Is it possible to use MQ PCF APIs to get the expiry date of the SSL Certificate installed for a Channel on a Queue Manager ?
From a Systems Management perspective, is it possible to get advance notification in cases when a SSL certificate of a MQ Queue Manager is going to expire in the next say 5 days ?
In order to get that I was thinking of writing a custom code. But, I am not sure if using MQ PCF APIs I will be able to get the expiry date of the SSL certificate on a QM channel. |

| No, the expiry date is an attribute of the certificate, not the channel. |

And please note that queue managers have certificates, channels do not have certificates (although it would be nice to have).

Thanks a lot for the replies.
I know that I can use PCF APIs to get the file path of the certificate key repository for a queue manager. After I get that, do I have any MQ Java / PCF API to which I can give this path and it would return me the expiry date of the certificate present in that key repository ?
Similar thing is possible using the gskit tool that is available with MQ installs.
C:\IBM\WMQ\gskit\ibm\gsk7\bin>gsk7cmd -keydb -expiry -db c:\IBM\WMQ\qmgrs\QM1\ssl\key.kdb -pw xxxxx
I want to do this thing using Java. Is that possible ? |

It may be possible to do things in Java to enquire about a certificate from a keystore.
It is not possible to do this using any MQ APIs, in Java or otherwise. There is no MQ API that will do this.
You may also find it somewhat challenging to read certificates that are not kept in a Java KeyStore (jks) file from a Java program. |

Also note that it is against security guidelines to allow just anybody to retrieve that information. Retrieving that information using MQ is equivalent to an anonymous access...

Certificates, the keystore and other ssl thingies are part of a service (like LDAP, for example), and are not mq objects. Therefore, the MQI calls do not apply.
SSL implements its own set of APIs. Do a quick google search for ssl+api.

understand.. appreciate the replies...
here is the scenario that I face...
we have a bunch of MQ Queue Managers (>100 ...most on windows machines) ...Many of them have SSL Certificates installed in them for inter Queue Manager connections or client connections. A major issue we face is that such certificates expire and we come to know of that only when there is a connection failure due to certificate expiry on a Queue Manager.
You must have guessed : We need to have automated advance notifications.  Any ideas on how I can get advance notifications of expiring QM SSL certificates ?
I was considering writing a script...
Each Queue Manager has the SSL configured with the path provided to its key database file (kdb file). The kdb file contains the SSL certificates for that QM.
In my case, for many of the Queue Managers the path where the key database file (kdb) file is stored is actually a mapped drive on that windows machine.
The gsk7cmd command can give me the expiry date of a certificate which resides inside a kdb file. I would like to execute this command on a central machine and give it the path to the kdb files of various QMs in sequence. Would this work ? My problem is that this command is not accepting a path which looks like \\anothermachine\g$\somefolder\ssl\key.kdb.... Any ideas ?
Thanks... |

Your script could define as local drive y
| Code: |
| net use y: \\anothermachine\g$ |
The rest is then up to you to attach / detach the drive and use gskit to determine certificate expiration date.
Have fun...
