Upgrade your Grid Infrastructure at first. Would spinning bush planes' tundra tires in flight be useful? When INMEMORY_SIZE is greater than 0, the Resource Manager is automatically enabled. Just for comparison, between 19.8.0 and 19.9.0 you couldnt find any new non-underscore parameter. IM expressions can greatly improve the performance of analytic queries that use computationally intensive expressions and access large data sets. These articles were helpful. Still these values will be autotuned and PGA_AGGREGATE_TARGET will be initialized with value of (MEMORY_TARGET-SGA_TARGET). SGA_TARGET will be initialized to a value of (MEMORY_TARGET-PGA_AGGREGATE_TARGET). Prior to version 9i, there was only pfile, but still might be preferred but the preference is mainly for backward compatibility with the older releases. SGA_TARGET parameter is a dynamic parameter, SGA_MAX_SIZE is a static parameter and cannot be changed immediately. Misc |
You can query it using the following query from the root container. This feature significantly enhances partitioning for Big Data SQL, where large portions of a table can reside in external partitions.
