DB: Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production
OS: Red Hat Enterprise Linux Server release 7.6 (Maipo)
I'm following the Doc: The Database Migration Assistant for Unicode (DMU) Tool ( Doc ID 1272374.1 )
Plan to convert:
NLS_CHARACTERSET from AR8MSWIN1256 to AL32UTF8
NLS_NCHAR_CHARACTERSET is UTF8 (no change)
I have cleansed all the user application data.. (Modified the datatype semantics lenght as per the recommendation by DMU)
I am not sure how to proceed with the metadata cleansing?
Message from DMU: The table contains user data that cannot be successfully converted to Unicode.
Table Column Name: SYS**.WRI$_ADV_OBJECTS.**ATTR5
Any kind of help is appreciated.
