Port No

shows the TCP port number used in the request.

IP Address

shows the IP address used in the request, if any. If this number shows as

0.0.0.0 when it is a bind, the TSP process will accept incoming connection

requests on any available TCP/IP subnet.

NetIO Open-NoWait Control Block

The following trace record is for Tandem internal use only and shows the starting of a

No-Wait process-file OPEN operation.

04/22/94 11:40:30.740659 >000.024605 #31 No-Wait Open

ONWCB Init File: 3 NIOCB Adr: 3552148 ONWCB Adr: 3552116

Operation

shows the operation performed. In this example, it is the initiation of a No-Wait

process-file open.

File

shows the operating system file number.

NIOCB Adr

shows the address of a control block associated with the I/O operation

ONWCB Adr

shows the address of a control block which maps the file number to the NIOCB

address. This is necessary since No-Wait process-file OPEN operations do not

allow the specification of a “tag” value.
