Adaptive Cursor Sharing and OLTP databases

Hi all,
I am reading a book about performance that affirms that, for OLTP environments, it is recommended to disable the Adaptive Cursor Sharing feature (setting the hidden parameter OPTIMIZEREXTENDED_CURSOR_SHARING_REL to NONE and the CURSOR_SHARING to EXACT). The book recommends this to avoid the overhead related to the feature.
I know that with this feature you can avoid the Bind Peeking issue as it creates more than one execution plan for the same query. So, it is really a good practice to disable it?
Thanks in advance.

OK, thanks for pointing out.
Getting back to your original question:
So, it is really a good practice to disable it?No, it is not, especially not without approval of Oracle Support.
Furthermore, I feel confirmed by that point from the book review by Charles Hooper as well as his additional points:
The book states that in an OLTP type database, “we probably want to disable the Adaptive Cursor Sharing feature to eliminate the related overhead.” The book then suggests changing the CURSOR_SHARING parameter to a value of EXACT, and the OPTIMIZEREXTENDED_CURSOR_SHARING_REL parameter to a value of NONE. First, the book should not suggest altering a hidden parameter without mentioning that hidden parameters should only be changed after consulting Oracle support. *Second, it is not the CURSOR_SHARING parameter that should be set to a value of EXACT, but the OPTIMIZERADAPTIVE_CURSOR_SHARING parameter that should be set to a value of FALSE (see Metalink (MOS) Doc ID 11657468.8). Third, the blanket statement that adaptive cursor sharing should be disabled in OLTP databases seems to be an incredibly silly suggestion for any Oracle Database version other than 11.1.0.6 (this version contained a bug that lead to an impressive number of child cursors due to repeated executions of a SQL statement with different bind variable values)*. (page 327)"

OLTP and OLAP databases on same SQL Server?

Would you put OLTP and OLAP databases on same SQL Server or separate?
I realize the ideal would be separate, but that means 2 expensive licenses instead of 1. Most of our OLTP stuff happens during the day while OLTP processing happens at night (so good use of resources) if just 1 server. Also, the disks that hold
the files could have different allocations (small chunks for the OLTP disks, large for the OLAP disks). Also, by being on the same database server, the OLTP data is immediately accessible for processing into the warehouse.
Or, is it just a cardinal rule to never mix the two worlds as server completely different purposes?
Thanks.

Answer given in simillar below thread would help you for sure:

Please reply:how to avoid extra trailing spaces while using cursor sharing

i am using cursor sharing with FORCE or SIMILAR.
what is the solution to avoid extra trailing spaces without any java code change.
do we have any option in oracle to avoid extra trailing spaces during the query processing ?
I am using Oracle 10g
CURSOR SHARING is a feature in which multiple sql statements
which are same will have a shared cursor (in the library cache) for an oracle session,
i.e, the first three steps of the sql processing (hard parse, soft parse, optimization)
will be done only the first time that kind of statement is executed.
There are two ways in which similar SQL statements with different condition values can be made to "SHARE" cursor during execution:
1. Writing SQLs with Bind Variables: SQLs having no hard coded literals in them
For e.g., the query below
SELECT node.emp_name AS configid
FROM emp node
WHERE emp_no = :1
AND dept_no =
DECODE (SUBSTR (:2, 1, 3),
:3, :4,
(SELECT MAX (dept_no)
FROM emp
WHERE emp_no = :5 AND dept_no <= :6)
AND node.dept_type = :7
ORDER BY node.emp_name
Here all the variables are dynamically bound during the execution. The ":X" represents BIND Variable and the actual values are bound to the SQL only at the 4th step of the execution of the SQL.
In applications: The queries written with "?" as bind variables will be converted into ":X" and are sqls with Bind Variables.
2. The CURSOR_SHARING parameter: Only Useful for SQL statements containing literals:
For eg., the query below:
SELECT node.emp_name AS configid
FROM emp node
WHERE emp_no = 'H200'
AND dept_no =
DECODE (SUBSTR (:1, 1, 3),
'PLN', :2,
(SELECT MAX (dept_no)
FROM emp
WHERE emp_no = :3 AND dept_no <= :4)
AND node.dept_type = :5
ORDER BY node.emp_name
In the query above, there are two hard coded literals H200 , PLN. In this case when the same SQL executed with different values like (H2003 , PLN), oracle will create a new cursor for this statement and all the first three steps ( hard & soft parse and optimization plan) needs to be done again.
This can be avoided by changing the CURSOR_SHARING parameter which can be set to any of three values:
1. EXACT: Causes the mechanism not be used, i.e. no cursor sharing for statements with different literals. This is the default value.
2. FORCE: Causes unconditional sharing of SQL statements that only differ in literals.
3. SIMILAR: Causes cursor sharing to take place when this is known not to have any impact on optimization.
So, FORCE and SIMILAR values of the parameter will be helping in cursor sharing and improve the performance of the SQLs having literals.
But here the problem arises if we use the FORCE and SIMILAR other than EXACT.
alter session set cursor_sharing ='EXACT'
select 1 from dual;
'1'
1
alter session set curson_sharing='FORCE'
select 2 from dual;
'2'
2
alter session set curson_sharing='SIMILAR'
select 3 from dual;
'3'
3
So, this will give extra trailing spaces in when we retrieve from java method and any
further java processing based on the hardcoded literal values will fail. this needs lot of
effort in remodifying the existing millions of lines of code.
My question is i have to use cursor sharing with FORCE or SIMILAR and can't we do the trimming
from the oracle query processing level ?
please help me on this ?

