Information in this document applies to any platform.
SYMPTOMS:
This note is written for the 12.1.0 1.0 agent version, but applies similarly to other EM Cloud Control Agent versions.
Installing the Enterprise Manager (EM) 12c Cloud Control Agent fails at the configuration step while starting the Agent:

CAUSE: Below are some of the common reasons for Agent Startup failures Incorrect Hostname resolution Provided Agent port in use Insufficient ulimit settings Incorrect Timezone at Operating System
SOLUTION: 1. Correct the host entries in /etc/hosts file and also ensure that host name resolves to the right ip address. a.) Run the ifconfig command to get the IP address of the Agent host Unix: $ /sbin/ifconfig -a Windows: C:\> ipconfig /all b.) Update the /etc/hosts file to add an entry in the below format <IP address listed in above output> <hostname.domain> <short hostname> 2. Ensure that the Agent port provided during installation is not in use Unix: netstat -an | grep 3872 Windows: netstat -an | findstr 3872 3. Edit the agent_inst/sysman/config/emd.properties file Change: AgentListenOnAllNICs=TRUE To: AgentListenOnAllNICs=FALSE 4. Ensure that the openfiles and Max User processes shell limits are set to sufficiently higher values ulimit -n --- should be set to 8192 or higher ulimit -u --- should be set to 65535 or higher 5. Set Timezone correctly on the Agent machine export TZ=America/New_York --- This should be in region format; which should be listed in <AGENT_BASE_DIR>/core/<version>/sysman/admin/supportedtzs.lst 6. Start the Agent <agent_inst>/bin/emctl start agent 7. Add the Internal targets using: agent_inst/bin/emctl config agent addInternaltargets
