SQL Developer starting very slow

Im using SQL Developer 1.5.4 on Windows XP pro service pack 3
It had been working fine for a long time. Then suddenly starting take a very long time to start.
It is taking about 1 minute to load the splash screen, then about 1 more minute for the progress bar to display and start, then a while to actually show the window. All together its taking 2 to 4 minutes to load.
Could this be something with reading TNSNames? I find it strange that it is taking so long to show the splash screen. This is also happening on other computers in my office. They all started doing this at the same time.
And ideas or suggestions will be greatly appreciated.
thanks in advance!

Have your systems recently had new Microsoft applications, updates, or patches installed? That happened here last weekend and one of the new items caused a noticeable slowdown (things were taking about twice as long). Once I totally disabled the offending item (Microsoft Desktop Search) and re-booted, things were back to normal.

SQL Developer is very slow...

I'm having performance issues with Oracle SQL Developer. I tried both and 1.5.4 and 2.1.0 (installed in Windows XP Professional) and both work very slow. When I connect to the same database in Apex or just the webconsole, performance is OK, so I think it's SQL Developer that's slow, not the database.
The problem is that the "Connected To Database..." screen with the "knightrider-bar" appears for some seconds for almost every action I want to perform (retrieving all views, showing constraints, triggers, etc...). Always the waiting screen appears for 3 - 5 seconds, which is very annoying.
Anybody knows what could be the problem? Working through the SQL Console in APEX is much more performant at this moment, but SQL Developer is more handy (if it would work faster).

Tom,
As well as the ide/bin folder, there is a sqldeveloper/bin folder, which has a sqldeveloper.exe as well as the one in the root folder.
Just as another thought - where is SQL Developer installed? Is it local on your PC or on a network drive? Especially when using the version with the included JDK, running off a network drive can be much slower.
theFurryOneOK, found it now. I opened SQLDeveloper there and the console didn't show any messages. When I connect to the database I got this message in the console:
Finished parsing = 15+
UsersCache.fillIn() time = 0 ret==null?: true+
I don't run SQLDeveloper from a network drive, it's installed locally on my C:\ drive. The database however is on a server, but I have a gigabit connection to it and applications don't have performance issues. So I suppose it's actually SQLDeveloper that's slow. Are there any tools in SQLDeveloper that could cause the bad performance, and that I could switch off?

Check your system Login/startup items in OS X System Preferences under the Accounts icon- Login items tab.
If you have more than 6 items trying to launch at startup, you need want to remove these apps from the automatic launch/startup list
Add or remove automatic items
Choose Apple menu > System Preferences, then click Users & Groups.
Select your user account, then click Login Items.
Do one of the following:
Click Add below the list on the right, select an app, document, folder, or disk, then click Add.
If you don’t want an item’s windows to be visible after login, select Hide. (Hide does not apply to servers, which always appear in the Finder after login.)
Select the name of the item you want to prevent from opening automatically, then click Delete below the list on the right.

Pulseaudio starting very slow

For some reason, pulseaudio is starting very slow on my system, even when it was a fresh install.
I was seeing very bad startup performance with several programs: firefox, hotot, etc. I did an strace on them and found they were stuck on waiting for a PID associated with pulse for about a half minute. When I turned off autospawn in the pulse config file, these programs loaded instantly, even if I put
pulseaudio --start
in my i3 config.
I'm not familiar enough to know how to debug this. Does anyone have any ideas of what I could do to get more information?
My sound devices are the integrated audio from my motherboard (Intel), my Nvidia graphics card, and my webcam (HD Dualpix).

Hi..
Not enough free space on the disk can slow the system down.
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
Try removing login items. Open System Preferences > Users & Groups then select the Login Items tab. Remove all items.
And go to HD > Library > StartupItems. Remove all items from the StrartupItems folder.
Check the startup disk.
Launch Disk Utility located in HD > Applications > Utilities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If the disk needs repairing, restart your Mac while holding down the Command + R keys. From there you can access the built in utilities in OS X Recovery to repair the startup disk.
Be aware, OS X Recovery requires a high speed broadband connection.
And backup all your important files before repairing or restoring OS X just in case.

My macbook starting very slow i want to factory reset

my macbook starting very slow i want to factory reset

Hello sallay Amir,
Thanks for participating in the Apple Support Communities.
It sounds like you would like to erase your MacBook Pro and install a new copy of OS X, but the Mac does not boot to OS X Recovery when you hold the Command + R keys during startup.
If your Mac came with OS X Snow Leopard (10.6) or earlier, I recommend referring to the steps in this article:
Mac OS X v10.6 Snow Leopard: How to Erase and Install - Apple Support
For a newer Mac (OS X Lion, Mountain Lion, Mavericks or Yosemite), try reinstalling OS X by using Internet Recovery, as described in the "OS X Internet Recovery" section on this page:
OS X: About OS X Recovery - Apple Support
All the best,
Jeremy

SQL developer starts and then disappears without any warning

Hi, guys:
I need to use SQL developer where there are existing connections. however, SQL developer 3.1 asked the java.exe location, and I chose java 6, now I can launch SQL developer but not able to continue running it. SQL developer starts and then disappears without any warning. Could anyone help me on this problem?
Thanks a lot!
Sam

Can you start the exe from the BIN subdirectory? That should open a command console, and maybe you can see any error messages there that explain what's happening. For step-by-step directions, here's some help:
http://www.thatjeffsmith.com/archive/2012/06/how-to-collect-debug-info-for-oracle-sql-developer/
OR
Install SQL Developer to a new directory and run it from there and see if that helps you get around your current install's issue.

