Timeout of the EPI request

There are two EPI timeout conditions, install timeout and read timeout.
Install timeout
Install timeout is the maximum length of time that the CICS® Transaction Gateway or CICS Universal Client will wait for a terminal to be installed on a CICS server. If a response is not received from the server within the specified time, control is returned to the user application with an appropriate return code. If the Client daemon is subsequently notified that the terminal has been installed in the server, the Client daemon deletes the terminal. If no install timeout value is specified, there is no limit to the wait time.
Read timeout
Read timeout is the maximum length of time that the CICS Transaction Gateway or CICS Universal Client will wait for a response from the user application. This period of time starts when a user application has received an EXEC CICS RECEIVE or CONVERSE command issued by CICS. A read timeout occurs if no data is returned before the period specified has elapsed. If no read timeout value is specified, there is no limit to the wait time. When a read timeout occurs, the transaction on the CICS server is terminated abnormally.
