All logs are the same size on the production server and the recovery server. The log size affects the amount of data that Assure MIMIX for AIX processes for each transaction.
By increasing the size of the logs, processing is reduced and the elimination of common blocks in the undo logs is more efficient. Decreasing log size results in a more up-to-date replica on the recovery server, because log transfers occur more frequently.
The journal should contain at least eight logs
Minimum log size is 2MB
Maximum log size is one-half of the available RAM but not greater than 512 MB
To calculate log size, you need an estimate of average write throughput, and the required processing rate. For the required processing rate, if Assure MIMIX for AIX processes one log every 60 seconds, the replica will be one minute behind the production system.
