Need advice on tuning about a query?

Question

Hi experts,
I want to tune this query
Before effect
SELECT   NVL (MAX (a.actual_to_date + 1),
                    b.date_of_joining
                   ) AS start_date
          FROM HR_JUDGE_MONTH_SALARY a, HR_JUDGE_MASTER b
         WHERE a.judge_code(+) = b.judge_code AND b.judge_code = :b1
      GROUP BY b.judge_code, b.date_of_joining
call     count       cpu    elapsed       disk      query    current        rows
Parse        0      0.00       0.00          0          0          0           0
Execute    261      0.00       0.00          0          0          0           0
Fetch      261      2.01     133.50      28045     194499          0         261
total      522      2.01     133.51      28045     194499          0         261There are 2 tables involved in this query.
1. tables are not have proper statistics
2. indexes are not analyzed,
so i did the following changes.
select count(*) from HR_JUDGE_MASTER;
select * from user_tables where table_name = 'HR_JUDGE_MASTER';
eXEC DBMS_STATS.gather_table_stats('MOJ_PRD','HR_JUDGE_MASTER');
EXEC DBMS_STATS.GATHER_INDEX_STATS('MOJ_PRD','SYS_C004215')
select count(*) from HR_JUDGE_MONTH_SALARY;
select * from user_tables where table_name = 'HR_JUDGE_MONTH_SALARY';
eXEC DBMS_STATS.gather_table_stats('MOJ_PRD','HR_JUDGE_MONTH_SALARY');
EXEC DBMS_STATS.GATHER_INDEX_STATS('MOJ_PRD','SYS_C004268')after effect
SELECT   NVL (MAX (a.actual_to_date + 1),

Answer 1

i have the whole trace file even though i am not able to identify the "wait".
The whole file i am not able to attach here, it said the beyond the maximum limit.
