Weblogic Tips and Best Practices

- Ensure to take the backup of Config.xml file before making any modifications in weblogic conosle
       MIDDLEWARE/domain/bin/config - Here is the path where you can find config.xml
-  To Start & Stop Weblogic server
        MIDDLEWARE/domain/bin
        ./startWebLogic.sh & - Starts the weblogic server
        ./stopWebLogic.sh   - Stops the weblogic server.

How to Start/Stop Weblogic Server

This post briefly outlines about starting/stopping weblogic server in sevral ways.

Start Weblogic Server in Windows

By default, this directory is MW_HOME\user_projects\domains\DOMAIN_NAME, where DOMAIN_NAME is the root directory of the domain. (The name of this directory is the name of the domain.)

- bin/startWebLogic.cmd (Windows)
- bin\startWebLogic.sh (UNIX and Windows. On Windows, this script supports the MKS and Cygnus BASH UNIX shell emulators.)

Starting Weblogic Server from the Windows Startup Menu

- When you create an Administration Server on a Windows computer, the Configuration Wizard creates a shortcut on the Start Menu for starting the server (User Projects > DOMAIN_NAME > Start Admin Server for WebLogic Domain).

How to start Managed server from weblogic console 

- Login to the Weblogic Admin Console
- Environment->Servers
- Click on the 'server' which you want to start/stop

- Choose 'Configuration' and 'Start/Stop' tabs as shown below
- Select the server and click on 'Start/Stop' button.

- If you encounter any warning message saying 'Node Manager is not running associated' then start the 'Node Manager' as explained below

-MW_HOME\wlsserver_10.3\server\bin
startNodeManager.cmd - If it is on Windows
startNodeManager.sh - If it is on UNIX

Starting Weblogic Server using Node Manager

- "Node Manager is a utility for remote control of WebLogic Server instances. Using Node Manager you can control and monitor Managed Servers and also, start, stop, and restart Administration Servers."
- Start Node Manager
c:\>java weblogic.WLST 
wls:/offline> startNodeManager()
- Start WLST
java weblogic.WLST
- Connect WLST to a Node Manager by entering the nmConnect command.
wls:/offline>nmConnect('username','password','nmHost','nmPort', 'domainName','domainDir','nmType')
Example : nmConnect('weblogic', 'welcome1', 'localhost', '5556','fortuneminds','c:/bea/user_projects/domains/fortuneminds','ssl')
- Start Server
wls:/nm/mydomain>nmServerStatus('serverName') 
- Stop Server
wls:/nm/mydomain>nmKill('serverName') 
Ref : http://docs.oracle.com/cd/E12839_01/web.1111/e13715/manage_servers.htm#WLSTG166


Start the admin server:
              <domain_home>/bin/startWebLogic.sh
Stop the admin server:
             <domain_home>/bin/stopWebLogic.sh
Start the node manager:
            <weblogic_home>/wlserver_10.3/server/bin/startNodeManager.sh
Start a managed server:
           <domain_home>/bin/startManagedWebLogic.sh <managed_server_name> http://<admin_server_host>:<admin_port>
Stop a managed server:
          <domain_home>/bin/stopManagedWebLogic.sh <managed_server_name> http://<admin_server_host>:<admin_port>

How to change the SOA instance state from ? to a valid state

Sometimes I noticed that the SOA suite 11g instance is displayed as Question Mark ("?") which is quite annoying, here is a way to change that setting in the SOA em and capture the proper state of the instance.

·        Right Click on soa-infra domain and select SOA administration > Common properties.

·        Under SOA Infrastructure Common Properties, select Capture Composite Instance State.

How to change the Audit Level for composites in SOA11g ?

It is really useful to turn the audit level in development environment for Testing. SOA11g has 3 levels of audits: Production, Development and Off.

Rightclick on soa-infra domain> SOA Administration> Common properties> and change the audit level to ‘Development’ 

How to display the System Timestamp in XSLT ?

Use the following function to display System Time in XSL with desired format.

<xsl:value-of select="xp20:format-dateTime(xp20:current-dateTime(),'[D01]/[M01]/[Y0001]')"/> - gives the System Date

<xsl:value-of select="xp20:format-dateTime(xp20:current-dateTime(),'  [H01]:[m01]')"/> - gives the System Time

The above XSL functions will display Date Time in the foll. format: 04/10/2009 11:16

How to find the XSLT version that you are using ?

