Oracle DB link latency / performance issues on Solaris
Last updated on JANUARY 02, 2018
Applies to:Solaris Operating System - Version 10 3/05 to 11.3 [Release 10.0 to 11.0]
Information in this document applies to any platform.
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.
Nothing really changed, although it is likely the overall database workload had increased somewhat.
