COSFSMAC Rule

When Control-O/COSMOS determines that an object is not in its desired status, it searches for a method to set the object to its desired status. When an appropriate method is found, the following internal message is issued:

where

• dbname – Name of the Working Object database containing the object to be modified.
• row – Number of the database row describing the object to be modified.
• rulename – Name of the Method rule to be used to modify the object.
• parms – Parameters (if any) to be passed to the Method rule.

This message triggers rule COSFSMAC that:

• Specifies the Object database containing the object to be modified as the current Global Variable pool (Reserved User-defined variable %%$GLOBAL).
• Specifies the row describing the object to be modified as the current database row (Reserved User-defined variable %%$DBROW).
• Triggers the specified Method rule.

Since the COSFSMAC rule performs the above routine tasks, it simplifies coding of Method rules. Method rules assume that when they are triggered, the Global variable pool and database row are already set. Only actions to be performed (for example, issuing a START command) need to be included in the Method rule.
