TM1 SSL Certificate expires end of November 2016
This article addresses to all Longview customers using TM1 as a backend.
On November 24th 2016 the TM1 SSL certificate (Applix) will expire. This means all connections to the TM1 Server will be refused hence causing a perceived major outage. Please check the following link on the IBM support page.
Update Oct. 26. 2016: It turned out that "Option 4" on IBMs "How to update" page may lead into an issue that prevents the Designer and the Server from connecting to the TM1 server via the API interface, as the TM1 API seems to have a problem with the 2048bit encryption of the new certificate. Hence please use "Option 1" for the update of the certificate, no matter which Fix Pack is installed. "Option 1" uses a certificate with 1024bit encryption (same encryption like before) and should be valid for the next ten years too: http://www-01.ibm.com/support/docview.wss?uid=swg21991545
Update Oct. 28. 2016: We found out now that it is possible to force the API to use the new version 2 certificate (2048bit encryption) instead of the version1 certificate (1024bit encryption). Accordingly there will be a revised patch for the Longview Analytics (arcplan) version 8.7 coming next week. This revised version will support a new Longview Analytics parameter that enables to select the version of the certificate the client should use. If version 2 is set in this parameter, the new certificate "tm1ca_v2.pem" mentioned in "Option 4" of the "IBM - How to update" will be used.
