Error description

• Synergy CLI sessions started in forked process are sensitive to
  SIGINT (CTRL+C)
  
  Start a webmode CLI session using the command:
  export CCM_ADDR=`ccm start -d <database path> -s
  http://server:port -pw password -m -q`
  
  Running "ccm set role" command will display the current role.
  
  Now, type the same command and press "Ctrl + C" combination of
  keys.
  Further, executing any java CLI commoand displays the following
  message:
  
  Warning: Cannot connect to address <server>:<port>:<IP Address>
  
  Expected Result:
  
  The session should not be killed on pressing "Ctrl + C" key.
  
  Sessions started without scripting or backquotes behave normally
  (ie. are not sensitive to SIGINT)
  

Local fix

• Avoid using scripted session startups
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Synergy CLI users using web mode in UNIX platforms.          *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * Rational Synergy CLI session can be started by executing     *
  * "ccm start" command. Multiple Synergy CLI sessions can be    *
  * started by using "-m" option in the "ccm start" command.     *
  * Once the session is started, the session address needs to be *
  * set to the "CCM_ADDR" environment variable, so that any      *
  * Synergy commands executed in that console shall run using    *
  * that session address.                                        *
  *                                                              *
  * In UNIX platforms, the session start command and setting the *
  * CCM_ADDR environment variable can be performed by a single   *
  * command.                                                     *
  *                                                              *
  * For example:                                                 *
  * > export CCM_ADDR=`ccm start -d /data/ccmdb/basedb -s        *
  * http://synergyserver.com:8400 -nogui -m -q -pw xxx`          *
  *                                                              *
  * If the Synergy CLI session start command and CCM_ADDR        *
  * setting is performed through a single command, then pressing *
  * CTRL+C when there are no active commands running, would kill *
  * the Synergy CLI session.                                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * It is recommended to split the commands, such that first     *
  * start the Synergy CLI session and then set the running,      *
  * shall not kill the Synergy CLI session.                      *
  *                                                              *
  * For example:                                                 *
  * > ccm start -d /data/ccmdb/basedb -s                         *
  * http://synergyserver.com:8400 -nogui -m -q -pw xxx           *
  * synergyserver.com:12345:150.100.20.10                        *
  *                                                              *
  * > export CCM_ADDR=synergyserver.com:12345:150.100.20.10      *
