Solution Unverified - Updated -

Environment

  • RedHat JBoss Enterprise Application Platform (EAP)
    • 5 EL5
    • 5 EL4

Issue

  • What is the difference between EL5 vs EL4 ? I am in RHEL 4. but when i check the kernel package, it is showing el5. Can we use the el5 package in RHEL 4?

Resolution

  • The EL5 & EL4 is nothing but the Enterprise Linux version 5 & 4 And both version's are listed in security updates means these are affected product versions. Eg. See link [1] in which EL4,EL5,EL6 are listed which is affected product versions.

  • Find the difference between these 2 product by referring to product documentation of both product[2].

We can use the el5 packages with RHEL 4 also but not all the packages. Only some packages like kernel.
