Symptoms

Refreshing MVs with DBMS_REFRESH  runs very slowly.

Dropping the involved Spatial Indexes improves performance greatly, but a permanent solution is needed.

Upon checking involved processes with "ps -ef|grep csdgdilt|grep _j0" we find that these are executing:

SELECT /* chk_journal_reg */

ROWID

FROM "MDSYS"."SDO_TXN_JOURNAL_REG"

WHERE sid = :1

AND sdo_txn_idx_id = :2

AND indexptniden = :3

AND operation = :4

AND rid = :5

Changes
