Server is firing two queries for grandtotal ?

I have a report and added grand totals to it.
I checked the queries in session monitor before and after adding the grand total.
previously, single query was sent to database by the server.
but after adding grand totals, server is sending two queries to database and my report performance went down.
Please suggest how to avoid this.

Hi,
OBIEE wil always fire a seperate query for Grand total. This is expected behaviour. You should look at the other ways to improve the performance of report like putting some default filters so that OBIEE does not have to prform sum on huge data.

Difference between two queries for no client installed

I have created a collection for all discovered computers with no client installed using the following query:
select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.Client is null
If I go to Monitoring -> Client Status -> Client Activity and click on the link next to the pie chart for no clients installed I get a completely different result and they neither query contains the same computers as each other.
Anyone know what the exact query the link in the monitoring section is using and why the results between the two are completely different?
If would expect them to match up or at the very least that my first query should be the source of truth.

If I use:
select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.Client is null OR SMS_R_System.Client = 0
and use the same limiting collection as the built in monitoring query "All Desktop and Server Clients" I actually get 0 results from the query. If I use "All Systems" as the limiting collection I still only get the same results
that I do with out also querying for "equals 0" as well.
I read one article that said that "equals 0" actually shows you the clients had the CCM client but it was uninstalled where "is Null" returns systems that never had the CCM client.
I don't know if this is accurate but it doesn't explain why a built in monitoring query would return inaccurate results. It only returns a fraction of the non-client systems that the above query returns and as mentioned, the systems returned in one
are not included in the other.

Requirement wherein I want to call two queries in parallel using ABAP Prg

We are using RSCRM_BAPI to run a query in background and write the results to a table. We later read this table and create a file. I have a requirement u2013 wherein I want to call two queries in parallel using an ABAP program.
For our discussion assume:
1) Program : ZCALL_RCRMBAPI  is a program that calls RSCRM_BAPI in background and takes the query name as input
2) Program: ZMAIN_PROGRAM  this is the main program
The requirement is to call the ZCALL_RCRMBAPI in a loop. Also within the loop call it in parallel. Basically we have an ODS that stores ; FISCPER. So I call the two queries for a list of FISCPER.
ZMAIN_PROGRAM - A program that reads a table (ODS ) in our case and call the two programs in a loop and both should run in parallel .
Now if it was sequential u2013 it was easy u2013 I would just say
Loop at L_T_FISCPER .
Update Z_FISCPER with L_T_FISCPER-FISCPER u201C Assume Z_FISCPER is a Z table . The VARIABLE in the query Q1 and Q2 use a customer exit to read this table.
A)       SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q1 and return .
B)      SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q2 and return .
Endloop .
Question: How do I make these calls in parallel u2013 yet retain control in the main program?
A)       SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q1 and return .
B)      SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q2 and return .

Instead of RSCRM BAPI you can use the RRW3_QUERY_VIEW_DATA function module for greater control over program execution...

Listener - Two Services for Each Instance

Oracle 11r2g was installed on a Linux SO. Everything is working, but when I check the Listener Services I got this status:
lsnrctl services
Service "S060" has 1 instance(s).

There are Two Services for Each Instance. Is it normal or do I have to check anything else?
Thanks in advance.

Thanks in advance.Pretty normal. The "unknown" is the static registration coming from the SID_LIST entry in the listener.ora file. The "ready" is the dynamic registration from the db instance itself.

Merging queries for different multiproviders

Is there are a way to use the output of one query as an input parameter for another query and use the output from the second query in the report.
My requirement is that the data which is to be displayed in the report is found in two different multiproviders and we cannot create any other multiprovider. I created two queries for the two multiproviders. One of the characteristic of the first query has to be an input parameter for the second query and the one of the Key figure output of the second query should be one of the column in the report. Can anyone please suggest a way for this?

Hi,
this is possible by taking a variable restriction on that characterstic in the second report. This variable should have a processing type equal to REPLACEMENTPATH and there you can specify the first query as the source for this variable.

