I have a fresh installation of Cassandra 3.7 with DatStax DDC in Windows. I am trying to start the Cassandra database as a service.I am using net start DataStax_DDC_Server to start the service. The service is not starting and exiting without reporting an error. I am getting the following error in the logs.
java.lang.RuntimeException: Failed to create failed snapshot tracking file [C:\Cassandra\.toDelete]. Aborting
at org.apache.cassandra.db.WindowsFailedSnapshotTracker.deleteOldSnapshots(WindowsFailedSnapshotTracker.java:99)
at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:177)
at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:585)
at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:714)
What is causing this error and how do I fix this?
Look at the logs in the installation folder. E.g. c:\Program Files\DataStax-DDC\logs.
The datastax_ddc_server-stderr.xxxxx.log will give you details about what the problem is. For me the error was cdc_raw_directory is missing and -Dcassandra.storagedir is not set so i opened c:\Program Files\DataStax-DDC\apache-cassandra\conf\cassandra.yaml, found the cdc_raw_directory setting and simply uncommented it.
After fixing that you also get an Error when you will try to run cassandra.bat from command line.
it will tell you that \conf\\\hotspot_compiler cannot be found
Fix:
go to C:\Program Files\DataStax-DDC\apache-cassandra\conf
modify cassandra-env.ps1
just change CASSANDRA_CONF\conf\hotsport_compiler
to CASSANDRA_HOMEconf\hotsport_compiler
WITHOUT the backslash... this is not a typo ^^
finally cassandra.bat will start and cqlshell will work.
.. then close the command window where you started cassandra.bat (as admin) press CONTROL+C
..and finally you can start the service as admin: net start DataStax_DDC_Server
Below is the process that i followed to get my cqlsh working on windows 10 (64 bit)
Msi Installation file used : datastax-ddc-64bit-3.9.0
After i have installed datastax:
1) Opened cqlsh, it started closing on me.
2) researched answers in stack overflow and found that i need to add raw directory.
3) Based on TugboatCaptain answer I enclosed cdc_raw_directory based on my installation folder in conf\cassandra.yaml file
4) Opened Errlog file and noticed there is mistake showing in the path "C:\Program Files\DataStax-DDC\data\cdc_raw" at "\DataStax-DDC" error while scanning double quoted scalar.
5) I removed "\" before "DataStax-DDC" from cdc_raw_directory value in conf\cassandra.yaml file and started Datastax DDC Server 3.9.0
6) Opened again the Err file and noticed the error is shifted to "\data"
7) I removed "\" from cdc_raw_directory in conf\cassandra.yaml file and saved the file and started Datastax DDC Server 3.9.0
8) Opened again the Err file and noticed the error is shifted to "\data"
9) repeated the process of removing "\" and saved the file until i was able to start the service.
10) Finally my service started, Hope this helps and also attached screenshots from my pc.
Finally my cdc_raw_directory value looked like below:
Final Image from "conf\cassandra.yaml" once my service has started
This is the my cqsl shell screenshot
Mylog file(logs\datastax_ddc_server-stderr.2019-03-24.log) screenshot
I had the same problem (I'd start and it automatically says service stopped). I got it fixed as follows:
go to C:\Program Files\DataStax-DDC\apache-cassandra\conf
edit cassandra.yaml
change
cdc_raw_directory: /var/lib/cassandra/cdc_raw
to:
cdc_raw_directory: "C:/Program Files/DataStax-DDC/data/cdc_raw"
Make sure that there are no spaces before "cdc_raw_directory" i.e. not " cdc_raw_directory" because Python is space sensitive
Try running the CMD prompt as administrator, that fixed the problem for me.

While installing the Weblogic in windows 10 using jar file, I am getting the error message as Unable to access or modify the system registry. Select Run as Administrator when opening the Command Prompt and try again. though am executing as Administrator. From the log file I got the below error.
