  • 1.  14.10.FC7 Upgrade Issues/Warning

    Posted 9 days ago

    All:

    Just completed some development environment upgrades to 14.10.FC7 (from FC6) and hit on a couple of issues you should be aware of.

    First, as noted in other threads, the MIRROR parameter has been deprecated and the engine setting is now always on. So if you weren't previously using it and had left the MIRRORPATH to a default setting, you need to clear that field out or it's going to barf.

    Second, we've got some microservice type processes that connect to our databases pretty aggressively, with fairly rapid retries. On two different instances, these processes constantly trying to connect somehow munged the SMI rebuild that happens as part of the upgrade process. This caused the engine to get stuck in single-user mode and the sysmaster database to be inaccessible. The workaround (for me) was to comment out DBSERVERALIAS and edit sqlhosts to change the port for DBSERVERNAME to an unpublished one before running the upgrade. You could also put a firewall block on the main port. Once I did this, the upgrade completed quickly and without incident.

    Hi there,

    thanks for the feedback - we´re planning to upgrade from FC3 to FC7 directly - do you think its better to do a step in between? FC3 > 6 > 7 ?

    Go direct - unless you are using ER I can't think of any additional issues

    Cheers

    Agree with Paul. Direct should be fine.
