The idea of pluggable databases (PDBs) was introduced in Oracle Databases 12c Release 1 (various databases sharing one database instance). This function addresses help for encrypted tablespaces that are also to generally be migrated utilizing cross-platform transportation.
The separation of OLTP and read operations within an Oracle Flex Cluster architecture permits speedy reconfiguration of study-only situations signing up for and leaving the cluster, in addition to successful updates on the buffer cache on People circumstances.
In this particular release, it is possible to determine a white checklist on individual subprograms within a offer. The Obtainable BY clause specifies a list of PL/SQL units which have been regarded Safe and sound to invoke the subprogram, and blocks all others.
All dependent materialized views about the source table must be completely refreshed just after redefinition completes, expanding some time in the event the desk is completely usable. Refreshing the materialized views in the course of the redefinition course of action eliminates time to perform a complete refresh at the tip.
This feature enhances the extensible indexing framework in Oracle Database to help system-managed composite (multi-column) area indexes. The object identifier is returned to extensible indexing get in touch with out functions to help parallelism.
Through the implementation of this conventional, raster information saved in Oracle Spatial and Graph could be manufactured available to an array of purposes online.
Nil glitches noted to programs for new, incoming work and present perform when servicing is in development.
The new parameter DATA_GUARD_SYNC_LATENCY lets you figure out just how long the first database ought to await a response from several synchronous standby databases throughout redo transportation. The present NET_TIMEOUT redo transport attribute means that you can specify how much time the primary databases must anticipate a reaction from Just about every synchronous standby database. When multiple synchronous standby database Places are configured, the principal database will have to await each of the synchronous standby databases to admit receipt from the redo or exceed look at more info their person NET_TIMEOUT time period right before continuing. This new parameter is worldwide for all synchronous standby database destinations and defines the maximum amount of time (in seconds) that the principal database must hold out right before disconnecting subsequent Locations immediately after a minimum of 1 synchronous standby databases has acknowledged receipt of your redo.
These enhancements enable highly effective in-database raster analysis and picture processing on very big (terabyte and petabyte scale) sets of raster imagery without demanding movement of information to mid-tier servers or client applications.
Area tags are extracted from text data and they are matched with famous put names working with Oracle Text and enhanced with other geographic information associated with the nicely know put names.
This attribute allows consumers to script the generation of standby databases in the quite simple fashion from a command-line interface.
