$E MEMBER command start

In addition to the above method of restarting JES2, a restart of work on the failed member can be performed on any other active member in the configuration by the AUTOEMEM facility or by entering the $E MEMBER command. In-process work on the specified member is recovered and made available for selection by other members of the configuration, subject to affinity for execution restart.

The following table summarizes the type of start performed in a given environment and situation when you request a warm start. In the table, “JES2 Terminates Normally” infers that the operator enters a $P JES2 command; “JES2 Terminates Abnormally” infers that the operator enters a $P JES2,ABEND[,FORCE] command or JES2 terminates abnormally.

Table 1. Types of JES2 Warm Start
Environment:	JES2 Terminates:
Environment:	Normally with IPL	Normally without IPL	Abnormally with IPL	Abnormally without IPL
First member starting (single member or MAS complex)	All-member warm start	All-member warm start	All-member warm start	Hot start
Another member joining an already-running MAS complex	Quick start	Quick start	Single-member warm start **	Hot start *
* Assuming no $E MEMBER from another member. If $E MEMBER was issued, a hot start will be denied ($HASP490) and an IPL is required. ** Assuming no $E MEMBER from another member (or AUTOEMEM option) from another member. If $E MEMBER was issued, a quick start results.
