Modifying Oracle Clusterware Binaries After Installation
After installation, if you need to modify the Oracle Clusterware configuration, then you must unlock the Grid home. Review this information about unlocking the Grid home.
For example, if you want to apply a one-off patch, or if you want to modify an
Oracle Exadata configuration to run IPC traffic over RDS on the interconnect instead of
using the default UDP, then you must unlock the Grid
home.
Caution:
Before relinking executables, you must shut down all executables that run in the Oracle home directory that you are relinking. In addition, shut down applications linked with Oracle shared libraries.
