-allPublicSynonyms It enables the migration of all public synonyms from an Oracledatabase to an Advanced Server database. If a synonym with the same name already exists in the target database,the existing synonym will be replaced with the migrated version.
-allPrivateSynonyms It enables the migration of all private synonyms from an Oracledatabase to an Advanced Server database. If a synonym with the same name already exists in the target database,the existing synonym will be replaced with the migrated version.
-dropSchema [true|false] 若架构已存在于目标数据库中,则删除此架构 (默认值: false)。
-truncLoad 此选项对目标表禁用任何约束,并且在导入新数据之前先截断表中的数据。此选项只能与 -dataOnly 一起使用。
-safeMode 使用纯 SQL 语句,以安全模式传输数据。
-copyDelimiter 在加载表数据时,指定一个字符作为复制命令中的分隔符。默认值为 \t
-batchSize 指定“批量插入”要使用的“批次大小”。有效值为 1-1000,默认批次大小为 1000,如果出现“内存不足”异常,则可以降低此值

-filterProp 包含表 where 子句的属性文件。
-skipFKConst 跳过外键约束的迁移。
-skipCKConst 跳过检查约束条件的迁移。
-ignoreCheckConstFilter 在缺省的情况下MTK不从Sybase中迁移检查约束和缺省子句,使用这个选项可以关闭这个过滤功能。

-customColTypeMapping LIST 使用以分号分隔的列表表示的自定义类型映射,其中每个条目都使用 COL_NAME_REG_EXPR=TYPE 对来指定,例如 .*ID=INTEGER
-customColTypeMappingFile PROP_FILE 由属性文件表示的自定义类型映射,其中每个条目都使用 COL_NAME_REG_EXPR=TYPE 对来指定,例如 .*ID=INTEGER
-offlineMigration [DDL_PATH] 这将执行脱机迁移并将 DDL 脚本保存在文件中供以后执行。默认情况下,如果要求后跟-offlineMigration 选项以及自定义路径,则脚本文件将保存在用户主文件夹下。
-logDir LOG_PATH 指定用于保存日志文件的自定义路径。默认情况下,日志文件保存在工作目录中的“logs”文件夹下。
-copyViaDBLinkOra 此选项可用来通过使用 dblink_ora COPY 命令复制数据。此选项仅限用在从 Oracle 到 EnterpriseDB 迁移模式中。

-allDomains 从源数据库导入所有域、枚举和复合类型。
-domains LIST 从源数据库导入所选域、枚举和复合类型。 LIST 是一个用逗号分隔的域名称列表,如 -domainsd_email,d_dob, mood
-objecttypes 导入用户定义的对象类型。
-replaceNullChar <CHAR> 如果空字符是列值得一部分,那么通过JDBC协议迁移数据就会失败.这个选项可以使用用户指定的字符来替代空字符串。
-importPartitionAsTable [LIST] 通过使用这个选项能够将Oracle中的分区表以常规表的形式导入到EnterpriseDB中。为了在所选择表集合上的应用规则,在选项后面应跟随以逗号分隔的表名列表。
-enableConstBeforeDataLoad 通过使用这个选项可以在数据导入前重新启用约束(和触发器).当要迁移的表在EnterpriseDB中对应的是一张分区表时,使用这个选项是非常有用的。
-checkFunctionBodies [true|false] 设置为 false 时,将禁用创建函数过程中的函数体验证,从而避免在函数包含向前参考时发生错误。 目标数据库为 Postgres/EnterpriseDB 时适用,默认值为 true。
-retryCount VALUE 指定 MTK 迁移由于跨架构相关性而失败的对象的重试次数。 VALUE 参数应该大于 0,默认值为 2。
-analyze 它将对目标 Postgres 或 Postgres Plus Advanced Server 数据库调用 ANALYZE 操作。 ANALYZE 收集用于有效查询计划的迁移表的统计信息。
-vacuumAnalyze 它将对目标 Postgres或 PostgresPlus Advanced Server 数据库调用 VACUUM 和 ANALYZE 操作。 VACUUM 回收非活动元组存储,ANALYZE 收集用于有效查询计划的迁移表的统计信息。

-truncLoad It disables any constraints on target table andtruncates the data from the table before importing new data. This option canonly be used with -dataOnly.
-safeMode Transfer data in safe mode using plain SQLstatements.
-copyDelimiter Specify a single character to be used asdelimiter in copy command when loading table data. Default is \t
-batchSize Specify the Batch Size to be used by the bulkinserts. Valid values are 1-1000,default batch size is 1000, reduce if you run into Out of Memory exception
-cpBatchSize Specify the Batch Size in MB, to be usedin the Copy Command. Valid value is > 0, default batch size is 8 MB

-customColTypeMappingFilePROP_FILE The custom type mappingrepresented by a properties file, where each entry is specified usingCOL_NAME_REG_EXPR=TYPE pair. e.g. .*ID=INTEGER

-importPartitionAsTable[LIST] Use this option to import Oracle Partitioned table as a normal table inEnterpriseDB. To apply the rule on a selected set of tables, follow the optionby a comma-separated list of table names.
-enableConstBeforeDataLoadUse this option to re-enable constraints (and triggers) before data load. Thisis useful in the scenario when the migrated table is mapped to a partitiontable in EnterpriseDB.
-checkFunctionBodies[true|false] When set to false, it disables validation of the function bodyduring function creation, this is to avoid errors if function contains forwardreferences. Applicable when target database is Postgres/EnterpriseDB, defaultis true.
-retryCountVALUE Specify the number of re-attemptsperformed by MTK to migrate objects that failed due to cross-schemadependencies. The VALUE parameter should be greater than 0, default is 2.
-analyze It invokes ANALYZE operation against a targetPostgres or Postgres Plus Advanced Server database. The ANALYZE collectsstatistics for the migrated tables that are utilized for efficient query plans.
