Trying to install Oracle 9.2.0.4 On Linux Redhat 3 seeing error : -

Error: You do not have sufficient privileges to write to the specified path. in component DatabaseConfiguration Assistant

From the installActions log file:

Please specify a unique SID.
Setting value of s_OPSNodeInfoString to
Setting value of s_oidRegister to *Protected value, not to be logged*
Setting value of s_launchFile to /u01/app/oracle/product/9.2.0.4/bin/dbca
Setting value of s_instLaunchFile to /u01/app/oracle/product/9.2.0.4/assistants/dbca/dbca.sbs

Calling query generalQueries2.2.0.7.0 getenv

name = ORACLE_BASE
Query returned :
Setting value of s_mountPoint to /oradata

This is because ORACLE_BASE is not set, hence instead of trying to write to $ORACLE_BASE/oradata , the OracleUniversal Installer (OUI)is trying to write to/oradatafor which it does not have the privilege.

To implement the solution, please execute the following steps:
Clean up the failed installation
Set ORACLE_BASE to the appropriate PATH and install again
