQL Server db. For this, I've used SSS and am passing SQL credentials to take advantage of pooled connections. I'd like to pass the user context (user ID/User name) to the database so that I can do auditing, such as
created by and last modified by. What is the best approach to make this work while still using a pooled connection?
I've thought about modifying the external list forms so that I capture and pass down user context info, however, I'd like not to rely on this in case the external content type is consumed by another consumer such as an Office product, etc.

Hi,
There is no good way to do it.
You can set the created by and modified by columns as input parameters for the create and update operations and using ajax to set values for both of columns.

Best practice for redesigning a website with CSS

I have a site I created in early 2000's in Dreamweaver back in the Macromedia days www.kid-ebooks.com. It is basic HTML using a lot of tables, some flash, etc. I have since created many other sites using CSS and Dreamweaver (Currently on CS5.5) and I now want to do a complete redesign of Kid-ebooks, using CSS. I also however want to keep a lot of existing content, links, etc. I don't know what is the best approach, whether it be to try and apply a CSS to the site, design in parallel and then switch when ready, copy and paste content? What is be recommendation for starting over, but keeping some content?
Thanks,
Dave

I've used this formula with success. Make a back-up site beforehand.
Use Find & Replace > Source code > Tags > to strip out all of the <table> <td> <tr> <font> <background> <bold> and any other deprecated code from the site. Ultimately, you will be left with unstyled content, hyperlinks, & images. Validate code and fix any errors.

Best practice for handling original files once movie is complete?

So I'm taking movies from my Canon S5IS (and other cameras in the past) and making projects in iMovie, sharing in the Media Browser, importing into iDVD, and burning to DVD.
I can't help but wonder if I might need the original footage one day. Do most people keep their original files for future media (replacement for DVD) which I realize would require recreation of the movies that were created in 2008 with iMovie (with title screens, transitions, etc.)? Or do most people delete the originals with the feeling that DVD will be a suitable way to watch home movies for the foreseeable future?
I just can't figure out what to do. I don't want to burn dozens of DVDs of raw footage, only to have keep up with them in a safe deposit box and have to deal with the anxiety of having to recreate movies one day (which is daunting enough now...unbelievably daunting to think about the exponential growth as time progresses).
Hope this make sense. Reading that DVD movies are not suitable for editing due to the codec has made me realize I need to think through this before destroying all these originals as I'm finished with them.
Thanks in advance!
-John

If any of your cams are miniDV, then you simply need to keep the original tapes and tape is still the safest long term archiving solution, when stored properly.
Other cams that use flash memory, hard drives, even DVD cams, do not offer the security that tape does. If you are wanting to save those types of files, the best option would be to store them on one or two external hard drives, bearing in mind those drives could fail anytime. Back up to your back up in that case.
Another nice thing about miniDV cams is that you can export your finished movie back to a tape also, using iMovie HD6, and have safe copies of original and finished material.

Best Practice for Creating JAR File

I have my first java program all done (Yipee!) and I have created the .jar file but I don't think I am really creating it like I should. When I ran it on another machine it had problems because I think it couldn't find all the other classes like the delivered ones.
In my program I have:
import java.io.*;
import java.util.*;
import java.sql.*;
But when I created my JAR file I only specified my manifest, java program and my one class that was created. I am thinking that if I really want this to run on other machines I have to import the java.io.*, java.util.* and java.sql.* in my JAR file as well, is this true?
What is the best way to go about this, only import specific classes instead of the .*? If so I know one class I need to import, java.io.File, what is the best way to find out the other classes?
I commented out all my imports to see how many errors I would get I received 30, I then specified import.java.io.File and I am down to 21.
Thanks!
Ryan Johnson

want this to run on other machines I have to import the java.io.*, java.util.* and java.sql.* in my JAR file as well, is this true?No. The core classes shuld be present in the Java environment on the target machine.
You have to ship only your classes and eventually the third party libraries.

Best practice for using static methods

When i want to call a static method, should i call:
1) classInstance.staticMethod()
or should i call
2) ClassName.staticMethod()??
is the first style bad programming practice?

