Installation guide

Examine the log file in $SYBASE/$SYBASE_ASE/init/logs.

After you resolve any problems, shut down Adaptive Server and use sqlupgrade to

complete the upgrade session.

When an Upgrade Fails

If the upgrade process fails, the installation program displays error messages.

Once you start Adaptive Server on the new version, you cannot start Adaptive Server on the

earlier version. Attempts to do so result in having to restore from backups.

If You Can Identify the Cause of the Upgrade Failure

If the error logs or messages clearly indicate the cause of failure, and you are confident that

your databases have not been damaged, you can attempt to fix the problem and immediately

re-run the upgrade.

If the upgrade process fails again and you cannot determine the cause of failure, check the

error log file to find out when and where the upgrade failed, and contact Sybase Technical

Support.

By default, the log file is located in $SYBASE/$SYBASE_ASE/install/

<servername>log.

Exit the sqlupgrade program.

Perform the necessary actions to fix the problem.

For example, if the error log indicates that the upgrade failed because your existing

databases do not contain enough space, use the alter database command to increase the

available space.

If needed, shut down Adaptive Server.

Shutting down the server enables the installation program to start the server and re-run the

upgrade session.

Start sqlupgrade again.

5. Select Upgrade Adaptive Server, and proceed with the upgrade.

Restoring Databases After a Failed Upgrade

You may need to restore your databases due to a failed upgrade.

• If you think the upgrade failure or its cause may have damaged your databases, restore the

databases from backups. For information on restoring databases, see the

System
