Hi,
See below which I executed in my database (11.2)
You are getting the error because you are using ROLLBACK TO <Savepoint_Name> after executing the COMMIT. After commiting savepoints which were created previously will not exist.
SQL> create table test (num NUMBER);
Table created
SQL> insert into test values(1);
1 row inserted
SQL> insert into test values(9);
1 row inserted
SQL>  savepoint a;
Savepoint created
SQL> insert into test values(7);
1 row inserted
SQL>  update test set num=100 where num=9;
1 row updated
SQL>  savepoint b;
Savepoint created
SQL> delete from test where num=1;
1 row deleted
SQL> commit;
Commit complete
SQL> delete from test where num=1;
0 rows deleted
SQL> rollback to savepoint a;
rollback to savepoint a
ORA-01086: savepoint 'A' never established in this session or is invalid
SQL> If I remove COMMIT then SAVEPOINT will exist
SQL>  insert into test values(1);
1 row inserted
SQL>  insert into test values(9);
1 row inserted
SQL>   savepoint a;
Savepoint created
SQL>  insert into test values(7);
1 row inserted
SQL>   update test set num=100 where num=9;
1 row updated
SQL>   savepoint b;
Savepoint created
SQL>  delete from test where num=1;
1 row deleted
SQL>  delete from test where num=1;
0 rows deleted
SQL>  rollback to savepoint a;
Rollback complete
