Use isql to run the new installmaster script included with this release.
Enter:
isql -Usa -P<sa password> -S<servername> -n -i$SYBASE/$SYBASE_ASE/scripts/installmaster -o<output file>
Save the output to an operating system file.
If you have modified any of the Sybase system stored procedures without changing the names, executing installmaster overwrites your modifications. Reload the modified stored procedures after you run the installmaster script.
