In response to a RELEASEWS command, ANTMAIN has released serialization on the named working space data set. This allows other operations on the data set to be performed.
VCC operations continue, but this data set is not used for working space. If insufficient space is available in other working space data sets, jobs using VCC might fail. The data set remains unused until the MODIFY ANTMAIN,REFRESHWS command is issued to re-enable usage, the ANTMAIN address space is restarted, or an IPL is performed on the system.
If message ADR736E occurs with a return code indicating insufficient space is available, allocate additional working space data sets or restore access to the data set that was released. Then use the REFRESHWS modify command to enable the data sets for use by ANTMAIN.
