Hi,

can any one tell me whether reboot of server is required while renewing SSL certificate for MQ client or will it apply itself once we replace them with new certificates?

A reboot is not required of the MQ Server.

You say "for MQ Client", so I'm going to assume you are updating the client's certificate and you are doing mutual authentication. I will assume you are (and don't need) to make changes to the Qmgr's certificate or signer.
  1. The client's keystore (I will assume it is also the Trust store) needs the CA that signed the Qmgr's certificate (to talk to the Qmgr at all)
  2. The client's keystore needs the certificate of the CA that signed (or will) the client's certificate
  3. The client's keystore should have the private key from the creation of the "Certificate Signing Request" (CSR)
  4. The client's keystore needs the certificate that the CA signed (using the CSR)
  5. The above items could have been given to you in a *.pfx file
  6. Now here is the trick, if the Qmgr's keystore does not have the certificate of the CA that signed the client, then you need to add it and do the next step
  7. echo refresh security type(ssl) | runmqsc <QmgrName>

Straight up. SSL always works this way. If the client application was running with a connection to the Qmgr, then the client needs to be stopped and started to pick up the new context.
