can be the same as the <SAPSID>.
Choose your database ID carefully. Renaming is difficult and requires that you reinstall the SAP system.
Database schema, Passwords
The Java database schema is named SAP<SCHEMA_ID>DB. Default name is SAPSR3DB.
Choose a <SCHEMAID>that is different from your <SAPSID>.It might cause problems when you copy a system where <SCHEMAID>is the same as <SAPSID>, and the database-specific method used for the copy does not allow you to rename the database schemas. In certain situations, you might create a system copy with a new <SAPSID>, but where the database schema has the old <SAPSID>. This is not a technical problem, but might confuse the system administrator</note>
Diagnostics Agent Parameters
The diagnostics agent is installed automatically with the SAP system.
DASID
The System ID of the Diagnostics Agent (DASID)SAPinst sets the system ID of the diagnostics agent, <DASID>, to DAA by default.If DAA is already used, SAPinst assigns another default system ID. You can overwrite the default system ID as required.<DASID>must follow the same restriction than the sapsid.
Installation
Do not install the Oracle database software before you run SAPinst.SAPinst stops and prompts you to install the Oracle database [page 85] while the installation of the database instance is running.
After Installation
Missing table entries in the database
After you install an SAP system under Linux, a few entries are missing in the tables TSLE2 and TSLE3. The procedure described in Note sap/support/notes/836992 corrects this.
