What is the maximum length an Oracle SID can be? I've read some documentation stating it can be between 8 and 16 characters, depending on version, but also some documentation warns of errors if trying to create a SID of greater than 8 characters. Is there is definitive answer to this please?



and we said...

From the 12.2 documentation:

"It is common practice to set the SID to be equal to the database name. The maximum number of characters for the database name is eight. For more information, see the discussion of the DB_NAME initialization parameter in Oracle Database Reference."

So even if you find a platform that does more than 8, I would never go more than that.