In order to know the XSLT function we are currently working, use the following function:

system-property('xsl:version')

Ex: create a variable and print the XSLT version as follows:

 <xsl:variable name="XSLTVersion">

    <xsl:value-of select="system-property('xsl:version')"/>

  </xsl:variable>

How to put and get files using FTP commands ?

Here are some examples to get/put files on a remote machine from local machine via FTP (File Transfer protocol)

Steps to get the files from remote to local machine

- Open commandprompt from AllPrograms in the computer

- Change directory to which you want to put the files on local machine, using cd command (say cd C:\)

- Now connect to remote machine using ftp command (ftp "hostname"), enter username and password.

- Navigate to the folder from which you want to get the files from remote machine using cd command   Ex: cd /Users

- Say mget* and say y when prompted - This will get all the files to local machine (C:\).

Steps to put the files from local to remote machine

- Open commandprompt from AllPrograms in the computer

- Change directory to which you want to put the files from local machine, using cd command (say cd C:\)

- Now connect to remote machine using ftp command (ftp "hostname"), enter username and password.

- Navigate to the folder to which you want to put the files on remote machine using cd command   Ex: cd /Users

- Say mput* and say y when prompted - This will get all the files to local machine(C:\).

- Say mput m* and this will put all the files starting with 'm'.

How to use String tokenize function in XSLT

Here is an example to use String function: tokenize()

Say the csv has element Role seperated by " ; " and we need to translate using tokenize function:

Roles: Supplier;Vendor;Investor

<Roles>

             <Role>Supplier</Role>

             <Role>Vendor</Role>

             <Role>Investor</Role>

</Roles>

XSL Code:

  <Roles>

                <xsl:call-template name="tokenize">

                  <xsl:with-param name="string"

                                  select="/ns0:Role"/>

                </xsl:call-template>

              </Roles>

  <xsl:template name="tokenize">

    <xsl:param name="separator" select="';'"/>

    <xsl:param name="string"/>

    <xsl:choose>

      <xsl:when test="contains($string,$separator)">

        <Role>

          <xsl:value-of select="substring-before($string,$separator)"/>

        </Role>

        <xsl:call-template name="tokenize">

          <xsl:with-param name="string"

                          select="substring-after($string,$separator)"/>

        </xsl:call-template>

      </xsl:when>

      <xsl:otherwise>

        <Role>

          <xsl:value-of select="$string"/>

        </Role>

      </xsl:otherwise>

    </xsl:choose>

  </xsl:template>

How to use apply-template and call-template in XSLT

How to use <xsl:call-template> and <xsl:apply-template>
How to implement String tokenizer functionality using XSLT

 I will demo an example how to use call-template recursively in XSLT, that is to tokenizea given string based on specified delimiter.

<xsl:call-template> - Using this, we can invoke a template by name of the template

This is how we can define a template with the name as 'tokenize' and which accepts two parameters 

<xsl:template name="tokenize">
    <xsl:param name="separator" select="';'"/>
    <xsl:param name="string"/>
    <xsl:choose>
      <xsl:when test="contains($string,$separator)">
        <ns0:Role>
          <xsl:value-of select="substring-before($string,$separator)"/>
        </ns0:Role>
        <xsl:call-template name="tokenize">
          <xsl:with-param name="string"
                          select="substring-after($string,$separator)"/>
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <ns0:Role>
          <xsl:value-of select="$string"/>
        </ns0:Role>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

- This is how we invoke the template by passing the parameters
                <xsl:call-template name="tokenize">
                  <xsl:with-param name="string"
                                  select="oim:StringWithDelimiter"/>
                </xsl:call-template>

<xsl:apply-template> - Using this we can invoke template by matching a specific element.

This is how we can define a template to invoke using <apply-template>

<xsl:template match="emp:Employee">
   <emp:Name>
      <xsl:value-of select="emp:FirstName"/>
    </emp:Name>
  </xsl:tempate>

How to invoke a template using <apply-template>

<xsl:apply-templates select="/emp:Employee"/>
