Fault messages
An abnormal condition within GDSX can generate a number of different messages. For
example, a trap can generate a fault message at the EMS terminal, and a trap message
and an abend message at the home terminal.
EMS messages generated by converted GDSX processes always show the PIN with a
value of 255.
Startup Configuration Error Messages
These messages may be generated by GDSX during data space initialization. At GDSX
process startup, TSCODE calculates the space required in extended memory for each
type of control block. Only after all calculations have been completed are allocations
done for the control block pools. Equations for these calculations are given in
Figure 2-2 on page 2-21. Calculations are made in the following order:
Generally, it is not necessary to override the size that TSCODE calculates for a pool, but
it can be overridden either by using a TACL PARAM command to assign a value to the
configuration parameter’s external name, or by assigning a value to a configuration
parameter’s internal name in the USER^INIT^CONFIG^PARAMS user exit. The
external names are:
MAXTCBPOOL
MAXIOCBPOOL
MAXRCVPOOL
MAXRCBPOOL
MAXFCBPOOL
MAXDCBPOOL
MAXLDCBPOOL
TCB Task control block
IOCB I/O control block
RCV Receive control block
RCB Requester control block
FCB File control block
DCB Device control block
LDCB Logical device control block
LCB LINE control block
