March 20th, 2009
Description:
ORA-12315 database link type is invalid for the ALTER DATABASE statement
Cause:
The database link name you specified on the ALTER DATABASE statement is not an ROM: link. You must specify an ROM: link when using the ALTER DATABASE statement to mount or open a secondary database.
Re-issue the
ALTER DATABASEstatement using a valid ROM: link to the database you want to mount or open. If a valid ROM: link does not exist, create one using theCREATE DATABASE LINKstatement. See your documentation for Oracle security-related products for more information about creating database links using the ROM: link type.
