RHSM product certificate gets deleted on yum update

Issue

• we have several RHEL 6.6 installations and use Red Hat Subscription Management.

• On many systems we also have installed JBoss EAP 6.x via the RPM repository.

• So under /etc/pki/product we have the following two certificates:

[root@localhost ~]# ls -l /etc/pki/product
-rw-r--r--. 1 root root 2167 Oct 16 12:43 183.pem
-rw-r--r--. 1 root root 2159 Oct 16 11:21 69.pem

[root@localhost ~]# subscription-manager list
+-------------------------------------------+
    Installed Product Status
+-------------------------------------------+
Product Name:   JBoss Enterprise Application Platform
Product ID:     183
Version:        6.0
Arch:           x86_64
Status:         Subscribed
Status Details:
Starts:         ...
Ends:           ...

Product Name:   Red Hat Enterprise Linux Server
Product ID:     69
Version:        6.6
Arch:           x86_64
Status:         Subscribed
Status Details:

Ends:           ...

• In order to install OS patches monthly we have the need to just install updates from rhel-6-server-rpms and not the ones from jb-eap-6-for-rhel-6-server-rpms.

• Therefore we use:

[root@localhost ~]# yum update --disablerepo=jb-eap-6-for-rhel-6-server-rpms
Loaded plugins: product-id, protectbase, subscription-manager

However after installing updates with this command, the product certificate from JBoss EAP gets deleted:

[root@localhost ~]# ll /etc/pki/product
-rw-r--r--. 1 root root 2159 Oct 16 11:21 69.pem

[root@localhost ~]# subscription-manager list
+-------------------------------------------+
    Installed Product Status
+-------------------------------------------+
Product Name:   Red Hat Enterprise Linux Server
Product ID:     69
Version:        6.6
Arch:           x86_64
Status:         Subscribed
Status Details:
Starts:         ...
Ends:           ...

• But this is not desired, since the subscription needs to stay attached! And the JBoss EAP is obviously still installed!
• Do you have a solution to this problem? We think it might be cause by the product-id yum plugin?
