Disclaimer listing files with the external table preprocessor in 11g The external table preprocessor was introduced in 11g Release 1 patchset The most obvious use for such a feature is to enable compressed files to be queried directly from external tables and this is described in another oracle-developer. Another obvious use for the preprocessor is to solve the common problem of how to list files in directories from within Oracle i.

Working with a Self-Managed Oracle Database as a Source for AWS DMS

Binary Reader does not. In general, use Oracle LogMiner for migrating your Oracle database unless you have one of the following situations: You need to run several migration tasks on the source Oracle database. The volume of changes or the redo log volume on the source Oracle database is high.

You are migrating LOBs from an Oracle These update statements are not supported by Oracle LogMiner. These statements are not supported by Oracle LogMiner.

This attribute specifies whether to use LogMiner or Binary Reader to access the transaction logs. You specify an extra connection attribute when you create the source endpoint.

Multiple extra connection attribute settings should be separated by a semicolon. LogMiner is used by default, so you don't have to explicitly specify its use. The enable Binary Reader to access the transaction logs, add the following extra connection attribute.

When you create the source endpoint, the password field needs to have both passwords, the source user password and the ASM password.

To grant individual table to user

For example, the following extra connection attribute format is used to access a server that uses Oracle ASM. For example, the following works in the password field.

An example is when you access the redo logs without using LogMiner. Following, you can find out about the privileges and configurations you need to set up when using a self-managed Oracle database with AWS DMS. If you add supplemental logging and you use a specific table list, grant ALTER for each table in the list.

Set up supplemental logging — If you are planning to use the source in a CDC or full-load plus CDC task, then you need to set up supplemental logging to capture the changes for replication.

There are two steps to enable supplemental logging for Oracle. First, you need to enable database-level supplemental logging. Doing this ensures that the LogMiner has the minimal information to support various table structures such as clustered and index-organized tables.

Second, you need to enable table-level supplemental logging for each table to be migrated. To enable database-level supplemental logging Run the following query to determine if database-level supplemental logging is already enabled. The return result should be from GE to 9.

Otherwise, you can use the steps following for each table in the migration. If there is no primary key and no unique index, supplemental logging must be added on all columns.

Run the following query to add supplemental logging to all columns. In these cases, add supplemental logging on the source table columns that make up the target table primary key or unique index. If you change the target table primary key, you should add supplemental logging on the selected index's columns, instead of the columns of the original primary key or unique index.

Add additional logging if needed, such as if a filter is defined for a table. If a table has a unique index or a primary key, you need to add supplemental logging on each column that is involved in a filter if those columns are different than the primary key or unique index columns.

Set up archive retention — Run the following to retain archived redo logs of your Oracle database instance. Make sure that you have enough storage for the archived redo logs during the migration period. In the following example, logs are kept for 24 hours.

To enable database-level supplemental logging Run the following query to enable database-level supplemental logging. The following command creates a table and adds supplemental logging.

Add supplemental logging to the table using the following command. The following extra connection attributes should be included with the connection information when you create the Amazon RDS for Oracle source endpoint:Articles and utilities for Oracle developers. listing files with the external table preprocessor in 11g.

The external table preprocessor was introduced in 11g Release 1 (patchset ) and formally documented in 11g Release 2. Note: If external tables are created with NOLOG then granting READ on the DIRECTORY object is sufficient.

If an external table is created without the NOLOG syntax then both READ and WRITE must be granted to SELECT from it. Prior to version 10g, external tables were READ plombier-nemours.com, update, and delete could not be performed.
