Job "SYSTEM"."SYS_IMPORT_SCHEMA_02" completed with 3 error(s) at 16:06:16


errors are- (1) one error is of that the TEST user is already exists,
then how to import a schema in already exists user?

(2) 2 errors are because of procedures are created with compilation error.
and i compiled them then i found that the these procedures throws errors because of public sysnonyms.
then how can we include public synonym in export file?

thanks in advance........

(1) You can just ignore this "error" (I think as it as a warning not an error).

(2) You cannot export PUBLIC SYNONYM on schema mode export. Use a (independent) SQL script to do this, using dbms_metadata or querying all_synonyms

ok thanks alot sir,
finally we can create a script of DDL statements for the creation of synonyms and run it independently.
and can we ignore the error message from impdp script?

thanks again....

Before import run the script to create the private synonyms, then the remaining errors may be important.

Dear Neetesh,

You need to avoid:
1) using public synonyms if you are using multiple schemas as there may be a mismatch i.e. EMP public synonym may point to emp table in
scott schema, which is ok, but u might export it along with RAMESH schema, which also has EMP table - which may be of different structure.
This will lead to errors during IMPORT only, as its ok in export db.

2) for best complete schema export/import - don't use SYSTEM id to export - use the source username to export - as this will make sure u
don't pull stuff that is not valid for the schema you are exporting.

3) routine compilation errors are normal during import across db's - just run dbms_utility.compile_schema('schemaName') where schema name
is the name of target user/schema u are importing into. Do this repeatedly till your errors go off - if they don't u are referring to
some other schema in your function/procedure/package -- u need to check it out.
use the user_dependencies view to find the details of the same.

SudheerGodgeri

What does that mean? Which invalid stuff can you export using SYSTEM and schema mode?

And here we know the problem: public sysnonyms. How this part is relevant to the question?

Dear Michel,

1. I assumed that in most development setups, developers inadvertently create objects/public synonyms in SYS/ SYSTEM schemas, often create objects there due to lack
of strick policy about distinct tablespaces for distinct object types, so exporting
as owner ( non SYS/SYSTEM) is the best way to find/purge this dependency.

2. The 31684 - user/object already exists error - will b thrown as you would
normally create the user before importing into it, it's good practice to
create distinct physical layouts rather than have oracle create it .

The 39083 errors - usually either compilation warnings / some dependency on
out of source schema objects - which you must know - you will not if u use
SYS/SYSTEM to export/import as when you import back into different schema in
the same database - you will not get errors due to wrong ("invalid/unplanned")
for dependencies in the target schema, when you import as that schema owner
itself.

Sudheer Godgeri.

1. I would not rely on export/import to detect these errors. Compliance tools should be there to verify. Anyway, I wonder how a developer could create any object in SYS or SYSTEM schema or any schema as developers do NOT create objects, designers describe the object which should be created by DBA-like account NOT by developers.

2. Why should I create the user before importing? When I create the database objects of an application, why should I not use an import that also creates the important accounts for the application (those that are used to manage the application objects, including users)?

I don't understand you last paragraph. Post an example.

Regards
Michel