Sharing in Symetrics Array an Oracle datawerehouse and oracle database 9i

I
i want to know if someone have an sharing in Symetrics Array an Oracle
datawerehouse and oracle database 9i, or any array for high
availability. This because i have to do implement an installation
datawarehouse and db9i on the same arrary. Just know any comment if
whichever with share with me your expertise from any situation with
this, please.
Thanks

Thanks for the reply.
Actually I thought that the OCCI forum was for Object oriented OCI, so while I'm using C++, I'm not using the object oriented side of OCI, just using the normal OCI calls. Guess I should have been a little clearer in my original post.
But my main question really concerned the version of the client and the version of the database which you answered.
Thanks,

Shared and Dedicated Mode in Oracle 8i

Can any one describe what is basic difference when we install Oracle8i in dedicated and Shared modes. I have to create Oracle8i Database for not more 150 users. Actually less then 20 users might be accessing database but in future it can go up to maximum 100.

WIthout understanding your application and hardware in some detail, it is impossible to say which mode is better-- and that's without accounting for a mixed-mode setup where some connections are shared and some are dedicated.
If there are going to be 20 simultaneous connections, dedicated server is almost always preferred. If you start to get up to 100 simultaneous connections, depending on your hardware, it may become appropriate to use shared server. If you have a high-end multi-CPU machine, it will easily handle 100 connections. If you have a low-end single-processor Windows server, you might have problems with dedicated server.
OLTP systems tend to be more amenable to shared server than DSS systems, because sessions spend a lot of time idle in the former type of application.

Shared and Dedicated Server...

Dear All,
Can anybody tell what's the difference between shared and dedicated server? Our database is Oracle 9.0.1 in Windows 2003. Our total session is around 200. Our server is dedicated server. What will be the benefit if we change our database to shared server for specific users???
Shared pool size = 728MB
Buffer Cache = 592MB
Java pool = 104MB
Large pool = 60MB
There is no pga_aggregate_target in our database. Is the configuration ok for more than 200 users??? Most of the times we get 'out of process memory error'. What should we do in this situation??? Plz suggest.

mrashid07 wrote:
Can anybody tell what's the difference between shared and dedicated server?Dedicated server is the default. It means that each and every user session is serviced by a dedicated Oracle server process. 200 user connections? 200 dedicated server processes.
On Windows these are however threads inside the physical oracle.exe process (and not actual separate process images like on Unix/Linux for example). A standard thread on Windows needs around 2MB of kernel space. So 200 threads, for 200 dedicated server connections, need 200 x 2MB RAM.
Shared server works differently. A pool of dispatchers and shared servers are created. The dispatcher processes deals with the communication between the Oracle client and the Oracle instance. A dispatcher places client requests on a virtual circuit. These requests are picked up by idle shared server processes and processed. The results are send back to the client via a dispatcher process.
So instead of having 200 dedicated server processes to service 200 users, you can for example use 5 dispatcher processes and 30 shared server processes to service the 200 sessions of those 200 users. In this case 35 processes are used that translates into 35 threads at a basic 2MB RAM cost per thread. (also note that the UGA now moves from the Oracle PGA to the Oracle SGA and the SGA needs to be sized accordingly).
However, should such a user session send a long and complex request, that will tie up that shared server for a long time.. and this is bad. When the shared server process is busy, it cannot service any new requests. When all the shared servers in the pool are busy, no new request can be serviced. So you want the requests from the clients to be short and sweet - with a shared server not spending more than a few seconds per request.
So typically OLTP requests are fine for shared servers.. OLAP requests not.
Our database is Oracle 9.0.1 in Windows 2003. You should have been on 9.2.0.7 (last 9i patch set). You should currently being in the process of upgrading to 11gR2. 9i is basically an unsupported product. It is not a good idea to use an unsupported product in production. Even worse when you are not using the latest patchset for that product.
As for using Windows.. why? 32bit is old hat. 64bit CPUs are standard even in today's desktop PCs. Consider using Linux instead. It is Open Source, is free ito purchasing (you only pay for support and maintenance) and it has had de-facto 64bit support for many years now. There's no need to hack the operating system, like Windows with its AWE extensions to address more than 4GB RAM.

