Here we are reducing the UPD wp and increasing DIA wp.

Login as <sid>adm and go to profile path by cdpro command.
There we will find a file with naming convention *DVEBMGS*<instance_number>

Edit the values of this file by vi editor command.

Initially update (vp) value was 3 and 2 respectively. It has been reduced to 2 and 1 resp.
