When viewing SQL statements in Top Activity in OEM, I am only able to see the Explain Plan for the most recent statement. Is there a setting to increase the number execution plans kept?

I've installed Grid Control (aka OMS) 10.2.0.5 and try to look at the Database Performance. But instead of information I receive headers and blank picture in the place where usually all charts are shown. As a matter of fact it looks like the page tries to access that data source, but fails in that and shows just a symbol of picture that was not loaded and all menus from that page.

Im not sure of this, but seeing different plans for same SQL.
select sql_text from v$sqlarea where sql_id='92mb4z83fg4st'; <---TOP SQL from AWR
SELECT /*+ OPAQUE_TRANSFORM */ "ENDUSERID","LASTLOGINATTEMPTTIMESTAMP","LOGINSOURCECD","LOGINSUCCESSFLG",
"ENDUSERLOGINATTEMPTHISTORYID","VERSION_NUM","CREATEDATE"
FROM "BOMB"."ENDUSERLOGINATTEMPTHISTORY" "ENDUSERLOGINATTEMPTHISTORY";
[code]....
multiple execution plns for the sql_id from AWR,i have following questions
1.which plan is opimizer tcurrently using ?
2.how to make sure optimizer to pick right plans
SQL> select * from table(dbms_xplan.display_awr('fb0p0xv370vmb')) ;
PLAN_TABLE_OUTPUT
SQL_ID fb0p0xv370vmb

I am executing the query below:
INSERT INTO temp_vendor(vendor_record_seq_no,checksum,rownumber,transaction_type,iu_flag)
SELECT /*+ USE_NL ( vd1 ,vd2 ,vd3 ) leading ( vd1 ,vd2 ,vd3 , tvd) */ vd1.vendor_record_seq_no, tvr.checksum, tvr.rownumber, tvr.transaction_type, 'U'
FROM vendor_data vd1,
vendor_data vd2,
vendor_data vd3,
(SELECT rownumber,
[code]....
It is taking different approaches (execution plans) while executing for same set of parameters. Due to which sometimes it executes successfully, but sometimes it fills all TEMP space and get failed. I am pasting both the execution plan (different from expalin plan) below:
I. Successfull Execution Plan:
------------------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
------------------------------------------------------------------------------------------------------------------------
| 0 | INSERT STATEMENT | | | | 65612 (100)| | | |
|* 1 | HASH JOIN | | 1 | 6121 | 65612 (1)| 00:13:08 | | |
[code]....
II. Failed with TEMP space Execution Plan:
--------------------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
--------------------------------------------------------------------------------------------------------------------------
| 0 | INSERT STATEMENT | | | | 1967 (100)| | | |

We have a query which makes Oracle behave very strangely. It is a straight-forward join between four tables of about 30.000 rows each, with some simple comparisons and some NOT LIKE:s.
When we run this query, it either takes about 1 second or more than 1.000 seconds to run and return the approximately 5.000 rows of the result. If we run the same query over and over again, it fluctuates back and forth between two different execution plans, apparently at random, 3 times out of 4 selecting the 1.000 second version and 1 time out of 4 the 1 second version.
There are no other connections to the database, the schema is not modified, the data is identical, the query is identical, and the response is identical, but the execution time alternates between 1 second and 1.000 seconds.On the same database instance we have another schema which is identical, but with slightly less data, which is used for development. The 1.000 second run times did not happen in that schema, but only in the test system's database.
Therefore we would REALLY like to understand what happens and why, so that we can avoid triggering this in the future. We could try locking the 1 second execution plan, but then we're afraid of doing the same thing wrong again in the future.
Here are the two execution plans that Oracle switches between, more or less at random:
Rows (1st) Rows (avg) Rows (max) Row Source Operation
---------- ---------- ---------- ---------------------------------------------------
5455 5455 5455 HASH JOIN (cr=15663 pr=10536 pw=0 time=855673 us cost=82273 size=2707430769293 card=14028138701)
79272 79272 79272 TABLE ACCESS FULL GROUPS (cr=1008 pr=0 pw=0 time=22154 us cost=277 size=10693 card=289)
[code]...
Rows (1st) Rows (avg) Rows (max) Row Source Operation
---------- ---------- ---------- ---------------------------------------------------
5455 5455 5455 HASH JOIN (cr=15664 pr=0 pw=0 time=778178696 us cost=30838477 size=741611997206725 card=3842549208325)
375411 375411 375411 TABLE ACCESS FULL GROUP_GROUPS_FLAT (cr=3782 pr=0 pw=0 time=51533 us cost=1029 size=25152738 card=375414)
[code]...
The query:
select g.ucid, a.ucid
from account a, groups g, group_members gm, group_groups_flat ggf
where a.ucid = gm.ucid_member
and gm.ucid_group = ggf.ucid_member
[code]...
And excerpts from the schema:
CREATE TABLE "PDB"."GROUPS"
(
"UCID" VARCHAR2(256 BYTE),
"UNIX_GID" NUMBER(*,0),
[...]
[code]...
When we use the AUTOTRACE / EXPLAIN PLAN we can see the (estimated) best execution plan the Optimizer found for our SQL Command. Is there a way to display all alternate execution plans the Optimizer has considered ?

We have the Oracle Enterprise Manager Grid Control 10.2.0.5. We recently upgraded our Databases from 10.2.0.3 to 10.2.0.4 and since then we are having this problem.
Whenever i click an Agent on the Grid Control it gives me this error: "Communication between the Oracle Management Service host to the Agent host is unavailable. Any functions or displayed information requiring this communication link will be unavailable. For example: deleting/configuring/adding targets, uploading metric data, or displaying Agent home page information such as Agent to Management Service Response Time (ms)."
I get the same error when i try to configure a host or a database.
Don't know what is wrong

View -1 Replies View RelatedIn my recent performance improvement tasks I was experimenting with Parallel hints. I have been getting good results with them, however the question arises "How is Parallel degree proportionate to number of CPUs used during execution?
/*+ parallel(emp_tab,8) */
Oracle Version: Oracle 10g
OS : UNIX
Client OS: Windows XP
V$PARAMETER VARIABLES as follows:
Total CPUs available: 10
No of CPUs per core: 2
Max parallel : 100
Min Parallel : 5
Question 1: So how do I map the degree of 8 with CPUs. I believe that degree of 8 does not mean its going to use 8 CPUs. If so, how do I prove it. I tried SQL_TRACE and cpu comes 0. And I believe its not the CPU count.
Question2: How do I know how many CPUs were used to execute a SQL query ?

In "Recovery Settings", I have a "Flash Recovery Area Location" defined (path local to the DB -i.e. the server that the DB resides on), a "Flash Recovery Area Size" of 4 defined, and a Flashback Retention Time of 24 hours defined. Everything else is riding default values.
In "Backup Settings", there's nothing defined. Everything here is riding default values. As I understand it, not specifying a Disk Backup Location is fine so long as the Flash Recovery Area is defined. All the local services are turned on (scheduling, etc.).
If it's relevant, I mirrored the recovery/backup settings in UAT to the same as PROD, but changed what I needed to in order to accommodate the UAT environment (e.g. paths, etc.)
I want to manage my database remotely, through Internet. Is it possible to do that with OEM? Where can I find information related to this? Is there another monitoring software that allows me to perform this?
