3 of 300000 JDBC UPDATE iterations take 20 seconds
I have a performance problem during update operations via JDBC.
There is a single instance of TimesTen on one host, no replication, checkpoint is on, logging is on.
I have one thread where I perform UPDATE operation in infinite loop. After 1000 iterations application sleeps for 10 milliseconds to prevent full CPU usage.
According to the statistics, the performance is quite good (3000 TPS), but in each 300000 iterations (they take in average 0.33 milliseconds each) there are 3-4 iterations, each of them takes about 20 seconds!!
When I turn loggging off (set Logging=2), the problem dissapear. But I can not disable logging because I need replication and replication requires parameter Temporary=1 either (it means no checkpointing).
How to avoid iterations that take 20 seconds?
Thanks in advance.

Hi,
This is a possible solution but the downside to this is that checkpoints nwo will take much longer. Before resorting to the checkpoint throttle you should try the following:
1. Set LogBuffSize=65536 and set LogFileSize=64. If necessary you can even go bigger to LogBuffSize=131072 and LogFileSize=128.
2. Be sure to allocate your checkpoint files and log file to different physical disks. The location of the checkpoint files is definied by the value of the DataStore ODBC attribute. By default the log files go in the same directory but this is very bad for any real-world write-intensive configuration. You can use the LogDir ODBC attribute to place the log files in a different directory (on a different disk!).
3. Set CkptLogVolume=0 and unset CkptRate.
In order to change LogDir you must destroy and re-create the datastore.
You might want to try this first before you start playing with the CkptRate parameter...

SAP XI JDBC update SQL statement
Hi,
I am new to JDBC to RFC configuration and is currently on a deadlock.
We are running a real time JDBC update statement where records are created based on employee login. We have configured the sender adapter to retrieved 5 records for every 5 seconds using the SQL query below:
select * from dtable where uploaded=false order by recordno asc limit 5;
and update using:
update dtable set uploaded=true where uploaded=false order by recordno asc limit 5;
The problem is that when there are only 3 records retrieved in the selection, the update statement always update 5 records back. This makes records created in-between the select and update to be updated as well.
Can anyone suggest the correct update statement? Can I use the record numbers retrieved from the first statement in the update?
Thanks,
RyanHi,
>>>>Can anyone suggest the correct update statement?
1. you have a few choices but one of them would be to use a stored procedure in the select statement (which would have both select and update statements)
2.
a) select * from dtable where uploaded=false order by recordno
b) update dtable set uploaded=true where uploaded=false
c) split them by 5 rows in the mapping (multimapping)

Update statement takes long time - Why so ?
Dear DBAs;
Daily update statement takes 20 mins. But today update takes more time.
What is the reason how to resolve ?
Thanks in advance ..8f953842-815b-4d8c-833d-f2a3dd51e602 wrote:

Hi Friends,
I have a issue in proxy to JDBC update. there are onley 4 fileds to be inserted into table..
And before inserting the fileds into table i need to check whether the fields are there or not if not insert if they are then update,, i need to check all the four fields. for this..
Any way to solve this kind of issue..
Regards
VijayBut what is the need of it?
In both cases you have to perform some action on database.
1. If records are there then Update
2.If records are not present then Insert.
So if even you check the records prior to sending it to database....you have to do the same(Inster or Update) and UPDATE_INSERT is possible with JDBC rec. adapter.
Then why you need to check it? Is there any business logic behind it? Or you it was jut for practive purpose?
Thanks

Why does it take 30 seconds to sleep after the 10.7.3 update?
After applying the 10.7.3 combo update it now take 30 seconds between the time I select sleep from the menu (or press the power button) on my 2.66GHz Mac Pro. It used to be instant.
Matthew,
Again, this started when I installed the combo 10.7.3 update. Unlike you, my screen does dot go to black-except-cursor, but remains at the desktop (or whatever app I'm in), but simply takes 30 seconds exactly to sleep. I do have a Belkin UPS attached, and I'll try to unplug the USB cable and see what happens. Also remember that I've tested this in a new unsullied user, so it's probably not anything I'm running. Another possibility is that I have 2 RAID arrays connected via eSATA, but I had those before the update and they did not seem to affect sleep then. Could be that Apple changed the way they handle eSATA.
I'm on a 2006 Mac Pro (details below).
Would be nice if we could get some help from an Apple engineer on this issue (hint, hint...)

