You are installed “Oracle Application Diagnostics For Java” (AD4J) but during “dbagent” configuration on linux receive error message “uuencode not installed“. If there are no any uuencode rpm package, then question is — where to take this utility ?

Full text of error:

===========================================================
ERROR: uudecode not installed or not in PATH. Please install it into your PATH and try again.
===========================================================

To resolve this issue install ‘sharutils’ (sometimes ‘shar-utils’) rpm package (in case of redhat: ‘up2date sharutils’).
After that you will get ‘uuencode’ on you server and it will be possible to continue you installation.

===========================================================
[oracle@test ~]$ which uuencode
/usr/bin/uuencode
[oracle@test ~]$
==========================================================

For more information check Uuencode and Sharutils.

bye!

In this case the problem was that backup originally was done from Oracle 64bit, but restored to Oracle 32bit. To resolve this issue, simply switch your database to 32bit with help of Metalink NOTE [ID 62290.1] — Changing between 32-bit and 64-bit Word Sizes.

Good luck!
