SAP SID size

[Former Member]

How big (how many characters) can a SAP SID or appserver name can be? Also, how big can a SAP hostname can be?

Thank you,

Hi,

all necessary information could be found in the Installation Guide.

The SAP System ID <SAPSID> identifies the whole SAP
system.
Caution
Choose your SAP system ID carefully. You cannot change
the SAP system ID after the installation.
Make sure that your SAP system ID:
- Is unique throughout your organization
- Consists of exactly three alphanumeric characters
- Contains only uppercase letters
- Has a letter for the first character
- Does not include any of the following, which are reserved
IDs:
ADD ALL AND ANY ASC AUX COM CON DBA END EPS FOR
GID IBM INT KEY LOG LPT MON NIX NOT NUL OFF OMS
PRN RAW ROW SAP SET SGA SHG SID SQL SYS TMP UID
USR VAR
