instantclient sqlplus not working
On AIX I've installed both instantclient_10_2 and instantclient_11 unzipping
basic-10.2.0.5.0-aix-ppc64.zip and sqlplus-10.2.0.5.0-aix-ppc64.zip for instantclient_10
and instantclient-basic-aix.ppc64-11.2.0.4.0.zip and instantclient-sqlplus-aix.ppc64-11.2.0.4.0.zip for instant client11
on both installation i created network/admin/tnsnames.ora
I set ORACLE_HOME , PATH on the proper installation user
but when I run sqlplus I get
Error 6 initializing SQL*Plus
Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
I've also performed chmod -R 755 $ORACLE_HOME
being an instant client $ORACLE_HOME/sqlplus/mesg doesn't exists.
How can I resolve?
