rtld: 0712-001 Symbol CreateIoCompletionPort was referenced $ORACLE_HOME/lib/libttsh12.so(), but a runtime definition of the symbol was not found.

Issue:

While connecting to Oracle Database from IBM AIX Operating system, the below errors were noticed.

$ Sqlplus ‘/ as sysdba’
Could not load program sqlplus:
rtld: 0712-001 Symbol CreateIoCompletionPort was referenced
from module /mnt/oracle/oradb/product/12.1.0.2/lib/libttsh12.so(), but a runtime definition
of the symbol was not found.
rtld: 0712-001 Symbol GetMultipleCompletionStatus was referenced
from module /mnt/oracle/oradb/product/12.1.0.2/lib/libttsh12.so(), but a runtime definition
of the symbol was not found.
rtld: 0712-002 fatal error: exiting.

 

Cause:

The Device Configuration for Input Output completion port might have not be configured as suggested by Oracle

 

Resolution:

Check the O/P of “lsdev|grep iocp”

$ lsdev | grep iocp
iocp0 Defined I/O Completion Ports

Change it to “Available”.

$ lsdev | grep iocp
iocp0 Available I/O Completion Ports
