SAP System ID <SAPSID>

See Note 1979280 for the reserved SIDs

Instance Number

The technical identifier for internal processes It is a 2 – digit number from 00 to 97 (do not use 02 or 75) It must be unique on the host

Virtual Host Name

Individual Encryption Key for Secure Storage

You can set a randomly generated individual encryption key for the secure storage in the file system and the secure storage in the database.

DNS Domain Name for SAP System

The DNS Domain Name is used to calculate the Fully Qualified Domain Name which is configured in SAPLOCALHOSTFULL. It consists of the hostname and the domain name.

ABAP Message Server Port

If you do not specify a value, the default value will be used. (This is what you want) The ports must be unique on all hosts. The default external message server port is 36<ABAP_MESSAGE_SERVER_INSTANCE_NUMBER>. The default internal message server port is 39<ABAP_MESSAGE_SERVER_INSTANCE_NUMBER>.
