NOTE:
This release has major changes to Unicode support. See below.

and package compilation errors.
Added automatic support for UTF-8 for both NLS_LANG and NLS_NCHAR
Many thanks to Lincoln Baxter who did most of the hard work and testing

=head1 Changes in DBD-Oracle 1.15 27th January 2004
NOTE: DBD::Oracle now requires DBI version 1.28 (June 2002) or later.
NOTE: This is probably the last release that will support being
built with the old Oracle 7 OCI interface.
NOTE: This release will build for perl 5.5 only after some manual edits
which are detailed in README.help. Future releases may not build for 5.5.
Perl 5.5.3 is very old and and upgrading to at least 5.6.1 is recommended.
The DBI itself has required perl >= 5.6.0 since DBI 1.38, August 2003.
Fixed Makefile.PL for HPUX thanks to H.Merijn Brand & Sweth Chandramouli.
Fixed Makefile.PL for handling 32/64bit libs thanks to Lincoln Baxter,

Fixed bind_param_inout() for placeholders not assigned to in PL/SQL.

length of 28 characters. Warning: this change may break code that
doesn't pass bind_param_inout() a length value large enough for the
returned string. (The minimum length was not documented and should
not have been relied upon. This change currently only applies to the
CHAR type but may extended to all string types in a later release.)
Changed type_info_all() to return the same type info as Oracle's own
ODBC driver does, thanks to Andy Hassall for the data.
The types include LOBs but not the new TIMESTAMP and INTERVAL types.

Added t/ph_type.t to test placeholder type issues thanks to James Jurach.
Retested for perl 5.4.4 for possibly the last time. You have been warned.
In future I'll only be testing on perl >= 5.5.3 and >=5.6.1.

Updated Makefile.PL and README.hpux thanks to Lincoln Baxter.
=head1 Changes in DBD::Oracle 1.07 5th June 2001
This release is mostly targeted at the needs of the new Oracle::OCI module.
It's not a general release and not recommended for production use.
Fixed SCALE/PRECISION/TYPE values for numeric types, including FLOAT,
to be more correct thanks to Steffen Goeldner.
NOTE: this may break code that depends on the old values!
Fixed Win32::TieRegistry and Tie::Registry usage thanks to David Bradford.

=head1 Changes in DBD::Oracle 1.06 14th July 2000
Fixed ora_ph_type attribute to allow 96 or 97.
Fixed compile failure with Oracle 7.
=head1 Changes in DBD::Oracle 1.05 13th July 2000
Added $dbh->{ora_ph_type} attribute to define default bind type:
1=> VARCHAR2, does strip trailing spaces, embedded \0 bytes okay
5=> STRING, doesn't strip trailing spaces, embedded \0 ends string
96=> CHAR, doesn't strip trailing spaces, embedded \0 okay
97=> CHARZ, doesn't strip trailing spaces, embedded \0 ends string?
The two CHAR types force 'blank-padded comparison semantics'.
Needs testing and documenting, volunteers most welcome!
Added (many) typecasts to avoid compiler warnings thanks to Denis Goddard.
Added ability to pass existing DBD::Oracle select statement handle
(cursor) back _into_ Oracle as a ref cursor type thanks to Mike Moretti.

=head1 Changes in DBD::Oracle 0.61, 9th April 1999
Fixed execute() always returning 0 rows! (with OCI 7).
Fixed $sth->bind_param(..., SQL_CHAR);
Assorted minor Makefile.PL improvements.
Added ora_check_sql attribute to prepare() for OCI8.
=head1 Changes in DBD::Oracle 0.60, 10th March 1999
Fetching all records now resets Active flag as it should.
Finally fixed "Can't bind unknown placeholder" (hopefully :-).
Fixed placeholder parser to ignore comments, thanks to JD Laub.
Fixed placeholder parser to ignore double-quotes strings.

