I am working with Ubuntu 18.04. After installing sqldeveloper I correctly log in and get a list of databases. Upon doubleclicking on one database to show its content sqldeveloper becomes extremely slow. I receive the following message right after double clicking on a DB:
UsersCache.fillIn() time = 4 ret==null?: true
And then it takes approximately 10-15 minutes to load the database I clicked. After that time I can interact with the DB, but if I want to open another one I have to wait about the same time. The size of the DB is big, but on my colleague's machines it is a matter of seconds. I tried to uninstall and install it again but there is no way it speeds things up. Running it in verbose doesn't give more info than the one-liner I pasted above.
EDIT: top shows a CPU usage of approximately 180% on the sqldeveloper process.
Inspecting with top shows I'm using java-1.8.0-openjdk-amd64 to run
sqldeveloper
That is likely your problem. We do not support OpenJDK (or IBM's either for that matter.)
For the best experience we recommend and ONLY support the Oracle JDK - specifically, version 8.
I noticed on our download pages we do not say this specifically, but do point folks to the Oracle downloads for Java. I'll add a note/disclaimer so it is more obvious.
You can control the Java Home used or SQL Developer in the .sqldeveloper directory in your $HOME. There is a product.conf file in there, put the path to Oracle JDK 8 there.

I'm scared to ask this because people can be a little mean on here but I've watched 1000 of YouTube videos and went through just as many google searches. I was trying to create a data dictionary for mysql diagram. I used this website https://dataedo.com/kb/tools/mysql-workbench/how-to-export-data-dictionary#toc_0 to help me. I downloaded the .py link listed in the install plugin step. The followed the instructions in mysql. It said the plugin install was successful and to restart my workbench. After that I started getting the error shown in the picture. I have tried everything:
Restart workbench
Repair workbench through msi download
Followed the steps in this link: https://www.tutorialspoint.com/how-do-i-kill-all-the-processes-in-mysql-show-processlist
Updated all my sql products in mysql installer
Made sure mysql services were turned on and running
I don't know what else to do. I can't even open workbench to see if the plugin is the issue because again I can't get in. I just need some help
That is a strannge error, where mysql workbench has some corrupt files.
Deinstall MySQL Workbench with the MySQL Installer
Install Workbench again
So everything will start normal again, the configuration and connections will stay and can be used again as normal
This is not an installation issue, so don't waste your time by trying to fix this issue by repeating the installation.
The error comes from the approach where MySQL Workbench tries to ensure there's only one instance of it running. For that it searches the process list for another instance and, if one was found, sends the command line parameters it got to that instance, letting the already running instance handle them (and shuts itself down after that).
But again: this happens only if another instance is found, so check your process list carefully. Filter by the term "MySQL" to see any MySQL related processes (including that of a MySQL server). Shutdown/kill any of these processes and try launching WB again.
Same issue happened to me and it was like what the heck. Don't waste your time to uninstall and reinstall because it won't solve your problem.
Solution: open your file explorer and delete the entire folder "Workbench"
Path: %appdata%\MySQL\Workbench
I have the same issue with this file.
Just as Jr Relampagos says, delete the .py file here : AppData\Roaming\MySQL\Workbench\modules
Restart Workbench, it works for me.
With me I'm just go to C:\Users<USER>\AppData\Roaming\MySQL\Workbench\modules and then delete the .py file you install, then open the Workbench again
Since upgrading from MAMP 3 to MAMP 4, the GUI hangs on each action. Clicking something like the menu occurs after around 30 seconds of the spinning wheel of death. This happens for any action within the interface. Running 10.12.2
This almost makes the software unusable, as I can't configure the interface to begin development.
My experience was identical. Searching for some errors I ended up running Tools > Verify MySQL Databases... Among tons of OK'ed databases, several had errors - innodb_index_stats, innodb_table_stats, slave_master_info, slave_relay_log_info, and slave_worker_info.
From here a search lead me to mysql error: Table “mysql”.“innodb_table_stats” not found.
So, I deleted all the .frm and .ibd of the tables above and I ran the five-tables.sql file in Terminal: source five-tables.sql
Now MAMP Pro 4 runs smoothly and responsive.
Thanks, Kay Nelson.
I ended up doing a search for MAMP in all parts of the file, and removed every reference to it, after running the uninstaller.
I also removed references to any PHP & memcache not in the /Applications/MAMP folder.
I renamed /Applications/MAMP to /Applications/MAMP-old and reinstalled. This set everything up fresh and appears to be working. Something with a conflict with a system binary or other package was causing the issue.
At present I cannot run it (SQL Developer 4.1) because it hangs on "Restoring Editors" while starting. I suppose I've done it by exiting it before by killing sql developer process because it was hanged on fetching objects to Schema Browser so long...
Maybe I would clean some temporary files but can't find any.
Any ideas?
Deleting files from c:\Users\MY_USER\AppData\Roaming\SQL Developer\SQL History
and c:\Users\MY_USER\AppData\Roaming\SQL Developer\System...
Really helped me to resolve the connection issues
Basing on this thread https://community.oracle.com/thread/2564842 I've created own solution.
Extract installation of current version SQL Developer (4.1.0.17.29)
At "c:\Users\MY_USER\AppData\Roaming\SQL Developer\"
I've changed directory name system4.1.0.17.29 to system4.1.0.17.28.
