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. ================ Revision History ---------------- 06-FEB-2001: added ldconfig warning to README 08-FEB-2001: added libnsl.so stub needed for OPS cm/nm 28-FEB-2001: move stub libraries from $OH/lib to $OH/lib/stubs 01-MAR-2001: added stubs for all remaining glibc libraries 14-MAR-2001: added setup_stubs.sh to simplify installation 16-MAR-2001: added patch description and notes for application developers |
