If so, then it's probably either the Redhat PowerPC is a 32-bit version, or

Are you updating anything on login, either unix or uv? Are the .profiles
doing any serious processing? It's hard to tell how far it got just from the
display. Does the process show up in PORT.STATUS before you kill it?

interprets this as "the system is crashing", and attempts to clean up
everything it can before exiting. Kill -9 means sudden death, no getting

Add to this the fact that, given the usual page size of 4k, you're going to

You may want to look at UV Replication using publisher/subscriber instead.
If you have a transaction (update) that crosses the boundaries of one

If your scripts do not somehow take account of transactions that span across
2 logs, this will drop transactions.

Ah, the transaction logger.
Here's the problem (unless it got fixed somehow) with that:
When you're running uvrolf to roll forward the logs on the DR box, you have
the "last transaction" problem. The last update in the transaction log can
span over to the next transaction log. If this happens (an
I'd be worried about a particular vulnerability in this scenario.
If the system goes down while you are updating overflow or oversized data
frames, you could get file corruption. A single U2 logical write can take
multiple os writes, and at any given moment on a busy system, you probably

Of course, there are a lot of things to look at.
I think what you're looking for is svmon -U username. This will show you the
user's memory map. Svmon with no arguments shows you overall stats; one
thing to look for there is that there should be no pinned memory for UV;
Oracle needs pinned memory,
Right. The readnext id is against the open file - you're not reading the
actual item (that's in the "CODE"). If you're not doing it this way, compare
a benchmark for this with whatever you're using. I think you'll see that
this construct uses many fewer system calls, reads, and cpu cycles.
