Why is user environment variable Path invalid in windows cmd? - path

I often set java in system environment variable, which will make it accessible in windows cmd, but people won't always have admin access on their computer. When I set the Path environment variable under a specific account. I was not able to use java in windows cmd even if I log in as that account?
Why is it so? And how can I set append any thing to Path permanently without using admin access?
C:\Users\xxx>cygwin
'cygwin' is not recognized as an internal or external command,
operable program or batch file.

My bad, I put cygwin folder under my C:\cygwin, which will make it admin access. After I change the user control to full, it is able to load the cygwin.
So namely,
1. Put admin access program (like C:\Program Files) under your system variable
2. Put local access program (lizhi C:\users\xxx) under your user account variable.
Then it will work as expected.
Thanks

Need Help understanding how PATH works with Windows 7

I am trying to add to the PATH via the Environment Variable settings windows for python.exe.
I have read the instructions using SetX from the March 3, 2012 discussion about this issue and am worried I will make a mess of my machine, so want to stick with the GUI process.
The directory path is C:\Users\Paul\AppData\Local\Programs\Python\Python37\python.exe.
That is a copy from the addition I made in the System Variables section of the Environment Variables window.
I have labelled the Variable Name as "Python", no quotation marks.
I have checked the path, and it looks good to me, and have rebooted the computer. But I still get the
'python.exe' is not recognized as an internal or external command, operable program or batch file.' error in every directory expect if I am specifically in the Python37 directory.
Any idea what I am doing wrong?
The path environment variable contains one or more paths, separated by semicolons. When you try to execute a command in cmd.exe it checks each path listed in the path variable in order of first to last until it finds the executable or runs out of paths to check.
You can experiment without making permanent changes to your system first. Run cmd.exe and type
set path=%path%;C:\Users\Paul\AppData\Local\Programs\Python\Python37
Running python.exe should now work in any directory in this cmd.exe window.
Unlike other environment variables, path is special and is a merged value from the system and user variables. Since you installed python just for yourself you might as well just use a user variable.
In the system properties where you edit environment variables, if there is no path user variable, create one and set it to C:\Users\Paul\AppData\Local\Programs\Python\Python37 or if it already exists, append ;C:\Users\Paul\AppData\Local\Programs\Python\Python37.
In newer versions of Windows 10 the UI is different and you don't have to add the semicolon because it lets you edit them as separate entries.

Why is my WSL2 enviornment referencing Java folder outside its virtual environment?

When I start my development rails server I get this following message first. To my knowledge WSL2 is a virtual environment.
I would have expected it to now reference a Java directory that resides on my Windows host. Is this likely something I carried over in the project from when I was using WSL1? How would I safely correct this?
/home/daveomcd/.rbenv/versions/2.6.1/lib/ruby/gems/2.6.0/gems/railties-6.0.3.2/lib/rails/app_loader.rb:53:
warning: Insecure world writable dir /mnt/c/Program Files (x86)/Common Files/Oracle/Java/javapath
in PATH, mode 040777
I experienced the same problem when trying to fix the slowness of WSL2. The recommended solution was to move the files from the mounted NTFS drive to the root ext4 filesystem (using \\$wsl\<distroname>), so I did that.
I set up /etc/wsl.conf as below:
# Enable extra metadata options by default
[automount]
enabled = true
root = /mnt/
options = "metadata,umask=0033"
mountFsTab = false
[interop]
enabled = true
appendWindowsPath = true
And ran rails bundle to update dependencies.
Also make sure that your file permissions and owner settings are updated. Hope it helps.
Sorry, I'd love to make this more of a comment to see if I'm on the right track before committing to an answer. However, since there's too much info here for that, I'll make an attempt at getting you an answer here.
While it is a virtual environment, by default WSL provides several "Windows Interop" features that allow it to:
automatically mount Windows drives in /mnt/{c,d,...}
append the Windows path to the Linux path
run Windows executables inside Linux
share Windows environment variables with Linux (although this is not something that happens by default)
I can't be sure (long, long time since I've used Rails), but it looks like something in the app_loader.rb is checking permissions on Java directories in the path. It may be using some logic like "check each path entry and look for a java or java.exe there. If found, check permissions." Or something like that. That means that (2) and (3) above may be confusing it.
You can see this in action with which java.exe, which will likely return a Windows path. Or run notepad.exe, which will launch the Windows Notepad executable from within Linux/WSL (magic! 😉).
These are both very useful features, so I hate to disable them completely, but it's the easiest way to figure out if that's the problem. Create a /etc/wsl.conf with the following contents:
[interop]
enabled=false
appendWindowsPath=false
Exit your WSL instance and then:
(from PowerShell, CMD, or Windows Start) Run wsl --list --verbose to see the name of your distribution (most likely Ubuntu)
Likewise, run wsl --terminate <distro> to terminate that distribution.
Restart your WSL instance
Try running /mnt/c/Windows/system32/notepad.exe (assuming a normal C:\Windows installation) (should fail, since interop is disabled)
Try which notepad.exe (should fail, since the Windows path should no longer be appended to the Linux path)
Try to start your Rails dev server again - Might work (might not, I could easily be wrong about the root-cause here)
If it does work, then you can try to correct the situation with several less invasive methods than disabling those features entirely:
If you plan on only using WSL for your development, then you could remove the Windows JDK.
Or at least remove the Windows JDK from the PATH in Windows.
Or, if you want to keep it installed and in the Windows path, you could have a shell startup file (e.g. .bashrc) that removes it from the path only in WSL. I'll point you to this question which contains multiple techniques for doing so.
Or you could keep the appendWindowsPath=false in your /etc/wsl.conf but then add back in the paths you want manually in your startup config.

