&#x20;`mkdir lib`&#x20;

And move the instant client files into the lib folder, If the soft links are not copied or pointing right folder, please remove the soft links and create new soft links within this lib folder.

**Note:** After unzipping we are expecting all the files will be in the lib folder, so please move the files and remove previous soft links and create it again within the lib folder.

**Example to create soft links:**

`ln -s libocci.so.21.1 libocci.so.19.1`

**For Linux:** Open the .bash\_profile and add the following export lines,

`export ORACLE_HOME="Instant client home path"`&#x20;

`export LD_LIBRARY_PATH="Instant client lib path"`

&#x20;                                                     OR

You can add the export *"LD\_LIBRARY\_PATH=Instant client lib path"* in the start.sh file which is located cloudio 4.o server folder.
