New Features topic provides the information about the features that are new in this release.

The following features are new in this release:

• Oracle LogMiner

  The CONTINUOUS_MINE functionality of the LogMiner package is obsolete. It was deprecated in Oracle Database 12c release 2 (12.2). There is no replacement functionality.

• REST APIs

  In managed cloud services such as Exalogic Elastic Cloud Software (EECS) and Oracle Data Warehouse Cloud Service (DWCS), users do not have access to the operating system. They only have access to the database service. Loading data and migrating customers from on-premise to such a service is difficult. Customers can upload their Data Pump dump files to the object store and load them into the database using the new object store REST APIs. Impdp client CLI now accepts a new command line parameter called credential.

  The credential parameter is the name of the credential object that contains the user name and password required to access the object store. When a user connects to the database to run impdp, the Datapump layer validates if the credential exists and the user has access to read the credential. If there are any errors, an error is returned back to the impdp client.

• Oracle Data Pump Export and Import

  • The DBAs can now import tablespace files mounted on two different databases as long as the files are set as read-only. KEEP_READ_ONLY and NO_BITMAP_REBUILD are added as TRANSPORTABLE parameter values.

  • The DBAs can now more easily determine how long an export is going to take and discover unforeseen issues not reported by the closure check. The Data Pump Export command-line mode TTS_CLOSURE_CHECK parameter is used to indicate the degree of closure checking to be performed as part of a Data Pump transportable tablespace operation.

  • A new transform parameter, OMIT_ENCRYPTION_CLAUSE is introduced that causes Oracle Data Pump to suppress any encryption clauses associated with objects using encrypted columns.

  • A changed parameter, MAX_DATAPUMP_JOBS_PER_PDB can provide DBAs more control over resource utilization when there are multiple users performing data pump jobs in a given database environment. Default: 100, Range: 0 to 250 or Auto - 50% of SESSIONS.

    A new parameter, MAX_DATAPUMP_PARALLEL_PER_JOB is introduced that provides the database administrators more control over resource utilization when there are multiple users performing data pump jobs in a given database environment.

• Oracle External Tables

  You can now create partitioned hybrid tables using ORACLE_LOADER access driver.
