Installing version 15.0.2 over an existing 15.x Adaptive
Server
Determining Adaptive Server version
Verify that your current Adaptive Server installation is at version 15.x by
running the following query from
isql :
1> select @@version
2> go
If your server is not running, you can get a version string by running:
%SYBASE%\%SYBASE_ASE\bin\sqlsrvr.exe-v
If this shows that the Adaptive Server is not at version 15.x, you must upgrade
Adaptive Server. See Chapter 5, “Upgrading Adaptive Server.”
If your server is at a 15.x version level, you can begin installing Adaptive
Server 15.0.2.
Backing up Adaptive Server
Installing Adaptive Server version 15.0.2 overwrites the current Adaptive
Server software. Before installing, verify that your databases are error free and
that your $SYBASE directory is backed up.
To ensure that your database is error free, run dbcc checkdb , dbcc checkcatalog
and dbcc checkstorage prior to loading any new Adaptive Server binaries,
including the master database. If the dbcc commands reveal problems, check
the Error Messages and Troubleshooting Guide for actions necessary to fix the
problem. If the error is not listed in the manual, call Sybase Technical Support.
After you have verified that your database is error free, back up your $SYBASE
directory in case you need to roll back to the original version of the software.
