Hi Guys,
I m getting below, while starting replicat on target.

Hi,
Error:
GGSCI (ggtarget) 16> start replicat RLOAD
Sending START request to MANAGER ...
ERROR: opening port for MGR MGR (Connection refused).
You can start Manager, but when you try to start Replicat, GGSCI gives me a connection timeout error
Solution:
GoldenGate uses a TCP/IP socket to communicate between local processes. When you issue a START, STOP, SEND, or other command in GGSCI, the command interface will try to open a local port for the process.
Here is how to find out which local ports these processes are listening on. In the dirpcs directory, there will be one file for each running GoldenGate process.
For Manager, the file name will be MGR.pcm.
For Extract, it will be <GROUP_NAME>.pce.
For Replicat, it will be <GROUP_NAME>.pcr.
These are text files that can be viewed by using cat or any equivalent command. For example, the MGR.cpm file content will read like this:
PROGRAM MGR PROCESSID MGR PORT sys1.4356 PID 60070
After the keyword PORT will be the local hostname and the port number that Manager is supposed to be running on. In the preceding example, the hostname is sys1, and the port is 4356.
The program (ggsci) tries to use that hostname to communicate to the process (Extract/Replicat/Manager) when the command is issued in GGSCI. If you get a timeout or connection-refused error on the command, that means GoldenGate could not connect to the local host. Most of the time, you should have no problem connecting to a local host, but when you have the wrong IP address or routine table configured in your TCP/IP settings, connection errors can happen.
To troubleshoot this, follow the steps below
1. Try to ping that host name from the OS shell to see if it goes to the correct IP address (which should be the one for the local system).
2. If the ping is successful, try to telnet to the Manager port on your local host. You will be able to see your telnet session connect if a Manager is listening on that port.
Here is an example:
shell>telnet
telnet> open sys1 4356
Trying 100.100.100.100...
Connected to sys1.oracle.com (100.100.100.100).
Escape character is '^]'.
3. If your telnet session times out or gets a connection-refused error, that means either the hostname is wrong or the port number is wrong.
If the ping to the hostname listed in the pcm/pce/pcr file fails, or if you cannot connect your telnet session to the port listed in the file(s), contact your network engineers to get the TCP/IP issue resolved.
Hope this information helps.
Thanks & Regards
