QMF used for Oracle report

Question

QMF is tool for DB2 database reports , Can we use this for oracle db reprots? If yes how we can connect QMF with oracle db for reprot generation?

Answer 1

Hi All,
I found Solution for my question
1) Why is there a limit? Why specifically 2 GB?
The 32-bit file handling API used in Reports uses a signed long integer for
addressing into any Operating System file. A signed long integer cannot hold
a value bigger than +2 GB (hex 7FFF,FFFF or decimal 2,147,483,647).
2) Why can Oracle not use 64 bit API calls to fix this, e.g. _lseeki64 on
MS Windows 2000?
_lseeki64 is not available on 32bit Unix Operating Systems, and is therefore
not used. In any case the internals of Reports is built around a signed long
integer as explained already. To make such a change even if _lseeki64 was
available on all 32bit platforms would introduce too big a risk on the
stability of the product.
3) Why can Oracle not just use multiple files of 2gb or smaller, as opposed
to 1 file bigger than 2 GB, for temporary storage?
Oracle has investigated this in the past, and found a negative performance
impact. It is not a trivial change to make, and to maintain performance and
product stability at the same time would indicate a much bigger re-engineering
effort.
4) How does one work around this issue?
Produce several smaller reports as opposed to one monolithic one. This is
generally done by breaking up the run based on parameters. It is a sound
idea to do this in any case, as any failure would mean that the whole
report needs to be rerun. When this happens, it is less of a headache to
rerun a smaller parameterised report.
5) What future plans are there to address this?
Note that our development group has indicated that this is not something
that they hear much about. It would seem that most users follow the
methodology as discussed above.
