One of our RAC databases currently shows high values for the "enq: PS - contention" wait event on two instances out of four:

   INST_ID EVENT                 TOTAL_WAITS TOTAL_TIMEOUTS
TIME_WAITED AVERAGE_WAIT TIME_WAITED_MICRO EVENT_ID
---------- --------------------- ----------- --------------
----------- ------------ ----------------- ----------
         4 enq: PS - contention        69854              0
2389            0          23890039 2071012023
         3 enq: PS - contention       311544         144523
7487132           24        7.4871E+10 2071012023
         2 enq: PS - contention        70269              8
2212            0          22115604 2071012023
         1 enq: PS - contention       257011         147468
7639045           30        7.6390E+10 2071012023

I searched around, but cannot find any documentation on this wait event. What is this wait event? (A pointer to doc is fine as well.)

Kind regards,
