- alias_value: The alias or connect identifier that is used.
- repository_loc: The naming method repository or the repository that cannot be located or reached.
Cause
A connection to a database or other service is being requested using a connection alias but the alias specified cannot be resolved into a connect descriptor using one of the configured naming methods.
Action
Do the following:
- Check for mistakes in the connection string that you used.
- If you have a sqlnet.ora file containing a NAMES.DIRECTORY_PATH parameter, then ensure that the parameter contains valid values.
- If you are using an alias from a tnsnames.ora file:
- Verify that the tnsnames.ora file exists, is in the proper directory, and is accessible.
- Ensure that the alias exists in one of the tnsnames.ora files.
- Ensure that there are no syntax errors anywhere in the tnsnames.ora file or files. Look for unmatched parentheses or stray characters. Ensure that magic quotes are not used.
- If you are using LDAP directory naming:
- Verify that the net service name or database name used as the connect identifier is configured in the directory.
- Verify that the LDAP directory server is up and that it is accessible.
- Verify that the default context being used is correct by specifying a fully qualified net service name or a full LDAP DN as the connect identifier.
- If the error is for a dblink connection, check all of the above for Database Server process making connection to remote database.
