Installing Adaptive Server version 15.7 overwrites the current
Adaptive Server software. Before installing, verify that your databases
are error free, and back up the Sybase directory.
- To ensure that your database is error free, run dbcc
checkdb, dbcc checkcatalog and dbcc
checkstorage before 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.
- Adaptive Server provides the uninstmsgs.ebf script for backing up sysmessages before upgrading
to 15.5. Use it to back up sysmessages before running instmsgs.ebf.
