Hi,
What does it means when i see SDR channel retrying and substate is OTHER.?
After that I tried to restart the sender channel, it goes to SSL handshaking substate and then goes to OTHER again.
What are the possible causes ?
I have another similar channel with similar SSL parameters but it manage to establish with the receiver after a long time. I have turned off OCSP in qm.ini, but that doesn't seem to help.
thanks |

hi, thanks.
At the sender channel QMGR, the error is amq9259 , connection timeout.
At the receiving QMGR logs, there was nothing logged.
However, at the sending QMGR , they are able to make a telnet connection to receiving QMGR. |

Hi
Have you checked the listener status on the receiver side Qmgr ? |

yes, the listener is fine. Or do you mean there is some special attributes that i should take note of for a listener?
thanks |

Hi, the strange thing is the channel will be established several minutes later. There are no SSL errors in the logs at both ends. |

Hi
so it will be interesting some additional investigation on the behavior ,for example if we use a no ssl channel between the two qmgr do we measure similar connection times ? |

without SSL seems to be normal. but with SSL, it takes longer to get established. |

Hi
so the issue may be in the ssl handshake process ,a good clue could be the lenght of the keys ,the level of crypt you require ,and last but not the least the network bandwith ... |

Please help us understand this better.
Are you saying that without SSL the channels enter RUNNING state immediately, but with SSL it takes a few seconds longer? One minute longer? Five minutes longer?
Is this your first or only SSL channel? Is this behavior limited to only one SSL channel? Or is this behavior consistent for all SSL channels?
