How to run a SQL Plus script in PowerShell

Question

I am trying to log in to the the Oracle DB using PowerShell and run a script called \"C:\\Users\\Administrator\\Desktop\\oracle\\OracleCleanTest.sql\", When I execute the PS

Answer 1

I use the call operator, &, as Keith Hill has suggested with the question, How to run an EXE file in PowerShell with parameters with spaces and quotes.

& 'path\sqlplus.exe' 'system/password@dbase as sysdba'

I placed the username, password in quotes due to the spaces.

To start a script, I add another parameter as follows:

 & 'path\sqlplus.exe' 'system/password@dbase as sysdba' '@my_script.sql'

If you are receiving the ORA-12154 error, and you know that other users have established connections (which implies that the database listener is running properly); I would then examine if SQL*Plus can find my tnsname file.

My first task would be to see if I can tnsping as follows in Windows cmd.exe:

tnsping orcl

It will confirm that a connection can (or can not be established).

If it cannot, I would check to see if the environment variable, ORACLE_HOME, is set. SQL*Plus uses this to find tnsname.ora file.

If it is not set, I would execute this statement in PowerShell (to establish this environment variable):

[Environment]::SetEnvironmentVariable("ORACLE_HOME", "C:\app\Administrator\product\11.2.0\client_1" , "User")

Next, I would retry to tnsping (identified above).

Once successful, I would re-try to execute the script running command above.
