You are currently browsing the tag archive for the ‘ORA-31693:’ tag.
You may hit with that error code during the export process. I faced with those error on Oracle 12c database.
Complete error messages are:
ORA-31693: Table data object "SCHEMA"."TABLE_NAME_HERE" failed to load/unload and is being skipped due to error: ORA-02354: error in exporting/importing data ORA-01555: snapshot too old: rollback segment number 21 with name "_SYSSMU21_2773200038$" too small
I face with ORA-14460: only one COMPRESS or NOCOMPRESS clause may be specified error message during making Export table from 11.2.0.2 RAC database to 11.2.0.1 RAC database on AIX 6.1.
