MRP - Managed Recovery Process in Oracle Data Guard Oracle Data Guard — Managed Recovery Process (MRP) / Redo Apply The Managed Recovery Process (MRP) is a key component of an Oracle Data Guard physical standby database. It is responsible for applying redo generated by the primary database to the physical standby database so that the standby can remain synchronized with the primary. Oracle Data Guard is widely used to provide high availability, disaster recovery, data protection, and business continuity for Oracle Database environments. In a physical standby configuration, redo generated on the primary database is transported to the standby database. The standby then uses Redo Apply to apply that redo to its datafiles. The MRP is the process associated with this managed recovery operation. Oracle describes a physical standby database as a block-for-block copy of the primary that is maintained through Redo Apply, which continuously applies redo received from the prima...

How to Extend Swap Space on an LVM Disk in Linux Linux System Administration / LVM Guide This guide explains how to safely extend swap space when swap is configured on an LVM logical volume. It covers how to identify the current swap configuration, check available space in the Volume Group, and prepare the system before resizing the swap logical volume. Introduction Swap space is an area of disk storage that Linux can use when physical RAM becomes constrained. It provides additional virtual memory capacity, although it is significantly slower than RAM because it resides on storage. On Linux servers running Oracle Database, Oracle E-Business Suite, application servers, middleware, or other memory-intensive workloads, insufficient swap space can become an operational concern. If the server is using LVM and the swap area is configured on an LVM logical volume, the swap logical volume can be extended without repartitioning the entire disk. The general process is: ...
