Update ports in existing profiles

Use the updatePorts.ant script to change ports in an installed profile.

Each profile template has its own updatePorts.ant script.

The updatePorts.ant script for application server profiles is in...

WAS_HOME/profileTemplates/template_name/actions

To use the script, we have to identify which profile to update. You should only run this script if the profile is unfederated and if the configuration is the same structure as it was when the profile was created. For example, this script is ideal for changing ports for an unfederated application server profile after you created the profile but before you altered its configuration. For all other situations, use the techniques described in "Setting port numbers kept in serverindex.xml using scripting".

Use the following procedure to become familiar with using the updatePorts.ant script. Each step is an exercise that results in reassigning ports using a particular method that the updatePorts.ant script supports.

Look at steps for all of the operating systems mentioned. The differences are mainly in the extension of the script file and the direction of the directory delimiters. For example, Linux shell scripts (*.sh) and other commands require a ./ before the command to tell the operating system that the command is in the current working directory.

Procedure

• Assign nonconflicting ports to the AppSrv01 profile.

  The ANT script assigns nonconflicting ports by default. No special arguments are needed. Identify the fully qualified directory paths, profile name, unique node name, and unique cell name. Then issue the command.

  1. Create the Java properties file encoded in ISO8859-1 file encoding, to assign nonconflicting port values to the application server profile.

     For this example, assume that the system is a Linux operating system and that you create the following /TMP/was_props/appserver.props properties file.

     WAS_HOME=/opt/IBM/WebSphere/AppServer
     was.install.root=/opt/IBM/WebSphere/AppServer
     profileName=AppSrv01
     profilePath=/opt/IBM/WebSphere/AppServer/profiles/AppSrv01
     templatePath=/opt/IBM/WebSphere/AppServer/profileTemplates/default
     nodeName=appserver_node01
     cellName=appserver_cell01
     hostName=myserver.ibm.com
     
     

  2. Open a command shell window.
  3. Change directories to the /opt/IBM/WebSphere/AppServer/bin directory.

     cd /opt/IBM/WebSphere/AppServer/bin
     

     (Or, if the product is installed to a non-default directory, change directories to the WAS_HOME/bin directory.)
  4. Issue the command.

     ./ws_ant.sh -propertyfile /TMP/was_props/appserver.props \
                 -file /opt/IBM/WebSphere/AppServer/profileTemplates/default/actions/updatePorts.ant
     
     

  5. Open the admin console and view the changed port assignments.

     To view the port assignments...

     Servers > Application servers > server_name

     > [Communications] Ports.

  6. Run the script again and view the ports. Are they the same as before?

  The resulting dynamically assigned port values apply to all of the ports currently assigned to the AppSrv01 profile, for every server listed in serverindex.xml for the profile node name. Each port receives a new nonconflicting value. None of the old port value assignments are used because the port values are in use at the time of the new assignment.

• (Windows) Assign default ports to the AppSrv02 profile.

  The ANT script assigns nonconflicting ports by default. The defaultPorts=true special argument is needed. Identify the fully qualified directory paths, profile name, unique node name, and unique cell name. Then issue the command.

  1. Create the Java properties file encoded in ISO8859-1 file encoding, to assign default port values to the application server profile.

     For this example, assume that the system is a Windows operating system and that you create the following C:\temp\was_props\appserver.props properties file.

     WAS_HOME="C:/IBM/WebSphere/AppServer"
     was.install.root="C:/IBM/WebSphere/AppServer"
     profileName=AppSrv02
     profilePath="C:/IBM/WebSphere/AppServer/profiles/AppSrv02"
     templatePath="C:/IBM/WebSphere/AppServer/profileTemplates/default"
     nodeName=appserver_node02
     cellName=appserver_cell02
     hostName=myserver2.ibm.com
     defaultPorts=true
     
     

     Use double quotation marks around a Windows path name with spaces. Do not use quotation marks around the path name if there are no spaces in the path.

  2. Open a DOS command window.
  3. Change directories to the C:\IBM\WebSphere\AppServer\bin directory.

     cd "C:\IBM\WebSphere\AppServer\bin"
     

     (Or, if the product is installed to a non-default directory, change directories to the WAS_HOME/bin directory.)
  4. Issue the command.

     ws_ant.bat -propertyfile C:\temp\was_props\appserver.props
      -file "C:\IBM\WebSphere\AppServer\profileTemplates\default\actions\updatePorts.ant"
     
     

  5. Open the admin console and view the changed port assignments.

     To view the port assignments...

     Servers > Application servers > server_name

     > [Communications] Ports.

  6. Run the script again and view the ports. Are they the same as before?

  The resulting assigned port values are the same each time because the values are the default values. This method does not resolve conflicting port assignments.

  To view all port assignments for a profile, see the C:\IBM\WebSphere\AppServer\profiles\AppSrv02\config\cells\appserver_cell02\nodes\appserver_node02\serverindex.xml file. Issue the netstat -a command to see all ports in use on the machine.

• (AIX) Assign ports starting at 2050 to the AppSrv03 profile.

