Query Regarding Oracle Database Client

Hello,
I'm new to ORACLE and Intented to become Oracle Developer and DBA. I've question regarding Oracle Database Client software.
I know that there is Oracle Database server software but what is this Oracle Database Client. Is there any need to Install it on client machine as client mostly access the database use application software mainly develope in Java or C# etc. So, what is it need.
and one more question regarding SQL *Plus. Is it client process or server process as I learnent that it is client process and if it is. Is it can be part of Oracle Database Client. and can we seperately install the Oracle Database Client on machine on which DB server is aslo Installed.
Looking for reply.
Regards,
Danish Kamran

Certainly you are not mentioning the Oracle version, it is very important. Whenever you post a question reference the oracle version. There is a disk known as the oracle Client (10gR1, 10gR2 and 11gR1), this disk contains all required software to setup a client environment. If you are working with clients such as Java or C# you must have either the jdcb client driver (Jjava) or the ODBC software to access the database, this is included in the Oracle client disk.
Instant Client
There are other options for the client, you can install the instant client, this option allows you to install only the drivers without the Oracle utilities, this is particular useful if you are deploying third party applications and you don't want to install the complete client disk.
SQLPlus
SQL*Plus is a client application that runs on the client side, when you open a session it requests an Oracle server process to be executed on the server side. Once the session has been successfully setup then you can issue SQL commands from the client side. You should be aware that even if you launch SQL*Plus from the server side you will be working with two processes, one for the client and the second one for the oracle server. This connection mode is also known as dedicated server, but you should be aware that there is another connection mode known as shared server, I won't explain it since it already goes off topic.

Query in timesten taking more time than query in oracle database

Hi,
Can anyone please explain me why query in timesten taking more time
than query in oracle database.
I am mentioning in detail what are my settings and what have I done
step by step.........
1.This is the table I created in Oracle datababase
(Oracle Database 10g Enterprise Edition Release 10.2.0.1.0)...
CREATE TABLE student (
id NUMBER(9) primary keY ,
first_name VARCHAR2(10),
last_name VARCHAR2(10)
2.THIS IS THE ANONYMOUS BLOCK I USE TO
POPULATE THE STUDENT TABLE(TOTAL 2599999 ROWS)...
declare
firstname varchar2(12);
lastname varchar2(12);
catt number(9);
begin
for cntr in 1..2599999 loop
firstname:=(cntr+8)||'f';
lastname:=(cntr+2)||'l';
if cntr like '%9999' then
dbms_output.put_line(cntr);
end if;
insert into student values(cntr,firstname, lastname);
end loop;
end;
3. MY DSN IS SET THE FOLLWING WAY..
DATA STORE PATH- G:\dipesh3repo\db
LOG DIRECTORY- G:\dipesh3repo\log
PERM DATA SIZE-1000
TEMP DATA SIZE-1000
MY TIMESTEN VERSION-
C:\Documents and Settings\dipesh>ttversion
TimesTen Release 7.0.3.0.0 (32 bit NT) (tt70_32:17000) 2007-09-19T16:04:16Z
Instance admin: dipesh
Instance home directory: G:\TimestTen\TT70_32
Daemon home directory: G:\TimestTen\TT70_32\srv\info
THEN I CONNECT TO THE TIMESTEN DATABASE
C:\Documents and Settings\dipesh> ttisql
command>connect "dsn=dipesh3;oraclepwd=tiger";
4. THEN I START THE AGENT
call ttCacheUidPwdSet('SCOTT','TIGER');
Command> CALL ttCacheStart();
5.THEN I CREATE THE READ ONLY CACHE GROUP AND LOAD IT
create readonly cache group rc_student autorefresh
interval 5 seconds from student
(id int not null primary key, first_name varchar2(10), last_name varchar2(10));
load cache group rc_student commit every 100 rows;
6.NOW I CAN ACCESS THE TABLES FROM TIMESTEN AND PERFORM THE QUERY
I SET THE TIMING..
command>TIMING 1;
consider this query now..
Command> select * from student where first_name='2155666f';
< 2155658, 2155666f, 2155660l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.668822 seconds.
another query-
Command> SELECT * FROM STUDENTS WHERE FIRST_NAME='2340009f';
2206: Table SCOTT.STUDENTS not found
Execution time (SQLPrepare) = 0.074964 seconds.
The command failed.
Command> SELECT * FROM STUDENT where first_name='2093434f';
< 2093426, 2093434f, 2093428l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.585897 seconds.
Command>
7.NOW I PERFORM THE SIMILAR QUERIES FROM SQLPLUS...
SQL> SELECT * FROM STUDENT WHERE FIRST_NAME='1498671f';
ID FIRST_NAME LAST_NAME
1498663 1498671f 1498665l
Elapsed: 00:00:00.15
Can anyone please explain me why query in timesten taking more time
that query in oracle database.

