Slow query against seg$ - Oracle 10g

Hi,
Our AWR report shows the following slow query, 3 minutes per execution,
select file#, block# from seg$ where type# = 3 and ts# = :1
This query isn't from our application for sure. Does anyone know what backgroud jobs or processes may execute this query?
Thanks.

It looks like the type of thing the SMON would run to clear up temporary segments after a process has done a rebuild, move, drop or similar. One reason why it might be slow is if you have a very large number of objects in a given tablespace that is subject to a lot of drops, creates etc. (E.g. a tablespace holding a complicated composite partitioned object with lots of indexes that goes through a frequent cycle of add/drop partition).

Running Oracle 9i client code against an Oracle 10g install on PC

On Unix I am able to run Oracle 9i client code against an Oracle 10g install by setting ORACLE_HOME to the Oracle 10g install location and then creating a symbolic link (example: ln -fs libclntsh.so.10.1 libclntsh.so.9.0).
On PC (in particular XP SP2) I want to do something similar without using "junctions" or "junction points". Is there a way to set an environment variable or ini file to have my 9i client code point to the right libraries? I keep getting an error saying that my client code will not run due to "orasql9.dll" not being found. The "orasql10.dll" is installed on my machine.
Any assistance would be appreciated.

You might want to check metalink doc,
Client / Server / Interoperability Support Between Different Oracle Versions
Doc ID: Note:207303.1
Even your application built on 9i, doesn't mean it will not work with 10g database. From what I can see, running 9i executable under 10g installation to create mixed blood breed will do more harm than good. Not only it's not supported but also the outcome is unpredictable.

Sub-query problem on Oracle 10g

The following query works on Oracle 10.2.0.1.0 on windows,but doesn't work on Oracle 10.2.0.2.0 on Linux.
Error report: SQL Error: ORA-00904: "T"."AUDIT_USECS": invalid identifier 00904. 00000 - "%s: invalid identifier"
It works after i remove the sub-query. I found that if use fields of T in sub-query,then error occurs. Is it saying that sub-query can't access the fields in main query?
What's the problem?
Is there any grammar erros?If so,what's the right likes?
Thanks!

Slow first connection using Oracle 10g xe and Visual Studio 2008

{noformat}
Good day,
I'm slightly unaccustomed to using forums, so bear with me.
My initial connection to the Oracle database takes approximately 30 seconds. It seems to be waiting for a connection before timing out and trying another connection which works, as all subsequent connections work immediately. I'm unsure how other people's responses in forums can help me due to the plethora of configurations, so here's mine. My comprehension of the oracle world is still growing, you'll have to explain the terms you're using for me, Hoping you can help.
I'm using Visual Studio 2008, set to use 32 bit debug mode, on a Windows 7 Pro platform. Also using Oracle 10g Xe, and have installed the 32 bit version of ODAC 11.2 (11.2.0.1) to aid making a connection from Visual Studio to Oracle.
I have a database set up and a user with system admin rights. This is all local for a programming project and will never see the light of day outside of my personal machine.
I am using code to connect, not the GUI. I wish to code this project completely without the aid of the GUI. so my connection string within Visual Studio C# is (pw/id hidden)...
string xe = "Data Source=xe;User Id=xxxxx;Password=xxxxx;";
OracleConnection conn = new OracleConnection(xe);
My c:\devsuitehome\network\admin\sqlnet.ora file is this:
# sqlnet.ora Network Configuration File: C:\DevSuiteHome\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (LDAP, TNSNAMES, EZCONNECT, ONAMES, HOSTNAME)
And my c:\devsuitehome\network\admin\TNSNames.ora file is this:
tnsnames.ora Network Configuration File: C:\DevSuiteHome\network\admin\tnsnames.ora
Generated by Oracle configuration tools.
XE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = xe)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <machine name)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = PLSExtProc)
Just for good measure, my tnsping xe shows:
"Used paramter files:<br/>
c:\devsuitehome\network\admin\sqlnet.ora<br/><br/>
Used TNSNAMES adapter to resolve the alias<br/>
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))(CONNECT_DATA = (SERVICE_NAME = xe)))
OK (0 msec)"
So, how can I make that initial connection faster so I don't spend 15 years testing my application due to slow start-ups? :)
Thank you.
Kevin.

