ORA-00955: name is already used by an existing object

ashwan_12Dec 8 2016 — edited Dec 9 2016

DB Version 12.1.02 EE

I am doing import export schemas and while import many schemas . Import failed with  ORA-00955 error. 

import log:

+++++++++++++++++++++++++++++++++++

ORA-39083: Object type CONSTRAINT:"RQF"."CV_ACCESS_AUD_UK2" failed to create with error:

ORA-00955: name is already used by an existing object

Failing sql is:

ALTER TABLE "RQF"."CV_ACCESS_AUD" ADD CONSTRAINT "CV_ACCESS_AUD_UK2" UNIQUE ("CA_CV_ID", "CA_GROUP_UID", "CA_EMPLOYEE_NO", "AUD_UID") USING INDEX (CREATE UNIQUE INDEX "RQF"."CV_ACCESS_AUD_UK1" ON "RQF_CV"."CV_ACCESS_AUD" ("CA_CV_ID", "CA_EMPLOYEE_NO", "CA_GROUP_UID", "AUD_UID") PCTFREE 10 INITRANS 2 MAXTRANS 255  STORAGE(INITIAL 65536 NEXT 10

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I checked with import DB. This index(CV_ACCESS_AUD_UK1) already in the DB under RQF schema and that was created through import automatically.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Not sure why This happen.

Can any one explain it.
