Troubleshoot the Server

Determine the cause of problems and apply the recommended solution.

To determine the cause of an error, first look in the log file of the utility being used, to identify the task the utility was performing when it failed. Then check the server error log.

This table lists possible causes and solutions for common problems that you might encounter during a first-time installation or upgrade. If you continue to have problems, retry the installation or upgrade.

If the installation program or srvbuild unexpectedly quits, or if you cannot correct the problem, see the Error Messages and Troubleshooting Guide.

Problem	Solution
The installation program cannot start Adaptive Server.	Make sure you meet RAM requirements. If you have the required RAM, remove, then reinstall all applications to the hard drive and restart the installation. After Adaptive Server is installed, there should be 25MB of free disk space left in the disk drive. Verify that you are logged in as system administrator. You must log in as an administrator to start Adaptive Server. Adaptive Server may not start if it cannot find a SySAM license and if the grace period has expired. Check the Adaptive Server error log for the cause of the license checkout failure and fix the issues.
Sybase products cannot locate their required DLLs.	The installation program makes several modifications to your operating environment to locate required files. Log out of Windows, and log in again for the changes to take effect. Use the system sdministrator login account or assign yourself system sdministrator privileges. Verify that you are logged in to Windows as a member of the Administrators group.
After upgrading Adaptive Server, Server Config does not run.	Exit and restart Server Config.
The installation program cannot connect to the upgraded Adaptive Server.	Exit and restart Server Config.
Cannot start Adaptive Server as a service on a Windows 32-bit machine.	You cannot start Adaptive Server as a service on 32-bit Windows OS machines because it cannot open the `master` device. This occurs because the installation process configures the Adaptive Server service to run as "LocalSystem" instead of "Administrator." You can successfully access Adaptive Server by logging in as Administrator and running the start_server.bat file, but attempting to start Adaptive Server as a service fails due to incorrect permission settings. To resolve this issue: Go to Control Panel > Administrative Tools > Services > Sybase_SQLServer_`servername`. Right-click Sybase_SQLServer_`servername` and click Properties. Click the LogOn tab, and choose This account. Provide your login and password, and click OK. You can now start Adaptive Server as a service.
