Oracle 10g - query is very slow in jdbc but not in other tools

I'm using PreparedStatement to execute a query with some parameters.
in sql developer, it just spends 12 seconds but in jdbc, it's around 140 seconds.
I disabled "_optim_peek_user_binds" parameter already but it didn't help.
alter session set "_optim_peek_user_binds"=false;

Please mark this thread ANSWERED and repost it in the JDBC forum.

When you post provide your 4 digit Oracle version, Java version and JDBC jar name and version as well as the code you are using.

Insert query is very slow on prod but is very fast on the local

Hi,
An insert statement ( bulk insert..) takes around 45 minutes to insert 25,000 records in prod but the same in our local env( local env is a copy of production) takes 3 minutes for inserting 1,50,000 records . This is a very huge difference. The explain plan of queries on both the env is same. The query is a simple join between a GTT ( 25,000) and a normal table ( with 10 records).
I still dont have the trace for the query from prod . The database version on prod is 11.1.7 and the version on local is 11.1.6
In the mean time while I wait for the trace it would be really helpfu If any of you can let me know the parameters /next steps that should be followed. I have compared the session level parameters on both the env and its the same.
Thanks in advance
Kevin

Look for cost, bytes, and rows. These numbers can be off-base since they're estimates, but I'm wondering if the values are the same on both systems. Different values could mean the CBO is interpreting the data as having different characteristics. "almost the same" could suggest the CBO is making different decisions - not all operations are listed in execution plans. For instance, I've seen sort operations taking place from V$SESSION_LONGOPS when no sort was directly listed in an execution plan.
I was hoping you could get wait information from the 10046 trace :(

My BlackBerry Messenger is very very slow. I am not receiving the messages in a timely fashion.

Do you mean your iPhone got wet in the rain? If so, turn it off, put it in a plastic bag with some uncooked rice and let it dry out for several days (minimum). You might want to change the rice out every day too, especially if you notice it swelling (from moisture coming out of the phone).
Continue to use it and you risk further harm from continued water damage. If it does not work after drying out, then you can take it to Apple and pay for an out of warranty exchange (water damage voids the warranty, so you would have to pay the replacement fee).

The first time I start Firefox it is very slow coming up but after it is up and I want another window it fast again. What do I need to do to clean out whatever is clogging it up.

Question
The first time I start Firefox it is very slow coming up but after it is up and I want another window it fast again. What do I need to do to clean out whatever is clogging it up. edit

* The first time you start up any application after turning on your computer is called a cold start, which is why Firefox takes a while to load right away. (I've noticed that future versions of Firefox start up faster on a cold start then Firefox 5.0.1.) Also, a lower amount of RAM could be slowing its start-up down since Firefox is kind of memory hungry.
* As for the second part of your question, press ctrl,Alt, and the delete keys on your keyboard. The Windows Task Manager should start. Go to the processes tab and look for 'firefox.exe'. Right click on the firefox.exe and click 'End Process'. Hit Yes and wait for a minute.
* Then opening Firefox again.
Hopefully this helped somewhat!

Oracle query running very slow

Hi,
We've MS-Access application which was pointing to UDB. Now we migrated it to point Oracle DB 9.2. After migration some of the query is running very slow.
These queries used to take less than 30 seconds in UDB now taking more than 5 Minutes in Oracle.
some more obeservation :
(1) Some of the queries using "HAVING" clause without any aggregate function. When I moved this condition to "WHERE" clause, performance improved a lot.
But problem is that I can't suggest this solution to "USERS". They are creating query using "query wizard" in MS-Access and they started creating noise on this.
(2) I tested same MDB in two different PCs and same query is returning records in 4 seconds in one system, is taking more than 10 minutes in other system.
Since I'm new to MS-Access, I don't know what other information I need to provide here.
Please help me out.