How to install WebLogic AdminServer and NodeManager as windows service?

I am trying to install Weblogic adminserver as windows service but getting "Input too long" error while executing the install script.
I have struggled a lot in this issue and finally got the way to register AdminServer and Nodemanager as windows service for Weblogic. Below are the steps and issues faced with the progress:
To register weblogic AdminServer as windows server first need to create a script which will contain values like oracle home, java home etc. Below is the script I have used to install the service:
`
echo off
SETLOCAL
set MW_HOME=C:\Oracle\Middleware\Oracle_Home
set DOMAIN_NAME=osb_domain
set USERDOMAIN_HOME=C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain
set SERVER_NAME=AdminServer
set WL_HOME=C:\Oracle\Middleware\Oracle_Home\wlserver
set PRODUCTION_MODE=true
set JAVA_OPTIONS=-Dweblogic.Stdout="%USERDOMAIN_HOME%\stdout.txt" -Dweblogic.Stderr="%USERDOMAIN_HOME%\stderr.txt"
set WLS_USER=weblogic
set WLS_PW=Password123
set MEM_ARGS=-Xms1024m -Xmx1024m
call "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain\bin\setDomainEnv.cmd"
call "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\installSvc.cmd"
ENDLOCAL
`
By running this script I was not even able to install the windows service as it was throwing " Input is too long" error and the reason is windows char limitations. You might get confused by classpath and will try to resolve classpath but
the issue is with JAVA_OPTIONS values which is set by SetDomainEnv.txt is creating this issue.
I have modified the script like below and shorten the JAVA_OPTIONS values by calling SetDomainEnv.txt command just before setting JAVA_OPTIONS in the script.
This has overridden the lengthy value of JAVA_OPTIONS. Now I have succesfully installed the AdminServer as windows service.
`
echo off
SETLOCAL
set MW_HOME=C:\Oracle\Middleware\Oracle_Home
set DOMAIN_NAME=osb_domain
set USERDOMAIN_HOME=C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain
set SERVER_NAME=AdminServer
set WL_HOME=C:\Oracle\Middleware\Oracle_Home\wlserver
set PRODUCTION_MODE=true
call "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain\bin\setDomainEnv.cmd"
set JAVA_OPTIONS=-Dweblogic.Stdout="%USERDOMAIN_HOME%\stdout.txt" -Dweblogic.Stderr="%USERDOMAIN_HOME%\stderr.txt"
set WLS_USER=weblogic
set WLS_PW=Password123
set MEM_ARGS=-Xms1024m -Xmx1024m
call "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\installSvc.cmd"
ENDLOCAL `
Even the service is successfully installed, when I was starting it the service is stopped immediately and wasn't printing any logs as it was not connecting to AdminServer.
After a bit analysis I found that JAVA_OPTIONS values which I have overridden in my script is very much needed to invoke AdminServer.
I have run SetDomainEnv.txt in cmd prompt and copied thre JAVA_OPTIONS values.
As the service is already installed, I just copied the correct JAVA_OPTIONS values CMDLINE param in the windows service registry manually.
Server subsystem failed. Reason: A MultiException has 6 exceptions.
Server installed as Windows NT service with incorrect password for user weblogic. The password may have been changed since the server was installed as a Windows NT Service. Contact the Windows NT system administrator.
Note: No extra spaces or character is inserted in CMDLINE param.
Now everything is in place which is actually required to start the admin server. But when I start the service it is throwing some authentication error along with others in the adminserver.log file.
after a lot of analysis I found that is is not authentoication issue, the problem was with boot.properties file. boot. properties file was not read properly.
This answer is continuation of below one:
after a lot of analysis I found that is is not authentoication issue, the problem was with boot.properties file. boot. properties file was not read properly.
Now I would give some background- If the fusion middleware is installed as development mode the boot.properties files is created automatically inside Oracle_HOME\user_projects\domains\domainname\servers\AdminServer\security and if you look at this prop file you will find the password and username in encrypted mode.
If the fusion Middleware is installed as production Mode then everytime it will ask for password and username. to avoid this perform below steps:
manually create file under Oracle_HOME\user_projects\domains\domainname\servers\AdminServer\security\boot.properties like mention below:
username=weblogic
password=Password
Note: No spaces should be added and take care of file extension.
Now start weblogic from domain\bin\startWeblogic.cmd. This will encrypt you boot.properties file. check boot.proprties file if encrypted you are good to go.
Finally start the windows service whic is installed following above process. It should work fine.
=======================
About Node manager use installNodeMgrSvc from domain\bin. Again if you get input is too long error, you must shorten JAVA_OPTIONS and then carefully edit CMDLINE param in the windows registry.

