 sqlplus: error while loading shared libraries:

回答1:

The minimum configuration to properly run sqlplus from the shell is to set ORACLE_HOME and LD_LIBRARY_PATH. For ease of use, you might want to set the PATH accordingly too.

Assuming you have unzipped the required archives in /opt/oracle/instantclient_11_1:

$ export ORACLE_HOME=/opt/oracle/instantclient_11_1
$ export LD_LIBRARY_PATH="$ORACLE_HOME"
$ export PATH="$ORACLE_HOME:$PATH"

$ sqlplus

I did solve this error by setting

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME

yes, not only $ORACLE_HOME/lib but $ORACLE_HOME too.

回答3:

sudo sh -c "echo /usr/lib/oracle/12.2/client64/lib > /etc/ld.so.conf.d/oracle-instantclient.conf";sudo ldconfig

回答4:

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

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
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"
```

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.

回答6:

You should already have all needed variables in /etc/profile.d/oracle.sh. Make sure you source it:

$ source /etc/profile.d/oracle.sh

PS: this file's content looks like:

ORACLE_HOME=/usr/lib/oracle/11.2/client64
PATH=$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
export ORACLE_HOME
export LD_LIBRARY_PATH
export PATH

If you don't have it, create it and source it.

回答7:

You can try usage:

# echo "/usr/lib/oracle/12.2/client64/lib" > /etc/ld.so.conf.d/oracle.conf
# ldconfig

This problem are because oracleinstant client not configure shared library.

回答8:

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.
