（1）In 10g and 11.1, Oracle Clusterware binaries cannot be relinked. However, the client shared libraries on that home can be relinked, in most cases there should not be a need to relink them. See Note:743649.1 on how to do that.
      clntsh.map
      clntst_1.lis
      clntst_2.lis
      clntst.lis
       libclntsh.so
       libclntsh.so.10.1
       libclntst10.so
       libclntsh.so.11.1
       libclntst11.so

       libclntst11.a

      Keep a note of their original settings so that you can change them back later.

（2）Relink the Oracle Clusterware client-shared libraries as the Clusterware owner:

    $ cd <CRS-HOME>/bin
    $ ./genclntsh

In 11.2, there are some executables in the Grid home that can and should be re-linked after an OS upgrade. The procedure to do this is:

引用

# cd Grid_home/crs/install
# perl rootcrs.pl -unlock

As the grid infrastructure for a cluster owner:

$ export ORACLE_HOME=Grid_home
$ Grid_home/bin/relink

As root again:

# cd Grid_home/crs/install
# perl rootcrs.pl -patch
