Answer 1

PERMISSIONS: I want to stress the importance of permissions for "sqlplus".

1. For any "Other" UNIX user other than the Owner/Group to be able to run sqlplus and access an ORACLE database , read/execute permissions are required (rx) for these 4 directories :

   $ORACLE_HOME/bin , $ORACLE_HOME/lib, $ORACLE_HOME/oracore, $ORACLE_HOME/sqlplus

2. Environment. Set those properly:

   A. ORACLE_HOME (example: ORACLE_HOME=/u01/app/oranpgm/product/12.1.0/PRMNRDEV/)

   B. LD_LIBRARY_PATH (example: ORACLE_HOME=/u01/app/oranpgm/product/12.1.0/PRMNRDEV/lib)

   C. ORACLE_SID

   D. PATH

    export PATH="$ORACLE_HOME/bin:$PATH"
