I am trying to install 12c Enterprise Manager and unable to solve recommendation" Oracle recommends either setting memory_target or SGA_TARGET(ASSM) to manage EM repository instance Memory." My PARAMETER VALUES FOR PGA_AGGREGATE_TARGET=1G, SGA_TARGET=2G,SGA_MAX_TARGET=2G, MEMORY_TARGET=3G. I will appreciate your help to solve this prerequiste since it's not letting me move forward :(
You are required to set the Database Initialization Parameters in the existing databases that will house the EM repository. You have 2 options:
1) If you are not aware of how to set these parameters in DB then use the EM DB template that we have with all these parameters defined for doing the EM install
Read about these DB templates from here : http://docs.oracle.com/cd/E24628_01/install.121/e22624/appdx_seed_db_template.htm#CACIJIDC
These templates are avaliable on OTN http://www.oracle.com/technetwork/oem/enterprise-manager/downloads/db-templates-1841012.html
2) Refer the DB guide on how to set these parameters or get in touch with your DBA team.
The asker has clearly illustrated that he has set those init parameters, but you again ask him to lookup how to setup those parameters, I wonder why you even bother to respond. By the way I am now facing the same problem, and your response doesn't help.
