Detailed Description and Symptoms
After an attempt to load a new solution jar file to the Automic DB and restart the RA FTP Agent, these messages are written to the RA Agent log:
U2013310 Failed to load RA Agent.
U0003620 Routine 'UCEX_R' forces trace because of error.
U0003450 The TRACE file was opened with the switches '0000000000000001'.?
Running the agent from the command line with a nohup command might throw an error like: java.lang.NumberFormatException: For input string: "&01".
Locate the RA Agent's trace log (RA_TRACE_xx.TXT) and examine for this message in "STACK TRACE" section:
java.lang.NumberFormatException: For input string: "version.txt"
This was a very unusual issue that does not occur often. The solution is to delete everything under the "cache" directory, the directory is located in the root RA Agent directory.
<baseDirectory>/cache <--- Delete everything under this directory, DO NOT delete the directory itself.
