Heads up for XE upgrade on Windows XP Pro

Question

I am posting this as a "Heads-up" to double check your file system directory structure before running the import during an upgrade from 10gXE to 11gXE. impdp won't create Windows directories for you, and will fail if they are not there.
I perfomed an upgrade from 10gXE to 11gXE using the expdp/impdp instructions in the documentation.
Win XP Pro Version 2002, Service Pack 3
My 10gXE data files had previously been in C:\oraclexe\oradata\xe.
I took the export as instructed.
I uninstalled 10gXE.
I attempted to install 11gXE, which halted because C:\oraclexe still existed.
I renamed C:\oraclexe and the 11gXE installer ran successfully.
I attempted the import as instructed. The first attempt failed because I had data in tablespaces in directories that no longer existed (the 10gXE uninstall removed them).
I found that 11gXE created C:\oraclexe\app\oracle\oradata\XE to hold data files, instead of C:\oraclexe\oradata\xe
Once I manually re-created the directories C:\oraclexe\oradata\xe, the import ran successfully, since it could create tablespaces here as expected.

Hi clcarter,
I am following the install docs which tell you export via the datapump:
expdp user/password full=Y EXCLUDE=SCHEMA:\"LIKE \'APEX_%\'\",SCHEMA:\"LIKE \'FLOWS_%\'\" directory=DUMP_DIR dumpfile=DB10G.dmp logfile=expdpDB10G.log
expdp user/password TABLES=FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ directory=DUMP_DIR dumpfile=DB10G2.dmp logfile=expdpDB10G2.log
Then uninstall 10g, install 11g then run the import:
impdp user/password full=Y directory=DUMP_DIR dumpfile=DB10G.dmp logfile=expdpDB10G1.log
impdp user/password directory=DUMP_DIR TABLE_EXISTS_ACTION=APPEND TABLES=FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ dumpfile=DB10G2.dmp logfile=expdpDB10G1b.log
The trigger in question is just setting a new primary key from a sequence:
create or replace TRIGGER "MYUSER"."MYTRIGGER"
before insert on "MYTABLE"
for each row
begin
if :NEW."MYTABLEID" is null then
select "MYTABLESEQ".nextval into :NEW."MYTABLE" from dual;
end if;
end;
Thanks in advance
Dave
