This is the output from the SHOW=Y run of imp for the dump file in question:
REM CREATE TABLE "NORMAN"."PARENT" ("ID" NUMBER(5, 0), "STUFF"
REM VARCHAR2(100)) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
REM TABLESPACE "USERS" LOGGING NOCOMPRESS ;
CONNECT NORMAN;
CREATE UNIQUE INDEX "NORMAN"."U_PARENT" ON "PARENT" ("STUFF" ) PCTFREE 10
INITRANS 2 MAXTRANS 255 TABLESPACE "USERS" LOGGING ;
REM ALTER TABLE "NORMAN"."PARENT" ADD CONSTRAINT "U_PARENT" UNIQUE
REM ("STUFF") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 TABLESPACE
REM "USERS" LOGGING ENABLE ;
Which does actually answer the question I was wanting to know, the Unique constraints are not enabled in NOVALIDATE mode. Sigh!
Cheers,
