Remediation/Fixes

Check the accSuiteRelease.properties file located in <DB2_install_dir>/db2tss. If the accSuiteRelease.properties file does not exist, or if the properties file exists, but the version number in the properties file is less than V2.0.0, reinstallation of the latest release is necessary:

1. Download the Accessories Suite and extract the installer.
2. Stop the text search service: db2ts stop for text
3. Run the installer to upgrade your existing setup