  The ANT script assigns nonconflicting ports by default. The startingPort=2050 special argument is needed. Identify the fully qualified directory paths, profile name, unique node name, and unique cell name. Then issue the command.

  1. Create the Java properties file encoded in ISO8859-1 file encoding, to assign default port values to the application server profile.

     For this example, assume that the system is an AIX operating system and that you create the following /usr/tmp/was_props/appserver.props properties file.

     WAS_HOME=/usr/IBM/WebSphere/AppServer
     was.install.root=/usr/IBM/WebSphere/AppServer
     profileName=AppSrv03
     profilePath=/usr/IBM/WebSphere/AppServer/profiles/AppSrv03"
     templatePath=/usr/IBM/WebSphere/AppServer/profileTemplates/default"
     nodeName=appserver_node03
     cellName=appserver_cell03
     hostName=myserver3.ibm.com
     startingPort=2050
     
     

  2. Open a command shell window.
  3. Change directories to the /usr/IBM/WebSphere/AppServer/bin directory.

     cd /usr/IBM/WebSphere/AppServer/bin
     

     (Or, if the product is installed to a non-default directory, change directories to the WAS_HOME/bin directory.)
  4. Issue the command.

     ./ws_ant.sh -propertyfile /usr/tmp/was_props/appserver.props \
                 -file /usr/IBM/WebSphere/AppServer/profileTemplates/default/actions/updatePorts.ant
     
     

  5. Open the admin console and view the changed port assignments.

     To view the port assignments...

     Servers > Application servers > server_name

     > [Communications] Ports.

  6. Run the script again and view the ports. Are they the same as before?

  After using the -startingPort option, the resulting dynamically assigned port values are not the same each time because the ANT script assigns nonconflicting port values starting from the startingPort number (port 2050 in this case). This method resolves conflicting port assignments.

• (Solaris) Use a port definition property file to assign ports to the AppSrv04 profile.

  The ANT script assigns nonconflicting ports by default. The portsFile=/opt/was/portdefs.our_appsrv_ex.props special argument is needed. Identify the fully qualified directory paths, profile name, unique node name, and unique cell name. Then issue the command.

  1. Create the Java properties file encoded in ISO8859-1 file encoding, to assign nonconflicting port values to the application server profile.

     Assume that you create the following /opt/was/portdefs.our_appsrv_ex.props properties file:

     WC_defaulthost=19080
     WC_adminhost=19060
     WC_defaulthost_secure=19443
     WC_adminhost_secure=19043
     BOOTSTRAP_ADDRESS=22809
     SOAP_CONNECTOR_ADDRESS=28880
     IPC_CONNECTOR_ADDRESS=9633
     SAS_SSL_SERVERAUTH_LISTENER_ADDRESS=29401
     CSIV2_SSL_SERVERAUTH_LISTENER_ADDRESS=29403
     CSIV2_SSL_MUTUALAUTH_LISTENER_ADDRESS=29402
     ORB_LISTENER_ADDRESS=39100
     DCS_UNICAST_ADDRESS=39353
     SIB_ENDPOINT_ADDRESS=37276
     SIB_ENDPOINT_SECURE_ADDRESS=37286
     SIB_MQ_ENDPOINT_ADDRESS=45558
     SIB_MQ_ENDPOINT_SECURE_ADDRESS=45578
     SIP_DEFAULTHOST=45060
     SIP_DEFAULTHOST_SECURE=45061
     

     The ports used in the port definition property file should reflect the template type. The ports in this example are for the default template type, and they might vary for other template types. The management template has three different portdef.props files, one for each servertype. They are adminagent.portdef.props, dmgr.portdef.props and jmgr.portdef.props. They can be modelled after the portdef.props file found in the template directory.

     Assume that you create the following /TMP/was_props/appserver.props properties file:

     WAS_HOME=/opt/IBM/WebSphere/AppServer
     was.install.root=/opt/IBM/WebSphere/AppServer
     profileName=AppSrv04
     profilePath=/opt/IBM/WebSphere/AppServer/profiles/AppSrv04
     templatePath=/opt/IBM/WebSphere/AppServer/profileTemplates/default
     nodeName=appserver_node04
     cellName=appserver_cell04
     hostName=myserver4.ibm.com
     portsFile=/opt/was/portdefs.our_appsrv_ex.props
     
     

  2. Open a command shell window.
  3. Change directories to the /opt/IBM/WebSphere/AppServer/bin directory.

     cd /opt/IBM/WebSphere/AppServer/bin
     

     (Or, if the product is installed to a non-default directory, change directories to the WAS_HOME/bin directory.)
  4. Issue the command.

     ./ws_ant.sh -propertyfile /TMP/was_props/appserver.props \
                 -file /opt/IBM/WebSphere/AppServer/profileTemplates/default/actions/updatePorts.ant
     
     

  5. Open the admin console and view the changed port assignments.

     To view the port assignments...

     Servers > Application servers > server_name

     > [Communications] Ports.

  6. Run the script again and view the ports. Are they the same as before?

  The resulting assigned port values are from a props file. Therefore, the values do not change. This method does not resolve conflicting port assignments.

Results

This procedure results in four different methods of port assignments with the updatePorts.ant script.
