Answer / guest
Cause: In the XDB$H_INDEX table, the CHILDREN column, a
BLOB, must have a certain minimum length without being
chained. The calculated length of the LOB was less than the
stated minimum.
Action: Set the value of the init.ora parameter
db_block_size to at least 2K. For XDB to run at its fastest,
set db_block_size to 8K.
