Most of the time queries remain in suspended state in our production environment.

Not getting any solution.

Wait typeS : PAGEIOLATCH_SH,PAGELATCH_EX is when requested page is in buffer and some other process/request
is holding the lock in buffer.
SQL will manage it internally , Have you faced in performance issue if yes the need to check
1) Fragmentation of indexes. if fragmented the defrag it so that time of execution will less and will also reduce wait time.
2) Any missing indexes is there then create it
3) Update statistics status of tables.
4) Check if any table scan is there the create appropriate indexes on that...etc ....

Setup optimization - Changeover time queries

We are planning to use Setup Matrix based optimization in PPDS to schedule planned orders. Setup group and keys are maintained in routings and available in PDS. The setup matrix is maintained and updated in resources. In the optimizer run, system will read the changeover time (transition time) from the setup matrix. I have queries on this process:
Q1 - Will the change over time also be taken into account while calculating the actual planned order start time and end time? Or will the setup activity time will just be taken from PDS (which in turn comes from ECC routing?)
Q2 u2013 If the answer to above is a no, does it mean that for production execution, APO will provide only the correct order sequence and approximate order start and finish timings? (This would be somewhat a letdown if we can't get a feasible schedule with order start and end timings; something the production folks could aspire to.)
Q3 u2013 We also plan to allow out some manual adjustments in DS Planning Board. When we move the orders around by drag and drop, will the DS Board read the changeover time from the setup matrix?

1. If you have checked sequence dependent set up activity in PDS during planned order creation also time will be taken from matrix not from routing.
2. Change in order sequence in DS board manually will result into different set up times based on matrix defined.

Real time queries to know more about live project

Hi All,
I am new to XI, I have some doubts about real time xi project related activities.
1. Who will be responsible for preparing the minutes of meeting? (XI Developer/Team Lead/senior consultant etc)
2 In usual Dev->QA->Prod project cycle...
Where would the Configuration and Version Control come into picture?
Who is responsible for configuration process of the developed objects?
How the configuration process would be in real time XI project? Are we needed to use any external configuration/version control tools like VSS etc..?
3. I come across the terms like Legacy Systems, Third Party systems, SAP systems, Non-SAP systems, Web Systems.
In real time project, can you please answer with few names for each type of systems above I had mentioned? I know this depends on landscape of the project. But I would like to know how the names of these systems would be in real time.
Like .. for Legacy systems --> Mainframe/AS-400 etc (Pls correct me,if i am wrong).
These questions could be very basic questions for Experts. Please answer these questions.
Thanks in advance.

Hi,
1. Who will be responsible for preparing the minutes of meeting? (XI Developer/Team Lead/senior consultant etc)
In general , TL will prepare and rest of all seniors will approved/ signed if it is senior level meeting , Offcourse it depends upon the meeting .
2 In usual Dev->QA->Prod project cycle...
Where would the Configuration and Version Control come into picture?
Who is responsible for configuration process of the developed objects?
How the configuration process would be in real time XI project? Are we needed to use any external configuration/version control tools like VSS etc..?
Yes Configuration will be the developer or the senior for interface configuration / basis for SLD configuration
the respective will be the responsible
3. I come across the terms like Legacy Systems, Third Party systems, SAP systems, Non-SAP systems, Web Systems.
It depens upon the project ... dont ask like this type questions .. these are very confidential ...
I hope this is technical forum ..

