[opencms-dev] OpenCms + Oracle working together!

[mfoley5 at csc.com.au]

Hi All,

Having beaten my head against non-OpenCms issues with WebLogic and the
Oracle Oci driver for too long I have re-visited the GenericSql option
using the 'thin' driver, and think I have a solution.

It appears the "date/time" issue reported earlier is related to the size of
the byte array passed to the *.setBytes() calls in
com.opencms.file.genericSql.CmsDbAccess.  I gather that the Oracle driver
has a limit of 2000 bytes here and this produces the (misleading) error.

I have replaced setBytes with setBinaryStream and have written a new class
which simply turns the byte array into an Object extending
java.io.InputStream.

I've run through about 5 test cases where the original genericsql fell over
and so far no problem.  Testing continues on WebLogic/Solaris, and I will
be running this later on WebLogic/Win2000 just to make sure.     So far I
have only modified CmsDbAccess, but I suspect it may be necessary to modify
CmsCallableStatement and CmsPreparedStatement as well.

If this is a truly useful change/finding, then I would like comments from
the OpenCms Group, please.       Also, if I have missed something Really
Important, then I'd like to hear that too.

Regards,
Mark
