hi everyone,I tried hard to install oracle-11g-R2 in my CentOS5.5,during the install,I did all my job step by step as this article says:
Q1: when I 'su oracle' and 'sqlplus /nolog'
,it said:"sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
".The article has a solution for this problem:"Solution: Install libaio and libaio-devel packages. If packages already installed and error still occurs try execute "ldconfig" as root.
Then i executed "ldconfig" as root ,and run "sqlplus /nolog",it occured another problem:"SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory".
Oh,those things drive me crazy!!