After running newly extracted SQL Developer (4.1.0.17.29) I was prompted to let copy configuration from version 4.1.0.17.28 to 4.1.0.17.29 ;)
Everything works great now. I suppose that running the same (broken) installation after decreasing version could also help.
Remove folders c:\Users\USERNAME\AppData\Roaming\SQL Developer\system4.1.3.20.78\system_cache*. SQLDeveloper will recreate it after launching.
Just execute sqldeveloper as administrator. It works fine!
In my case the problem was because of windows compatibility issue. So I've selected my windows version and it's stop from randomly crash after startup
Our setup:
Windows 10
Sqldeveloper Versions <= 20.4.0
We observed this problem as well. Even worse while working over a VPN connection. I followed a couple of hints with more or less no effect.
To move
C:\Users\<USER>\AppData\Roaming\SQL Developer
to a local directory by adding this line
AddVMOption -Dide.user.dir=c:\temp\sqldev-conf
in the \sqldeveloper\bin\sqldeveloper.conf file gave us some improvement, but the “IndexPreferencesTask” still got stuck several times on startup.
After some more hours on unsuccessful research, we moved back from JDK 11 to JDK 8.
This solved 99% of the problem. The “IndexPreferencesTask” still hangs on startup but for less than a second.
Sounds to me like a problem with JDK 11.
In my case when i changed Tools --> Preferences --> Environment -> Look and Feel to Windows it is solved.
Delete the History files from C:\Users\User\AppData\Roaming\sqldeveloper
Restart the PC
In my case, the solution was kind of weird. After battling to resolve this for 2 days, no luck. Suddenly, on my mac, I searched for sql developer, not sqldeveloper. It popped up a sqldeveloper application (not sure how that is different from what I have been trying to open ), clicked it and boom, it opened. My guess is that there is a copy of that app on my system that I should have been opening rather than trying to open the reinstalled app. Note: I reinstalled the app after it started misbehaving though.
Operating System: Windows 10
Oracle Sqldeveloper Ver: 17.4.0
The problem has been noticed sometime when any network security
patch was installed on your machine. Looks like the patch impacts
your cached data under your user profile folder.
As above Lakh, rtbf and others answered. Removing below folders
will resolve the issue.
C:\Users\<userId>\AppData\Roaming\SQL Developer\SqlHistory
C:\Users\<userId>\AppData\Roaming\SQL Developer\system17.4.0.355.2349
If any one find more approriate reason please feel free to
disagree with my answer.
I'm having a problem with CCS6, which is based on Eclipse. I'm trying to build a demo project that comes with a TI MSP430 demo board. When I build the project CCS/Eclipse proceeds to clean the project, during which all the memory on my system is slowly consumed. After memory usage reaches 100% Windows declares that CCS/Eclipse is having problems and asks to close it down.
I am running Windows 8.1. I have uninstalled and reinstalled CCS several times, versions 5.5 and 6.0. I get the same behavior every time. I also updated the version of Java on my system. I have reached out to TI support engineers and they are baffled and useless. I have also tried with a second computer also running Windows 8.1, same behavior.
The problem is obviously rooted with gmake somehow. Perhaps there is something wrong with the project files causing this behavior? I haven't experimented with other projects yet.
Thanks!
P.S. I wanted to post screen shots but StackOverflow isn't letting me. The window I see in CCS/Eclipse is titled "Cleaning selected projects" and then reads "Invoking Command: c:\ti\ccsv6\utils\bin\gmake -k clean" And it just stays on this forever. Using Task Manager I can then see my memory slowly filling up. After about 5 minutes or so it reaches 100% use and Windows asks to shut down CCS.
I've developing an application in Eclipse 3.6 and am trying to get some simple execution profiling statistics with TPTP (basically just the execution time analysis).
However, the profiling is running so slowing that it's barely possible to get a successful run, Eclipse sometimes crashes with OutOfMemoryErrors and I highly doubt that any of the execution time statistics are anything close to what I normally get. I guess it's running about 100th of normal speed, using 100% of a CPU.
Any ideas as to what could be causing this and how I could fix it?
System is Core i7 980 running Windows 7 64-bit, JVM is Sun JDK 1.6.20 in case that is relevant
Did you try with this eclipse.ini file for some optimization and hopefully and better runtime experience?.
Note: keep the Java1.6u20, or make sure ti use the 1.6u21 build 7 (not build 6).
That way, you will ensure the --launcher.XXMaxPermSize parameter (that you should set to an high value in order to facilitate your session) will be correctly recognized.
please try this
following is the instructions to switch built in profiling database with newer version
close your eclipse ide
browse to your-workspace-folder/.metadata/.plugins/org.eclipse.dltk.core.index.sql.h2
copy all files under this folder to another location as a backup
and delete all files with .db extension
download latest version of H2 database for All Platforms zip from this link
goto your-eclipse-folder\plugins\ and find the file something like org.h2_1.1.117.v201105142352.jar and copy it to some place as a backup
extract the zip file downloaded on step 5
you will find the file h2-1.3.170.jar under h2\bin\ folder
rename h2-1.3.170.jar to the file name from the step 6 which is org.h2_1.1.117.v201105142352.jar
after this you can put the file renamed in step 9 into the folder your-eclipse-folder\plugins\
you can try to start your eclipse
please let me know if this makes your eclipse run faster