(previous fix had typo). Only affects multiple LOBs in same table.
Added support for Oracle 8's "... RETURNING foo,bar INTO :foo,:bar"
for simple scalar types (not LOBs or arrays) via bind_param_inout.
Cleaned up the code.
Improved Oracle 8 library selection code for Win32 (untested).
=head1 Changes in DBD::Oracle 0.58 (Oraperl 1.37), 22nd December 1998
Fixed detection of ambiguous LOB-param-to-table-field assignment.
Added bind_param ora_field attribute to disambiguate if needed.
=head1 Changes in DBD::Oracle 0.57 (Oraperl 1.37), 21st December 1998
Fixed bug preventing fetching LONGs when using OCI 8, better.
(Oracle bug #641812 not involved. Should work for all 8.0.x)
=head1 Changes in DBD::Oracle 0.56 (Oraperl 1.37), 19th December 1998
Fixed bug preventing fetching LONGs when using OCI 8.
(Oracle bug #641812 may still cause failure prior to v8.0.5.)
Fixed LongTruncOk to work when using OCI 8.
Fixed bug in table name detection code for OCI8 LOB refetch.
SCALE & PRECISION work for OCI 7 & 8.
=head1 Changes in DBD::Oracle 0.55 (Oraperl 1.37), 16th December 1998
Major internal work to support Oracle 8 OCI.
Oracle 8 LOBs are supported and treated as LONGs (DBD::Oracle works
hard to hide the complexities of handling Lob Locators for you).
See Oracle 8 section in the docs for more details.
Added $sth->{TYPE}.
SCALE & PRECISION are implemented but return 0 (Oracle bug?).
DBI 1.02 or later is required.
Assorted build time Makefile.PL improvements.
Builds with 5.004_04, 5.005_02 and 5.005_54 (not _53).
Added "use DBD::Oracle qw(:ora_types);"
=head1 Changes in DBD::Oracle 0.54 (Oraperl 1.37), 14th August 1998
Added $dbh->type_info_all.
Fixed $dbh->tables (partly by renaming to new $dbh->table_info).
data_sources no longer adds abbreviated versions of tnsnames.
Alan Burlison's whizzo Tk based explain script now bundled.
Revised workaround for "Can't bind unknown placeholder '3'" errors.
Doubled default automatic row cache size (now approx 5KB).
The resetting of Oracle's SIGCHD handler to SA_RESTART can
now be disabled by setting the env var DBD_ORACLE_SIGCHLD=0.
Fixed Makefile.PL -c to better avoid shared Oracle lib.
=head1 Changes in DBD::Oracle 0.53 (Oraperl 1.37), 3rd August 1998
Further build fixes (esp kpudc problem with Oracle 8).
Now prefers oracle.mk over proc.mk again.
Only $ENV{ORA_CLIENT_LIB} ||= 'shared' if shared lib exists.
Builds okay with 5.005-thread (not tested).
=head1 Changes in DBD::Oracle 0.52 (Oraperl 1.37), 28th July 1998
Assorted build fixes (esp. Win32, HP-UX and AIX).
More hints on error messages, especially long truncation and
field-level errors when fetching.
Compiles okay now for systems without SQLT_CUR defined.
Only sets SA_RESTART on SIGCLD if connect was successful.
=head1 Changes in DBD::Oracle 0.51 (Oraperl 1.37), 5rd July 1998
Makefile.PL no longer tries to link with just -lclntsh directly :-(
Improvements to some HP-UX builds (hopefully).
DBI->data_sources ' dummy ' value removed (and list now sorted).
connect failure now shows actual Oracle error message again.
Initial (incomplete) support for binding cursor vars (see t/plsql.t).
=head1 Changes in DBD::Oracle 0.50 (Oraperl 1.36), 3rd June 1998
Makefile.PL changes: fixed -c option, now searches for .h files,
tries alternate location for sysliblist, checks for executable
orainst/inspdver before using it.
Fixed cursor leak.
Added first word of tnsnames.ora name as aliases if no clash.
=head1 Changes in DBD::Oracle 0.49 (Oraperl 1.36), 1st June 1998
Further improvements to build process over 0.48.
Fixed broken truncation error in 0.48.
Fetch ORACLE_SID from Win32 registry (thanks to Preston Bannister)
Improved automatic row cache sizing (prompted by Jon Meek).
Added $sth->{ora_cache_rows} and $sth->{ora_est_row_width}
as read-only attributes to make cache size logic easier to test.
=head1 Changes in DBD::Oracle 0.48 (Oraperl 1.36), 25th May 1998
THIS IS AN EXPERIMENTAL RELEASE - USE WITH CAUTION!
Now links to -lclntsh directly (Thanks to Bruce Nelson and others)
Workaround for broken backticks after login (Thanks to Warren Jones)
Now finds and reads tnsnames.ora to disambiguate dbnames in connect.
Added basic support for bind_param(..., SQL_TYPE).

