Database import errors

Question

Hello everyone!
I have some problems with importing a database, I can't find the answer so I turn to you people.
I've tried to import to an empty database (with the necessary tables of course) but that gave more errors, so I created the important schemes and tables with the sqls from the original database.
The original database is working, everything is in there so I don't really understand the "not found" or "does not exists" errors, because I think Oracle is supposed to do the import in such a way, that the connections between objects doesn't get lost, so the database is built up from the bottom.
The machine I export the data from:
CentOS 5.5
Oracle Database 10g Release 10.2.0.3.0 - 64bit Production
NLS_CHARACTERSET EE8MSWIN1250
nls_length_semantics string BYTE
The machine I try to import data:
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
NLS_CHARACTERSET AL32UTF8
nls_length_semantics string CHAR
(Before you ask, we are Platinum Partners that is why we have Enterprise Edition, we can use it but we don't have support)
The export command: expdp system/password full=y directory=dmpdir dumpfile=export.dmp logfile=export.log
Job "SYSTEM"."SYS_EXPORT_FULL_01" completed successfully at: 14:46:34
The import command: impdp system/password full=y directory=dmpdir table_exists_action=append dumpfile=export.dmp logfile=import_db.log
Job "SYSTEM"."SYS_IMPORT_FULL_01" completed with 999 error(s) at 15:55:46
The errors I don't understand:
ORA-39083: Object type JOB failed to create with error:
ORA-00001: unique constraint (SYS.I_JOB_JOB) violated
ORA-31693: Table data object "SYSMAN"."MGMT_JOB_PURGE_POLICIES" failed to load/unload and is being skipped due to error:
ORA-00001: unique constraint (SYSMAN.PK_MGMT_JOB_PURGE_POL) violated
ORA-31693: Table data object "SYSMAN"."MGMT_JOB_SINGLE_TARGET_TYPES" failed to load/unload and is being skipped due to error:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
ORA-31693: Table data object "SYSMAN"."MGMT_CREDENTIALS2" failed to load/unload and is being skipped due to error:
ORA-29913: error in executing ODCIEXTTABLEFETCH callout
ORA-28239: no key provided
ORA-31693: Table data object "SYSMAN"."MGMT_HC_VENDOR_SW_COMPONENTS" failed to load/unload and is being skipped due to error:
ORA-29913: error in executing ODCIEXTTABLEFETCH callout
ORA-02291: integrity constraint (SYSMAN.VNC_VND_FK) violated - parent key not found
KUP-11007: conversion error loading table "SCHAME_NAME"."TABLE_NAME"
ORA-12899: value too large for column COLUMN_NAME (actual: 3767, maximum: 4000)
KUP-11009: data for row: COLUMN_NAME: 0X'4146414245484E41507C4146414245484E41507CC166616265'
And many objects are missing, triggers, sequences, indexes. Much more than the number of errors in the import_db.log.
I hope someone can help me.
Thank you in advance,
Adam

Hi, and welcome to OTN!
Firstly, try to create the new database with the same character set and nls_length_semantics,
The machine I export the data from:
CentOS 5.5
Oracle Database 10g Release 10.2.0.3.0 - 64bit Production
NLS_CHARACTERSET EE8MSWIN1250
nls_length_semantics string BYTE
The machine I try to import data:
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
NLS_CHARACTERSET AL32UTF8
nls_length_semantics string CHARThis could be responsible for the error:
KUP-11007: conversion error loading table "SCHAME_NAME"."TABLE_NAME"
ORA-12899: value too large for column COLUMN_NAME (actual: 3767, maximum: 4000)Secondly, I often find it better to not do a full export/import when moving between databases, and especially when moving between different database versions. The importing database have a (almost) fully populated sys and sysman-schema, and the full import is trying to add stuff to those schemas, causing all kind of violations.
So, could you try to either export only the schemas that you're interested in (the user schemas), or just import these from the full export, and post the results?
