Need understanding on the ADDM

Question

Hi,
Db version 11.2.0.3
EBS version 12.1.3
OS : Linux
I have 2 SEV-1 SR's going on with Oracle on which we are working with them. I ran a ADDM from yesterday Morning till today afternoon( Almost 25 Hours).
My understanding :
1. Update query 85ag5gkm9wzmb is taking maximum of time and resources ( One SR is for this - this is Autoinvoice Master Program).
2. SGA and PGA are undersized. Current SGA is 24Gb and PGA is 6Gb. Do I really need to increase SGA and PGA ? My previous has been that on increasing
SGA/PGA to suggested value , it will further prompt for increasing.
3. SYS.DBMS_SPACE.AUTO_SPACE_ADVISOR_JOB_PROC needs some action from my end, should I disable this job , what does it really do ? i am trying to figure that out ,
any help on this will be appreciated.
Please confirm if my understanding is correct and other suggestion/inputs you can provide. Also please suggest how to find if I/O is a bottleneck in the system ? I can see db file sequential read and db file scattered reads in the AWR but they are mostly by the update statement 85ag5gkm9wzmb.
Below is the ADDM for reference.

      The SQL spent 100% of its database time on CPU, I/O and Cluster waits.
      This part of database time may be improved by the SQL Tuning Advisor.
   Rationale
      Database time for this SQL was divided as follows: 100% for SQL
      execution, 0% for parsing, 0% for PL/SQL execution and 0% for Java
      execution.
   Rationale
      SQL statement with SQL_ID "85ag5gkm9wzmb" was executed 20 times and had
      an average elapsed time of 9763 seconds.
   Rationale
      Top level calls to execute the PL/SQL statement with SQL_ID

Hi Karan,
If your DB node has 48 GB and there are no other applications/program running on the server than I believe you still have for room for SGA/PGA resize.
GSS was scheduled to run at 20% till last week ( runs every week) while i just made it to run for auto_sample_size by giving the percent as 0. I have checked and found that most of the tables had good stats , though one of the programs has started to take too much time after that. So for now i have reverted it back to 20%.
10% - 20% is the percentage which I usually go with and this works well for me. Anyways that being said 10% default would do the trick in most cases.
The update statement which is causing the trouble is a seeded oracle program so we have checking that with oracle. ( Auto_invoice_master).
Yes as recommended, Please get confirmation from SR as well.
