| CAUSE | The specified value of SGA_TARGET was not compatible with current settings of PGA_AGGREGATE_TARGET and MEMORY_TARGET/MEMORY_MAX_TARGET. |
| ACTION | Set SGA_TARGET to be no more than the difference of MEMORY_TARGET/MEMORY_MAX_TARGET and PGA_AGGREGATE_TARGET. Also ensure that the current PGA memory used for non-auto workareas is low. |
