In this document, the term “update” is used as a collective term for all the software logistics processes that you can perform using the Software Update Manager (such as performing release upgrades, installing enhancement packages, or updating a system with support package stacks).

The Software Update Manager evolved from the previous SAP Enhancement Package Installer and SAP upgrade tools. The tool has been renamed to reflect its broader use.

However, note that on a technical level, the name of the executable SAPup is still in use, for example, in the log files or in commands.

In this document, “SUM directory” and “<update directory>” are used as synonyms when referring to directory <path to SUM directory>/SUM.

In this document, the term “SAP system” is used for SAP NetWeaver systems as well as for SAP application systems. “SAP” is also used as a synonym for “SAP NetWeaver” or “SAP application” in terms such as “SAP start profile” or “SAP system language”.

In this document, the SAP system ID is abbreviated as “SAPSID” or “sapsid”. If “<sapsid>” is used, your SAP system ID has to be in lowercase letters, for example, “prd”. If “<SAPSID>” is used, you have to write in uppercase letters, for example, “PRD”.

In this document, “<rel>” stands for the relevant SAP system release, without a decimal point, such as “740”. If an enhancement package has been installed in the system, the last digit indicates the enhancement package version, such as “731” for SAP enhancement package 1 for NetWeaver 7.3.

As of SAP NetWeaver 7.1, the concept and naming of SAP system instances has changed. The terms “central instance” and “dialog instance” are no longer used. Instead, the SAP system consists of the following instances:

• Application server instances

  Application server instances can be installed as “primary application server instance” or “additional application server instances”.

• Central services instance

• Database instance

Throughout this document, we use the new terms “primary application server instance” and “additional application server instance”. For releases lower than SAP NetWeaver 7.1, the “primary application server instance” corresponds to the “central instance” and the “additional application server instance” corresponds to the “dialog instance”.

As of operating system version 10, Solaris has been renamed to “Oracle Solaris”. However, the former name “Solaris” may occur in this document as well.
