Description
The TNS_ADMIN environment variable must not be set.
There must not be a tnsnames.ora file in the /etc or /var/opt/oracle
directories.
If you are installing the OracleAS Infrastructure in a Real Application Clusters
environment, you need to set this environment variable to point to a file that
describes the locations of your raw partitions.
The installer checks that you are not installing Oracle Application Server in a
cluster file system (CFS).
The installer runs this check only if you are expanding a middle tier or if you are
reinstalling Oracle Application Server in the same Oracle home. The installer
checks that these directories are writable by the operating system user running the
installer:
ORACLE_HOME/sysman/emd

ORACLE_HOME/sysman/config
■
ORACLE_HOME/sysman/webapps/emd/WEB-INF/config
■
The installer runs this check only if you are expanding a middle tier or if you are
