Hello sages

Having read that MultiSystem is a no-charge option in 7.5 I would very much
like to test table partitioning and hopefully use it.
Rational:
We heavily use Multi-Member-transaction-Files, Physical & Logical (several
hundreds files)
Some such files have hundreds MBRs and a few over a thousand.
These files are managed by ADDPFM / ADDLFM / OVRDBF and such.
This is nice and dandy for day to day operations but makes for a difficult
task querying
and analyzing historical data.
So we regularly copy those files to a Single-MBR DataWarehouse-like files
adding the Member Name as a field (and a key) and use those DWH files for
historical analysis.

Several questions come to (my) mind when considering replacing it with
table partitioning:

1. How many partitions are allowed in a partitioned table or index?
2. After a partitioned table is created, can one use
ADDPFM/RMVM/CLRPFM/ADDLFM on it ?
(I've read that OVRDBF works with it)
3. Is there a performance penalty that comes with partitioned tables ?

All answers will be thankfully received.
