On the application server running Oracle Empirica Signal 9.2.2, start a command shell.

1. As the non-privileged user, on the application server running Oracle Empirica Signal 9.2.2, start a command shell (for example, Putty).
2. Create a temporary directory <Signal9221> (for example, /u01/stage/Signal9221), and unpack ESI_9.2.2.1.zip into it.
3. In the temporary directory, open the file update_Signal.sh and verify that directory /u01/stage/Signal_Install (hereafter referred to as <INSTALL_DIR>), specified in the file, exists.
   Change the script to point to the correct location if the actual <INSTALL_DIR> location is different.
4. From the temporary directory, give the shell script execute permissions and run it:
   $ chmod +x update_Signal.sh
   $ ./update_Signal.sh

   Verify that the script prints Completed and that there are no errors.

5. Verify that there is a backup copy of <INSTALL_DIR> (for example: Signal_Install.9_2_2_0_124_bkp).
