Installing and Updating Software on
Linux 
You choose a SAP DB software component, and install it.
Use
the following procedure for updates only if no
database instances
refer to the installation path of the software that you want to
update.

If database instances refer to the installation path of the software, you must update the database instances together with the software (Updating Database Instances and Their Software). Otherwise, you risk making the database instances incompatible with the database software, and you will not be able to run them.
Two programs are available for installations on Linux:
· Installations/Updates with the Red Hat Package Manager
· Installations/Updates with SDBINST
