It is said that when install, select customer install and select SCE in install guide of OCMS, but actually when in install l progress, only allow to select component ,such as presence, proxy registrar. No entry for selecting SCE.
How to install SCE and test example projects in SCE?
Firstly the SUBJECT of your question reads SEC in place of SCE and it is a CUSTOM install not a CUSTOMER Install.
Coming to answer your question, if you find the latest install guide, you wont see the SCE pre and post install etc in it. SCE has been taken off OCMS. OCCAS (Oracle Communications Converged Application Server) will be the Execution platform of SIP from now on. OCMS Applications too would be merged into OCCAS.