dubwai: which compiler?I had assumed that this was what the JLS specifies, but intsead, it goes into length how to make the runtime environment treat calls to static methods on instances as if they were static calls on the variable's type.
However, I imagine anyone creating a compiler would go ahead and compile calls to static methods on instances to static calls on the variable's type instead of going through the effort of making the runtime environment treat calls to static methods on instances as if they were static calls on the variable's type.
But of course, it is concievable that somone didn't in their compiler. I doubt it but it is possible. Sun does compile calls to static methods on instances to static calls on the variable's type:
public class Garbage
    public static void main(String[] args)
        Garbage g = null;
        method();
        g.method();
    public static void method()
        System.out.println("method");
public class playground.Garbage extends java.lang.Object {
    public playground.Garbage();
    public static void main(java.lang.String[]);
    public static void method();
Method playground.Garbage()
   0 aload_0
   1 invokespecial #1 <Method java.lang.Object()>
   4 return
Method void main(java.lang.String[])
   0 aconst_null
   1 astore_1
   2 invokestatic #3 <Method void method()>
   5 invokestatic #3 <Method void method()>
   8 return
Method void method()
   0 getstatic #4 <Field java.io.PrintStream out>
   3 ldc #5 <String "method">
   5 invokevirtual #6 <Method void println(java.lang.String)>
   8 return

What is the best practice for removing IMAPMail files from Thunderbird Profiles folder?

I removed some old IMAP accounts via Account Settings > Remove Account. But I see that the IMAP files (Inbox, Drafts, Sent, .msf, .sbd, etc.) for the accounts are still in /Library/Thunderbird/Profiles/*.default/ImapMail. What is the proper way to delete these old account files?

When the corresponding account has been removed, there's no association to Thunderbird anymore. The files are kept on purpose in case an account has been deleted by error.
You should be certain that you don't need those files anymore though.
It probably wouldn't hurt to create a backup of your profile prior to deleting the files either.

Best practice for how to access a set of wsdl and xsd files

I've recently beeing poking around with the Oracle ESB, which requires a bunch of wsdl and xsd files from HOME/bpel/system/xmllib. What is the best practice for including these files in a BPEL project? It seems like a bad idea to copy all these files into every project that uses the ESB, especially if there are quite a few consumers of the bus. Is there a way I can reference this directory from the project so that the files can just stay in a common place for all the projects that use them?
Bret

Hi,
I created a project (JDeveloper) with local xsd-files and tried to delete and recreate them in the structure pane with references to a version on the application server. After reopening the project I deployed it successfully to the bpel server. The process is working fine, but in the structure pane there is no information about any of the xsds anymore and the payload in the variables there is an exception (problem building schema).
How does bpel know where to look for the xsd-files and how does the mapping still work?
This cannot be the way to do it correctly. Do I have a chance to rework an existing project or do I have to rebuild it from scratch in order to have all the references right?
Thanks for any clue.

Best Practices for Accessing the Configuration data Modelled as XML File in

Hi,
I refer the couple of blof posts/Forum threads on How to model and access the Configuration data as XML inside OSB.
One of the easiest and way is to
Re: OSB: What is best practice for reading configuration information
Another could be
Uploading XML data as .xq file (Creating .xq file copy paste all the Configuration as XML )
I need expert answers for following.
1] I have .xsd file which is representing the Configuration data. Structure of XSD is
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue</Config>
<FrameworkConfig>
2] As my project will move from one env to another the property-value will change according to the Environment...
For Dev:
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Dev</Config>
<FrameworkConfig>
For Stage :
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Stage</Config>
<FrameworkConfig>
3] Let say I create the following Folder structure to store the Configuration file specific for dev/stage/prod instance
OSB Project Folder
|
|---Dev
|
|--Dev_Config_file.xml
|
|---Stage
|
|--Stahe_Config_file.xml
|
|---Prod
|
|-Prod_Config_file.xml
4] I need a way to load these property file as xml element/variable inside OSb message flow.?? I can't use XPath function fn:doc("URL") coz I don't know exact path of XMl on deployed server.
5] Also I need to lookup/model the value which will specify the current server type(Dev/Stage/prod) on which OSB MF is running. Let say any construct which will act as a Global configuration and can be acccessible inside the OSb message flow. If I get the vaalue for the Global variable as Dev means I will load the xml config file under the Dev Directory @runtime containing key value pair for Dev environment.
6] This Re: OSB: What is best practice for reading configuration information
suggest the designing of the web application which will serve the xml file over the http protocol and getting the contents into variable (which in turn can be used in OSB message flow). Can we address this problem without creating the extra Project and adding the Dependencies? I read configuration file approach too..but the sample configuration file doesn't show entry of .xml file as resources
Hope I am clear...I really appreciate your comments and suggestion..

If you can enforce some sort of naming convention for the transport endpoint for this proxy service across the environments, where the environment name is part of the endpoint you may able to retrieve it from $inbound in the message pipeline.
eg. http://osb_host/service/prod/service1 ==> Prod and http://osb_host/service/prod/service2 ==> stage , then i think $inbound/ctx:transport/ctx:uri can give you /service/prod/service1 or /service/stage/service1 and applying appropriate xpath functions you will be able to extract the environment name.
Chk this link for details on $inbound/ctx:transport : http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1080822