Sequence at run time

hi
i want get a automatically generated primary key value in a query that s executing as dynamic, like
execute immediate v_query;
where v_query contains the actual query..
i tried sequence, but we cant use sequence values in the run time queries..
i just want to generate automatically primary key values at run time...
can u help me?

you want generate the priamry key when you insert data in into table.
your v_query does it insert data, if this is the case then you can use trigger as shown below;
1. first make one sequence
2. then make one trigger
CREATE OR REPLACE TRIGGER BRI_Trig
BEFORE INSERT
ON table 1
FOR EACH ROW
DECLARE
v_id NUMBER;
BEGIN
IF :NEW.col_id IS NULL THEN
SELECT seq_name.nextval INTO v_id FROM dual;
:NEW.col_id := v_id;
END IF;
END;

Time of execution of SQL statement

Hi,
I executed some DML statements and Select statements as user SYS for user U1. How can I find the time of execution of these statements?
Regards,
Mathew

You have a couple of options to time queries.
SET TIMING ON has already been mentioned. I'll add that spooling the session to a file helps keep those timings for later reference.
You can use DBMS_UTILITY.GET_TIME to get start and end times in microseconds for PL/SQL evaluation. DBMS_PROFILER will time lines of PL/SQL code as they execute. Trace/tkprof has also already been mentioned, although tkrpof times tend to vary a bit between reported and real times and don't take OS activity into account as much as the other timings do.

Real-Time Data Acquisition

WHAT IS REAL-TIME DATA ACQUISITION AND
WHAT ARE REAL TIME QUERIES AND
DEAMON UPDATE AND HOW DO WE EXTRACT AND LOAD DATA
Please Explain in detail.....

Hi,
Real-Time Data Acquisition BI 2004s
Real-time data acquisition supports tactical decision-making. It also supports operational reporting by allowing you to send data to the delta queue or PSA table in real-time.
You might be having complex reports in your BI System, which helps in making decisions on the basis of data of your transactional system. Sometimes (quarter closure, month end, year ending...) single change in the transactional data can change your decision, and its very important to consider each record of transactional data of the company at the same time in BI system as it gets updated in the transactional system.
Using new functionality of Real-time Data Acquisition (RDA) with the Net Weaver BI 2004s system we can now load transactional data into SAP BI system every single minute. If your business is demanding real-time data in SAP BI, you should start exploring RDA.
The source system for RDA could be SAP System or it could be any non-SAP system. SAP is providing most of the Standard Data Sources as real-time enabled.
The other alternative for RDA is Web Services, even though Web Services are referred for non-SAP systems, but for testing purpose here I am implementing Web Service (RFC) in SAP source system.
Eg will be a production line where business wants information regarding defective products in the real time so that production can be stopped before more defective goods are produced.
In the source system, the BI Service API has at least the version Plug-In-Basis 2005.1 or for 4.6C source systems Plug-In 2004.1 SP10.

Can I use the Mini as an NTP (Time) Server?

Hello!
I was wondering if I can use the Mac Mini as a NTP (Time) Server? If it does, what would I need to do?
Thank you in advance,

NTP Service Overview
What is NTP Service?
Network Time Protocol (NTP) is a network protocol used to synchronize the clocks of computers on your network to a time reference clock. NTP is used to ensure that all the computers on a network are reporting the same time.
Mac OS X Server can act not only as an NTP client, receiving authoritative time from
an Internet time server, but also as an authoritative time server for a network. Your local clients can query your server to set their clocks. It's advised that if you set your server to answer time queries, you should also set it to query an authoritative server on the Internet.
Managing NTP Service
The following help topics help you configure and enable NTP service.

Query runs forever when using selection on line item dim

we have a cube zcube which has po number as a line item dimension .
everymonth users run queries this cube using po number as selection
criterai and using a wild card search on this field . every time
queries have run fine . however , this month when we try to do so
the query runs forever and no results are returned . i also tried
listcubing with similar selection but it also did not return any results .
our production system has lot of data . i tried in test system it worked fine
i checked the cube for compression and indices in production , they look fine
can anyone think of anything that could have gone wrong ? also did rsrv tests ..
but all come green
we have not done any developments on this cube , however we have shifted to
a new hardware in the past month . can anyone think of any reasons ?
anything that can help me catch the issue ? all suggestions welcome

Not sure,
Are you saying that you need both the counts seperately? or a combined count?
how are you joining alpha and beta tables? what is the join condition?
you need to do something like this,
SELECT COUNT(CASE WHEN
                    (A.col1 = 'Pete' AND SUBSTR(A.col2,,1,12)=SUBSTR(B.col2,,1,13))
                 OR ( A.col1 != 'Pete' AND SUBSTR(A.col2,,1,15)=SUBSTR(B.col2,,1,15))
                THEN 1 ELSE 0
             END)
FROM alpha A, beta b
WHERE alpha.join_cloumn= beta.join_columnG.

