Releasing held data set

When a data set is to be held, JES places the sysout data set on a hold queue until the operator releases it. The system issues no message to tell the operator that the data set is being held. Therefore, when the data set can be processed, ask the operator to release it or release it from a TSO/E userid with a TSO/E OUTPUT command. See z/OS TSO/E Command Reference for information on TSO/E commands.

Examples
//DD1  DD  SYSOUT=C,HOLD=YES

//DD2  DD  SYSOUT=J

//OT1  OUTPUT CLASS=J
//DD3  DD     SYSOUT=(,),OUTPUT=*.OT1

//OT2  OUTPUT DEFAULT=YES,CLASS=J
//DD4  DD     SYSOUT=(,)  

In all these examples, the installation defined class J as a held class during JES initialization.
