Hi Sting,
You can increase the processes of "Update and Spool" by setting below parameters in RZ10 in "Instance Profile".
Update --- rdisp/wp_no_vb
Spool ------rdisp/wp_no_spo
Enter the number (that how many process you need) in the value field
Increasing the "enque" process is not recommended and more over not needed. Usually in all servers we maintain only one "enque" process. One enque process can handle entaire server.
Still you require to increase set below parameter and value
Enque ---- rdisp/wp_no_enq = 2
Note: After setting these values, you need to restart the server/instance in order to effect.
Ensure you have enough Memory (CPU and SWAP) to set these values
Hope you got the enough information. Give me points if my message to you.
Regards
