Configure the shell environment for the CDB (orcl) and set the TWO_TASK variable to the PDB (pdborcl)
. oraenv
export TWO_TASK=pdborcl
sqlplus sys/password as sysdba
I got the link from here
The above instructions are vital to enable me install sample HR schema on my oracle 12c database(Home PC) for training on Windows 8.1.
I have tried running the commands using the prefix SET in windows power-shell and CMD (admin privileges) but no positive results.
I am aware that in order to set the TWO_TASK....I can achieve this by setting these parameters in windows environment or using CMD.
UPDATE WITH SOME CODE:
C:\WINDOWS\system32> SET oraenv
C:\WINDOWS\system32> SET export TWO_TASK=pdborcl
C:\WINDOWS\system32> SET sqlplus sys/1Ihavenone as sysdba
Set-Variable : A positional parameter cannot be found that accepts argument 'as'.

I am trying to access powershell from another user (user2), but at the same time I also want to access the resources of my main user (user1), I have a virtual environment, windows server 2022 and a windows 10 pro machine, in which I am doing the following:
Right click on the powershell icon > Run as another user, then I access user 2 to which I want to connect with their respective credentials.
Once this is done in powershell I execute the following:
runas /user:corp\user2 /netonly powershell
Then, I put the credentials again and navigate to the path of my main user(user1) and when I execute "ls", it gives me the following error:
ls : Access denied to path 'C:\Users\user1'.
At line:1 char:14

Hope you can help me out here. I've been playing around with some SSH authentication. I have no idea why this is happening, but now when I run a simple ssh-keygen command I get a response saying Access is denied. in addition to a pop-up that reads "This app can't run on your PC. To find a version for your PC, check with the software publisher".
I then tried running the ssh-keygen command in Powershell (as admin and as regular user) and got the following:
Program 'ssh-keygen.exe' failed to run: The specified executable is not a valid application for this OS platform.At
line:1 char:1
+ ssh-keygen
+ ~~~~~~~~~~.
At line:1 char:1
+ ssh-keygen
+ ~~~~~~~~~~
+ CategoryInfo : ResourceUnavailable: (:) [], ApplicationFailedException
+ FullyQualifiedErrorId : NativeCommandFailed
However, using ssh -V shows that it is installed:
OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2
I can still SSH fine into other devices, if that's of any relevant.
Any help would be very much appreciated here!
I'm trying to update the JVM Heap Size from Powershell by running this PS Script. It works on the local machine and persists as an env variable:
test.ps1
& cmd /c 'SETX _JAVA_OPTIONS "-Xms256m -Xmx256m"' | Write-Host
But when triggering this same test.ps1 script from a Remote Machine (through Nagios NRPE), the value of this env variable does not update though a success message is returned to the remote machine.
If running the Powershell command for setting the env variable (in a non-admin console), like below:
[Environment]::SetEnvironmentVariable("Test3", "test string", "Machine")
I'm getting this error:
Exception calling "SetEnvironmentVariable" with "3" argument(s): "Requested registry access is not allowed."
So how to trigger this PowerShell script remotely in an admin prompt mode?
You likely need to start the service that is running NRPE (NSClient++?) with an elevated account.
I was testing some nodejs server code and wanted to test the urls from windows power shell using the curl command. Some things to note here:
1. I have mingw and git bash installed in my system, and curl works fine from normal command prompt and git bash prompt.
2. Additionally I have downloaded the latest version of cURL from curl official web site and added the path of bin directory to the system's PATH variable.
But it seems like it is no good for power shell. However, powershell still recognizes cURL command regardless of additional cURL program or git bash present in the system or not. But it does not work as I expected it to be, for example I have tried the following command and:
Windows PowerShell

I also get the same output when I try it from git bash.
My question here is what do I need to do if I want everything to run smooth in windows power shell as well? I have done a little bit of searching on the net, and could not find much helpful resources. Also I have not any prior experience with windows powershell. Usually use linux as development environment.
It looks like you already have curl as an alias to Ivoke-WebRequest:
Invoke-WebRequest : A parameter cannot be found that matches parameter
name 'X'.
Try running remove-item alias:\curl and see if you now get the right curl being invoked. Alternatively, try by specifying the absolute path, i.e. c:\curl\curl.exe ....
Since I updated to PowerShell 4.0, an Alias was created to point to Invoke-WebRequest with the name of curl, so what I've done is I added my own alias to the curl.exe executable I want to use instead:
set-alias mcurl "C:\cygwin\bin\curl.exe"
Powershell 4.0
Get-Alias curl
CommandType Name ModuleName
----------- ---- ----------
Alias curl -> Invoke-WebRequest
My new Alias:
Get-Alias mcurl
CommandType Name ModuleName
----------- ---- ----------
Alias mcurl -> curl.exe
I'm running into a weird issue here.
I have a Windows server setup to allow SSH access via Cygwin.
The idea behind this is to allow me to remotely execute Powershell commands from one of my Linux boxes. Now, in the hopes of being secure while still allowing for automation, I did your typical ssh-copy-id to my designated account on that box. I then tried logging in via SSH keys... success! Now here's the weird part. I run my Powershell command:
powershell 'C:/cygwin64/scripts/add_email_address_to_distribution_list.ps1'
And get the following error message:
$ powershell
'C:/cygwin64/scripts/add_email_address_to_distribution_list.ps1'
Add-DistributionGroupMember : Value cannot be null. Parameter name:
serverSettings At
C:\cygwin64\scripts\add_email_address_to_distribution_list.ps1:2
char:28

+ CategoryInfo : NotSpecified: (:) [Add-DistributionGroupMember],
ArgumentNullException
+ FullyQualifiedErrorId : System.ArgumentNullException,Microsoft.Exchange.
Management.RecipientTasks.AddDistributionGroupMember
Now if I remove the pubkey from my account's .authorized_keys file, login with my usual password, and retry... the script works!
I'm stumped as to why authentication via password over SSH allows for the script to run successfully , while authentication via keys over SSH doesn't.
Any ideas?
EDIT:
Here's the script that's being run:
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010
Add-DistributionGroupMember -Identity some_distribution_list -Member user#domain.com