1) what is the difference between a index on one column and an index of number of columns ( i.e composite index). The obvious answer of one contains only one column and the other contains more than one.
2) For what columns in a where clause should index be created ( single columns index or composite index ).Depends

Oracle 11G - Update is very slow on View

I have big trouble with some Update query on Oracle 11G.
I have a set of tables (5) of identical structures and a view that consists in an UNION ALL of the 5 tables.
None of this table contains more than 20 000 rows.
Let's call the view V_INTE_NE. Each of the basic table has a PRIMARY KEY defined on 3 NUMBERS(10,0) -> INTE_REF / NE_REF / INSTANCE.
Now, I get 6 rows in another table and I want to update my view from the data of this small table (let's call it SMALL). This table has the 3 columns INTE_REF / NE_REF / INSTANCE.
When I try to join the two tables :
SELECT * FROM T_INTE_NE T2
WHERE EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
I get the 6 lines in 0.037 seconds
When I try to update the view (I have an INSTEAD OF trigger that does nothing (just return for testing even without modifying anything), I execute the following query :
UPDATE T_INTE_NE T2
SET INTE_STATE = -11 WHERE
EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
The 6 rows are updated (at least TRIGGER is called) in 20 seconds.
However, in the execution plan, I can't see where Oracle takes time to achieve the query :
Plan hash value: 907176690
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |

What could explain the difference ?
I get exactly the same execution plan (when autotrace is ON).
Furthermore, if I try to do the same update on each of the basic tables, I get the rows updated instantaneously.
Is there any reason for avoiding this kind of query ?
Any help would be greatly appreciated :-)
Regards,
Patrick

Sorry for this, I lost myself in conjonctures and I didn't think I would have to explain the whole case.
So, I wrote a small piece of PL/SQL that reproduces the same issue.
It seems that my issue is not due to the UPDATE but to the use of the IN predicate.
As you can see at the end of the script, I try to join the 2 tables using different technics.
The first query is very fast, the second is very slow.
I need the second one if I want to do any update.

It is always a good idea to use the standard ports for a network application. There is no logic in obfuscating ports for security purposes. It also makes network management and dealing with quality of service issues for example, much more complex if you do not stick to the registered application ports.
Also note that if you provide a dotted IP address, only that address will be used for binding the tcp port as a listening end point. This means no connections will be accepted on localhost and other IP addresses of that server. Make sure that this is what is technically required.

bond6     Link encap:Ethernet HWaddr 00:26:55:D3:02:B6
Why are you using bonding? How many bonded interfaces are there and now many physical NICs? Bond6 alludes that it is the 7th bonded interface - and at 2 NICs per bonded interface it implies that your server has 14 physical Ethernet interfaces. Which I doubt is true.
RX packets:1309675596 errors:5 dropped:0 overruns:0 frame:3Not good to see any errors. What does ethtool stats show? Also check that the physical interfaces are enabled for full duplex. Some Cisco switches do not negotiate it properly and the NIC could be running half duplex.
Also - using bonding... does not seem right. The 1st and default bonded interface should be +/dev/bond0+ - and not bond6.
Check the server's network configuration (the +ifcfg-*+ files in +/etc/sysconfig/networking-scripts+ directory). Suggest that you get a network engineer (or the like) to assist with reviewing the network setup of that server.

Oracle 10G query

I have following queries to be solved please help me out....
1) Difference / Limitation of Oracle Standard Edition / Enterprise Edition 10..... latest ?
2) Can Data of Oracle 8. ..... Expo File will be Imported to 10....... latest ?
If not than what steps we have to take. Basically I would like my current DB of 8 to be moved to 10G
3) From which AIX Ver Oracle 10 ...... is Supported ?
4) if the customer has 8... Ver Lic When if goes for New Ver than media will have full Ver or only Upgrade files. ?
5) If the Customer has Old ver Lic and he goes for upgrade Lic Than we have to first Install Old Lic Ver & than Upgrade or directly we can load Latest Lic Ver on New Server and work. ? What I mean is if I have to go ahead from Oracle 8 to Oracle 10G how should I go about.
6) Is Oracle Media ver Compatible for Aix ?
7) Oracle Lic Policy / Product Information Web Link ?
Thanks & Regards

