SYMPTOMS
The following message isreported in the alert log:
WARNING: Granules ofpga_aggregate_target %d cannot be more than memory_target (%d) -sga_target (%d) or min_sga(%d)
CHANGES
The MEMORY_TARGET andSGA_MAX_SIZE or SGA_TARGET parameters are set.
CAUSE
This warning message israised because the MEMORY_TARGET/MEMORY_MAX_TARGET andSGA_MAX_SIZE/SGA_TARGET parameters are set the same.
However, in Oracle 11g theMEMORY_TARGET parameter defines the total amount of memory thatOracle can use, which incorporates both SGA and PGA areas.
Therefore if these are setthe same as the SGA_MAX_SIZE/SGA_TARGET parameters then this leavesno memory available for the PGA, and hence this warning message israised.
SOLUTION
Ensure that theMEMORY_TARGET/MEMORY_MAX_TARGET parameter settings are set to atleast the sum of SGA_MAX_SIZE/SGA_TARGET plus thePGA_AGGREGATE_TARGET parameter.
