Hello,
I'm testing the example the its on the IBM site, but I get this error:
node[6712]: pthread_create: Resource temporarily unavailable
module.js:478
throw err;
^
Error: Cannot find module 'ibmmq'
at Function.Module._resolveFilename (module.js:476:15)
at Function.Module._load (module.js:424:25)
at Module.require (module.js:504:17)
at require (internal/module.js:20:19)
The server admin tells me that the IBMMQ it is install.
This is the code:
mq = require('ibmmq'); // import the package containing the MQI library
MQC = mq.MQC; // refer to constant values exported by the package.
mq.Conn("CRI400F", function(err,hConn) {
if (err) {
console.log(err);
} else {
console.log("MQCONN successful ");
// Define what we want to open, and how we want to open it.
od = new mq.MQOD();
od.ObjectName = "CL.LCRBA.SRV.RESPUESTA.SVU";
openOptions = MQC.MQOO_OUTPUT;
mq.Open(hConn,od,openOptions,function(err,hObj) {
if (err) {
console.log(err);
} else {
console.log("MQOPEN successful");
}
});
}
});
msg = "Hello from Node at " + new Date();
mqmd = new mq.MQMD(); // Defaults are fine.
pmo = new mq.MQPMO();
mq.Put(hObj,mqmd,pmo,msg,function(err) {
if (err) {
console.log(err);
} else {
console.log("MQPUT successful");
}
}); |

The Node.js package is not part of the IBM MQ install. Read the link I provided before which contains where to find the Node.js package.
Cheers,
Morag

Hi hughson
he error is not with the Nodejs, If I run this the error is
Error: Cannot find module 'ibmmq'
If in the server there is a MQServer install and not clients, will this cause the error? |

I don't think Morag could have been clearer. If you only have the standard IBM MQ install, that doesn't contain the JavaScript component.
Read the link provided once more. Or once. And if you've followed the directions to install the JavaScript package, post exactly what you did and exactly what happened when you did each step.

This is the code:

I'm sorry my statement wasn't clear. When I said the Node.js package, I was refering to the ibmmq package which you are endeavouring to import in your code. This package, called ibmmq, is a Node.js package. This package is not part of the IBMMQ installation. You can find the link to download this Node.js package called ibmmq from the document I referred you to earlier.
Hope this makes it clearer for you.
Cheers,
Morag

| The ibmmq package is integrated with the standard npm repository manager in the same way as all other Node.js packages. So you can either install it explicitly, or implicitly via the package.json file associated with your program. |

It may require an installation of the mqclient libraries. If you don't have those installed, you may just be SOL.
