Configuring the directory for temporary search and query results

You must configure the directory for IBM® InfoSphere® Information Governance Catalog to work with large search and query results.

Before you begin

You must have the Administrator role in IBM WebSphere® Application Server Liberty Profile or in IBM WebSphere Application Server Network Deployment if you must define the Java™ system property vr.temp.location.

About this task

Searches and queries in InfoSphere Information Governance Catalog might generate a large number of results. If the directory where the search or query writes its results is not large enough, performance of WebSphere Application Server Liberty Profile or WebSphere Application Server Network Deployment degrades.

If the owner of the WebSphere Application Server Liberty Profile or WebSphere Application Server Network Deployment process has write access to java.io.tmpdir, results are written to that directory. Otherwise, results are written to the directory assigned by the Java system property vr.temp.location, if defined. If vr.temp.location is not defined, results are written to java.io.tempdir.

The results directory must be checked in the following situations:
  • After any change in the setup of WebSphere Application Server Liberty Profile or WebSphere Application Server Network Deployment
  • After any change to a WebSphere Application Server user

Procedure

  1. If the owner of the WebSphere Application Server Liberty Profile or WebSphere Application Server Network Deployment process cannot be given access to java.io.tmpdir, assign a different directory by doing these steps:
    1. In the left pane of IBM WebSphere Administrative Console, click Servers > Application servers.
    2. Select your server and then click Process Definitions > Java Virtual Machine > Custom Properties.
    3. Click New to create a Java system property.
      • In the Name field, type vr.temp.location.
      • In the Value field, type the full path of the directory for search and query results.
  2. Check the amount of free space in the results directory. Make available at least 1 GB of free space for every five concurrent users.
  3. Restart WebSphere Application Server Liberty Profile or WebSphere Application Server Network Deployment.