SQL apply is very slow on Logical Standby..!!

Hello all,
We are having Data Guard setup in our environment where we are having Primary, Physical Standby as well as logical standby databases..
DB Version : 10.2.0.1 in all databases (Pri, Phy and Logical)
OS : RHEL4
Only Oracle is running on this Box..
Since last month we are facing problems in Logical Standby database where it seems SQL apply has become very slow..
Archive log files are successfully transferring from Primary but since SQL apply has become slow logical standby is lagging behind primary by two days..
How do i speed up this SQL apply..?? Any ideas and suggestions are most welcome..
I checked TOP command to find out which oracle processes are consuming maximum CPU and i have found ora_p000_oracle, ora_p001_oracle, ora_p002_oracle, ora_p003_oracle, ora_p004_oracle, ora_p005_oracle, etc processes are consuming highest CPU and Load Average has always been above 1..
Any help would be greatly appreciated..
Thanks - HP

Lightroom Develop Mode very slow in responding to commands

When I am trying to get a photo ready to print and am in the Develop window, the response time when I try to make adjustments to the phots are not acceptable. Very, very slow and almost impossible to accomplish what I need to do in order to get the photo into the print mode. I have a hang up somewhere but I am at a loss to know how to correct this problem. Any help greatly appreciated

I've got this exact same problem and I've tried a list of things to do. I've been on the internet researching this out for two days and nothing has worked. I have 3 sessions I need to get done and this slowness is unacceptable. LR used to run very smooth and fast and with in the past week its been a dog. It has to be something related in the catalog area. I have 13000 and the catalog is a mess. I don't understand the catalog one bit, I'd rather just have access to folders and upload that way instead of messing with the headache of a dang catalog.........did I say I hate the catalog?
Things I've tried with no results:
optimized catalog
moving RAW cache from external to internal drive
increasing RAW cache from 2G to 20G
preview rendering 1:1 (I really don't understand the purpose of this at all....after waiting for an hours to render 500 photos it did nothing to improve)
Moved a session of photos that I have been trying to work on from my external drive to my desktop (500 photos 10G worth) internal drive
reboot PC
reboot LR3
disabled unused startup programs
my PC is scheduled to defrag once a month
attempt to update Intel graphics driver but there was no new update to download
close all programs and run LR3 by itself
I may have failed to list something but I think thats it. I'm running Win7, Intell Duo Core 2 T6500 2.10Ghz processor, 320HD with about 70% free. I only use my HD to run programs and a external 320HD for image storage and retrieving. This particular drive has about 30% free, maybe less, but like I said before I've disconnected the drive and tried developing from my internal drive with the same results.
I'm out of things to try.........shoot to them over to me and I'll try it. I'm desperate. I'd love to dump the entire catalog and start over. Its so unorganized and I never can find what I'm looking for anyways......I hate that catalog with a passion but I love everything else about LR when its working.

SQL Query Report Very slow

Hi I have a sql query report that is taking very long to render.The query on sql developer comes back in less than a second.Any ideas on what could be wrong?

Hi
When posting code on the forum, put {noformat}{noformat} (with the curly brackets and the word code in lowercase) above and below your code like this...
{noformat}{noformat}
SELECT *
FROM emp
{noformat}{noformat}
It will then appear like this, preserving formatting...SELECT *
FROM emp
Next, how many rows are returned in total, it may be that you have SQL Developer set up to fetch only the first x number of rows?
Why have you put a CHOOSE hint in there?
Is it a classic report or an interactive report?
It looks like you're going over a database link, you really need to provide an explain plan (formatted as I have detailed above), a DRIVING_SITE hint may help you but it's impossible to know without seeing the plan...
Cheers
Ben

Imac starting very slow

Since a few day my iMac is starting very slowly (at least 5 to 10 min). I don't know if I have done something wrong or my childrens...
Soft is up to date. I've got a HDD external for Time Machine but I have the same trouble with or without.
Only one internal HDD.
The model is 20 inch from early 2008, running under OS X Lion 10.7.5 (11G63).
Thaks for your help.

SQL Developer starts every time as if first time and ingores preferences

Every time I launch SQL Developer, it offers me to configure file type associations. Also, many preferences, such as tab settings for editor, while preserved between sessions, have no effect. Other settings, such as the interface style, work normally.
Windows Vista Business 32bit
SQL Developer 1.2.1 Build MAIN-32.13

The file associations thing means you don't have access to the registry to associate file types. Probably connected to the Vista security model. Try registering the filetypes for use by sqldeveloper through explorer.
This other problems generally means you don't have write access to the sqldeveloper system directory.

What is causing Google Chrome to start very slow?