What are the best solutions for data warehouse configuration in 10gR2

I need help on solutions to be provided to my Client for upgrading the data warehouse.
Current Configuration: Oracle database 9.2.0.8. This database contains the data warehouse and one more data mart on the same host.Sizes are respectively 6 Terabyte(retention policy of 3 years+current year) and 1 Terabyte. The ETL tool and BO Reporting tools are also hosted on the same host. This current configuration is really performing poor.
Client cannot go for a major architectural or configuration changes to its existing environment now due to some constraints.
However, they have agreed to separate out the databases on separate hosts from the ETL tools and BO objects. Also we are planning to upgrade the database to 10gR2 to attain stability, better performance and overcome current headaches.
We cannot upgrade the database to 11g as the BO is at a version 6.5 which isn't compatible with Oracle 11g. And Client cannot afford to upgrade anything else other than the database.
So, my role is very vital in providing a perfect solution towards better performance and take a successful migration of Oracle Database from one host to another (similar platform and OS) in addition to upgrade.
I have till now thought of the following:
Move the Oracle database and data mart to separate host.
The host will be the same platform, that is, HP Superdome with HP-UX 32-bit OS (we cannot change to 64-bit as ETL tool doesn't support)
Install new Oracle database 10g on the new host and move the data to it.
Exploring all new features of 10gR2 to help data warehouse, that is, SQL MODEL Clause introduction, Parallel processing, Partitioning, Data Pump, SPA to study pre and post migrations.
Also thinking of RAC to provide more better solution as our main motive is to show a tremendous performance enhancement.
I need all your help to prepare a good road map for my assignment. Please suggest.
Thanks,
Tapan

Standard edition tuning

Dear all,
We have 11gr2 rac standard edition installed on solaris 10. Using
statspack, we found that highly elapsed times queries are consuming
cpu .We idenitifed the queries. but , how to tune this queries ?.
In enterprise edition,we can use tuning advisors to do it, but how
to do the same in standard edition ?
Kai

Well,
again there is a point to think.
here my expireince
i dont know is the database eariler migrated from enterprise edition to standard edition or have license of enterprise edition.
when i start generating AWR report the output is with empty fields, then after my work around i found we need to change paraemters of mangement pack as tuning+
then i can able to generate AWR report. But there is no option to me ask is it enterprise edition license or standard edition license.. ;-)
I think still we can generate AWR or ADDM reports with standard edition even if is cost option..

Trying to understand PARALLEL content index

After browsing the oracle documentation i have the following understanding
When we use the "PARALLEL n" clause while creating an index, the index creation is done in parallel as said https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=HOWTO&id=1290549.1. This is not related in any way in improving performance of the query that uses that index. Right?
Local partitioned index (as discussed http://docs.oracle.com/cd/B28359_01/text.111/b28303/aoptim.htm#i1006756) needs the table to be partitioned if the search query is to perform better. Right?
Also specifying memory during create index helps during index creation. Does it help in making the search query using the CONTAINS clause perform better?

Correct
Local partitioned index (as discussed http://docs.oracle.com/cd/B28359_01/text.111/b28303/aoptim.htm#i1006756) needs the table to be partitioned if the search query is to perform better. Right?
Yes, most of the times queries do support "parallel queries"
Also specifying memory during create index helps during index creation. Does it help in making the search query using the CONTAINS clause perform better?
Yes you are correct. It doesn't help in queries, it only helps index creation.

