Because you're still above the limit, as jefflowrey suggested? Or whatever circumstance caused the 2009 has not yet cleared?
It does tend to be a transient error, but some patience is required. For what it's worth, I tend to code 2009 handleing as 10 attempts 3 seconds apart before giving up and throwing an error.
Purely a personal thing, other error strategies are equally valid, etc, etc.

how to cleaned the 2009 error? but ResonCode is not produced at every MQPUT operation?
you are right. it is a transient error. but MQPUT no block write. if it's return 2009, i must try some times and sleep some seconds? how many times? how many seconds? i want every MQPUT are successful or at least next time. |

Display the queue's attributes. Each of the figures is such an attribute, except total size which can be calculated from current depth but may not be the actual size of the queue file (managed internally by the queue manager).

Then you have a number of options:
1) Manage the number of connections & forked processes as jefflowrey suggested to stay under the limit;
2) Increase the maximum number of allowed connections (this will require the assistance of the administrator and has resource implications)
3) Use a bindings connection not a client one as I have indicated

how to decide i used binding connection or others? use MQCNO_STANDARD_BINDING connect option? my application use MQCNO_HANDLE_SHARE_BLOCK connect option now. and i think MQCNO_HANDLE_SHARE_BLOCK is much fit my use. the fork circumstance. |

It depends on how your program is linked. If it's been linked with the client libraries it'll establish a client connection, if it's been linked with the sever libraries it'll create a server connection.
You'll find this explained in greater detail (along with suggested command line options) in the Application Programming Guide.
The options you mention are for other uses. Check the Application Programming Reference for full details.

If they aren't in the file, then they take the default values.
Which are documented in the System Administration Guide.

i found my program linked the libmqm.so not libmqm_r.so, but i don't know the lib is server or client. i think my program linked server lib.
but if my program re-connect and re-open in sub-process, of course, closed and disconnect the queue after MQPUT operation. the MQCONNX ended with 2059 at some times, but the QManage and Queue name can print at any time. only some times ended with it. i don't know why ?
should my program link libmqm_r.so library? |