I did the update to take out bugs etc; now when I try to open an app, it asks for my Itunes ID before it will open; this is a pain; has anyone else had this problem or knows how to correct this, assistance gratefully appreciated, thanks
Please tell me that it has NEVER been jailbroke. If it has never been jailbroke, here are some standard repair procedures:
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, read this. -
Hi, Sir::
I use following simple JDBC Update program to update my table TEST,
See following code:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
// create table test(Test_ID number, Test_Val varchar(30));
public class Update {
public static void main(String args[]) {
Connection con = null;
if (args.length != 2) {
System.out.println("Syntax: <java UpdateApp [number] [string]>");
return;
try {
String driver = "oracle.jdbc.driver.OracleDriver";
Class.forName(driver).newInstance();
String url = "jdbc:oracle:thin:@localhost:1521:usa";
con = DriverManager.getConnection(url, "scott", "tiger");
Statement s = con.createStatement();
String test_id = args[0];
String test_val = args[1];
int update_count = s.executeUpdate("INSERT INTO test (test_id, test_val) "
+ "VALUES(" + test_id + ", '" + test_val + "')");
s.executeUpdate("UPDATE test SET TEST_VAL= 'John Alan' WHERE TEST_ID=1");
System.out.println(update_count + " rows inserted.");
s.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
if (con != null) {
try {
con.close();
} catch (SQLException e) {
e.printStackTrace();
When I run with command:
C:\temp\javaCode>java Update 2 MyTest
It hangs here and did not process, If I remove the statement:
s.executeUpdate("UPDATE test SET TEST_VAL= 'John Alan' WHERE TEST_ID=1");
it works and insert 1 record into Test Table.
What is wrong here??
How to fix it??
Thanks
SunnyDid you try with another Statement? I would try closing the first statement and creating a new one.
Class.forName(driver).newInstance();
String url = "jdbc:oracle:thin:@localhost:1521:usa";
con = DriverManager.getConnection(url, "scott", "tiger");
Statement s = con.createStatement();
String test_id = args[0];
String test_val = args[1];
int update_count = s.executeUpdate("INSERT INTO test (test_id, test_val) "
+ "VALUES(" + test_id + ", '" + test_val + "')");
// close it and create a new one
s.close();
s = con.createStatement();
s.executeUpdate("UPDATE test SET TEST_VAL= 'John Alan' WHERE TEST_ID=1");
Let me know if it works. -
My iMac seems to have frozen during the update- how long should I expect the update to take? The 'installing software update' bar is still showing itself working but has been stuck in the same position for over an hour. Any thoughts?
Update2: There is something very wrong with wireless on mountain lion recovery. I don't know what the problem is, but this link may explain:
http://osxdaily.com/2012/08/10/os-x-mountain-lion-10-8-1-beta-released-for-dev-t esting-may-include-wi-fi-fix/
Wireless recovery would start out with over 25 hours estimated and kept on failing. It turns out to be a two step process of downloading a few Mbytes then a 4Gbyte .dmg file, but I couldn't even download the Mbyte file. I bought the thunderbolt to gigabit ethernet adapter, plugged it in, restarted recovery and download of a little more than 4Gbytes took less than an hour. My limiting factor was probably comcast home internet rate of 12Mbps. The wi-fi wireless connection should be able to do over 100Mbps, so wireless shouldn't be much slower than wired, except wi-fi wireless is broken. Now that ML is installed and updated, wi-fi seems fine now, as I am using it right now, but I haven't tried downloading a big file yet.
Don't use wi-fi wireless for Mountain Lion recovery. -

Update without take application of WebConsole
Hi,
For example... Device is with version 1.0 of app and will be create the version 2.0.. It there a way to update without take application of on MI Client?
Thanks.
Regards,
BrunoHello everyone,
I agree with what divya has said. This is surely one way of doing this.
But there is a slight problem to it. Some times after you have given the path to the updated .war file, these changes get reflected instantly if you have assigned the appln to the same device as before.
But the problem comes when you try to assign this updated appln to some other device. Many a times this other/new device gets the older version of the appln.
This is a problem I have faced many a times. So i feel that once you are sure of the changes you have made locally, it is better to create another version of the same appln.
Uninstall the older version for the user/device. Sync your device atleast twice.
Now you can delete this MCD of the older version from the webconsole.
Assign the new version to the user/device or any other user/device. Sync and get going.
Cheers,
Saurabh. -

Should an iphone software update really take 3 hours?
should an iphone software update really take 3 hours?
It depends on a number of variables. It could be the speed of your internet connection, if you are trying to update OTA versus direct connection in iTunes, the amount of data, music and apps that need to be synced back to the device after the update. You can always remove the device from iTunes and perform a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. The device may have completed the update and just not displaying correctly. If you do remove and it is not updated, just connect again and start the update again.

A workaround was suggested by a member of the community to turn off both hardware and Flash acceleration. It worked fine (no crashes since), but runs very slowly. In particular, takes five seconds to exit and is often still listed as a running process. Very slow in connecting to Web pages, and very slow loading them because of the graphics. Very slow in loading video. I expected slower responses, but this is REALLY slow. I'm running 64-bit Windows 7 and an Nvidia GE Force 7800 graphics card with all the drivers updated and the plugins for Firefox mostly set on "ask to activate". Should I expect this much reduction in performance when the workaround I mentioned was put into place? If so, it's half a loaf at best. The only thing questionable is that I have two Youtube downloaders that I am trying, but I made the assumption that these were only applied when you downloaded something from Youtube.
In case you are using "Clear history when Firefox closes": do not clear the Cookies
If you clear cookies then Firefox will also try to remove cookies created by plugins and that requires to start plugin-container processes that can slow down closing Firefox.
Instead let the cookies expire when Firefox is closed to make them session cookies.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Keep until: "I close Firefox"
