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. NEWS: The new enhanced Oracle 8 OCI is now supported by DBD::Oracle versions above 0.54. If the new code causes you problems you can build DBD::Oracle for Oracle 8 to use the Oracle 7 OCI by doing: perl Makefile.PL -8 | 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_USERID 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). The new enhanced Oracle 8 OCI is now supported by DBD::Oracle versions above 0.54. If the new code causes you problems you can build DBD::Oracle for Oracle 8 to use the Oracle 7 OCI API by doing: perl Makefile.PL -8 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) Make sure to include the 'stderr' output. The best way to do this is to use the "script" command (man script). If that's not available then (assuming you're not using csh) do "command > command.log 2>&1" The "2>&1" is required (after the stdout redirect) to redirect stderr to the same place. 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.
