Starting and Stopping Connection Manager

Connection Manager Control

You can start the Oracle Connection Manager from any node where Oracle Net is installed. To see an example of how the CMCTL issues a START command, view the code below.
dilbert> cmctl start

CMAN processes

CMAN processes runs on your server with the Unix ps command. To see an example of this process, view the code below.

dilbert> ps -ef | grep cm | more
  oracle 44456     1   0 15:29:12  pts/3  0:00 /u01/oracle/product/8.0.5/bin/cmadmin 
  oracle 44730 40790   4 15:33:21  pts/3  0:00 grep cm 
  oracle 46508     1   0 15:29:14  pts/3  0:00 /u01/oracle/product/8.0.5/bin/cmgw 

CMAN Processes Review

To review, the CMAN processes are:
  1. Connection Manager Gateway Process (CMGW), a gateway process acting as a hub for the Connection Manager
  2. Connection Manager Administrator (CMADM), a multi-threaded process that is responsible for all administrative issues of the Connection Manager. Its primary function is to maintain address information in the Oracle Names Server for the legacy SQL*Net 2.x and NET 8.x clients
To stop the Oracle Connection Manager, initiate a connection from a client to any active database for which a source route address has been created and issue the cmctl stop command.

View the code below to see an example
dilbert> cmctl stop
