Is there any ways to check if oracle client has been installed.
Currently Im using OracleHome function in my application in order to check if oracle client has been installed because this function raise TStringList exception when it hasnt been installed.
Im just looking for standard way in doa if it exists.
You can call the InitOCI function in the OracleCI unit. If it raises an exception, the OCI (Oracle Call Interface) library could not be loaded, and the error message or the exception will indicate what went wrong.
