When we create the database with the same name we are creating he below error.
Error: The database SID you have specified,orcl, is Already present on this Host. Please specify a SID that is unique on this Host
![]()
Cause:
You have probably previously created database with the same name and have removed it but the traces of it still remain
Solution:
Open /etc/oratab file in edit mode and remove the line containing SID that is causing an error message.
Another place to look would be $ORACLE_BASE/oraInventory/ContentsXML/inventory.xml - this file could also contain an entry with the offending SID
