CA Distributed Repository Access System (CA DRAS) Considerations

You can calculate the number of concurrent users that a CA DRAS server supports using the following formula:

For CA View

Solve for maxusers:

• Databases = number of the CA View databases
• Data sets = (number of the data file data sets for the CA View databases) + (number of the data file data sets for CA Deliver databases)
• maxusers = ((maximum available below-the-line storage – (databases * 1616) - (data sets * 528)) / 2424) and drop remainder

Based on the formula in the example:

Given several CA View databases up to 3428 users per DRAS server can be supported:

• 134 View data sets (extents)
• 0 Deliver data sets(extents)
• 8388608 bytes of maximum below-the-line storage
