Datacom Server mainframe startup failed with errors:
DSV00119E - TCP/IP startup time limit exceeded
DSV00119E - bind failed. errno = 1115, EDC8115I Address already in use.
DSV00120E - TCP/IP startup failed see DSV00119E for cause
Datacom Server running on z/OS and using TCP/IP (PROTOCOL=BOTH or PROTOCOL=TCPIP)
The TCP port specified in TCPIP_PORT SYSIN parameter is already used by another task.
TCPIP_PORT must specify an unused port. Use TSO NETSTAT command to determine which task is using the selected port or to find an unused one.
Examples:
If the command NETSTAT CONN (PORT 1234 returns the following:
MVS TCP/IP NETSTAT CS V2R2 TCPIP Name: TCPIP 08:30:14
User Id Conn State
------- ---- -----
***
then the port 1234 is currently unused.
If it returns:
MVS TCP/IP NETSTAT CS V2R2 TCPIP Name: TCPIP 08:34:32
User Id Conn State
------- ---- -----
SAMPLJOB 001A805F Listen
Local Socket: ::ffff:nnn.nnn.nn.nn..1234
Foreign Socket: ::ffff:0.0.0.0..0
***
then the port is currently used by job/STC SAMPLJOB
The NETSTAT command (with its parameters) can be issued from Sysview using XTSO command (e.g. XTSO NETSTAT PORTLIST or XTSO NETSTAT CONN (PORT 1234 ) or via menus (MENU NETWORK then MENU NETSTAT). Running the command in Sysview is useful when the command returns a long list, such as a list of ports (NETSTAT CONN or NETSTAT ALLCONN), because Sysview produces a list that can be scrolled up and down and can be searched for specific strings (e.g. the port number). The list produced by the native TSO command cannot.
