To verify that your system environment is configured correctly:
Determine whether your server supports an upgrade to Adaptive Server 15.0.3.
Verify that the computer on which you plan to upgrade the Sybase products meets the system requirements specified in “System requirements”.
Set the environment variables by sourcing the SYBASE.[csh, sh, env]. file. Running this script multiple times can cause problems. Only run it once.
Verify that you installed Adaptive Server 15.0.3 in a different directory than your earlier Adaptive Server installation.
If you overwrote your earlier server installation:
Restore it from your most recent backup.
Reinstall the product files for Adaptive Server in a different directory.
Continue with the upgrade.
