time to install a QK1123 bundle

[Frédéric DAMEZ]

I have to install the bundle QPK1123(B.11.23.0706.064) with included bundle QPKAPPS and QPKBASE on a rp4440 (4 processeurs,20GB of RAM).
I have to prevent the users to stop the machine but I have to estimate the time to install the bundle.
Please can you help me.

Hi,

Total time to install a patch bundle is depends on how long your system take to boot up. With 20 GB of RAM, I guess it will take about 20 minutes each reboot. If you request 1 hour of downtime, it should be enough for a spare time.

Hello Fred,

Firstly - make_tape_recovery & full system backup :)

>> I have to estimate the time to install the bundle

It depends, worst scenario, unable to regen kernel, unable to boot to previous kernel & need to recover from backup tape.

Please estimate more server downtime hours if necessary.

Thanks

If everything goes OK, then an hour might just make it. NEVER, EVER give an estimate without adding 2-3 hours for problem resolution. You tell everyone it will be a 4 hour outage and when you are back up and running after 2 hours, everyone is happy. But if you estimate an hour and need to reboot a couple of more times to solve a local configuration issue, everyone will be mad at you when it takes another hour.
