• EVENT:10212 check cluster integrity


    Error:  ORA 10212
    Text:   check cluster integrity
    -------------------------------------------------------------------------------
    Explanation:
            This is NOT an error but is a special EVENT code.
            It should *NOT* be used unless explicitly requested by RD support.
    
            Event 10212 enables cluster block integrity checking.
            The causes a number of checks on the contents of a block.
            If the block is found to be corrupt in some way it is marked as
            SOFTWARE CORRUPT.
    
            NB: Blocks are ONLY checked/corrupted when CHANGED. They are NOT checked
                when accessed for read.
    
            Take care with this as if there are blocks in the database which
            are being accessed happily but have a minor corruption this will
            mark the block as corrupt.
    
            Once a block in an cluster is marked SOFTWARE CORRUPT it is best to
            rebuild the entire cluster.
    
    Usage:  event="10212 trace name context forever, level 10"