Whats the difference between these two queries ? - for tuning purpose

Whats the difference between these two queries ?
I have huge amount of data for each table. its takeing such a long time (>5-6hrs).
here whice one is fast / do we have any other option there apart from listed here....
QUERY 1:
SELECT --<< USING INDEX >>
      field1, field2, field3, sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end)
    FROM
      tab1 inner join tab2 on condition1 inner join tab3 on condition2 inner join tab4 on conditon3
    WHERE
     condition4..10 and
    GROUP BY
      field1, field2,field3
    HAVING
      sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end) <> 0;
QUERY 2:
   SELECT --<< USING INDEX >>
      field1, field2, field3, sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0))
    FROM
      tab1, tab2, tab3, tab4
    WHERE
     condition1 and
     condition2 and
     condition3 and
     condition4..10
    GROUP BY
      field1, field2,field3
    HAVING
      sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0)) <> 0;
[pre]

My feeling here is that simply changing join syntax and case vs decode issues is not going to give any significant improvement in performance, and as Tubby points out, there is not a lot to go on. I think you are going to have to investigate things along the line of parallel query and index vs full table scans as well any number of performance tuning methods before you will see any significant gains. I would start with the Performance Manual as a start and then follow that up with the hard yards of query plans and stats.
Alternatively, you could just set the gofast parameter to TRUE and everything will be all right.

Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database"

Hi, Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database" ?
When I use Connect Object Explorer, the "Connect to Server" dialog box which pops up has only 4 selections in the Server Type Drop Down List. They are Database Engine, Analysis Services, Reporting Services & Integration Services. I have read
somewhere that there should be a compact database option. but I do not see it.
What I would like to do is use free form SQL Queries against the tables in "SQL Server Compact 4.0 Local Database" .
Once I have validated these queries, then I will use them in my Visual Studio 2012 C#, ASP.NET application. I created the Local Database using Visual Studio 2012 for use by my application.
Thank you for your help..

Hello,
With SSMS 2005 we have had the Option to work with SQL CE database files, but not with higher Version of SSMS.
You can use the free SQL CE Toolbax instead; see

Can I use same result set for two queries?

Hi,
Can I use the same result set for two queries?
For example:
ResultSet rs = null;
rs = ps.executeQuery(query1);
while (rs.next()) {
rs = ps.executeQuery(query2);
while (rs.next()) {
Is it OK to use? or Is there any preformance issues?
Appreciate your help.
Thanks in advance.
Prasad Vagolu

Sure. You have a variable of ResultSet type. First you create a ResultSet and assign it to that variable. Then later you create another ResultSet and assign it to that same variable. Assigning an object reference to a variable takes essentially no time, and at any rate it isn't any faster to assign it to a different variable. Also, no matter whether you use one variable or two, you are still creating two ResultSets.
However, you really should be closing your ResultSets after you finish using them. That's nothing to do with the assigning-to-a-variable question.

Plan hash value for two queries!

Hi,
DB : Oracle 11g (11.2.0.3.0)
OS: RHEL 5
I have two question:
1. Can two queries have same plan hash value? I mean I have below two queries:
SELECT /+ NO_MERGE */ MIN(payor.next_review_date)*
* FROM payor*
* WHERE payor.review_complete = 0*
* AND payor.closing_date IS NULL*
* AND payor.patient_key = 10;*
and
SELECT MIN(payor.next_review_date)
* FROM payor*
* WHERE payor.review_complete = 0*
* AND payor.closing_date IS NULL*
* AND payor.patient_key = 10;*
When I tried to review the execution plan for both queries, the plan hash value remain same. Does it mean that execution plan for both queries are same? If yes, then how Oracle understands or changes the execution plan based on hint. If no then what plan hash value represents?
2. If the execution plan with hint and without hint is same except for a given query except no.of rows and bytes. Does it mean that query with less rows and bytes scanned is better?
Thanks in advance

Hi,
there are two different things. One is EXPLAIN PLAN, which is how the optimizer thinks the query will be executed. It contains some estimates of cost, cardinalities etc. There is also EXECUTION PLAN. It also contains all this information regarding the optimizer estimates, but on the top of that, it also contains information about actual I/O incurred, actual cardinalities, actual timings etc.
So if a hint is changing optimizer estimates, but the plan stays the same, then impact on query's performance is zero.
If the actual numbers are changing, this is probably also irrelevant to the hint (e.g. you can have less physical reads because more blocks are found in the buffer cache the second time you're running the query, or you less work because you don't have to parse the statement etc.).
Actually, most of optimizer hints don't affect optimizer estimates; rather, they try to get the optimizer to use a certain access method or a certain join order etc. regardless of the cost. So you must be talking about such hints as cardinality, dynamic_sampling etc. If that's not the case -- please clarify, because this means that something wrong is going on here (e.g. an INDEX hint may work or it may fail to work, but if it fails, optimizer estimates shouldn't change).