Application Server - Slow

Hi,
We are facing a problem with my Oracle Application server interms of perfomance during peak hours. We are using Itanium processor with 2 CPU and 8g memory. To my surprise neither CPU nor memory is utilized even to 50% but all users are complaining for system poor perfomance.
OS= Windows 2003 EE Service pack 2 HP Server rx3600 Itanium proc 64bit.
Forms based Apps server.
We would like to know what % of memory/CPU is allocated to the Application server and if any furthe tuning we can do to improve perfomance.
Regards,

There can be many reasons, start with this checklist:
* network connection between the servers, and between the client and the app server
* queries execution time
* queries count on requests
* script execution time
* requests count on a page (for static and dynamic content)
1st:For network connection,ask the user's to ping on the server
eg:"ping -t server ip address"
check the response time..it should be between 1ms -60ms..i it is greater then this try to increase the bandwidth of the network.
have tuned your application server??
Regards

Pl/sql Procedure is Not Creating With the CLOB data Type

Hi,
I am Using Oracle 10g Express Edition Release2.... My Doubt is While creating a table With CLOB Data Type the table is created successfully,but while Creating a Procedure With the CLOB Data type i am getting an Error Message
2667/5 PL/SQL: Statement ignored
2667/24 PLS-00382: expression is of wrong type
then i tried With the Varchar2(30000) the Procedure is Created Successfully note i have not changed any thing in my code except the data type.
I am Just Confused ......Why the Procedure is not Created with CLOB Data type?
Please advice ...
Thank U
SHAN

hi,
Thanks for reply....Another Example
CREATE TABLE USER_MAS (USER_ID VARCHAR2 (20 Byte),MAIL_ID VARCHAR2 (255 Byte));
set serveroutput on
declare
atable varchar2(64) := 'USER_MAS';
acolumn varchar2(64) := 'MAIL_ID';
avalue varchar2(64) := 'NEWYORK' ;
dyn_sql clob;
begin
dyn_sql := 'update '||atable||' set '||acolumn||' = '''||avalue|| '''' ;
dbms_output.put_line(dyn_sql);
execute immediate dyn_sql;
end;
commit ;
Error at line 2
ORA-06550: line 9, column 23:
PLS-00382: expression is of wrong type
ORA-06550: line 9, column 5:
PL/SQL: Statement ignored
When i Changed the Data type to varchar2(64)
update USER_MAS set MAIL_ID = 'NEWYORK'
PL/SQL procedure successfully completed.
Commit complete.
I like to Know the Reason Why the Procedure is Not Created in Oracle 10g XE DB
Note :the Same Script i used in 11g DB the Procedure is Created Successfully....
Why you need use CLOB or VARCHAR2 in your temp_num variable as you sending parameters as number?
In the Procedure we are create some run time queries while executing the procedure. There are around 10 run time queries created.
The size of each query is more than 4000 characters . We then add all the queries using union all after each query to the clob variable as the normal varchar will not support.
Please Advice
Thank U

Database activity in SQL Server

Hi, I m trying to develop a query to get specific information like when the last time queries/transactions were executed against a database, other than by
particular login (Agent service). Is there any way to Develop a query to do this?. and also Return who the user was that last executed the transactions/queries?
I have something from Aaron Bertrand like the below link, But that won't filter the login\user level. Is it doable? Please advise. Thank you!
http://sqlblog.com/blogs/aaron_bertrand/archive/2008/05/06/when-was-my-database-table-last-accessed.aspx:

Hello,
You can schedule a SQL Server Profiler trace to run and capture the TSQL->SQL:BatchStarting, TSQL->SQL:BatchCompleted and Stored Procedures->RPC:Completed events and make sure you include NTUserName and LoginName columns.
The trace file can then be queried like explained on the following resource:
http://technet.microsoft.com/en-us/library/ms188425.aspx
Hope this helps.
