Hi,
I have got a problem with resizing the bufferpool of a DB2 v.8.2
instance.
The DB2 runs on an AIX 5.x platform.
Problem is that an "ALTER BUFFERPOOL ..." command is not persistent if
the database is stopped with the db2stop and restarted with the
db2start command.

Folks,
I am not sure what I am doing wrong, but We have an transaction that
does some serious calculation on small chink of data over and over
again.
It selects few rows from the table several times and does different
calculations. It was taking about 45 seconds to run. I thought that
moving the file to its own tablespace and giving it large bufferpool
would improve the performance. I experienced exactly opposite, the

HI Every body ,
I would like to know whether is it mandatory to give Tablespace page
size and Bufferpool page size equal..? i also heard like while creating
tablespace if pages size of tablespace and bufferpool , the statement
itself will fail ...why i'm asking is if we chose a different page size
( ofcourse less than bufferpool page size ) only it shoud affect the
performance of db2 ..
Thanks in Advance

hello,
admin guide says that
pool_data_p_reads - pool_async_data_reads will give me number of
physical reads that were performed synchronously (that is, physical
data page reads that were performed by database manager agents).
I assume then pool_data_p_reads should give total value of all reads
( synchronous + asynchronous )
i see values for pool_async_data_reads more than pool_data_p_reads in

In 9.1 and 9.5 (Linux 64 bit) when a buffer pool is set to self-
tuning, how are blocks configured in respect to blocked vs non-blocked
when self-tuning is set to on?
(ie) I have one bufferpool that is 16k that the IBMDEFAULTBP is shared
between all tablespaces.
The data tablespace has prefetch automatic set to on.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
