: =================
: Patch Description
: -----------------
: Oracle8i for Linux is shipped with archived objects which were compiled using
: glibc-2.1.3. The executable components are then linked at install-time using
: these archives. Due to compatibility limitations in glibc, if the target
: system for an installation is based on a later version of glibc, then the
: executables produced by the linker will not be valid. As a workaround to
: this limitation, we have created a set of stub libraries which are used at
: link-time only to mimic the contents of glibc-2.1.3 shared objects. Note
: that these stub libraries do not contain valid executable code, and therefore
: *must NOT* be included in the library path searched by the dynamic loader
: (i.e., do not include $ORACLE_HOME/lib/stubs in LD_LIBRARY_PATH).
:
: ===========================================
: Instructions for New Oracle8i Installations
: -------------------------------------------
:
: Install Oracle8i as usual, but choose not to create a database during install.
:
: Once installation is complete, follow the procedure described in the
: section "Instructions for Existing Installations" below. It will then
: be possible to create a database.

: ================================================
: Instructions for Existing Oracle8i Installations
: ------------------------------------------------
:
: Place the tar file glibc-2.1.3-stubs.tar.gz in $ORACLE_HOME. Make sure
: ORACLE_HOME is set in your environment. Then carry out the following steps:
:
: cd $ORACLE_HOME
: tar xvfz glibc-2.1.3-stubs.tar.gz
: ./setup_stubs.sh
:
: You should now be able to use Oracle as usual.
:
: ================
: Warning
: ----------------
:
: Make sure the directory $ORACLE_HOME/lib is not listed in your
: /etc/ld.so.conf. The system could potentially become unstable after applying
: this patch in that case. If $ORACLE_HOME/lib is currently listed in
: /etc/ld.so.conf, remove it and run ldconfig before applying this patch.

: Notes for Application Developers
: --------------------------------
:
: If your application does not require linking at install sites, then no
: additional steps are required for your application to be compatible with
: glibc or the Oracle8i client shared library after the installation of this
: patch. This is true regardless of whether your application was compiled
: using glibc-2.1.3 or a later version.
:
: If your application is compiled using glibc-2.1.3 and requires linking at
: install-time using the Oracle8i client shared library, then you may also
: need to link your application using the stub libraries provided in this
: patch. For example, an application which might typically be linked as
: follows on a glibc-2.1.3 based system:
:
: gcc -o app app.o -L$ORACLE_HOME/lib -lclntsh
:
: should now be linked as follows on systems with a newer version of glibc,
: in order to ensure compatibility:
:
: gcc -o app app.o -L$ORACLE_HOME/lib -L$ORACLE_HOME/lib/stubs -lclntsh
:
: If your application is compiled using a version of glibc later than 2.1.3
: and requires linking at install-time using the Oracle8i client shared
: library, then you must NOT link your application with the stub libraries
: provided in this patch. Doing so may either cause the link to fail or the
: resulting executables to be invalid.
:
: Note that the stub libraries provided in this patch only cover the shared
: objects that make up glibc. If your application must be linked at install-
: time with other shared objects which were built to have dependencies on the
: locally installed version of glibc (e.g., X11), then your application must
: be compiled using the same version of glibc that was used by those other
: components. For example, on a system with glibc-2.2, linking your
: application with libX11.so will fail if you attempt to use the glibc-2.1.3
: stub libraries, since libX11.so on that system will have been compiled and
: linked using glibc-2.2.