How to install Oracle Database Client 32-bit libraries.

Dear All,
In the document : http://download.oracle.com/docs/cd/E10415_01/doc/bi.1013/b31765.pdf
it is written "For 64-bit Linux system installations, you must use the Oracle Database Client 32-bit libraries"
how can i install just the libraries from OUI Database 11.2
Is it must to install these libraries first, whatif I install Oracle11.2 64bit client, and then install the OBIEE. Anyhow i need to install OracleDBClient to connect to Oracle server 11.2.

You can't "just install the libraries", you need a full ORacle client installation. The Oracle client can be installed after OBIEE but you must have an Oracle client to connect to an Oracle database via OCI (which is the recomended approach). 64bit client should be fine as long as it has the 32bits libraries. The 10g client does, not sure about the 11g client. Make sure you install the FULL Oracle client, not the Instant Client. The 32bits client libraries are located under lib32, the lib directory is for the 64bits ones. You might need ot re-link them if they were linked correctly during the client installation. But for more information post a message in the Oracle client forum, this is the OBIEE forum.

Doubt regarding Oracle Database 10g Release 2 (10.2.0.1.0) installation

hello
my pc has following configurtion
256mb ram
60gb hdd
p4 2.4 ghz
win xp pro sp2
I want to know if my pc will be able to run " Oracle Database 10g Release 2 (10.2.0.1.0) " standard edition on it.
<<http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winsoft.html>>
I thought of increasing RAM, but it is not feasible.
I know i could run oracle XE, but can my pc also run the standard edition.
I could not find minimum hardware requirements for standard edition on this site.
anyway, i will use it for sql and and other advanced concepts in RDBMS which i may learn during my course in database. so i prefer standard edition instead of XE
any help greatly appreciated
thanks in advance

I suggest you not to doubt regarding Oracle Database 10g Release 2 (10.2.0.1.0) installation.
It is not necessary. If you don't receive an answer within a reasonable amount of time you could edit your thread with whatever ( a period is enough) to raise it to the top once again.
It becomes difficult for us to track duplicated threads and unnecessarily duplicates efforts.

Oracle Database Client -- Oracle Database in SSL mode.

Experts,
I am trying to connect to a remote oracle database which in SSL mode. I installed "Oracle database client" on other server and trying to connect to remote database in SSL mode.
Can you please provide brief steps ?
Do I need configure any wallets on client side too ?. If yes, copying wallets from database server to client is enough ?
Please help me.
Thanks

PC session hangs when launch a query from Oracle 9i client to 10g database

I have a pc with Oracle 9.2.0.1.0 client installed. The database server level is 10.1.0.5.
When I launch a query from a client session the pc sesssion locks up and doesn't return any results. When I launch the same query from the database server , or from other pcs with Oracle client 10 installed , I get results almost immediately from the query.
The pc in question is running Windows XP Service pack 2. Other queries run fine from the pc.
Are there are any known issues with Oracle 9 clients querying an Oracle 10 database ?

Thank you for your reply. No, I must admit I didn't think of looking at the wait events. I will look at this as soon as I get a chance.
Thanks again for your suggestion.

