Step 1 - Patch Me If You Can. (Grid OOP Patching)

I’ve moved my blog from https://insanedba.blogspot.com to https://dincosman.com Please update your bookmarks and follow/subscribe at the new address for all the latest updates and content. More up-to-date content of this post may be available there.

I will patch all my database servers grid infrastructure from 19.16 to 19.20. As there are more than 20 servers to patch, we will use fleet patching. First i will patch a 2 node cluster grid infrastructure by using out of place ( OOP ) patching  methodology through gridSetup.sh in silent mode. Doc ID 2853839.1  and Patching Oracle Grid Infrastructure 19c using out-of-place SwitchGridHome video by Daniel Overby Hansen  can be used a reference. 
Later i will use patched grid homes to create a gold image for fleet patching of all grid homes.

Setup List:
 * Grid 19.3 Base Release (LINUX.X64_193000_grid_home.zip)
 * Grid 19.20 RU (p35319490_190000_Linux-x86-64.zip)
 * Grid 19.20 August MRP (p35656840_1920000DBRU_Linux-x86-64.zip)
 * Grid 555.1 Recommended One-off (p35372179_1920000DBRU_Linux-x86-64.zip)
 * Opatch Latest Version (p6880880_122010_Linux-x86-64.zip)

Grid Infrastructure Out of Place Patching

Preparation Phase:

Content of Response File:

Deploying new software to cluster nodes with a single command. (Grid RU + Grid MRP + Grid One-off)

Do not run root.sh script now. It will be executed after switching to new home completed. Otherwise as the destination grid home has not been configured as a 'CRS' home, it may corrupt the environment.
Once the switch grid home completed, content of inventory.xml under oraInventory is replaced. New Grid Home is tagged with CRS="true" flag.

Now new grid infrasture software ready to go. We will just execute root.sh scripts node by node. Wait for finish before executing on another node. Crs will be restarted from new grid home.

Final steps:
    * Listener.ora will be copied by gridSetup.sh. No action required.
    * Update all your shell scripts, .bashrc etc files to refer new grid home.
    * Do not forget to copy your custom glogin.sql etc files under old grid home to new grid home.

Hope it helps.

Ansible is a friend in need and a friend indeed for DBAs. I’ve moved my blog from https://insanedba.blogspot.com to https://dincosman.com Please update your bookmarks and follow/subscribe at the new address for all the latest updates and content. More up-to-date content of this post may be available there. In this blog post, I will mention about Redhat Ansible and show how you can patch your grid infrastructure by using it. Ansible is an open source, command-line IT automation software application written in Python. It can configure systems, deploy software, and orchestrate advanced workflows to support application deployment, system updates, and more. Ansible's main strengths are simplicity and ease of use. It is a little bit similar to dcli commands in Exadata environments, but much more powerful as you may run playbooks which consist of different tasks. Ansible stands out from other configuration management tools because it doesn't need agents installed on target host...

Ansible to Rule Them All I’ve moved my blog from https://insanedba.blogspot.com to https://dincosman.com Please update your bookmarks and follow/subscribe at the new address for all the latest updates and content. More up-to-date content of this post may be available there. In the previous post " Oracle Grid Software Patching by using Ansible Playbooks" , I mentioned how Ansible orchestration can be used to make Oracle Grid Software Patching a cleaner and simpler process. Now I will also patch database software using Ansible Playbooks. In this post,  I will use the blt01 host as the ansible host. The target environment is a two-node RAC database (gns01, gns02). I will patch the grid software to 19.22 using the out-of-place methodology with no downtime.  Although there are lots of useful blog posts about how you may use Ansible for automating tasks, there is not much about complete Oracle database software patching.  Ansible is simply installed by running "y...

Upgrade Your PostgreSQL Database: Major Steps and Minor Touches I’ve moved my blog from https://insanedba.blogspot.com to https://dincosman.com Please update your bookmarks and follow/subscribe at the new address for all the latest updates and content. More up-to-date content of this post may be available there. In this blog post, I will show how a complete PostgreSQL environment major update can be done. Minor upgrades are not a tough task; they are no different from a standard Linux package upgrade. As my production environment serves in an airgapped-environment, I will complete all the major upgrades with no internet connection. I've downloaded all the required whl and .rpm packages before the upgrade. Before starting, a short description of major and minor PostgreSQL upgrades is provided below: Major Upgrade: Upgrading PostgreSQL to a new major version, such as moving from 10 to 11 or 12 to 13. Major upgrades bring significa...
