The procedure described in this section is needed only for a server that has been upgraded to version 12.5 from an earlier server version. This procedure replaces the procedure in the Error Messages and Troubleshooting Guide for situations when the master database is corrupt, the master device is not affected, and one or both of the following conditions are true:
There is no current backup of the master database.
One or more user databases use space on the master device, and there are no current backups of those databases.
If you have current dumps of the master database and all databases that occupy space on the master device, you can use 12.5 dataserver to build a new master device. You can then load your dump of the master database and your database dumps.
Adaptive Server version 12.5 does not use the buildmaster binary to build the master device. Instead, Sybase has incorporated the buildmaster functionality in the dataserver binary.
The dataserver options you use to rebuild corrupt databases are:
-d master device path name
-b master device size
-w master | model
-z page size
-f[orcebuild]
See Chapter 1, “Building Servers Using dataserver” in the Utility Guide for more information, and the reference page for dataserver in the Utility Guide for information on how to use the options.
In Adaptive Server version 12.5, dataserver requires the following information to rebuild your databases:
master device size when it was first built
Logical page size of your current server’s installation
