pga_aggregate_target more than pga_aggregate_limit

Hello experts,

                       Recently we hit below error from a 12c release 2 database.

ORA-04036: PGA memory used by the instance exceeds PGA_AGGREGATE_LIMIT

pga_aggregate_limit was 6000MB and one of senior dba suggested to put PGA_AGGREGATE_TARGET as 30GB which is 2 times of SGA_MAX_SIZE.

As far as I know PGA_AGGREGATE_LIMIT is hard limit so even though you set higher pga_aggregate_target process can not allocate memory more than pga_aggregate_limit.

Please correct me if I am wrong?

Regards
