Oracle DB link latency / performance issues on Solaris 11.1 (Doc ID 2072384.1)

Last updated on JULY 29, 2016

Applies to:

Solaris Operating System - Version 11.1 to 11.3 [Release 11.0]
Information in this document applies to any platform.

Symptoms

Oracle Databases moving data between three different DB instances with the Oracle "DB link" feature reported high levels of latency - of 70-100 milliseconds vs. the expected 5-10 milliseconds.

This impacted overall database performance and resulted in end-user complaints about response times. 

Changes

Nothing really changed, although it is likely the overall database workload had increased somewhat.