DNS timeout and Name Server timeout between two DC's

Hi All
My clients have a brand new domain built for them, with two domain controllers at separate sites, and one site is having some issues.
At one site (where DC2 is hosted), all users are having 5-10 minute log on delays - once in everything is running without issues. Site where DC1 is has zero issues - they run smoothly, get a nice quick login etc. All users are using redirected folders and
all have the same GPO's applying to them.
DC1 also has periodic issues communicating with DC2 - nslookup using DC2 gives "DNS request timed out. timeout was 2 seconds" on external AND internal queries, but then 5 minutes later will resolve perfectly. During the "DNS time out"
period, trying to resolve DC2 as a Name Server also gives the error "A timeout occurred during validation".
Not sure if these (slow logon and DNS/NameServer time out issues) issues are related but I am at a loss.
Reverse lookup zones are fully created and populated, entries aren't randomly deleting themselves. Replication between both DC's is working fine, no errors and SYSVOL/NETLOGON are sharing fine from both DC's. Occassionally restarting the DNS server services
on both servers will kick them back into talking - but only for around 30sec-1minute, after that they communicate periodically without problems and spend the rest of the time not resolving.
Any ideas floating around, as I am at a loss here. We haven't been able to join more than a few test users to DC2's site for fear of them all calling every day due to long log on periods.

Hi,
Are you pointing each DC/DNS to the other one as primary dns in tcp/ip properties? Can you post a dcdiag /a /f:dcdiag.log from the DC2?
Any warnings/errors in Application log on the client(s) facing issues after they get logged in ? Can you also confirm that users from site with DC2 are having DC at : set | find /I "LOGONSERVER" output?
Hope it helps.
Regards,
Calin
Hi Calin
The DC's were originally pointing at each other for the primary but others prior to posting here suggested that was not best practice anymore and said they should be the other way around - in any case, either direction doesn't resolve the issues.
The only application error the users are getting is :
The winlogon notification subscriber <SessionEnv> was unavailable to handle a notification event.
The winlogon notification subscriber <GPClient> took 84 second(s) to handle the notification event (Logon)

The users are logging onto NDC1 currently as I did switch around their DNS servers to have DC1 as their primary to test if this resolved the logon times. It didn't so I've switched them back and will re-run the check to see which server is the logonserver.

Why are two queries better than one

I'm trying to help out our developers who are struggling with the performance of a very simple select statmenent that for some reason is exhibiting some very inexplicable results.
I'll show the SQL as a single statement first.....
select * from transaction1 t where t.hid in (select distinct h.hid from history1 h,filter1 f where h.fid = f.fid and f.match='value');
transaction 1 has 250k records, history1 has about 100k as does filter1. We know generally the subselect will only return a total of half a dozen or less records (only 1 in our testing here).
Running the above query takes around 7 seconds.
Changing this to a with clause.....
WITH a as (select distinct h.hid from history1 h,filter1 f where h.fid = f.fid and f.match='value') select * from transaction1 t where t,hid in (select a.hid from a);
and the runtime drops to 3 seconds. But then re-running the first statement again also now takes 3 seconds (so I guess there's some caching going on there).
Now what really puzzles is if we split this into two queries.....
select distinct h.hid from history1 h,filter1 f where h.fid = f.fid and f.match='value';
This takes .1 of a second,
select * from transaction1 t where t.hid in (12345);
And this takes .1 of a second.
So why when run seperately are they so fast, yet combined they take so long. I'm a bit baffled by this. We've rewritten the same SQL in half a dozen different ways with the same result and also done the same thing with other tables as well. Is it an optimisation issue?

