Cause: One of the following events caused an incompatibility: 1) Parameter LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST was in use when the specified LOG_ARCHIVE_DEST_n (n = 1...31) or DB_RECOVERY_FILE_DEST parameter was encountered while fetching initialization parameters. 2) Parameter LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST was in use when an attempt was made to use an ALTER SYSTEM or ALTER SESSION command to define a value for the specified LOG_ARCHIVE_DEST_n or DB_RECOVERY_FILE_DEST parameter. 3) An ALTER SYSTEM ARCHIVE LOG START TO command was in effect when the specified LOG_ARCHIVE_DEST_n parameter was encountered while fetching initialization parameters. 4) An ALTER SYSTEM ARCHIVE LOG START TO command was in effect when an attempt was made to use an ALTER SYSTEM or ALTER SESSION command to define a value for the specified LOG_ARCHIVE_DEST_n parameter. See the solution below.

Error solution: Eliminate any incompatible parameter definitions.