Querying an Oracle Database Using XSL

I know from years of experience as an Oracle DBA that to suggest that a program generate SQL is anathema, but I'm going to ask anyway!
Is there currently (or soon) to be a means of submitting XSL (or, perhaps, some variant based on the most recently published "standard") to an Oracle database and receiving an XML result set?
Note that I have not mentioned writing any SQL myself. I'm either looking for some middleware to translate the XSL "query" into the appropriate SQL query (with appropriate after-query transformations) or for the database engine itself to be able to parse and optimize XSL.
I just read a position paper (dated 1998) on this site that says that Oracle intends to closely follow developments in the world of XML Query. And, I've read in a "Byte" article ("Where Are The XML Apps We Can See And Touch? Report From XML DevCon 2001", April 2001, Jon Udell) that Steve Muench had demonstrated some means of super-imposing an XML schema over top of a database in order to query it via XPath. Where does the product stand in regards to this type of functionality?
Thanks in advance,

http://technet.oracle.com/tech/xml/xdk_java
- The XSU can transform data retreived from object-relational database tables or views into XML.
- The XSU can extract data from a XML document and using a canonical mapping, insert the data into the appropriate columns/attributes of a table or a view.
- The XSU can extract data from a XML document and apply this data to updating or deleteing values of the appropriate columns/attributes.

Store SQL Query in Oracle database

Hello,
I am storing SQL query in database. here is an example of query.
INSERT INTO TABLE_1 Values (' " + getValue1() + " ', ' " + getValue2() + " ' )
getValue1() and getValue2() are functions to retrieve values.
When I read query from the database and execute it, it doesn't read values from function.
After I read query from database I would expect it to be
INSERT INTO TABLE_1 Values ('value1', ' value2' ) but it is not reading values and trying to execute whatever I got from database.
Any help?
Thanks

Thanks for your reply. Let me give you more info.
All I am trying to do is storing queries in oracle
database to use it in future for reporting. As I am
doing reporting where clause will be different every
time. Reporting involves queries not updates. But in any case that means that you would use a java SQL string that is useable via a prepared statement. As such your statement would look like....
INSERT INTO TABLE_1 Values (?,?)
Is it not possible to substitute variable string I
got from database?What do you mean?
SQL is SQL. You construct SQL so it is valid and runs. Can you construct SQL so it runs a function/select and uses that value in some more SQL - depends on the database, but usually.
But that has nothing to do with java - it is SQL.
Query contains variables that I have in Java code .Then it is SQL. It is java. You use bind variables (see PreparedStatement) and assign values to it.
The SQL for such a query would look like the following...
select field1, field2 from table1 where id=?
In your java you would then use something like PreparedStatement.setInt(1, 100), to fill in the value for the '?' in the above.
You might also note that your solution will not work for any arbritrary SQL statement unless you are also storing meta data about the SQL itself. For instance the following SQL statements would return the same result set but your java code would have to populate the bind variables different for both...
select field1, field2 from table1 where id=? and name=?
select field1, field2 from table1 where name=? and id=?

Installing an Oracle Database client on Application Server

Hi all
I have posted before but thought I'd clean up my original question and repost - apologies but I'm desperate for help here.
I have a problem using Oracle Wallet with Application Server and Developer Suite 10g Rel 2 Software Update 10.1.2.3.0 on Windows 2003. The problem arises because the database which ships with this version of Application Server is 10.1.0.5. This database version is not compatible with Oracle Wallet external passwords eg sqlplus /@MY_WALLET_NAME.
So...to get around this I'm looking at putting the 10.2 database client on which will allow me to use sqlplus with the wallet.
My questions is:
Does anyone have any advice for retaining existing Application Server functionality (we use Discoverer, Forms and Reports (RWCLIENT)) with a new Oracle 10.2 home on the server?
I will put on the client so would expect if I copy across the tnsnames & sqlnet ora, the connectivity is all backward compatible. SQL*Plus is obviously backward compatible. I'm not familiar with Application Server so am looking for guidance on any configurations I might need to change to make sure they pick up the right Oracle Home. For example, with the new Oracle Home at the start of the %PATH%, will RWCLIENT work as normal?
Thanks,
Tom

Any use of the Oracle Database Express Edition is subject to the following limitations;
1. Express Edition is limited to a single instance on any server;
2. Express Edition may be installed on a multiple CPU server, but may only be executed on one processor in any server;
3. Express Edition may only be used to support up to 4GB of user data (not including Express Edition system data);
4. Express Edition may use up to 1 GB RAM of available memory.
That was the limitation from Oracle Corporation

Problem querying an Oracle Database using PHP

Hi there, im rather new to Oracle so pardon my ignorance if this is completely obvious but I am creating a web form that queries an oracle database, firstly is a user form which looks like this.
 
