|ORA-01498:||block check failure - see trace file|
|Cause:||An error occurred while checking a block with the ANALYZE command.|
|Action:||Check the trace file for more descriptive messages about the problem. Correct these errors. The name of the trace file is operating system-specific, for example, ORAxxxx.TRC. It is found in the directory specified by the initialization parameter USER_DUMP_DEST. If USER_DUMP_DEST is not set, trace files are not created. It may be necessary to re-create the object. See also your operating system-specific Oracle documentation.
