The Data Pump Import utility provides a mechanism for transferring data objects
between Oracle databases. The utility is invoked with the following command:

Example: impdp scott/tiger DIRECTORY=dmpdir DUMPFILE=scott.dmp

You can control how Import runs by entering the 'impdp' command followed
by various parameters. To specify parameters, you use keywords:

Format: impdp KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
Example: impdp scott/tiger DIRECTORY=dmpdir DUMPFILE=scott.dmp

USERID must be the first parameter on the command line.

Keyword Description (Default)
------------------------------------------------------------------------------
ATTACH Attach to existing job, e.g. ATTACH [=job name].
CONTENT Specifies data to load where the valid keywords are:
(ALL), DATA_ONLY, and METADATA_ONLY.
DIRECTORY Directory object to be used for dump, log, and sql files.
DUMPFILE List of dumpfiles to import from (expdat.dmp),
e.g. DUMPFILE=scott1.dmp, scott2.dmp, dmpdir:scott3.dmp.
ENCRYPTION_PASSWORD Password key for accessing encrypted column data.
This parameter is not valid for network import jobs.
ESTIMATE Calculate job estimates where the valid keywords are:
(BLOCKS) and STATISTICS.
EXCLUDE Exclude specific object types, e.g. EXCLUDE=TABLE:EMP.
FLASHBACK_SCN SCN used to set session snapshot back to.
FLASHBACK_TIME Time used to get the SCN closest to the specified time.
FULL Import everything from source (Y).
HELP Display help messages (N).
INCLUDE Include specific object types, e.g. INCLUDE=TABLE_DATA.
JOB_NAME Name of import job to create.
LOGFILE Log file name (import.log).
NETWORK_LINK Name of remote database link to the source system.
NOLOGFILE Do not write logfile.
PARALLEL Change the number of active workers for current job.
PARFILE Specify parameter file.
QUERY Predicate clause used to import a subset of a table.
REMAP_DATAFILE Redefine datafile references in all DDL statements.
REMAP_SCHEMA Objects from one schema are loaded into another schema.
REMAP_TABLESPACE Tablespace object are remapped to another tablespace.
REUSE_DATAFILES Tablespace will be initialized if it already exists (N).
SCHEMAS List of schemas to import.
SKIP_UNUSABLE_INDEXES Skip indexes that were set to the Index Unusable state.
SQLFILE Write all the SQL DDL to a specified file.
STATUS Frequency (secs) job status is to be monitored where
the default (0) will show new status when available.
STREAMS_CONFIGURATION Enable the loading of Streams metadata
TABLE_EXISTS_ACTION Action to take if imported object already exists.
Valid keywords: (SKIP), APPEND, REPLACE and TRUNCATE.
TABLES Identifies a list of tables to import.
TABLESPACES Identifies a list of tablespaces to import.
TRANSFORM Metadata transform to apply to applicable objects.
Valid transform keywords: SEGMENT_ATTRIBUTES, STORAGE
OID, and PCTSPACE.
TRANSPORT_DATAFILES List of datafiles to be imported by transportable mode.
TRANSPORT_FULL_CHECK Verify storage segments of all tables (N).
TRANSPORT_TABLESPACES List of tablespaces from which metadata will be loaded.
Only valid in NETWORK_LINK mode import operations.
VERSION Version of objects to export where valid keywords are:
(COMPATIBLE), LATEST, or any valid database version.
Only valid for NETWORK_LINK and SQLFILE.

The following commands are valid while in interactive mode.
Note: abbreviations are allowed

Command Description (Default)
------------------------------------------------------------------------------
CONTINUE_CLIENT Return to logging mode. Job will be re-started if idle.
EXIT_CLIENT Quit client session and leave job running.
HELP Summarize interactive commands.
KILL_JOB Detach and delete job.
PARALLEL Change the number of active workers for current job.
PARALLEL=<number of workers>.
START_JOB Start/resume current job.
START_JOB=SKIP_CURRENT will start the job after skipping
any action which was in progress when job was stopped.
STATUS Frequency (secs) job status is to be monitored where
the default (0) will show new status when available.
STATUS[=interval]
STOP_JOB Orderly shutdown of job execution and exits the client.
STOP_JOB=IMMEDIATE performs an immediate shutdown of the
Data Pump job.

结果正确的写法应该是这样:

userid=sla
directory=EXP_DIR
dumpfile=sla.dmp
table_exists_action=replace
EXCLUDE=TABLE:"='sla_dbconf'"

估计是一个bug.
