Supported Document Formats, 2 of 4
Oracle Text uses document filtering technology licensed from Inso Chicago Corporation. This filtering technology enables you to index most document formats. This technology also enables you to convert documents to HTML for document presentation, with the CTX_DOC package.
To use Inso filtering for indexing and DML processing, you must specify the INSO_FILTER object in your filter preference.
To use Inso filtering technology for converting documents to HTML with the CTX_DOC package, you need not use the INSO_FILTER indexing preference, but you must still set up your environment to use INSO filtering technology as described in this appendix.
To convert documents to HTML format, Inso filtering technology relies on shared libraries and data files licensed from Inso Corporation and Adobe Corporation.
The following sections discuss the supported platforms and how to enable Inso filtering on the different platforms.
Inso filter technology is supported on the following platforms:
All environment variables related to Inso filtering must made visible to Oracle Text. Set these variables in the following location:
ctxsrv
server is started. This makes the environment variables visible to the ctxsrv
process, which does background DML.
The following requirements apply to Solaris, IBM AIX, HP/UX, Digital UNIX, SGI, and Linux platforms:
$PATH
variable to include the location of the *.flt files, in particular to the location of the file isunx2.flt
, and to $ORACLE_HOME/ctx/lib which is the location of the shared libraries for Inso filtering
$HOME
environment variable to allow Inso technology to write files to a sub-directory (.inso) in $HOME
directory.
Set the system's shared library path ($LD_LIBRARY_PATH
) environment variable to include $ORACLE_HOME/ctx/lib.
Set the system's shared library path ($LIBPATH
) environment variable to include $ORACLE_HOME/ctx/lib.
You must include /usr/lib:/lib
in $LIBPATH
, because these directories are not searched by default once $LIBPATH
environment variable is set.
Set the system's shared library path ($SHLIB_PATH
) environment variable to include $ORACLE_HOME/ctx/lib.
Set the system's shared library path ($LD_LIBRARY_PATH
) environment variable to include $ORACLE_HOME/ctx/lib.
Follow these steps to filter vector graphic formats on UNIX platforms:
$DISPLAY
environment variable. For example, setting DISPLAY=:0.0
tells the system to use the X server on the console.
There are platform dependent limits on what Inso filter technology can do with OLE2 objects. On all platforms when a metafile snapshot is available, Inso technology will use it to convert the object.
When a metafile snapshot is not available on UNIX platforms, Inso technology cannot convert the OLE2 object.
However, when a metafile snapshot is not available on the NT platform, the original application is used (if available) to convert the OLE2 object.
