    HCC Locking issue

      Hi All,

      Oracle Says, DML operation on a single row from a table will lock the whole Compression Unit, when the table is in Hybrid Columner Compression.
      in this case, Does HCC is recommended for OLTP database?

      If yes, How about the Locking issue is handled on a table in OLTP HCC.
