In sap system, a patch is used to fix a bug. SAP patching is the process of updating your current SAP system to the latest or newer patch level.
The SAP HANA appliance is shipped with the latest available support package stack and the customer is usually responsible for implementing any subsequent updates and patches.
The SAP hardware partners ships the SAP HANA appliance pre-configured with the most recent support package stack that is available. The customer is responsible for the subsequent implementation of SAP HANA patches, revisions, or support packages and support package stacks.
In general the following points apply:
- Any system connected to the SAP HANA system, as a source or as a client, may require a minimum SAP HANA support package stack to be implemented. Unless explicitly stated, we recommend applying the latest SAP HANA support package stack after applying an update to the connected system.
- The SAP HANA support packages are cumulative. You can update directly from any older SAP HANA support package to any newer SAP HANA support package.
- New SAP HANA support packages mainly cover software improvements. SAP recommends that you download and install these new SAP HANA support packages if SAP support has to resolve issues with SAP HANA versions previously installed in your landscape. However, customers do not necessarily need to update their SAP HANA landscape with the newest SAP HANA support packages if their SAP HANA landscape works correctly.
- New SAP HANA support packages and patches will be produced and shipped at SAP’s sole discretion. There is no periodic cycle for releasing and patching the SAP HANA software. The new SAP HANA support package stacks will be communicated to customers and hardware partners by means of SAP Notes.
. It is strongly recommended after the initial setup and before every system update, that you perform a full data and file system backup (including a configuration backup).
. Special support agreements may exist with the hardware partner which include services such as patching.
