In computing, Oracle Coherence (originally Tangosol Coherence) is a Java-based distributed cache and in-memory data grid, intended for systems that require high availability, high scalability and low latency, particularly in cases that traditional relational database management systems provide insufficient throughput, or insufficient performance. It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database workloads. Cause Oracle Data Provider for .NET - Version 12.1.0.2 and later Microsoft Windows x64 (64-bit) Microsoft Windows (32-bit) Symptoms.

The use of an Oracle BI Server event polling table (event table) is a way to notify the Oracle BI Server that one or more physical tables have been updated. Oracle Database (commonly referred to as Oracle RDBMS or simply as Oracle) is a multi-model database management system produced and marketed by Oracle Corporation..

The latest generation, Oracle Database 19c, is available on … As a result, big tables accessed via serial Full Table Scans bypass the Buffer Cache and read data from the Data Files into the users’ Program Global Area (PGA). The Oracle BI Server cache system reads rows from, or polls, the event table, extracts the physical table information from the rows, and purges stale cache entries that reference those physical tables.

This prevents flooding If you have a query that is executed often and reads data that rarely changes, this feature can increase performance significantly. The Exadata Smart Flash Cache is a cache on the cell (storage) server for storing redo-data until this data can be safely written to disk.

Cross-Session PL/SQL Function Result Cache in Oracle Database 11g Release 1. Result Cache is a new feature in Oracle 11g and it does exactly what its name implies, it caches the results of queries and puts it into a slice of the shared pool. Subsequent execution of same query is faster because now the data is being pulled from cache. Serial direct path reads were first introduced in Oracle 11g to prevent wiping out a large number of buffers from the buffer cache by a serial large table scan.

When installing the 12.2 Oracle Data Provider for .Net, the provider is not automatically registered in the Global Assembly Cache (GAC). Example.

Oracle (11g and above) allows the SQL queries to be cached in the SGA and reused to improve performance.It queries the data from cache rather than database. The cross-session PL/SQL function result cache provides a simple way to boost the performance of PL/SQL functions by saving the results of function calls for specific combinations of input parameters in the SGA. Changes Moved to the 12.2 version of the Oracle Provider for .Net. Oracle Database 11g already has a Result Cache technology, which allows you to cache not just table rows or indexes but the results of queries and subqueries themselves. The Exadata storage server comes with a substantial amount of flash storage.
