silent installation of 11.1.0.7 on Linux

There are Oracle installations that simplier to do in command line
and one of them is patchset installation.

To start it I used ORACLE_HOME and ORACLE_HOME_NAME
in addition to usual -silent -responseFile options

./runInstaller -silent \
-responseFile /u02/install/patch/Disk1/response/patchset.rsp \
ORACLE_HOME="/u03/app/oracle/product/11.1.0/db_1" \
ORACLE_HOME_NAME="OraDb11g_home1"


But the execution failed with error:

SEVERE:Values for the following variables could not be obtained
from the command line or response file(s):
  METALINK_USERNAME(MetaLinkUsername)
Silent install cannot continue

Well, if it is not provided why not to use just null value. For some reason
installer did not want to do it and I added METALINK_USERNAME
(together with METALINK_PASSWORD) defined to empty string:

/u02/install/patch/Disk1> ./runInstaller -silent \
-responseFile /u02/install/patch/Disk1/response/patchset.rsp \
ORACLE_HOME="/u03/app/oracle/product/11.1.0/db_1" \
ORACLE_HOME_NAME="OraDb11g_home1" \
METALINK_USERNAME="" METALINK_PASSWORD=""


And the installation went further but stopped asking me:

You may not have enough space on your drive for a successful install.
Do you still want to continue?

Funny but I tried to answer "y", "Y", "YES" but it was failing with
"-bash: n: command not found". And then I checked the log
of installation: "INFO: Installation cannot continue. To Ignore Disk Warning, please use "-ignoreDiskWarning" command line option" was there.

I added -ignoreDiskWarning and was able to install patchset without problems
and questions

./runInstaller -silent\
 -responseFile /u02/install/patch/Disk1/response/patchset.rsp \
ORACLE_HOME="/u03/app/oracle/product/11.1.0/db_1" \
ORACLE_HOME_NAME="OraDb11g_home1" \
METALINK_USERNAME="" METALINK_PASSWORD="" \
-ignoreDiskWarning

Another thing that is worth to mention that root.sh script generated
during silent installation also has parameter not to show output:

grep -i silent /u03/app/oracle/product/11.1.0/db_1/root.sh
OUI_SILENT=true
...


With TRUE value it won't show anything on a screen during execution
but change to FALSE will provide the output as usual.


Have a good day!
