Predefined Database Service Names for Autonomous Transaction Processing

The tnsnames.ora file provided with the credentials zip file contains five database service names identifiable as tpurgent, tp, high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Transaction Processing.

• tpurgent: The highest priority application connection service for time critical transaction processing operations. This connection service supports manual parallelism.

• tp: A typical application connection service for transaction processing operations. This connection service does not run with parallelism.

• high: A high priority application connection service for reporting and batch operations. All operations run in parallel and are subject to queuing.

• medium: A typical application connection service for reporting and batch operations. All operations run in parallel and are subject to queuing. Using this service the degree of parallelism is limited to four (4).

• low: A lowest priority application connection service for reporting or batch processing operations. This connection service does not run with parallelism.

DELETE_FILE Procedure

This procedure removes the specified file from the specified directory on Autonomous Data Warehouse.

CREATE_CREDENTIAL Procedure

This procedure stores Cloud Object Storage credentials in the Autonomous Data Warehouse database. Use stored credentials for data loading or for querying external data residing in the Cloud.

PUTJDBJECT Procedure

This procedure copies a file from Autonomous Data Warehouse to the Cloud Object Storage. The maximum file size allowed in this procedure is 5 gigabytes (GB).

VALIDATE EXTERNAL TABLE Procedure

This procedure validates the source files for an external table, generates log information, and stores the rows that do not match the format options specified for the external table in a badfile table on Autonomous Data Warehouse.

CREATE_EXTERNAL_TABLE Procedure

This procedure creates an external table on files in the Cloud. This allows you to run queries on external data from Autonomous Data Warehouse.

To use Data Pump from ADB, a credential identifying the Object Storage bucket to use must be defined with a DBMS_CLOUD.CREATE_CREDENTIAL function. This will allow ADB to access objects that are stored in the object store , including dump files. To export an existing database to prepare for import into ADB, use the XTP command and add the ex elude option for database functionality that is not recommended or supported in ADB. This will prevent errors during the imp oil process.

This process is not automatic. And if the logs are not moved, you will receive a warning when running the MDB that the logs are not there. In this example, we're

moving the log import.log to object store with a DBMS_CLOUD.PUT_OBJECT command.

VALIDATE_EXTERNAL_TABLE Procedure

This procedure validates the source files for an external table, generates log information, and stores the rows that do not match the format options specified for the external table in a badfile table on Autonomous Database. The overloaded form enables you to use the operation_id parameter.

PUT_OBJECT Procedure

This procedure copies a file from Autonomous Database to the Cloud Object Storage. The maximum file size allowed in this procedure is 5 gigabytes (GB)

DELETE FILE Procedure

This procedure removes the specified file from the specified directory on Autonomous Database.

CREATE_EXTERNAL_TABLE Procedure

This procedure creates an external table on files in the Cloud. This allows you to run queries on external data from Autonomous Database.

"If the Autonomous Exadata Infrastructure resource doesn't have a customized schedule, its maintenance schedule will be automatically modified so that it precedes the Autonomous Container Database schedule you define."
