Oracle Error Message
ORA-16018: cannot use string with LOG_ARCHIVE_DEST_n or DB_RECOVERY_FILE_DEST
Reason for the Error
One of the following events caused an incompatibility: 1) Parameter LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST was in use when a LOG_ARCHIVE_DEST_n (n = 1…31) parameter was encountered while fetching initialization parameters. 2) An ALTER SYSTEM ARCHIVE LOG START TO command was in effect when a LOG_ARCHIVE_DEST_n parameter was encountered while fetching initialization parameters. 3) A LOG_ARCHIVE_DEST_n parameter was in use when an ALTER SYSTEM command was used to define a value for either the LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST parameter. 4) Parameter DB_RECOVERY_FILE_DEST was in use when an attempt was made to use an ALTER SYSTEM or ALTER SESSION command to define a value for LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST.
Solution
Eliminate any incompatible parameter definitions.
