Oracle Database RMAN Backup Script

RMAN Backup Script
Oracle Recovery Manager (RMAN) is a comprehensive tool designed to efficiently back up and recover Oracle databases. It works closely with the server, providing block-level corruption detection during backup and restore. RMAN backups are created using the 'BACKUP' command. The primary purpose of RMAN backups is to protect your data. In the event of a media failure or disaster, you can restore your backups and recover lost changes.

For more detailed information about RMAN backup concepts, you can refer to the Oracle Help Center. Additionally, if you are interested in creating an Oracle database backup using RMAN, you can find step-by-step instructions on how to do so in the Oracle-Patches website.

Upgrading Issue for RHEL 7 to 8 With Leapp

Overview The Leapp utility is a framework for updating and upgrading operating systems as well as applications. The operations of this utility consist of two phases 1. the preupgrade Phase – that chack the upgrade possibilities and 2. the actual upgrade phase – that map packages between previous and current versions of the software packages. Issue – 01: After running ‘ sudo leapp preupgrade ‘ sometimes you find the below issue in ‘ /var/log/leapp/leapp-report.txt ‘. Detail: Risk Factor: high (inhibitor) Title: Leapp detected loaded kernel drivers which have been removed in RHEL 8. Upgrade cannot proceed.

Upgrading Oracle Linux 6 to 7

Overview It is possible to upgrade an Oracle Linux 6 system to Oracle Linux 7.6 under the following conditions: The system meets the minimum installation requirements for Oracle Linux 7 as described in Chapter 1, System Requirements and Limits. The Oracle Linux 6 system has been completely updated from the ol6_x86_64_latest channel or ol6_latest repository. UEK R3 or UEK R4 has been installed on the system to be upgraded and is the default boot kernel. Upgrading from UEK R2 is not supported. Note that the system is upgraded to use the UEK R5 release provided with Oracle Linux 7.6. Upgrading is supported only for systems that are installed with the Minimal Install base environment. If additional packages are installed from an alternative repository or channel, upgrade might fail or the resulting upgrade might not function as expected. reference: https://docs.oracle.com/en/operating-systems/oracle-linux/7/relnotes7.6/ol7-install.html#ol7-upgrade-ol6 Verifying the system before Upgrade: #