This is a perfectly valid way to query the data. Here's an example on my own production tables. This one has about 300 million rows:
select *
from   prod.tran_history
where tran_date >= to_date(add_months(sysdate, -2))
| Id | Operation                   | Name                        | Rows | Bytes | Cost |
|   0 | SELECT STATEMENT            |                              |    11M|   863M|   146K|
|   1 | TABLE ACCESS BY INDEX ROWID| TRAN_HISTORY                 |    11M|   863M|   146K|
|* 2 |   INDEX RANGE SCAN          | TRAN_HIST_DATE_IDX           | 2144K|       | 2098 |

down vote
favorite I am using oracle 10g. I have a temp table TEMP.
TEMP has following structure:-
USER COUNT TYPE
1 10 T1
2 21 T2
3 45 T1
1 7 T1
I need a query which will show all types has column names,and types can be any value like T1,T2,..Tn and columns will be like:-
USER T1 T2 Tn
and User column will show all the users and T1,T2 column will show total count of types.

Please see my original post ("I have a page erroring in production (but not in development) when it gets to a date that it needs to display.") Sorry if it came across as vague. It made sense, to me, when I typed it. But, then, I'm usually typing fast just to get the question out there, when I'm in a hurry.
Haven't done a CFDUMP, yet, as every time I make a change in development that needs to be tested in production, I have to notify my supervisor that there are files that need to be copied into production, which can sometimes take a while, so I try to do troubleshooting on dev side - it's a pain in the you-know-what, but that's the kind of environment I'm working in.
As it turns out, changing the format in the SELECT to_char() did the trick. If anyone else has this issue with Oracle 10g, I'm now using SELECT to_char(create_date,'YYYY/MM/DD HH:MI') FROM tableA, and now the CFOUTPUT is processing the whole page. I guess the MM-DD-YYYY threw CF into a tizzy, breaking the process?
Anyhoo, it's working, now. Thank you, Dan and Adam, for your thoughts on this.

Calling java from pl/sql in oracle 10g?its very urgent.

Hi Friends,
i hve simple java code:
class Hell
public static String Hello()
return"hello world";
& compile this code using javac & loaded Hell.class in to database using this command
c:\>loadjava -user chandru/shekar@pulser c:\Hell.class
& i wrote pl/sql like:
CREATE OR REPLACE FUNCTION Hell RETURN String as language java name 'Hell.Hello() return java.lang.String';
i will compile the code & run but at that time this error i am getting:
ORA-29516: Aurora assertion failure: Assertion failure at eox.c:317
Uncaught exception System error: java/lang/UnsupportedClassVersionError
I am using oracle 10g.Plzzzzzzzzz help me.Its very important to for me.
Is any path i hve to set for oracle 10g database.Plz any one help me.
regards
shekar

Hello here is how I solved the problem
Let us assume that i try to load the file Hello.Java into the user scott.
public class Hello {
     public static String world() {
          return "hello world";
1) Dropjava
You must drop the java class if you already have loaded the class onto the server.
dropjava -u scott/tiger Hello.class
2) load class on server and let the server compile the source code.
It is necessary to compile the source code on the server when the server and the local machine have different Java versions. To check which Java version there is running on the client machine open a command prompt and write Java -version
loadjava -user scott/tiger -resolve Hello.java
3) Publish stored procedure
sqlplus scott/tiger@oracle
CREATE OR REPLACE FUNCTION helloworld RETURN VARCHAR2 AS                LANGUAGE JAVA NAME 'Hello.world () return java.lang.String';
4)Call stored procedure
VARIABLE myString VARCHAR2(20);
CALL helloworld() INTO :myString;
PRINT myString;

