silent installation of agent 10.2.0.5

I recently installed agents 10.2.0.5 on SunOS (SPARC) 5.9 and Linux x86-64
silently and noted the same problem during secure command - the screen
had being erased if password was not sent as a parameter
in emctl secure agent command.

If a password is there - everything is fine, agent was secured (there is less
information about completion in output for that version of agent)

Oracle Enterprise Manager 10g Release 5 Grid Control 10.2.0.5.0.

Agent is already stopped...   Done.
Securing agent...   Started.
Securing agent...   Successful.

But I have to mention that I spent several hours trying
to install agent silently (on Solaris 9) and it was failing:

Checking installer requirements...

Checking operating system version: must be 5.8, 5.9 or 5.10.    Actual 5.9
                                     Passed

Checking Temp space: must be greater than 250 MB.   Actual 14145 MB    Passed
Checking swap space: must be greater than 500 MB.   Actual 16220 MB    Passed

All installer requirements met.

Preparing to launch Oracle Universal Installer
from /tmp/OraInstall2009-04-30_01-11-35AM.
Please wait ...
Please specify a Unique Oracle Base directory, 
or remove previously installed products and their directories. 
Directory name should contain only valid alphanumeric characters, 
including '_', or '.' characters.

But the directory /opt/app/oracle/agent10g did not even exist there
and there was no entry about that oracle home neither in inventory.xml
nor in oratab

Resolution was simple - I created a copy of original response file,
removed comments and empty rows, changed parameters accordingly
the environment and it worked!. The installation had been completed,
root.sh had been executed(new requirement came with 10.2.0.5)
and everything was completed.

Worth to mention that port should be http for OMS connection
even if OMS is secured (1159 by default)

I hope your installation will go smooth and quick

Have a good day!
