Hi,
We have an Oracle 19c primary and standby database running on Exadata Cloud at the customer. Recently, we encountered high CPU utilization incidents on the standby database. Upon further investigation, I observed that the primary database was generating a significant amount of archive logs during specific hours. The substantial number of archive logs being applied to the standby database resulted in high CPU utilization. To address this issue, we should consider adding additional OCPUs to the standby database.
Please note that adding OCPUs will impact licensing, so ensure to verify before proceeding with any additional OCPUs.
