Perform these tasks before you install a maintenance release.
In a terminal, 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.
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.
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.
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.
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.
