Create an in-memory temporary database using the Sybase Control Center Administration Console. 
Prerequisites
Consider these database attributes:
- Size :
-  sp_estspace helps you estimate table and index space requirements based on the definition of a specific table. See the Adaptive Server Reference Manual .
 
- Space for planned views, stored procedures, defaults, rules, and triggers
 
- Size of the transaction log
 
- Space for anticipated expansion
 
 
- Database device location, and whether there is enough space on that device.
 
- Transaction log location – Sybase recommends that you store the transaction log on a different device than the data.
