Installing and setting up the application server

You must prepare an application server before you begin the installation of the InfoSphere® MDM application.

InfoSphere MDM components run inside WebSphere® Application Server. The application server provides infrastructure for component-to-component communication, authentication, and logging.

You can choose to prepare a new application server or reuse an existing application server.

Review these prerequisites before you prepare the application server for InfoSphere MDM installation.

  • Ensure that you installed any prerequisite software and that the correct environment is set up.
  • Set the database utility for DB2® or Oracle to your system path. Microsoft SQL Server does not require this step.
  • Review the application server configuration worksheet to understand the basic parameters that are requested during the installation process. Completing the worksheet ensures that you have the basic information necessary to complete the installation. For multiple instances, copy the worksheet and prepare a separate worksheet for each deployment.
  • Use the wasadmin ID when you prepare the application server. If you are using Db2, this ID must own a Db2 client or a Db2 instance. The ID must be a member of the WebSphere MQ mqm group if you are using WebSphere MQ for messaging. This group is used to administer WebSphere MQ.
  • Ensure that you set up the WAS_HOME and the JAVA_HOME Java™ path for IBM® WebSphere Application Server.
  • Ensure that there is no server named server or cluster named cluster.
Important: You must have the WebSphere Application Server deployment manager (Dmgr) JVM Heap size arguments set to 2048 MB and 4096 MB, as described in this IBM Support article. To increase the heap size:
  1. Open the WebSphere Application Server Integrated Solutions Console and go to System Administration > Deployment Manager.
  2. Under Server Infrastructure, expand Java and Process Management, then click Process definition.
  3. Under Additional Properties, click Java Virtual Machine.
  4. Set the Initial heap size to 2048 MB and the Maximum heap size to 4096 MB.
  5. Click OK, save your changes, and synchronize your changes with the nodes.
