SAP Host Agent – update

Today will be a few words about how to update SAP Host Agent (I’ll be use shortcut: SHA). I’ll start with that SAP Host Agent is an agent that can accomplish several life-cycle management tasks, such as operating system monitoring, database monitoring, system instance control and provisioning, etc. Latest documentation to SHA You can find in this note.

Check current SHA version

->#/usr/sap/hostctrl/exe/saphostexec -version

Update SHA

First we need download the latest SAP Host Agent from the SAP Software Download Center

In the navigation bar, choose:
 -> SAP Software Download Center
 -> Support Packages and Patches
 -> Browse our Download Catalog
 -> SAP Technology Components
 -> SAP HOST AGENT
 -> SAP HOST AGENT 7.22
 -> <your operating system>

In this case I’ll be download the newest version at the moment, file: “SAPHOSTAGENT54_54-80004822.SAR“.

Next, follow the procedure below:

-- I downloaded file to directory: /mnt/nfs/SAPHostAgent/SAPHOSTAGENT54
-># ls
SAPHOSTAGENT54_54-80004822.SAR

-- In this directory, extract the SAPHOSTAGENT SAR file
-># [PATH_TO_SAPCAR]/SAPCAR -xvf SAPHOSTAGENT54_54-80004822.SAR
