It took us less than 45 minutes for the upgrade from 5.2.3.1 to 5.4.0.3.
Our database is nearly 470GB although it's currently at 28% utilized (yes,
I know, it's a long story...), and runs on a P650.

Of greater concern is that the performance at the new code does not seem
to be as good, in a rather vague and intermittent way.  We are seeing
behavior that suggests that it's not always releasing network
communications properly, but not all the time and not for all
communications.  We have not seen this in either of the two much smaller
environments that it's been installed on.  So if you have a lot of
connections on a daily basis, you might start seeing some impact.  We've
opened a ticket to IBM

I would love to know if you (or anyone else) see any behavior differences
over time at 5.4.  I haven't seen much here in the way of complaint but I
don't know if that means it's really great stable code, or if there just
aren't many people using it yet.  Or both, and we're flukey.  :-)

Subject
upgrade of 200 GB DB






I am planning to upgrade my 200 GB TSM 5.2.6 Database to 5.4

  Does anyone have any estimate on how long that will take?

  I do realise there are many other variables but wondering how long it
will take roughly.

  TSM log is 12 GB

  My LPAR is a P550 with 4 CPUs and 10 GB of memory.

  thank you in advance.
  Daad
