Patching Oracle databases is a critical maintenance task that ensures system security, stability, and performance. However, patching a standby database in a Data Guard configuration requires careful execution to maintain data protection and high availability. This blog post explores an Ansible playbook we've developed to automate the Oracle standby database patching process, making it more reliable, consistent, and efficient. yaml # File: standby_db_patching.yml --- - name : Apply Oracle Patch on Standby Database hosts : "{{ hostlist }}" become : yes vars : oracle_home : /opt/oracle/product/19.3.0/db_1 local_patch_dir : /tmp patch_dir : /oraback/patch patch_db_zip : p37642901_190000_Linux - x86 - 64.zip patch_opatch_zip : p6880880_190000_Linux - x86 - 64.zip tasks : # Tasks will be discussed in detail below Why Automate Oracle Patching? Manual patching processes are prone to human error, time-consuming, and often lack proper...

🔄 Automating Oracle GoldenGate Patching with Ansible Maintaining up-to-date Oracle GoldenGate environments is crucial for ensuring optimal performance and stability.

Understanding Oracle Local Registry (OLR) in Oracle RAC – A Deep Dive Oracle RAC (Real Application Clusters) uses several key files to coordinate and maintain cluster operations. Among these, the Oracle Local Registry (OLR) plays a crucial role during the early stages of node startup. In this blog, we will explore: 📁 What OLR is and where it resides ⚙️ Its role in the Oracle RAC architecture 🔄 Differences between OLR and OCR 🛠️ Managing and backing up the OLR ✅ Best practices for working with OLR 📘 What is OLR? The Oracle Local Registry (OLR) is a local, node-specific configuration file used by Oracle Grid Infrastructure. It stores data necessary for starting and maintaining Clusterware stack components on a node, especially before shared storage is accessible. Key information stored in the OLR includes: ASM startup configuration Local resource dependencies Node-level cluster configuration Location (Linux/Unix): /u01/app/11.2.0/grid/cdat...
