ORA-12547: TNS:lost contact

I was getting the following error while trying to connect to database locally as a different user:

oracledbtst: error while loading shared libraries: libskgxp11.so: cannot open shared object file: No such file or directory
ERROR:
ORA-12547: TNS:lost contact

I was told that the Oracle Software from which the database was running was copied from another server.

Hence, to resolve it, the following was done:

In order to fix it, this is what I did:
1. Stopped the database and the listener running from the home of the database.

2. Gave correct permission to $ORACLE_HOME/bin/oracle:

$ chmod 6751 $ORACLE_HOME/bin/oracle

3. Relinked the Oracle binary as follows since the database version was 11.1 on Linux

$ cd $ORACLE_HOME/bin
$ relink all

4. Started my database and the listener

5. Tested the connection and it worked without any errors.