10g forms applet very slow

I've just converted a couple of 6i client server forms to 10g.
I'm using the Developer suite 10gR2, with its own built-in oc4j server.
It all works fine, after some fiddling to get icons loaded etc.
But the form is 10 times slower than in client-server. This is a total show-stopper for us. A form that took 2-3 seconds to load before can now take nearly a minute to come up.
Even our very simple login form is slow, many seconds instead of a fraction of a second.
I've tested on the workstation thats running the OC4J, This is a Dual-Xeon 2.4Ghz with 2G of memory, so its NOT the hardware. Its running XP-Pro.
Then I tested on a workstation, using a dummy html page to launch Jinitiator and get the form up. JInitiator installed itself perfectly, but erformance is exactly the same even though its a P-III-800 with only 256M of memory.
The strange thing that we notice is that the performance monitor on the oc4j server machine shows it as almost idle (3% cpu, almost no network traffic and idle disk).
But on the workstation the cpu is at 80-90% all the time, even when the form is just sat there waiting for user input!
So we think we have some sort of applet mismatch or configuration problem. Is there a newer (or older?) applet version thats quicker, or doesn't nail the cpu this way?
My next step is to download just the forms-and-reports services for linux and put that up on a second identical box that has Redhat-ES.
Has anyone else seen this sort of applet behaviour? if so any suggestions would be a great help because we're stumped at the moment.

Good feedback folks, but I still don't see any explanations of whats happening, or why it should be slow.
I'll agree that putting the icons in a single file, one jar archive per form, is definitely more efficient. Putting all your icons in one file strikes me as silly since then you have to download all the icons, even if you never bring up forms that use some of them.
BUT gentlemen, it does not explain why we had the problem I described. I see no reason to suspect that the jar file would fix my problem, (of course I'll try anyway).
The point here is that the form was slow to start, OK, maybe that was because it was individually fetching 15 or 20 icon files.
BUT WHY SHOULD IT THEN BE SLOW AFTER THAT!
Sorry to shout but no-one seems to be hearing what I'm saying here:
1) the applet has the CPU locked-up at over 90% all the time
2) the cpu is at 90% when the form is idle waiting for input.
3) the form has completed painting the user interface just fine, I can see everying,
including all the icons, it all works right, its just slow.
4) its not surprising that its slow since the applet has the cpu pegged
5) we get the same pattern of behaviour on a form that has exactly one icon,
for a download of one file, a total of 232 bytes.
Now there is no way you can claim that a jar archive is significantly faster
than a single gif file download, they are both cached and the sizes are both so small that any difference is insignificant.
It looks to me like a bug in the applet, or some sort of configuration or set-up error on my part. But I can't find any documentation on how to control that. The applet itself appears to be very much a black-box with no visibility into whats going on inside it. No trace file, no log file, no debug options.
I mean debugging the applet itself here, not the form that the applet is presenting to the user.
I'm going to work on bringing it up on Linux today, for now I'll just run without icons while I get the forms/reports integration running. Then I'll come back to the icon issue next week. Maybe if I switch to jpegs the problem'll go away. SO I'll post a follow-up sometime next week.

Query runs very slow and sometime freezes

Hi Experts,
I have just installed SAP GUI 710 but when i open a query in analyzer it runs very slow and if the variables are set for more than 6 months it just sits there and finally times out. It takes at least 5 minutes to open the query if it opens at all. Can you please advise me on how to resolve this issue??
Thanks, point will be awarded.

Oracle HTTP JSP gets very slow on 9i

PLateform : Windows 2000
I have changed from Oracle 8i to Oracle 9i. Than I
installed Oracle Chartbuilder from
http://otn.oracle.com/software/tech/java/servlets/htdocs/utilsoft.htm
On the 9i Apache this application runs very very slow
It looks a little bit like he is compiling the jsp
every time it is called.
Does anybody know whats wrong or where I have to configure something ???

1. Are the database parameters the same on each of the systems (ie. LARGE_POOL_SIZE)? You may want to check on any potential bottlenecks during the restore by looking in V$BACKUP_SYNC_IO and V$BACKUP_ASYNC_IO.
2. You can limit the amount of datafiles included in a backup set by setting the MAXSETSIZE parameter. Be careful not to set this value too low. If a datafile is bigger than MAXSETSIZE, then the backup will fail.
