ORA-1017 from powershell script only

[PeterLA2]

Hi all,

old topic maybe, but with a new twist...

I have an SAP system with an oracle database on windows that I can connect to from the command line as sidadm just fine:

sqlplus / as sysdba

SQL*Plus: Release 19.0.0.0.0 - Production on Fri May 9 17:52:12 2025
Version 19.14.0.0.0

Copyright (c) 1982, 2021, Oracle. All rights reserved.

Connected to:
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production
Version 19.14.0.0.0
SQL>

If I try the same from a powershell script, I am getting ora-1017:

$AdminDomain = 'host'
$AdminUsername = 'sidadm'
$AdminPassword = 'password'

$credential = New-Object System.Management.Automation.PSCredential @(($AdminDomain + "\" + $AdminUsername), (ConvertTo-SecureString -String $AdminPassword -AsPlainText -Force))

Invoke-Command -Credential $credential -ComputerName localhost -ScriptBlock { get-childitem env:
sqlplus -S / as sysdba }

Resulting output:

ERROR:
ORA-01017: invalid username/password; logon denied

a tnsping with invoke-command shows that I am connecting to the correct host and database.
Enabling audit trail creates no audit file for failed logins.
Enabling client trace in sqlnet.ora writes a trace file whenever sqlplus is invoked from the command line but not with invoke-command from powershell.

Any ideas ?

When you are logging on with SQLPLUS, you use the OPS$ connection method. With the POWERSHELL script, you are using username/password combination.
