Hello all!
I am experiencing a problem: whenever I start a listener to TCP port with five digits (ex. 10000) I receive a CSQX218E message with RC=0000045B. I've tried to start 9999 TCP port successfully.
Does anyone have any clue about it???
Regards,
Luis Henrique.

Hi,
all my queue managers are running on ports bigger then 10000.
I found the following on the internet
| Quote: |
| CSQX218E +QWP1 CSQXLSTT Listener unable to bind to port 1414 address .0.0.0, TRPTYPE=TCP INDISP=QMGR, RC=0000045B |
Maybe your port is used by another application. Or some other mechanism is prohibiting your listener to bind to that port?!
Is there anything meaningful in your logs (the MQ ones, or maybe even the system logs)? Any FFST files?
my 2 cents

Hi,
I've verified that I can't start listener TCP port range from 10000 to 11999. I managed to start the listener TCP port from 12000 to above. Looking at the z/OS TCPIP profile dataset, there is no reserved ports in that range. Also, there is no application usging them.
It could be a restriction of MQSeries, or it could be a Channel Initiator parameter that not allow to use ports from that range???
Regards.

Hi,
I am almost certain, that MQ itself is supporting any TCP port you want.
Also I have tested it on Windows and on AIX. It is working for me.
Don't really knowing z/OS, but is it possible that there is a limitation of z/OS?
cheers

Hi,
in z/OS is possible to reserve ports, but as I told before, I've already verified it (in profile TCPIP), and the range (10000 - 11999) is not reserved. So, I guess the problem could be in MQSeries.

it does appear that the port/address is in use.
what version of MQ are you on?

Hello.
I've just discovered the reason of the problem. There is a component in z/OS, called Unix System Services (USS), where the stack TCPIP of z/OS is running on. So, there are two parms in USS that reserve ports: INADDRANYPORT that specifies the starting port number to be reserved, and INADDRANYCOUNT that specifies how many ports to reserve. These parameters are specified in member BPXPRMxx that resides in SYS1.PARMLIB dataset. In my case, the INADDRANYPORT value is 10000 and the INADDRANYCOUNT value is 2000.
Tanks for your help!
Regards.
