Migration Mechanics/CICS Processing
If a compile or assemble load proc is specified and the proc invoked is
for CICS, the CICS program pool must be refreshed with the new copy of
the load module. The necessary CICS commands are issued to do this.
However, this can occasionally cause the program to become disabled under
CICS. This may occur if someone is using the program at the same time as
the refresh occurs. Because of this, an attempt is also made to enable
the member. It is possible that both of these may not be enough. If the
member is still disabled, it will have to be manually reenabled.
Automatic refreshing of the program pool only occurs for SCT CICS
programs.