I have formatted my hard drive since my first post. I was running window 64 bit with a higher version of the ODAC and that proved to crash my machine with faulty error messages about memory. I have reverted to a previous version of the ODAC tools and everything works very smooth now. Still the connection time is consistently 20 seconds or longer on the first attempt.
Just a little more information.. I am currently taking a college course with 15 other students, as you can tell by the impersonal machine name, where programming using visual studio 2008, and Oracle 10g xe is expected. All of us are using a 64 bit environment and we all have difficulties cutting down the load time of making the first connection to Oracle. Some people are longer making the connection, but none are shorter.
One other note. After the first connection is made, taking 20 or more seconds, and is closed, all subsequent openings of the connection are instantaneous, for all of us.
If there is ANYTHING more I can get for you, please let me know. With my environment stable as it is, I will not need to format or change any information for the foreseeable future.
Here is the information you requested
1 The connection method I am using, I have chosen the manual connection for you, however the delay exists if the connection is made through the GUI as well.
Historically, I am getting slow connection speeds through adding the connection through the GUI or by a manual connection. Here is how I am doing it manually. I have the connection being created in 20 seconds, which is the best I can get.

I fought for weeks about the ODAC version 11.2.0.1 that you see in the previous post, and that would be a whole new thread. Suffice it to say I have a reliable environment to program in with this 10.2.0.1.0 version that I am running now, and the connection time has not changed, it is still minimum 20 seconds load time, sometimes up to 25.

Hi Gurus,
Can you tell me the command to clear the Recyclebin in Oracle 10g.
Thanks in advance
~Anup.

You want not to use Recyclebin, then you may try as follws
alter system set recyclebin = off scope = both; -- 10.20
alter system set _recyclebin = off scope = spfile; -- 10.01

Slow query performance in Oracle 10.2.0.3

Hi,
We have Oracle 10.2.0.3 installed on RHEL 5(64 bit).We have two queries out of which one is a query using select while other query is using a insert.First we executed insert query which inserts 10000 rows in a table and then select query on this table.This works fine in one thread.But when we do samething in 10 threads, at that time INSERT is fine but select is taking very long time for 10 threads.Any bug related to parallel execution of queries for SELECT in 10.2.0.3?Any suggestion??
Thanks in advance.
Regards,
RJ.

Justin,
We have a same queries for INSERT and Select in 10 manual sessions outof which select query is taking more time to execute.Please refer to WAITs given below.No there is no bottleneck as far as hardware is concerned because we tested it on different configuration of servers.

SQL slow after upgrading to Oracle Database 10g Enterprise Edition Release

Hi all:
We have recently upgraded our database from Oracle9i Enterprise Edition Release 9.2.0.6.0 to Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
After that we found that our some sql getting very slow
for example query with 9i showing result in 4 seconds while in 10g showing result in 28 seconds.

My computer slows down and hangs after installing oracle 10g

My computer just slows down after installing oracle 10g. I have a pentium 4 3ghz with 512 memory (32 mb used by graphics built in card). It slows down and hanged even if I agjusted the swap memory to 800 mb. I have two swap file/page file - in drive c and drive d. I even cannot shut it down because it takes maybe 30 minutes just to see the "shut-off/log-off" screen.

Before starting up Oracle, when you go to the task manager, how much RAM does it show actually free? 512 MB is pretty small to run Oracle in the first place-- Windows and Office can use a fair chunk of RAM themselves, depending on which Office apps you are running. You may also be suprised by the amount of RAM that a web browser, email client, and the various other apps that folks generally install can use.

SQL Developer 3.0 against Oracle 10g

Hi,
I have used SQL Developer in previous employments and prefer use it now (ie SQL Developer 3.0), but unsure if the mix will work.
I am on a Windows Server 2003 Std 64bit Edition and with Service Pack 2. and have Oracle client 10g home with basic tools against an Oracle 10G database server.
So before installing, I would like some tips on the best mix for Client and Server with respect to SQL Developer.
I also understnad that it will require Java JDK install prior to SQL Developer. Will this require me to take into consideration current Java installs under
"C:\Program Files (x86)\Java\jre6\bin" and dated back to 30 Sept 2010
Many thanks before hand
Chris

You can can download SQL Developer with a JDK included. This is 32-bit, but will run fine in a 64-bit OS.
Alternatively you can download the 64-bit version of SQL Developer. This requires you to have a 64-bit JDK.
You can install multiple JDKs without interfering with each other. Your existing JRE installation won't work anyway as you need a JDK.
If you download a JDK, don't get Java 7 as SQL Developer doesn't work properly with that. Get the latest version of Java 6.