Appologies for not following protocol, my first time posting on here.

We don't have privaleges to run trace, so I'm a bit stuffed there as I'm on the clients site, however I will get my developers to try this on our local server.

I have noticied that there are two entries for each archive log. Why this is so...?Mseberg already mentioned.. little in detail as below
Check for the name column in v$archived_log,
One location refers to Local destination LOG_ARCHIVE_DEST_1
Other location refers to your standby/DR location, But it will shows you only service name instead of full archive name.
select dest_id,name from v$archived_log where name is not null and completion_time like '%24%FEB%'
   DEST_ID NAME
         1 +ORAARCHIVE/prod1/archivelogs/arch_0001_0671689302_0000240097.arc
         2 (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=sldb1srv)(POR
           T=9101)))(CONNECT_DATA=(SERVICE_NAME=prod_sldb1srv_XPT)(INSTANCE_N

SQL queries for finding values in 4 different tables

I need to have certain queries to find specific data in this table, this is just an example table, but I will use the same ideas for my actual website and database.
customers (customerID: integer, fName: string, lName: string)
items (itemID: integer, description: string, price: float)
orders (orderID: integer, itemID: integer, aID: integer, customerID: integer, date: date)
addresses (aID: integer, housenum: integer, streetName: string, town:string, state: string, zip:integer)
Values I need to find are
List the town, first name, and last name of any customer who has shipped an item to the same town as another customer.
Return the average amount of money each customer spent in March of 2013. (Note that the answer will be a single number
List the first and last names of all customers who have had the same item shipped to at least two different addresses.
List the top two states that have generated the most total revenue and the revenue they generated
I did try a few different queries, for #3 I tried
SELECT customers.fName,
customers.lName,
COUNT(orders.itemID) AS `total items with diff address >= 2`
FROM customers
JOIN (SELECT customerID,itemID,
COUNT(DISTINCT aID) AS diff_address
FROM orders
GROUP BY orders.itemID
HAVING diff_address >= 2
) AS orders
ON orders.customerID = customers.customerID
but I only got 1 result, and I do not think thats correct.
Thanks for the help and I appreciate you taking the time to help me

Why not post the sample data + desired result? Always state what version you are using.
SELECT lname,A.aID,COUNT(*) cnt FROM customers C JOIN orders O ON c.Customerid=O.Customerid
JOIN address A ON A.aID=O.aID
GROUP BY lname,aID
Sorry cannot test it right now...

Queries for Open Sales Order Lines and Open Purchase Order Lines

Experts,
Forgive me if these have been addressed elsewhere but I can't find them. I'd like to create two queries to use as Alerts as follows:
1. Query of open lines in Sales Orders that are more than two weeks old
2. Query of open lines in Purchase Orders that are more than 2 days old
Thanks in advance for your help.
Steve

Hi Steve,
A couple of query templates you can use for your alerts are as follows:
Purchase Orders
SELECT T0.\[DocNum\], T0.\[DocDate\], T0.\[DocDueDate\], T0.\[CardCode\], T0.\[CardName\], T1.\[ItemCode\], T1.\[Dscription\], T1.\[Quantity\], T1.\[OpenQty\], T1.\[Price\] FROM OPOR T0 INNER JOIN POR1 T1 ON T0.DocEntry = T1.DocEntry WHERE T0.\[DocDueDate\] < (getdate() -2) AND T1.\[LineStatus\] = 'O'
Sales Orders
SELECT T0.\[DocNum\], T0.\[DocDate\], T0.\[DocDueDate\], T0.\[CardCode\], T0.\[CardName\], T1.\[ItemCode\], T1.\[Dscription\], T1.\[Quantity\], T1.\[OpenQty\], T1.\[Price\] FROM ORDR T0 INNER JOIN RDR1 T1 ON T0.DocEntry = T1.DocEntry WHERE T0.\[DocDueDate\] < (getdate() -14) AND T1.\[LineStatus\] = 'O'
You can change the SELECT section to remove some of the columns or add extra columns if need be. Once your happy with the query you can attach it to an alert and set the frequency.

Adrian
