README

DBD::Oracle  --  an Oracle 7 and Oracle 8 interface for Perl 5.

   Copyright (c) 1994,1995,1996,1997,1998  Tim Bunce, England.

   You may distribute under the terms of either the GNU General Public
   License or the Artistic License, as specified in the Perl README file,
   with the exception that it cannot be placed on a CD-ROM or similar media
   for commercial distribution without the prior approval of the author.

   PLEASE READ THE ENTIRE README FILE CAREFULLY !


WARNING:

   THE DBD::Oracle MODULE IS ALPHA SOFTWARE. It is *only* 'Alpha'
   because the interface (api) is not finalised. The Alpha status does
   not reflect code quality or stability.

|  NOTE:
|  The only currently supported interface is via Oraperl.pm, the        |
|  oraperl emulation layer. This is fairly complete and stable.         |
|  Execute "perldoc Oraperl" after installing for full information.     |


*** QUICK START GUIDE:

    The DBI requires one or more 'driver' modules to talk to databases.
    Fetch, build and install the DBI module as per it's README file.
    Then delete its source directory tree since it's no longer needed.
    Use the 'perldoc DBI' command to read the DBI documentation.
    Fetch the DBD::Oracle driver module and unpack it.
    Follow the guidelines in this README file caefully.


*** *BEFORE* BUILDING, TESTING AND INSTALLING this you will need to:

    Build, test and install Perl 5 (at least 5.003, preferably
    version 5.004_01 or later).
    It is very important to TEST it and INSTALL it!

    Build, test and install the DBI module (at least DBI 0.86).
    It is very important to TEST it and INSTALL it!

    Remember to *read* the DBI README file and this one CAREFULLY!

    Install enough Oracle software to enable DBD::Oracle to build.
    That usually includes Pro*C.


*** BUILDING:

    perl Makefile.PL            # use a perl that's in your PATH
    make

If you have problems see the 'IF YOU HAVE PROBLEMS' section below.
If it's builds without error you can then run the tests. For the
main test to work it must be able to connect to an Oracle database.

Don't worry about most warnings, specifically "end-of-loop code not
reached", "ANSI C forbids braced-groups within expressions", "cast
increases required alignment of target type" and "passing arg 2 of
`oerhms' with different width due to prototype".

You will need to set either the TWO_TASK or ORACLE_SID environment
variables to the correct values for your database. Consult Oracle
documentation for more details. Test your setting by connecting to
the database using an Oracle tool such as sqlplus. Once you can do
that then you can test DBD::Oracle knowing that it should work.

The supplied test will connect to the database using the value of the
ORACLE_USER environment variable so you should set that to the correct
value before starting the test. Please read README.login.

    make test

    make install (if the tests look okay)


*** IF YOU HAVE PROBLEMS:

Make sure you are using a recent perl 5.003 or preferably 5.004 and
make sure it's on your path so you can say 'perl Makefile.PL' and
not '/path/to/perl Makefile.PL'.

If you have build/link or core dump problems try:
	perl Makefile.PL -p
If it helps then please let me know (and please include a copy
of the log from the failed default build, the log from the build that
worked, plus the output of the "perl -V" command).

Do not hand edit the generated Makefile unless you are completely sure
you understand the implications! Always try to make changes via the
Makefile.PL command line and/or editing the Makefile.PL.
You should not need to make any changes. If you do please let me
know so that I can try to make it automatic in a later release.

If you just can't login or login takes a long time then read
README.login and possibly edit test.pl to suit.

If you can't get it to build on a minimally configured client system
then read README.client, it might help but basically I can't help much.
Others on the dbi-users mailing list probably can.

If you have linking problems (errors related to libraries or functions)
then you could try forcing a 'static' build using:

  make realclean
  perl Makefile.PL LINKTYPE=static
  make
  make perl       (you'll need to use and install _this_ new perl binary)
  make test
  make -f Makefile.aperl inst_perl MAP_TARGET=perl  (install new perl)
  make install                                      (install DBD::Oracle)


>>> Also carefully read the README.help file which is full of useful
>>> tips and workarounds for various problems of various systems.


*** HOW TO REPORT PROBLEMS

Please don't post problems to comp.lang.perl.* or perl5-porters.
This software is supported via the dbi-users mailing list.  For more
information and to keep informed about progress you can join the
mailing list via http://www.fugue.com/dbi (if you are unable to use the
web you can subscribe by sending a message to dbi-request@fugue.com, it
may take a few days to be processed).

Please post details of any problems (or changes you needed to make) to
dbi-users@fugue.com and CC them to me at Tim.Bunce@ig.co.uk. But note...

** IT IS IMPORTANT TO INCLUDE *ALL* THE FOLLOWING INFORMATION:

1. A complete log of all steps of the build, e.g.:

    (do a make realclean first)
    perl Makefile.PL -v        (note the -v for verbose)
    make
    make test
    make test TEST_VERBOSE=1   (only if any of the t/* tests fail)

2. Full details of which version of Oracle you're using (if it
   wasn't automatically found and printed by "perl Makefile.PL")

3. The output of perl -V       (that's a capital V, not lowercase)

4. If you get errors like "undefined symbol", "symbol not found",
   "undefined reference", "Text relocation remains" or any similar
   error then include the output of "perl Makefile.PL -s XXX"
   where XXX is the name of one of the symbols.
   Please don't send the entire output of this command,
   just any obviously 'interesting' parts (if there are any).
   See also the LINKTYPE=static notes above.

5. If you get a core dump, rebuild DBD::Oracle with debugging
   enabled by executing: perl Makefile.PL -g  (note the -g option)
   then rerun the code to get a new core dump file, finally use a 
   debugger (gdb, sdb, dbx, adb etc) to get a stack trace from it.
   NOTE: I may not be able to help you much without a stack trace!
   It is worth fetching and building the GNU GDB debugger (4.15) if
   you don't have a good debugger on your system. If desparate try:
     make perl; ./perl script; echo '$c' | adb ./perl core

6. If the stack trace mentions XS_DynaLoader_dl_load_file then rerun
   make test after setting the environment variable PERL_DL_DEBUG to 2.

It is important to check that you are using the latest version before
posting. If you're not then I'm *very* likely to simply say "upgrade to
the latest". You would do yourself a favour by upgrading beforehand.

Please remember that I'm _very_ busy. Try to help yourself first,
then try to help me help you by following these guidelines carefully.
And remember, please don't mail me directly - use the dbi-users
mailing list.

Regards,
Tim.
