Applies to:Oracle Database - Enterprise Edition - Version 220.127.116.11.0 and later
Oracle Solaris on SPARC (64-bit)
- Running on SPARC, using either the SPARC T3, T4 or T5 chipset.
- Degraded performance.
- Waits on the 'log file sync' event appear in the Top Five Timed Foreground Events of the AWR report.
Potentially, an increase in workload volume may cause symptoms to manifest themselves more obviously.
