Script for applying EBS technology patches

A key step in applying EBS CPU patches is to decide which technology patches are required by both ETCC checker and quarterly CPU Release document for WebLogic and Oracle Homes of Fusion Middleware. After the list of required patches for each component is decided, I write a shell script to run the patching process and make it more consistent and much quicker cross nodes and different instances (Dev, QA, Prod).

Pre-steps: place technology patch files to a location shared by many servers. For January 2025 CPU patches (Doc ID 3061170.1), 3 patches are needed and copied to each sub-folder WLS and FMW_Comm under location /path/to/Jan2025_CPU:

 

- FMW_Comm

Holds 3 Fusion Middleware patch files and opatch response file ocm.rsp. Each .zip file is unzipped to its own sub-folder here.

$ cd /path/to/Jan2025_CPU/FMW_Comm

$ ls *.*

ocm.rsp

p33974106_111190_Generic.zip

p33960746_111190_Generic.zip

p34714760_111190_Generic.zip

Do unzip and chmod just one time.

$ unzip p33974106_111190_Generic.zip

$ unzip p33960746_111190_Generic.zip

$ unzip p34714760_111190_Generic.zip

Open READ permission for other OS accounts to run the script to patch instances on other servers: (Or, remove the sub-folder and then unzip the .zip file again before each opatch run.)

$ chmod -R +r 33974106

$ chmod -R +r 33960746

$ chmod -R +r 34714760

$ ls -l | egrep "^drw" |awk '{print $9}'

33974106

33960746

34714760

- WLS 

Holds 3 WLS patch zip files, and each file is saved in its own sub-folder:

13845626/p13845626_10360231017_Generic.zip

35476084/p35476084_1036_Linux-x86-64.zip