Requires DBI 0.92
=head1 Changes in DBD::Oracle 0.47 (Oraperl 1.35), 8th Sept 1997
$h->{InactiveDestroy} = 1; now works reliably (with DBI 0.90).
Makefile.PL changed for Oracle8. Thanks to Philippe Vanhaesendonck.
Long params now work. Thanks to Michael Harvey.
(Long params don't yet work for inout params.)
AutoCommit flag now per-dbh. Thanks to Irving Reid.
Fixed panic: _dbd_rebind_ph when binding an undef.
Added $dbh->ping method (for Apache::DBI users).
Some field-level fetch errors didn't cause the fetch to fail
(the field was simply set undef).
LongReadLen now works (if $Oraperl::ora_trunc unset or <= 0)
LongTruncOk now works (for non oraperl mode handle).
=head1 Changes in DBD::Oracle 0.46 (Oraperl 1.34), 20th June 1997
Fixed Makefile.PL to work with 5.004_01.
Some VMS support from Dan Sugalski <sugalsd@stargate.lbcc.cc.or.us>
If ORACLE_HOME isn't set, Oracle.pm no longer tries to guess it.
bind_param_inout now checks for read-only variables.
Requires DBI 0.84.
=head1 Changes in DBD::Oracle 0.45 (Oraperl 1.33), 16th June 1997
A $dbh DESTROY without an explicit disconnect does a rollback.
Note that this may 'break' existing 'lazy' code but is completely
essential for robust applications. See comments in Oracle.xs.
Added Makefile.PL changes from Eric Bartley and others.
The changes should fix build problems for Oracle 7.3.x.
Requires DBI 0.83.
Oraperl now uses DBI->connect and thus works with DBI 0.81 to
automatically support Apache without requiring script changes.
Reworked parameter binding in preparation for future changes.
- mutated placeholder values are now automatically rebound.
- in/out vars that become undef/null after binding now work.
- transparent support for longs should be easier to implement.
Added Win32 support from Jeff Urlwin.
Added some documentation to DBD::Oracle for 'perldoc DBD::Oracle'.
Most tests now converted to standard t/*.t format.
Added $sth->{NULLABLE}->[$field].
Added private plsql_errstr method: $txt=$dbh->func('plsql_errstr')
to fetch PL/SQL error messages. Thanks to Bob Menteer.
Added $sth->{ora_pad_empty} and ORAPERL_PAD_EMPTY env var
for better compatibility with old oraperl.
Added $sth->{AutoCommit} FETCH.
Added $sth->{ChopBlanks} (but not yet tested).
No longer asks Oracle for text of login failure message since
that can cause oracle's code to hang (sigh). We provide fake text
for the most common errors and a useful default for the rest.
You can set DBD_ORACLE_LOGIN_ERR env var to revert to old behaviour.
The Copyright terms for DBD::Oracle have changed and now read as follows:

