Answer 1

On Oracle's own Linux (Version 7.7, PRETTY_NAME="Oracle Linux Server 7.7" in /etc/os-release), if you installed the 18.3 client libraries with

sudo yum install oracle-instantclient18.3-basic.x86_64
sudo yum install oracle-instantclient18.3-sqlplus.x86_64

then you need to put the following in your .bash_profile:

export ORACLE_HOME=/usr/lib/oracle/18.3/client64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME

in order to be able to invoke the SQLPlus client, which, incidentally, is called sqlplus64 on this platform.

Answer 2

Could you please check if LD_LIBRARY_PATH points to the oracle libs

Answer 3

I know it's an old thread, but I got into this once again with Oracle 12c and LD_LIBRARY_PATH has been set correctly. I have used strace to see what exactly it was looking for and why it failed:

 strace sqlplus /nolog

sqlplus tries to load this lib from different dirs, some didn't exist in my install. Then it tried the one I already had on my LD_LIBRARY_PATH:

open("/oracle/product/12.1.0/db_1/lib/libsqlplus.so", O_RDONLY) = -1 EACCES (Permission denied)

So in my case the lib had 740 permissions, and since my user wasn't an owner or didn't have oracle group assigned I couldn't read it. So simple chmod +r helped.

Answer 4

It means you didn't set ORACLE_HOME and ORACLE_SID variables. Kindly set proper working $ORACLE_HOME and $ORACLE_SID and after that execute sqlplus /nolog command. It will be working.

Answer 5

@laryx-decidua: I think you are only seeing the 18.x instant client releases that are in the ol7_oci_included repo. The 19.x instant client RPMs, at the moment, are only in the ol7_oracle_instantclient repo. Easiest way to access that repo is:

yum install oracle-release-el7

Answer 6

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"