Search for Investments 
<form action="query.php" method="POST"> 
<input type = "text" name = "invest"> 
<input type="submit" value="Search" name="submit" /> 
</form> 
----------------------- 
and the php script which looks like this 
----------------------- 
<?php <
print "<HTML><PRE>"; 
require_once('connect.php'); 
select_data($conn); 
$invest = $_POST['invest']; 
echo "Returning results related to $invest"; 
function select_data($conn) 
{ $stmt = ociparse($conn,"select * from investmentbase where INVTYPE='$invest'"); 
ociexecute($stmt,OCI_DEFAULT); 
echo "<table border = 1 class=results>"; 
echo "<tr>"; 
echo "<td>Reference Number</td>"; 
echo "<td>User ID</td>"; 
echo "<td>Investment Type</td>"; 
echo "<td>Investment Description</td>"; 
echo "<td>Amount Required</td>"; 
echo "<td>Due Date<td>"; 
echo "</tr>"; 
while (ocifetch($stmt)){ 
echo "<tr>"; 
echo "<td>"; 
echo ociresult($stmt,"INVREF")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"USERID")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"INVTYPE")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"INVDESCRIPTION")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"AMOUNTREQUIRED")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"REQUIREDATE"); 
echo "</td>"; 
echo "</tr>"; 
} 
echo "</table>"; 
} 
ocilogoff($conn); 
print "</PRE></HTML>"; 
?> 
When i search for a value that is in the database no results are returned, however the form is definitely posting the variable as the echo statement on the PHP script displays it. Any ideas would be gratefully appreciated
Many Thanks
Paul

Do you need to set $invest before calling do_select() and pass it as a
parameter? Also, watch out for SQL Injection security risks. Try
using a bind variable.
$invest = $_POST['invest'];
echo "Returning results related to $invest";
select_data($conn, $invest);
function select_data($conn, $invest)
$stmt = ociparse($conn,"select * from investmentbase where INVTYPE=:ibv");
ocibindbyname($stmt, ':ibv', $invest);
ociexecute($stmt,OCI_DEFAULT);
. . .Although the PHP 4 naming style for oci8 functions can be used with
PHP 5, I know there is a possibility you are using the PHP 4 OCI8
extension. If you are, then upgrade at least OCI8. There are some
notes on this in

Query regarding oracle functions

Hi All,
I ahve been trying to work with decode and NVL to get the following output:
Value     Output
NULL     1

2     2
3     3
for this i have written the below query:
SELECT DECODE(NVL(high_value,1),0,1,NVL(high_value,1)) from tab1;
Can there be any alternate to this using other functions?

How to execute remote query by Oracle Database Link

I use Oracle Database Link to query data from SQL Server. The query is like:
select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*
tableA and tableB is large and the result is relatively small. This query executes quickly in SQL Server since indexes are built both on the two tables. But it is very slow on Oracle Database Link to SQL Server.
I guess the join operation is performed on Oracle side not on SQL Server side, thus the indexes are not used. Since I just need the joined result, I prefer to perform the query entirely on SQL Server and get the small result only. But I have no privilege to create views on SQL Sevrer.
I konw that using SQL Server's linked server and OPENQUERY function can achieve this goal. I wonder how to do this on Oracle Database Link. Thanks!

DO NOT DO THIS....specifically:
"select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*"
You would be better off to do the following:
create a Materialized View in Oracle and once/day (or as frequently as you feel necessary) pull the data from SQLServer and then do the join locally by creating MV as TABLEA_MV and TABLEB_MV and then have views that have the REALTABLEA and REALTABLEB names that point to these MVs. This can be done without recompiling or changing your code. Trust me, I have seen this sort of thing in the past that completely crippled an IBM mainframe using DB2 along with a major network segment by having this sort of join via DB links. You must understand the ramifications of your "design" and I can tell you for certain that it is a very BAD!!! idea... Fix this before you are issuing another command: "alter DBA update resume/CV;"
The app went into production at 7AM. By 9:30AM, the mainframe had executed more than 10Billion I/O's. It took > 15hrs for the mainframe to recover once we shutdown the app and implemented the view/MV described above.
I will leave it as an excercise for the OP to develop the syntax for this.
