procname
The name of a member in a cataloged procedure library. For the servers, this should be the same name specified on the PORT statement in the PROFILE.TCPIP data set.
,PARMS='(CTRACE(xxxxxxxx))'
Used to start an address space that supports component tracing services (CTRACE). Starts the address space with the specified CTRACE initialization PARMLIB member parameters. Some valid values for xxxxxxxx include:
  • CTIRES00 for the Resolver address space
  • CTIEZB00 for the TCP/IP address space
  • CTIORA00 for the OMPROUTE address space
REUSASID=YES
Specifies that MVS™ should assign a reusable address space identifier (ASID) to the address space that is being started. This parameter applies only to the following TCP/IP servers and address spaces:
  • TCP/IP stack
  • Resolver
  • TN3270 server
See z/OS MVS Programming: Extended Addressability Guide for more information about reusable ASIDs.