Physical Path in Beanstalk

I'm totally newbie in Beanstalk. I'm developing a web application in which a sealed and black-box plugin is used. That plugin needs a physical path with full permission to use for cache.
Any solution?
You can use the .ebextensions files in the main project that will, for example, create a directory and change the access rights to it. It is not clear from your question how you install the plugin (e.g. is it a service that is loaded after the web application is installed or is it part of the web application).
Execute a command in the .ebextensions file such as in:
How to grant permission to users for a directory using command line in Windows?
You'll find a introduction into container customization in
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-windows-ec2.html
Be careful about the format of the files (ie. spaces, no tabs, the best is to edit it in a separate text editor). Experiment with simple commands first, so that you get the hang of how the commands are executed.
Note: The ebextensions commands are executed for each deployment, so your script should check if the directory exists already and only create it if it doesn't. Otherwise the execution will fail as you try to create a directory that exists already. In a second step you can add the permissions.

Installing local checks for Check_MK's agent

I'm trying to write local checks for a Check_MK instance on a computer with OMD installed. I don't have admin rights on this machine, so I work as an OMD site like this:
sudo omd su $MY_SITE
And, like my standard user, the site user does not have admin rights either.
In the Check_MK documentation for writing agent-based checks I find that I have two options for doing this:
Editing /usr/bin/check_mk_agent, which is impossible with the rights I have or
Creating a script in /usr/lib/check_mk_agent/plugins/, which is also impossible because this folder is only writeable to root.
When I run cmk --paths I see that there's a folder for "locally installed agents and plugins" at $MY_SITE_HOME/local/share/check_mk/agents/. This folder has a subfolder named plugins. If I put a script in there, however, its output doesn't show up when I run check_mk -d localhost. It is set to be executable and it does produce valid output, as far as I can tell:
<<<helloworld>>>
Hello world!
Am I putting the script in the wrong folder? Is it necessary to have admin rights in order to write agent based checks in Check_MK?
One way of doing this without admin rights would have been to edit main.mk to include include a new datasource program. I would have liked to have a local folder that was analog to /usr/lib/check_mk_agent/plugins/, but it seems that this is not possible. I ended up having one of our admins give me the rights to /usr/lib/check_mk_agent/plugins/.
