Poor performance when synchronizing or deploying a mapping with OWB 11.2.
Tracing the session with SQL developer, one query in particular seems to be the major performance issue:
/*+ index(allinterlink AllInterLink_PK) */
WHERE (WORKSPACEID, LINKFROM) IN
SELECT WORKSPACEID, ELEMENTID FROM CHANGELOG WHERE ROWNUM>0
It is doing an index full scan on ALLINTERLINK_PK.
