Oracle E-Business Suite Java Critical Patch Update Checker (EJCPUC) has been updated with the May 2026 Critical Security Patch Update (CSPU). We strongly recommend that you run EJCPUC against your EBS environment to:
- Identify the current Java CSPU/CPU level for the various Java Homes in your EBS environment.
- Identify required Java CSPU/CPU patches and security fixes for your environment.
Obtaining EJCPUC
EJCPUC is available with Patch 37171025. Instructions for running EJCPUC are documented in the README.txt file included with the patch.
Patch 37171025 provides a script, ejcpuc.sh which you will run on the application tier and database tier. Running EJCPUC will generate a report which includes your current Java CSPU/CPU level and recommended updates.
Usage Tips
- Read the README carefully. The README for this patch includes a number of usage scenarios and examples.
- Always use the latest version of EJCPUC. New Java CSPU/CPU patches and fixes will not be checked by older versions of the utility.
As part of your monthly security patching activity:
- Run EJCPUC on the application tier and database tier before applying CSPU/CPU patches and fixes. You should run EJCPUC before applying the latest CSPU/CPU patches to identify your Java versions and recommended updates.
- Apply all recommended patches as soon as possible. If EJCPUC reports recommended updates, you should apply these to your environment .as soon as possible.

Run EJCPUC to review and report on your Java CSPU/CPU level. You may be required to review and report on the Java CSPU/CPU level of your EBS environment. To check the Java CSPU/CPU level in your environment, run EJCPUC and review the report to determine your Java CSPU/CPU level.
