Hello forum members,
My team has started working on Websphere MQ recently. We are queried by network team in project about the type of TCP connections made when JMS application connects to Websphere MQ server.
I would like to know if it uses Persistent TCP IP connection or it uses normal TCP IP connection which will be terminated after some time.
We are using Publish - Subscribe model for communication with MQ server.
I tried to search on the internet, however, could not get exact answer for this.
Requesting your help on this.
Thanking in Advance,
Regards,
Ani |

MQ functions as a resource to your application.
So you need to acquire the resource... and you need to EXPLICITLY release the resource.
Hope this answered your question.

MQ uses the standard TCP IP Socket APIs. Socket sessions in MQ would normally be expected to terminate / close after some time. Eg. A channel is no longer running, or a client disconnects.

What do these terms "persistent" and "normal" mean.
A TCP/IP connection is a TCP/IP connection. There are not 2 types.
MQ uses a TCP/IP connection. |

I also never heard about persistent or normal TCP/IP connections. With WMQ you may configure channels in such a way, that the never end. But in general the will have a disconnection interval which causes the channel to stop the connection after a while. Does this mean "persistent" or "normal"?
MQ channels also use heart beats to keep a channel - and its corresponding IP connection - open. But when the disconnection interval has reached, the channel will stop either.
Maybe this answers your question?
