Preparing to Install Maintenance Releases

Perform these tasks before you install a maintenance release.

1. From the command line, change to %IQDIR16%\bin64, and enter:

    start_iq -v2

   If SAP Sybase IQ returns a version string that does not match the baseline version in the cover letter, you cannot perform a rolling upgrade. See Database Upgrades for alternate upgrade instructions.

2. Download the maintentance release from the Software Downloads for EBFs and Maintenance site at: http://downloads.sybase.com/swd/base.do?client=support.
   For details about SAP Sybase software downloads, see Software Downloads Frequently Asked Questions at: http://downloads.sybase.com/swd/jsp/faq.jsp.
3. Back up your current installation and save copies of any changes you made to default login and post-login scripts. Before you proceed, make sure the backups are readable.
4. Check with your operating system vendor for information on the latest operating system patches. Use the recommended operating system patch. Do not use a patch that is earlier than the version suggested for your operating system.
5. In Interactive SQL, run sp_iqcheckoptions on each database and capture the output.
   sp_iqcheckoptions generates a list of current database values and options. Use these values to restore your database settings after you upgrade.
6. Validate your license against each database to ensure that your license maintenance support is in (or near) compliance. A server that has not had a maintenance contract for more than a year does not run. Validating your license(s) ensures that your database functions correctly after you install the ESD. See the SySAM documentation for validation procedures.
   Note: Uncompress the downloaded images and run the installer on the same machine where you install SAP Sybase IQ. Do not copy an uncompressed installation archive to a secondary machine and run the installer from that machine.
