How to regenerate a search index in Rational Change

Technote (troubleshooting)


Problem(Abstract)

How do you regenerate a search index in IBM Rational Change when a search results in only some Change Requests being found?

Symptom

When you search for a Change Request (CR) and the results returned do not include some CRs you know should be there, you may have to regenerate or rebuild the search index.


Cause

Unknown.

Diagnosing the problem

Troubleshooting tips:

  • Ensure that Access Control Lists (ACL) do not prevent access to these CRs.
  • Ensure that the attribute searched is searchable.

    Check under Search > Results Format which attributes are listed under Chosen Attributes.

Resolving the problem

Procedure:

The following steps will help resolve the issue.

Caution! This action creates an index across all databases for the installation. This can take time to process, and search results may be incomplete while the index is rebuilding. Contact Rational Client support if you want to verify the index before you attempt a rebuild.

  1. For Rational Change 5.2, remove the files below from wsconfig/system and index directories:

    rm create.tmr enabled.tmr searchInformation.dat search.lock

    rm -Rf index


    Any .redo or .idx files in the system directory exist due to a failed recreate and would not exist if an index generation had succeeded.

    For Rational Change 5.3 and 5.3.1, remove the same files from the wsconfig/search and index directories.

  2. Log into Rational Change as the admin user


  3. Navigate to the Administration > Search > Status tab


  4. Click on Regenerate Index

    If the Regenerate Index and Update Index buttons are missing, then rename or delete following file in Rational Change 5.2:

    <CHANGE_HOME>/jetty/webapps/change/WEB-INF/wsconfig/system/search.lock

    In Rational Change 5.3 and 5.3.1 rename or delete following file instead:

    <CHANGE_HOME>/jetty/webapps/change/WEB-INF/wsconfig/search/search.lock

NOTE: It is possible to create the index from the command line using a Perl Script. For example: Consider the following debug script to create the search index: create_change_index.pl

     my $database= $aUser->getUserDatabase() ;
     print "db: ".$database."!";
     my $tmpstr = $csapi->
    CreateIndex($aUser);