WARNING [1] com.oracle.cie.common.jni.WinRegistryHelper - Create Key Failed: HKEY_LOCAL_MACHINE\Software\Oracle
2017-10-06 11:19:54,972 SEVERE [1] com.oracle.cie.nextgen.launcher.PlatformHelper - createRegistry to add a value failed

I understood that on making the System Registry entry HKEY_LOCAL_MACHINE\Software\Oracle, it is failing because the same entry already exists in my system as HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE. Though system registry is case-insensitive, weblogic is failing on making entries to this registry. Is there any solution to overcome this? The same issue has been already posted in different sites but not yet answered.Any help to solve this issue will be really appreciable.
I had the same problem, the next lines works to solve the problem.
Open cmd like administrator.
java -d64 -jar fmw_12.2.1.3.0_wls.jar If you don't have correctly configured the JAVA_HOME, you can replace the word "java", for the path where you have installed de JDK. Something like this:
C:\JRockit\jdk1.8.0_144\bin\java.exe
I installed PostgreSql on my Windows machine.
I can connect to PostgreSql through cmd.
But when I want to launch pgAdmin I am getting this error message.
Failed to connect to the pgAdmin application server. Click here to try again.
I have also Mysql installed on my machine if it can make any complications.
The same problem happened to me today:
And this is how I've solved it:
1) Use a text editor to open the config_distro.py file under the c:\Program Files\pgAdmin 4\v1\web folder. Change the value for SERVER_MODE from True to False, then save the change. (I have run Notepad++ as an Administrator, in order to be able to save in this protected folder.)
2) Go to folder c:\Users\your_name\AppData\Roaming\pgAdmin and make sure there is nothing there (delete all the files, as they are temporary and will be restored after starting pgAdmin)
3) Start pgAdmin
4) This time you will see a white box that sits - at least, on my slow laptop - about 20 seconds. (You may briefly see the original error message, but do not worry).
5) Meanwhile, the temporary files - required for running the application - are created.
6) Once the temporary files process is over, the application starts as expected.
Try starting the pgAdmin as administrator.
My config_distro.py was missing this line:
MINIFY_HTML=False
I added it as in the above steps and it works
In my case, SERVER_MODE was already False in config_distro.py. I then proceeded to start pgadmin4 as an administrator. This also did not work. Finally, I resolved this by restarting postgresql service in services.msc.
postgres service restart
In my case, the problem was non-ascii username.
Find pgAdmin installation and open/create config_local.py in editor, add this:
DATA_DIR = "C:/Data/pgAdmin" # set non-ascii path here
and run setup.py using python interpreter.
You can start the server manually - any errors will echo on the terminal. The windows app seems touchy on timing - this allows the server to take as much time as needed to start up.
Assuming you installed version 3 into "p:\pgAdmin 4" run the following commands"
p:
cd "\pgAdmin 4\v3\web"
set PYTHONPATH=P:\pgAdmin 4\v3\venv\Lib;P:\pgAdmin 4\v3\venv\DLLs
python pgAdmin4.py
When I run that I get the following output:
Starting pgAdmin 4. Please navigate to http://127.0.0.1:5050 in your browser.
I ran into this today even though the service was running in Windows 10. I just stopped the service, gave it a few seconds, and restarted it. I was able to connect with pgAdmin 4.
In my case the problem was solved by restarting the postgresql service.
Windows-> Service -> find for postgreSQL -> Stop and then Start
I try to start opensshd app by following command line: net start opensshd but i encounter below message after press enter in CMD:
The OpenSSH Server service is starting.
The OpenSSH Server service could not be started.
A system error has occurred.
System error 1067 has occurred.
The process terminated unexpectedly.
i install openssh.
please Help Me!
I got the similar problem that i cannot startup the "OpenSSH SSH Serve" service after following the instructions in https://hostadvice.com/how-to/how-to-install-an-openssh-server-client-on-a-windows-2016-server/
I later on found out that this is the security problem in the C:\ProgramData\ssh\ssh_host*key files. All the key files in this folder should ONLY be owned by following 2 system users:
BUILTIN\Administrators
NT AUTHORITY\SYSTEM
In the Powershell under the C:\ProgramData\ssh folder, issue following command can list out the owners of the file ssh_host_dsa_key:
PS C:\ProgramData\ssh> icacls .\ssh_host_dsa_key
.\ssh_host_dsa_key BUILTIN\Administrators:(F)
NT AUTHORITY\SYSTEM:(F)
xxdomain\otheruser:(M)
Successfully processed 1 files; Failed processing 0 files
Obviously we need to remove the user "xxdomain\otheruser" from the owner list
Resolution
Updated on Nov 25, 2019: Found out that the OpenSSH-Win64.zip file already contained a powershell script: FixHostFilePermissions.ps1
What you need to do is to run following inside the powershell:
cd 'C:\Program Files\OpenSSH-Win64'
.\FixHostFilePermissions.ps1
And press 'Enter' for each question to update the permission.
