sqlplus: cannot execute binary file
After sourcing the environment for database 10gR2. Getting error like below.
export ORACLE_SID=SID
export ORACLE_HOME=ORACLE_HOME_PATH
export PATH=$ORACLE_HOME/bin:$PATH:.
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$PATH:.
sqlplus "/as sysdba"
sqlplus: cannot execute binary file
Any help would be appreciated
