If you do not have a sybsystemdb, and will not be using two-phase commit or DTM applications, create a sybsystemdb with a minimum of 4MB.
If you will be using two-phase commit or DTM, you can either:
Create a minimum-sized sybsystemdb for upgrade and expand it later, or
Create a sybsystemdb of 5 to 20MB, depending on your expected usage. Approximately 25 percent of the database should be data storage, and 75 percent should be log storage.