License or the Artistic License, as specified in the Perl README file,

=head1 Changes in DBD::Oracle 0.44 (Oraperl 1.30), 14th Jan 1997
Fixed leak in read_blob (thanks to Jurgen Botz for the patch).
Improved automatic cache sizing (so better default caching).
Negative cache size specifies desired cache/transfer size in bytes.
Added $rowid = $csr->{ora_rowid} attribute (untested, please test).
(Use via $csr->bind_param(1, $rowid, { ora_type => 11 });)
Queries returning LONG's are no longer cached (so there's no
need to set the cache to 1 explicitly to get read_blob to work).
Added a test using string type with bind_param_inout in test.pl.
Worked around the rather sad VMS linker case insensitivity.
Worked around VMS linker length warning on XS...disconnect_all.
Makefile.PL deletes non-existant files from $(COMPOBJS)
(thanks to aburlison@cix.compulink.co.uk for the original patch)
=head1 Changes in DBD::Oracle 0.43 (Oraperl 1.30), 29nd Oct 1996
Fixed serious 'false ora_errno 1 after short select' bug.
Worked around oracle bug that makes cda->ft unreliable.
Do not use DBD::Oracle 0.41 or 0.42.
Cursors are now 'describe'd at prepare time thus making
NUM_OF_FIELDS always available. Describe does nothing for
non-select operations. NUM_OF_FIELDS > 0 is now used to
select between oexec() and oexfet() in execute().
Added more internal debugging. Improved test.pl.
=head1 Changes in DBD::Oracle 0.42 (Oraperl 1.30), 28nd Oct 1996
Fixed serious 'cache empty after re-bind' bug.
Do not use DBD::Oracle 0.41.
Implemented oexfet (combined execute and cache fetch) for
select operations. This is a further significant speed up.
Many selects now make only one trip to Oracle (after prepare)
which combines the execute and fetching multiple rows.
=head1 Changes in DBD::Oracle 0.41 (Oraperl 1.30), 22nd Oct 1996
Added the long overdue row cache to DBD::Oracle.
(Thanks to Reetnem@aol.com for providing a patch that prompted
me to complete the work.)
Oraperl $ora_cache and cache parameter to ora_open now work.
Default cache size is adjusted automatically for row width.
Major reworking of field buffer memory management.
Added a more internal debugging.
Further updates to the README files.
=head1 Changes in DBD::Oracle 0.40 (Oraperl 1.29), 14th Oct 1996
WARNING - This release contains significant changes to the
placeholding binding code. You should test it carefully
before using in live systems.
Implemented PL/SQL output values via $sth->bind_param_inout.
See the code at the end of test.pl for example usage.
Binding is now implemented using obndra rather than obndrv.
This may have a subtle effect when matching char fields
against placeholders with trailing spaces.
Fixed bind_param ora_type attribute. Thanks to Stephen Zander
for the patch. Updated README's. Added README.longs.
=head1 Changes in DBD::Oracle 0.39 (Oraperl 1.29), 23rd Sep 1996
Fix for DEC "target := MACRO = string" Makefile syntax.
Added README notes from Dave Moellenhoff, Lou Henefeld and others.
Added README.login from James Taylor.
Added README.client with various notes about building DBD::Oracle
on minimaly configured client systems.
Extra parameters to ora_do are now passed to DBI's do().
(This is an extension to the original oraperl ora_do.)
=head1 Changes in DBD::Oracle 0.38 (Oraperl 1.28), 22th Aug 1996
Overhaul of Makefile variable parsing. Should now cope with
complex variables which expand to nested shell escapes.
Try perl Makefile.PL -v to watch the fun.
Updated README, Makefile.PL and test.pl messages for clarity.