just write this command in PowerShell
cd 'C:\Program Files\OpenSSH-Win64'
.\FixHostFilePermissions.ps1
then press enter .
I got this error, and it turned out in my case to be an error I'd made editing sshd_config, so be sure to check this. Spent ages trying to diagnose this.
Hope that saves someone some pain.
I got the same error by installing OpenSSH on Windows 7...
Open "services.msc" and try to start the service from there.
If it still doesn't work then you can try to follow the steps in this tutorial:
http://www.techpaste.com/2015/06/windows-ssh-server-setup-and-configuration/
One important thing: Try to download an older version of OpenSSH
Download Link: http://www.mls-software.com/opensshd.html#botpage
(I recommend you the version "setupssh-7.3p1-2")
Hope it works
Cheers
For me the solution was to download and install an MSI from this github repo
I am follwing this tutorial: I am using 64-bit Windows 7 computer.
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/
I have installed MongoDB and starts the MongoDB file from the command prompt. Then I get the following error message:
Unable to create/open lock file: \data\db\mongod.lock
I don't know how to solve that problem.
Delete the mongod.lock file in the /data/db folder
Restart mongodb
I was experiencing a similar problem and i noted that some MongoDB processes were running in the background when i opened the task manager. so after i terminated the tasks and went to the mongod.lock file i was now able to delete it.
I have been googling for the past few hours but I simply can't get my apache on wamp to start. My skype isn't running, and the test port 80 shows it isn't being used by anything. Before this happened, I was trying to add a new vhost, but now I have reverted back all of the files where I made changes. Anyway to debug why apache won't start?
Clicking on start/resume service for apache doesn't show any errors either.
Also just in case, I am running Win7 64bit
If you have an issue in the httpd.conf or any files included by it there are a couple of ways to find out what the problem is
First look at your Windows Event Viewer. Click on the Windows link in the menu on the left, and then submenu Applications.
Look for messages from Apache with the red error icon.
Secondly, open a command window, then CD into \wamp\bin\apache\apache2.x.y\bin, replace x,y with your actual version.
Now you can run this command to get Apache(httpd) to validate the httpd.conf file.
httpd.exe -t
This should give errors with line numbers related to the http.conf file.
It stops on the first error, so you will have to keep running it and fixing the error and then run it again until it gives the all OK message.
Use apaches startup debug tool from command: httpd.exe -e warn
press Win+R
type cmd and press enter
goto directory which contains your apache httpd.exe file. for example if your wamp is installed in e:\wamp type cd /d e:\wamp\bin\apache\ApacheX.X.X\bin in cmd and press enter.
type httpd.exe -e warn (or httpd.exe -e debug for more details) to see error message about problem which is prohibiting apache to start.
That is what I did and it helped me to find out what my Apache-PHP needed:
C:\Users\Admin>cd C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\apache\apache2.4.9\bin>httpd -t
Syntax OK
C:\wamp\bin\apache\apache2.4.9\bin>httpd -k start
[Thu Apr 23 14:14:52.150189 2015] [mpm_winnt:error] [pid 3184:tid 112]
(OS 2)The system cannot find the file specified. : AH00436:
No installed service named "Apache2.4".
C:\wamp\bin\apache\apache2.4.9\bin>
The most simple solution:
Uninstall and reinstall WAMP (do not even try to set it up on top of existing installation - it would not help)
P.S.
If you wonder how did I get to this situation, here is the answer: I was trying to install WAMP and it throws me an error in the middle of installation saying:
httpd.exe - System Error
The program can't start because MSVCR110.dll is missing from your computer.
Try reinstalling the program to fix this problem.
