Calculating RBB Storage

Site administrators can direct the CA ADS runtime system to calculate the amount of storage required for record buffer blocks (RBBs) instead of using the size specified in the system generation ADSO statement. Calculated storage reduces the amount of wasted space in the storage pool but slightly increases CPU usage. This option is a good choice for storage-constrained systems.

Calculation of runtime RBB storage is enabled in the system generation ADSO statement.
