When uninstalling products from the same server, the product that was installed first must be uninstalled last. During the installation of the first product, the Service Database is created and the other products subsequently access it. Uninstalling the product installed first will also uninstall the Service Database that will disable the sm_service command for those products, prevent their proper operation and uninstallation.
You can determine what product software was installed first by performing this check:
-
Use a text editor to open the ic-serviced script.
-
For CentOS, ic-serviced is located in the /etc/init.d directory
-
For Linux, ic-serviced is located in the /etc/init.d directory
-
-
-
Find the value of the SMHOME variable.
The value of SMHOME indicates which product was installed first.