What is the difference between lap and oltp

HI experts, I want to know the difference between OLAP and OLTP and why OLTP cannot be used in bw instead of OLAP? Need realtime anwsers please!!!!!!!!!!

hi navin...
Online transactional processing (OLTP) is designed to efficiently process high volumes of transactions, instantly recording business events (such as a sales invoice payment) and reflecting changes as they occur.
Online analytical processing (OLAP) is designed for analysis and decision support, allowing exploration of often hidden relationships in large amounts of data by providing unlimited views of multiple relationships at any cross-section of defined business dimensions.
OLTP databases are typically input sources for data warehouses or data marts. The data warehouse in turn is the typical source of data for an OLAP database. The value in an OLAP database is that many complex calculations and predefined queries are preprocessed and results are stored and are available via an OLAP exploitation application allowing quick access to cross-sections of business data. Rapid access to the aggregate information across defined business dimensions allows quick navigation and understanding of relationships.
The challenge is to find a solution that will both supply the necessary functionality while addressing the technical considerations of your organization. Some other important considerations include choosing technologies that can leverage existing investments in both hardware and software, and are open and integrated so that your applications are adaptable. This ensures flexibility and agility to meet future business demands.
There are several different modeling techniques. Snowflake and star schemas are just two of many choices. Deciding the best approach for your situation will depend on several factors, most importantly understanding the business issue, the users and their information needs. There is a wealth of information available, including courses, texts and guidelines on this subject alone
OLAP systems organize data in a multidimensional model that is suitable for decision support. OLAP is the analytical counterpart of OLTP, or Online Transactional Processing. SAP's BW is an OLAP system

The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
Building the Data Warehouse, 2nd Edition by W. H. Inmon
With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

my friend shared a video with me on icloud photo sharing and then she deleted it from her camera roll, how do I save it???(very urgent)

DVDs are encoded into MPEG2, which iMovie cannot edit. So you need to convert the DVD back to something else. For highest quality, I recommend that you convert the DVD to Apple Intermediate Codec. There is a free tool called MPEG Streamclip that will do this. You will also need to install the Apple QuickTIme MPEG2 Playback Component.
Here are the details.
1) Download and install the Apple MPEG2 QuickTime Component ($20) - available online from Apple.
2) Download and install MPEG Streamclip from Squared 5 (free).
3) Start MPEG Streamclip
4) Insert your DVD into your Mac. If DVD Player or Front Row starts automatically quit those.
5) Open a Finder window. Navigate to your DVD to the Video_TS folder.
6) Drag the .VOB files from the Video_TS folder and drop then into MPEG Streamclip.
7) If MPEG Streamclip offers to fix timecode breaks, say yes.
8) Use FILE/EXPORT TO QUICKTIME to convert the files to Apple Intermediate Codec (or h.264 if you prefer)
9a) Optional: You can deinterlace your footage in this step, if you like
9b) optional: If you know the date and or time of the footage, name your file
clip-yyyy-mm-dd hh;mm;ss
(let mpeg streamclip provide the extension). This will provide metadata that iMovie will use to put the event in the right year and month.
9c) Optional: If you don't want to make one huge clip out of your DVD, you can make smaller clips by using MPEG Streamclip. Move the cursor to the "in" point of the clip, and press i. Move the cursor to the "Out" point of the clip, and press o. Then do steps 8 through 10 and repeat until you have done this for all clips you want.
10) Save the resulting file in a place where you can find it, like your Desktop.
11) Open iMovie.
12) In iMovie, choose FILE/IMPORT/From File and choose the file you saved in steps 8, 9, 10.
13) iMovie will generate thumbnails and you can edit.

Shared Services Configuration : Database type

Hi all,
i installed essbase and couldn't connect to sql to load the data into essbase( though it works fine with excel and text file)
after numerous pondering on the forums I could not find a solution to my probelm
why i could not connect to sql from essbase ?
I decided to retry the installation . I have come to a point within installation where i need to select
Shared Services Configuration : Database type
unfortunately oracle is not available here though I have installed oracle 11g on my machine and setup users to be used in the epm system ( version 11.1.2)
the only type available is the oracle jdbc driver .
Any suggestion as to how i can get oracle database type here ?
OR am i missing something prior to installation.

