: otn.oracle.com 에 있는 자료와 내용입니다.. : : 자료: http://download.oracle.com/otn/linux/oracle8i/glibc-2.1.3-stubs.tar.gz : : ================= : 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