SQL SSRS 2008 DateTime Calendar Control and Oracle 10g Data Source

Hello. I am creating reports in SSRS 2008 using the calendar control for a date range. Let's say we select a start date of 3/3/2012. This parameter is sent into my SQL statement in the WHERE clause which is executed against an Oracle 10g database. All syntax has to be in SQL that Oracle understands, so no CONVERT or CAST.
The format of the date is throwing an error "ORA-01843: not a valid month" when I try to use the following:
SELECT *
FROM TABLE
WHERE STARTDATE >= TO_DATE('3/03/2012', 'MM/DD/YYYY')
I get ORA-01722: invalid number when I try the following:
SELECT *
FROM TABLE
WHERE STARTDATE >= >= TO_CHAR('3/03/2012', 'MM/DD/YYYY')
I cannot find a way to format the date parameter in SQL Server SSRS before it gets to the SQL to be executed in Oracle.
Please help.
Thanks,
Sunny

sb92075: I am showing you how Oracle renders the date if I do a simple select from the table from which I am trying to pull data. You are right, it sure doesn't prove anything other than how the date looks right out of the Oracle database, but hopefully, it will give a clue as to how I need my SSRS date parameter to work.

It works. The problem is getting the parameter '3/3/2012' into a usable format for Oracle.
Let's assume an application is sending in '3/3/2012' which will be used in an Oracle query (no PL/SQL allowed, nor can I create functions, stored procedures, etc - only straight up SQL). How can I prepare the parameter to successfully do the compare on the Oracle Date field?

Oracle 10g OLAP option

Hi all
Do we support creating a universe against an Oracle 10g OLAP database and how do we do this to report against OLAP data?
I notice that there isn't an OLAP universe option for this, so I presume that if we can then we do this via OLAP SQL expressions?
Thank you for your help and kind regards,
Deam

Hi,
You are right, we are supporting Oracle OLAP 10g using SQL.
In fact we provide an option in Universe Designer where you can automatically create an Oracle view based on an AW (Analytical Workspace) and then generate the universe:<ul><li>Select "Metadata exchange" menu option from "File" menu
<li>Then select "Oracle OLAP 9i/10G/11g" option
</ul>You can therefore customize the universe by adding objects, filters, measures, etc.
You can also add other tables in the scema in order to provide drill-though capabilities.
Regards,
Didier

Error in Cursors in Oracle 10g

We have a VB program that is running a procedure with a cursor like this:
cursor cleo is select * from tabla1 where campo1='valor1';
leer cleo%rowtype;
begin
open cleo;
loop
fetch cleo into leer;
exit when cleo%notfound;
end loop;
close cleo;
end
Then return rows that not are part of the set given by the select statement.
The problem is given randomly when running the VB program, instead if run the same statement in sqlplus it works fine.
The program works fine against an Oracle 8 database, the error appears against an Oracle 10g database
null

the code to execute is:
create or replace procedure cpc_jz_aux (dirname varchar2, plan varchar2, error out varchar2) is
file_write sys.utl_file.file_type;
cursor cleo is select *
from oper.plan_hidro_et_per_cpcs
where id_plan = plan
and id_etapa = 1 order by id_hidro,id_per;
leer cleo%rowtype;
BEGIN
error:=NULL;
if sys.utl_file.is_open(file_write) then
sys.utl_file.fclose(file_write);
end if;
file_write := sys.utl_file.fopen(dirname,'cpc_jt3.dat','w');
     open cleo;
     loop
          fetch cleo into leer;
          exit when cleo%notfound;
          sys.utl_file.put_line(file_write,leer.id_hidro||','||leer.id_per||','||

                    ','||nvl(leer.zmax,0));
     end loop;
     close cleo;
     sys.utl_file.fclose(file_write);
exception
when others then
dbms_output.put_line('error:'||sqlcode||' '||sqlerrm);
error := sqlerrm;
if sys.utl_file.is_open(file_write) then

Oracle 10g(10.1.0.4) , BusIntelligence 10g(10.1.2), ApSrv 10g(10.1.2)

I have all ready successfully installed Oracle 10g Database 10.1.0.4 with appropriate olap patch.
The latest version of Analytical Warehouse Manager (10.1.0.4) is also installed and working prior to installing application server 10g(10.1.2)

This was originally working prior to the 10g Application Server install.
Any ideas as to what is going on...

Why Oracle Names have been discontinued in Oracle 10g

Hello,
I wanted to know why Oracle Names is not supported in Oracle 10g? Desupporting Oracle Names in future releases on Oracle is a big decision, as most of the sites still use Oracle 8i for legacy applications, which does not support OID. Translation tunnel between Oracle 8i ONAMES and Oracle 10g OID can be used... but what is the reason for not supportin ONAMES in Oracle 10g?
Regards
Sudhanshu

ONames is an obsolete technology. I suspect Oracle wanted to eliminate the need to support a code line that has an obvious replacement.
Those customers who still use Oracle8i obviously don't care about being supported by Oracle. Anyone who has a useable support contract will likely have upgraded, especially since Oracle gave lots of warning about desupporting Oracle8i, and even extended the desupport date.
Besides, there really is no conflict - use ONames for the unsupported legacy systems and OiD for the new systems. Or ... use the Oracle9i ONames & Oracle9i client against an Oracle 10g environment.
