Slow connection to sqlplus on IBM AIX (Doc ID 1554598.1)

Last updated on JUNE 14, 2021

Applies to:

Oracle Database - Enterprise Edition - Version and later
SQL*Plus - Version and later
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Database Exadata Express Cloud Service - Version N/A and later
IBM AIX on POWER Systems (64-bit)


Below are the usual symptoms seen: 1.The connection using sqlplus is slow on a new installation. 2.The truss output shows the below delay:  truss -aefdD -o /tmp/test_conn.txt sqlplus '/as sysdba'

 When connecting using sqlplus /nolog" there is a delay, after which the connection to database using "conn /as sysdba" is faster. This proves the issue is with connecting to sqlplus and not with the database.



Nothing was changed in the configuration of OS.