Fixed possible memory corruption in dbd_bind_ph().
=head1 Changes in DBD::Oracle 0.37 (Oraperl 1.28), 25th July 1996
Fixed Makefile.PL for Oracle 7.3.2.
Fixed $num_fields = ora_fetch($csr) before first fetch for
queries with bind vars.
Fixed occasional core dump on global destruct.
=head1 Changes in DBD::Oracle 0.36 (Oraperl 1.28), 10th July 1996
Fixed bind_param ora_type attribute.
Fixed preparse to allocate enough memory for worst case.
Fixed broken HP-UX 10 check in Makefile.PL.
Other assorted Makefile.PL improvements.
(Many thanks to those who sent in fixes.)
=head1 Changes in DBD::Oracle 0.35 (Oraperl 1.28), 21st June 1996
Fixed broken Solaris 2.5 check in Makefile.PL.
Added ld path to the log.
=head1 Changes in DBD::Oracle 0.34 (Oraperl 1.28), 21st June 1996
Workaround Solaris 2 bug #1224467 (_rmutex_unlock).
With many thanks to James Taylor.
Added 'Bad free()' warning suppression to ora_logon and
ora_logoff(). Setting the DBD_DUMP environment variable
will trigger a (handy for me) core dump if a Bad free
warning is detected.
Further additions to the README about Bad free()'s.
=head1 Changes in DBD::Oracle 0.33 (Oraperl 1.27), 19th June 1996
Added Makefile.PL -g option to enable debugging.
Added Makefile.PL -s symbol_name option to search for symbols.
Reorganised the way Makefile.PL uses MakeMaker liblist code.
Oraperl defaults to the 'safe' (normal) mode of using the DBI.
Oraperl uses sigtrap on SEGV & BUS to give a perl stack trace.
Added README notes about -g option, core files and stack traces.
Small change to $dbname/$user/$passwd logic in connect.
=head1 Changes in DBD::Oracle 0.32 (Oraperl 1.25), 30th May 1996
Fixed memory leak when FETCH'ing attributes.
Fixed Makefile.PL FileHandle problem (forgot 'use FileHandle;').
Enhanced Makefile.PL support for Oracle 7.3.
=head1 Changes in DBD::Oracle 0.31 (Oraperl 1.25), 20th May 1996
Makefile.PL for HP-UX now defaults to dynamic for hpux >= 10.
execute (ora_bind/ora_do) now returns undef on error or the
number of rows affected (0 is returned as 0E0, hence true, for
okay but no rows affected or no row count available/applicable).
This matches the oraperl version 2.4 behaviour.
Made an attempt at supporting Oracle 7.3 (e.g. include's in proc.mk)
Please let me know if it works (else supply patches to fix it :-)
Fixed small memory leak in ora_titles etc functions.
=head1 Changes in DBD::Oracle 0.30, 7th May 1996
THE ORAPERL EMULATION LAYER IS NOW FORMALLY RELEASED (NO LONGER ALPHA).
Note that the underlying DBI and DBD::Oracle interfaces remain alpha
because they are still subject to (possibly significant) change.
Oraperl v2 used to return the string 'OK' to indicate success
with a zero numeric value. The Oraperl emulation now uses the
string '0E0' to achieve the same effect since it does not cause
any -w warnings when used in a numeric context.
Fixed typecast warning (s/safefree/Safefree).
Automatically sets/resets ORACLE_HOME from oratab value for sid.
TO DO: Automatic configuration from Oracle 7.3 is not yet working
(Oracle have reorganised the makefiles yet again!).
=head1 Changes in DBD::Oracle 0.29, 2 March 1996
Fixed Makefile.PL to get DBIXS.h from right spot.
Changes to suit perl5.002 and site_lib directories.
Detects old versions ahead of new in @INC.
Random tidy-ups.
=head1 Changes in DBD::Oracle 0.28, 29 Jan 1996:
Minor release for Perl5.002 (beta2 or later).
Requires Perl5.002 and DBI 0.66;
Only functional change is to suppress (rare) 'handle not setup'
warnings unless debugging.
=head1 Changes in DBD::Oracle 0.27, 16 Nov 1995:
Improved oraperl compatibility in assorted ways.
Added the original oraperl manual to Oraperl.pm as pod.
(perldoc Oraperl will display the manual).
The manual highlights remaining differences in the emulation.
Added original oraperl examples into oraperl.ex directory.
Improved error reporting in test.pl.
Removed some internal limits.
Renamed readblob to blob_read and fixed return value.
Implemented $sth = $dbh->tables method (see DBI changes file).
Uses $Config{archlibexp} not $Config{archlib} in makefile.PL
Requires DBI-0.65.
I've still not got around to implementing a row cache (array
fetch) but it's next on my list.
This should be the last alpha release of the oraperl emulation.
(The DBD::Oracle module itself will remain alpha for awhile yet.)
=head1 Changes in DBD::Oracle 0.26, 23 Oct 1995:
Removed error message (sql) size limits in parse and ora_error.
Fixed FETCH NUM_OF_PARAMS so it doesn't trigger a describe.
The ora_lengths and ora_types attributes work in non-oraperl mode.
=head1 Changes in DBD::Oracle 0.25, 26 Aug 1995:
User visible changes:
Fixed bug in parsing '?' style placeholders.
$sth->bind_param now checks for a too long LONG type string.
$sth->prepare now takes attributes:
ora_parse_lang => 0 | 1 | 2 (v6, auto v6/v7, v7)
ora_parse_defer => 0 | 1 (control defered parsing)
Other changes to be propogated to other drivers:
Added usage of new DBD_ATTRIB_* macros to XS and C code.
dbd_bind_ph return value inverted to make it consistent.
Added braces around XSRETURN_UNDEF in execute.
Checked for describe failure in FETCH.
Removed NumParams since it's now called NUM_OF_PARAMS in DBI.
Updated NEED_DBIXS_VERSION in Oracle.h
=head1 Changes in DBD::Oracle 0.24, 22 Aug 1995:
User visible changes:
$sth->bind_param method implemented (needs testing :-)
and new DBI $sth->bind_col* methods work for DBD::Oracle.
Other changes to be propogated to other drivers:
- Slight change to STORE functions to allow them to return status
if called as $h->STORE(...).
- Revised signature of dbd_bind_ph function and added a bind_param
method for it. Prototype moved from dbdimp.h to Oracle.h
- Revised execute method to use modified dbd_bind_ph function and
remove remaining oracle specifics.
- imp_xxh_t structures first element now called 'com' not 'dbihcom'
and new DBI macros used to access fields.
=head1 Changes in DBD::Oracle 0.23, 18 Aug 1995:
Fixed Oraperl.pm debug which was left on by default by accident.
Added small patches from Davide.Migliavacca@inferentia.it for
longs (dbtype_is_long, dbd_describe and dbd_st_readblob).
Added svr4 hints from Alan Burlison <aburlison@cix.compulink.co.uk>
Changed dbd_describe to return true for success (to be consistent).
=head1 Changes in DBD::Oracle 0.22, 17 Aug 1995:
Much more maturity, in line with the required DBI-0.60 release.
The .xs file is now very 'clean'. It's an excellent base for
developing other drivers. See notes in the DBI Changes file.
The oraperl &ora_do should be working now (along with $sth->do()).
It does not leak (as far as I can tell).
This release is stable enough for general use again (like 0.20).
Please test heavily.
=head1 Changes in DBD::Oracle 0.21, 15 Aug 1995:
NOTE: THIS IS AN UNSTABLE RELEASE!
It requires the closely related DBI 0.59 release.
See Changes file in that release.
Major reworking of internal data management!
Only execute and fetchrow have yet to move into dbdimp.c.
These were kept back since I plan other associated changes.
Known problems:
Warning mode is on by default so certain oraperl coding
styles cause warnings such as:

In future oraperl mode handles will have those warnings disabled.
...other changes to numerous/minor to mention
=head1 Changes in DBD::Oracle 0.20, 1 Aug 1995:
Fixed core dump when binding an undef (treated as a NULL)
Binding a string longer that 2000 bytes will use LONG type.
Workaround OSF makefile and oratype.h problems
PL/SQL := construct will no longer confuse dbd_preparse()
=head1 Changes in DBD::Oracle 0.19, 21 June 1995:
Added $VERSION
disconnect_all now gives error 'not implemented'.
Reworked memory management, imp_dbh's are cached.
imp_dbh_t now has an in_use flag and generation counter.
st::DESTROY now checks its imp_dbh for validity.
&ora_do() now returns "OK" for 0 rows (as per oraperl).
Reworked logging to use DBILOGFP macro.
Now test code added to loop through logon/prep/fin/logoff.
=head1 Changes in DBD::Oracle 0.18, 17th June 1995
Makefile.PL: HPUX now builds with LINKTYPE=static automatically.
Fixed errors on logout/global destruction.
Added logout/global destruction test to test.pl.
Changed Oraperl.pm default mode from safe to fast (see func_ref()).
Added platform who's-who list to README.
Added $sth->readblob($field, $offset, $length [, \$dest) method.
(You need to add the following after line 80 in DBI/DBI.pm:
'readblob' => {'U'=>[4,5,'$field, $offset, $len [, \\$buf]']},
in order to access the new readblob method.)
=head1 Changes in DBD::Oracle 0.17, 9th June 1995
Further enhancements to proc.mk parsing (this should fix
the bug introduced in the last version which required the
manual editing of -lora etc into the link line).
Automatic use of proc16.mk if proc.mk not found.
Automatic use of -Xa if compiler is 'clcc' (CenterLine).
Further migration of code from Oracle.xs to dbdimp.c. This is
not complete but may give you a flavor of my current direction.
Fixed more warnings from pedantic compilers.
[Released with DBI 0.56]
=head1 Changes in DBD::Oracle 0.16, 25 May 1995
Makefile.PL more robust and flexible.
Code restructured - much more still to do.
Changes to ora_do. It's probably still not right.
[Released with DBI 0.55]
=head1 Changes in DBD::Oracle 0.15, 25 Apr 1995
Fixed all known build problems/core dumps/truncated data etc.
Returns undef for NULLS.
Bind vars still not supported (soon I hope).
Bind vars produce errors rather than being ignored.
Login usage of ORACLE_SID and TWO_TASK slightly revised.
test.pl now uses ORACLE_SID, TWO_TASK and ORACLE_USER if defined.
=head1 Changes in DBD::Oracle 0.14, 5 Apr 1995
Fixed assorted build and core-dump problems.
=head1 Changes in DBD::Oracle 0.13, 8th March 1995
"Another alpha release but hey, guess what, this one actually allows
you to fetch data :-)"
=head1 Changes in DBD::Oracle 0.12, 1st March 1995
"For DBD::Oracle I have implemented a fairly radical way to deal with
the nightmare of Oracle OCI makefiles. Rather than try to maintain a
*large* and complicated set of Makefile macros the DBD::Oracle
Makefile.PL now actually extracts the macros which oracle itself uses
from $ORACLE_HOME/rdbms/lib/oracle.mk! (The horses mouth, so to speak.)"
[Released with DBI 0.53]
=head1 Changes in DBD::Oracle 0.11, 24th Feb 1995
"The first fruits of that work are now available for the brave (or
foolhardy). Take note: this very much *unsupported* *alpha* software
(it does not even fetch records from oracle yet). Feel free to ftp it
but don't expect to do anything very useful with it."
Also first release of the Oraperl emulation module:
"Yes, that's real oraperl code and it works! The only addition is
the 'use DBD::Oraperl' line."
[Released with DBI 0.51]