OK
I got and installed Microsoft Visual C++ 2012 Redistributable from here http://www.microsoft.com/en-us/download/details.aspx?id=30679#
And it gave me the "dll" and the MYSQL started working, but not Apache.
To make Apache to work I uninstalled and reinstalled WAMP.
This solved the issue for me:
Right click on the WAMP system try icon -> Tools -> Reinstall all services
Go to C directory and then go to below mentiond path of you wamp server.
C:\wamp64\bin\apache\apache2.4.46\bin>
Then in Address bar enter "CMD" and press enter.that wil open the command prompt.
Now past below comman
httpd.exe -e warn
to see error message about problem which is prohibiting apache to start.
If you error is releated to port then
Right click on wamp server than on apache and then on httpd.confg,
Now search 80 and replace with 81 in that file and close and restart wamp
Invalid Command '80HostnameLookups' , perhaps misspelled or defined by a module not included in the server configuration
I got this error when I debug the issue (wamp server was not going online) by the procedure defined by #RiggsFolly. Just comment the line 80HostnameLookups Off by changing it to #80HostnameLookups Off.
This solution worked for me and apache starts running.Note:80HostnameLookups Off can be found on line 222 of httpd.conf file located in C:\wamp\bin\apache\apache2.4.9\conf
phpmyadmin.conf opened with apacheconf.exe and contents chained so you must do the following:
copy contents of phpsysinfo.conf [C:\wamp\alias]
paste into phpmyadmin.conf [C:\wamp\alias]
change Alias /phpsysinfo "c:/wamp/apps/phpsysinfo3.1.12/" to Alias /phpmyadmin "c:/wamp/apps/phpmyadmin4.1.14/"
change <Directory c:/wamp/apps/phpsysinfo3.1.12/ /> to <Directory c:/wamp/apps/phpmyadmin4.1.14/ />
its worked for me.
My solution was that 2 .dll files(msvcp110.dll, msvcr110.dll) were missing from the directory :
C:\wamp\bin\apache\apache2.4.9\bin
So I copied these 2 files to all these locations just in case and restarted wamp it worked
C:\wamp
C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\apache\apache2.4.9
C:\wamp\bin\mysql\mysql5.6.17
C:\wamp\bin\php\php5.5.12
I hope this helps someone out.
Sometimes it is Skype or another application "Holding" on to port 80. Jusct close Skype
My solution on Windows 10 was just to stop IIS (Internet Information Services).
If Apache is installed as a Windows service, any errors will show up in the Windows System event log. To view the System event log, navigate to Windows Administrative Tools->Event Viewer and open the System log in the Windows Logs folder. Or, you can see the same errors by running httpd.exe at the command line. In my case, httpd.exe is located here: C:\Bitnami\wampstack-5.6.26-2\apache2\bin.
If there is a problem with starting Apache, most likely the problem can be fixed by editing the httpd.conf file located in the \apache2\conf folder.
As already suggested, you can check the syntax of the httpd.conf file by running httpd.exe -t at the command line.
I found that the I had to
Change SetEnv PATH "C:\Bitnami\wampstack-5.6.26-2\apache2\bin;${PATH}" in httpd.conf
to
SetEnv PATH "C:\Bitnami\wampstack-5.6.26-2\apache2\bin;%PATH%"
I had the same problem. My port 80 was not in use.
After thorough research, all I did was to download Update for Universal C Runtime.
Once installed and my PC restarted, all was OK.
I was having the same problem, the mysql service was starting but not the apache service, the main problem about that is one of your virtual hosts isn't config. correctly, all i did was deleted the virtual host that i created "D:\wamp\bin\apache\apache2.4.23\conf\extra\httpd-vhosts, restarted all services apache service started working correctly and so i just went to localhost and added a virtual host automatically and so it worked!!
I was having same problem.
I followed this steps, problem solved.
run command line (CMD) with Administrator Permission.
cd c:/wamp64/bin/apache/apache2.4.27/bin
httpd.exe -k uninstall
httpd.exe -k install
at last restart all services from wamp system tray icon
It turns out I didn't have Microsoft visual c++ installed, installing it solved the problem for me.
If you have Microsoft Visual Studio running at time of running, try to disconnect it and try again
