Install WebSphere Application Server Liberty

The requirements and procedure for Installing WebSphere Application Server Liberty (WLP).


Before you begin

Ensure that we have access to a version of WLP for z/OS® that includes z/OS Connect, for example 16.0.0.2.


This procedure installs WLP and sets up a server.


Procedure

  1. Install WLP by following the procedure detailed in Install Liberty using Installation Manager. Note that for the remainder of these instructions, this directory structure is referred to as WLP_ROOT.
  2. Create a new server by following the procedure detailed in Creating a Liberty server manually Refer to Set up z/OS Connect which describes how to enable z/OS Connect on the created server. Attention: You do not need to perform the optional WebSphere optimized local adapters (WOLA) steps.
  3. Enable the TXRRS authorized service by following the procedure detailed in Enabling z/OS authorized services on Liberty for z/OS
  4. Validate that the TXRRS authorized service has been set up correctly by:
    1. Starting the server. Follow the procedure detailed in Starting and stopping a server from the command line
    2. View the server logs which are at: 
      WLP_ROOT/usr/servers/server_name/logs/message.log
      These are ASCII files, and should contain output similar to the following:
      A CWWKE0001I: The server server1 has been launched.
I CWWKB0103I: Authorized service group LOCALCOM is available.
I CWWKB0103I: Authorized service group PRODMGR is available.
I CWWKB0103I: Authorized service group SAFCRED is available.
I CWWKB0103I: Authorized service group TXRRS is available.
I CWWKB0103I: Authorized service group WOLA is available.
I CWWKB0103I: Authorized service group ZOSDUMP is available.
I CWWKB0103I: Authorized service group ZOSWLM is available.
I CWWKB0103I: Authorized service group CLIENT.WOLA is available.
I CWWKB0108I: IBM CORP product WAS FOR Z/OS version 16.0 successfully registered with z/OS.

      Check the output to see if the TXRRS authorized service group is available. In the preceding example, the line in bold text shows that the service group is available.

      The MQ Service Provider needs this service group to be available.

    3. Stopping the server. Follow the procedure detailed in Starting and stopping a server from the command line
