Error description
For users attempting to connect to a remote z/OS system, they may experience issues with the connection terminating after the initial connection. The following messages will be issued from the client side: RSEG1057: The remote system connection has been lost CRRZI9003E: Unable to connect to the JES Job Monitor on port {1} of host {0} Those messages can also be seen followed by this message in the workspace log: !ENTRY com.ibm.etools.zos.subsystem.jes 4 0 2023-06-07 09:29:31.351 !MESSAGE Connection failed because miner com.ibm.etools.zos.jes.miners.JESMiner was not active on remote system. The JMON started task will show both a failed attempt to connect and right after a successful connection attempt. The disconnect was caused by the trusted TCP/IP function in JESMiner when attempting to authenticate a connection to JMON. The recovery logic on a failed attempt sends a disconnect request before the reattempt to connect. The trusted TCP/IP function logic needs to be updated to resolve this. Workaround The following Java property can be added to rse.env: _RSE_JAVAOPTS="$_RSE_JAVAOPTS -DJES_ENABLE_TRUSTED_TCPIP=false" Make sure to recycle to RSED and JMON started tasks so that the change is picked up.

Users are disconnected from remote * * system when JES connection failed * **************************************************************** 1. Users are disconnected from remote system when JES connection failed
Problem conclusion
1. When users are trying to connect JES from client, the client will be disconnected from RSE server when the JES connection failed due to the unexpected client disconnect request sent by the JESMiner. The resolution is to avoid sending client disconnect request when the JES connection fails in JESMiner.
