To execute an overlay installation you must first:
Verify that your current Adaptive Server is one of the releases prior to the version you are installing by running the following query from isql:
1> select @@version 2> go
If your server is not running, enter:
$SYBASE/$SYBASE_ASE/bin/dataserver -v
WARNING! Your software needs to be at a version lower than the version you are installing prior to applying this EBF.
Installing Adaptive Server version 15.0 Update #1 overwrites the current Adaptive Server. Prior to installing Adaptive Server version 15.0 Update #1, make sure that your databases are error free and back up your $SYBASE directory, in case you need to return to the original version of the software.
To ensure that your database is error free, run dbcc checkdb, dbcc checkcatalog and dbcc checkstorage prior to installing any new Adaptive Server binaries including the master database.
If any of the dbcc commands reveal problems, stop here and see the Troubleshooting and Error Messages Guide for more information.
