Use the following queue manager properties pages, or stanzas in the qm.ini file, to specify network protocol configuration parameters. They override the default attributes for channels.
The default value is WCPIC32.
The default value is WCPIC32.
The default value is NETAPI32.
The default is WSOCK32.
When receiving on TCP/IP, a maximum number of outstanding connection requests is set. This can be considered to be a backlog of requests waiting on the TCP/IP port for the listener to accept the request. The default listener backlog values are shown in Table 5.
Platform | Default ListenerBacklog value |
---|---|
Windows Server | 100 |
Windows Workstation | 5 |
Linux(R) | 100 |
Solaris | 100 |
HP-UX | 20 |
AIX(R) V4.2 or later | 100 |
AIX V4.1 or earlier | 10 |
If the backlog reaches the values shown in Table 5, the TCP/IP connection is rejected and the channel cannot start. For message channels, this results in the channel going into a RETRY state and retrying the connection at a later time. For client connections, the client receives an MQRC_Q_MGR_NOT_AVAILABLE reason code from MQCONN and retries the connection at a later time.
KeepAlive=YES causes SPX to check periodically that the other end of the connection is still available. If it is not, the channel is closed.
The default is WSOCK32.DLL.
The default is WSOCK32.DLL.
When receiving on SPX, a maximum number of outstanding connection requests is set. This can be considered to be a backlog of requests waiting on the SPX socket for the listener to accept the request. The default listener backlog values are shown in Table 6.
Platform | Default ListenerBacklog value |
---|---|
Windows Server | 100 |
Windows Workstation | 5 |
If the backlog reaches the values shown in Table 6, the SPX connection is rejected and the channel cannot start. For message channels, this results in the channel going into a RETRY state and retrying the connection at a later time. For client connections, the client receives an MQRC_Q_MGR_NOT_AVAILABLE reason code from MQCONN and should retry the connection at a later time.
