sqlplus：加载共享库时出错：libsqlplus.so：无法打开共享对象文件：没有这样的文件或目录

Question

Please suggest a solution for solving this issue?? While giving the command:

sqlplus /nolog

the error that occurred:

 sqlplus: error while loading shared libraries:
 libsqlplus.so: cannot open shared object file: No such file or directory

Answer 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

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

Answer 3

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.

Answer 4

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

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

The 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.

Answer 5

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"

Answer 6

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 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.

Answer 8

您能否检查一下 LD_LIBRARY_PATH 是否指向 oracle 库

Answer 9

On Ubuntu Server 20.04 and using instant client version 19.10.0.0, I used alien to install the rpm package. I got this error when I just used the -i option. However when, I added -c I did not have this issue. from the man page for alien:

-c, --scripts
Try to convert the scripts that are meant to be run when the package is installed and removed. Use this with caution, because these scripts might be designed to work on a system unlike your own, and could cause problems. It is recommended that you examine the scripts by hand and check to see what they do before using this option.

So it seems the correct configuration (in 19c) or the environment variables (in earlier versions) are set in these scripts which are not generated unless you run alien like this. (Thanks @Christopher Jones for correcting me on this)

sudo alien -i -c BasicPackage.rpm
sudo alien -i -c SqlPlus.rpm

Answer 10

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 11

Don't forget

apt-get install libaio1 libaio-dev

or

yum install libaio

Answer 12

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 13

@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
