 - TIP:
 	- If you don't have alternate hosting URL then, you can download the tar/zipped file of clidriver from the [IBM Hosted URL](#downloadCli) and can set the **IBM_DB_INSTALLER_URL** environment variable to the downloaded "tar/zipped clidriver's" parent directory path. No need to untar/unzip the clidriver and do not change the name of downloaded file.

+- HOW:
+	- On distributed platforms, Set **DOWNLOAD_CLIDRIVER** environment variable to `true` to force downloading of clidriver from IBM hosted URL. Never set DOWNLOAD_CLIDRIVER on z/OS system.
