    A Critical Patch Update is a collection of patches for multiple security vulnerabilities. These patches address vulnerabilities in Oracle code and in third party components included in Oracle products. These patches are usually cumulative, but each advisory describes only the security patches added since the previous Critical Patch Update Advisory. Thus, prior Critical Patch Update advisories should be reviewed for information regarding earlier published security patches. Refer to “Critical Patch Updates, Security Alerts and Bulletins” for information about Oracle Security advisories.

    Hi @User_D334D ,

    Welcome to the Oracle Analytics community and forum.

    1. If you look at the page covering the October 2025 Critical Patch Update you see the list of products. It will depends on your environment and what products you have or not.
    2. Each patch comes with its own "read me" that explain the installation process and if it can be done online or require a downtime
    3. You usually patch everything. The order in which you apply patches in your environments depends on your own company processes.
    4. Depends on your own company processes.
    5. Nothing is mandatory, as long as you accept the risks of not applying them. It's usually security patches, if you are happy to stay with a potentially vulnerable environment, then do not apply the patches. This again is something that is decided or driven by your own company processes.

    Did you just install OBIA a few months ago? If not, you already went through previous critical patches. Look at what your company did with those and validate internally that it's fine to do the same. Or ask your architect or security people directions on what the internal processes for patching are.
