a. Memory – Ensure that there is enough memory. This will determined by the number of GoldenGate processes which will be configured on the server.
b. Memory Per Process – Dependent on the size of the transactions and the amount of concurrent transactions in the database. By default one Goldengate extract or replicat process can take up to 8G of memory.
c. Swap space – Configure reasonable swap space in case Goldengate processes swap due to low memory condition.
d. Disk space – Enough disk space to hold the trail files for the required retention period. As a starting point it could be made approximately the same as the amount of archive logs generated in a specific time period. Also consider the amount of space that might be needed for an initial load.