To connect to load data or metadata follow steps
1. Create a system DSN in the machine which is hosting Essbase Server.
2. Select Create Rule file.
3. Go To File and select Open SQL.
4. Select Application and Application
5. Select DSN and provide user credentials.
Hope this helps.
Database Type - Is the database Type which you want to use i.e. IBM DB2 / MS SQL Server / Oracle...
Hope this helps.

COMPLEX PARTITIONING between an EXCEL and a DATABASE (Datasource)

I want to make a complex partitioning between an excel and a Database.
*In the Excel File :
- I have the Data summarized at Month Level,
-Time sales is between 1993 UNTIL 1996.
*In the Database:
-I have my DB Source at Day Level .
-Time sales is between 1993 until NOW.
In the BMM:
-In my Database's SALES LOGICAL TABLE SOURCE Content:
I put in WHERE SECTION :
" CAST ( EXTRACT( YEAR FROM TRANSACCIONAL."".OLTP.ORDER_HEADER.ORDERED_DATE) AS INTEGER ) > 1996"
To constraint the data from 1996 until NOW.
-And I specify at the level content:
To SALES LOGICAL TABLE SOURCE EXCEL FILE: MONTH DAY LEVEL
To SALES LOGICAL TABLE SOURCE DB : DAY LEVEL
I want to make a COMPLEX PARTITIONING(Value-Based and Level-Based).
When I try to make the query:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 14023] None of the fact sources for Times.Calendar_year_cal_year_code are compatible with the detail filter []. (HY000)
SQL Issued: SELECT Times.Calendar_year_cal_year_code saw_0, Sales.Amount_sold saw_1 FROM "Sales BI DataMart" ORDER BY saw_0
Can any1 help me?
Thanks in advance..

Hi,
Actually value based partitioning works fine on the data sources which are stored on RDBMS. I haven't try it with a excel source. There is a detailed description in the link below.

What's the Difference Between OLAP and OLTP?

HI,
What's the difference between OLAP and OLTP ? and which one is Best?
-Arun.M.D

Hi,
The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
Building the Data Warehouse, 2nd Edition by W. H. Inmon
With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

Shared and Dedicated server modes

Hi,
We have been having some issues with connections and listeners. Please find here... Link [Post1|http://forums.oracle.com/forums/message.jspa?messageID=3665455] and Link [Post2|http://forums.oracle.com/forums/message.jspa?messageID=3677914].
Despite this help from this forum, I still face some problem configuring listener in both Shared and Dedicated server modes.
Pls find the below the problem...
Two listeners namely, LSNR1 and LSNR2 have been started.
listener.ora:
LSNR2 =
(DESCRIPTION_LIST =
 (DESCRIPTION =
 (ADDRESS = (PROTOCOL = TCP)(HOST = dbdev.website.org)(PORT = 1522))
 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
SID_LIST_LSNR2 =
(SID_LIST =
 (SID_DESC =
 (SID_NAME = TESTDB)
 (ORACLE_HOME = /u02/app/oracle)
LSNR1 =
(DESCRIPTION_LIST =
 (DESCRIPTION =
 (ADDRESS = (PROTOCOL = TCP)(HOST = dbdev.website.org)(PORT = 1521))
 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
SID_LIST_LSNR1 =
(SID_LIST =
 (SID_DESC =
 (SID_NAME = TESTDB)
 (ORACLE_HOME = /u02/app/oracle)
)LSNR1 works with both Shared and Dedicated configurations, whereas LSNR2 neither DEDICATED nor SHARED configurations...
Here is the TNS names entry at the client (for LSNR2)...
serv2=
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xxx.xxx)(PORT = 1522))
 (CONNECT_DATA =
 (SERVICE_NAME=DEDICATED)
)When I try to connect using this, it says
+ ORA-12514: TNS: Listener does not know of service requested in connect descriptor +
Pls help.
Thanks,
Aswin.

Aswin,
I didnt see the other posts but the error is fairly simple,
>
ORA-12514:
TNS:listener does not currently know of service requested in connect descriptor
Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action:
- Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name>
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.
>
So check what you are passing in the connection string.

Can oracle work in shared and dedicated mode at the same time?

Hi All,
can oracle work in shared and dedicated mode at the same time?
Thanks

A database can work only in one mode at a time.
If the database is started in Dedicated Mode then it can not run in the Shared Mode. If you need to run it in the Shared Mode, bring down the Database , change DISPATCHERS, SHARED_SERVER, SHARED_SERVER_SESSIONS parameters in initfile and bring up the database to run it in Dedicated Mode.
But there is one catch here, if you have started the database in Shared Server Mode even then you can make a Dedicated connection to server.
Thanks!
