The internal parameters bd_hb_interval and bd_hb_interval_low_platforms are not handled correctly and a different value is registered against the high availability (HA) system. This causes the system to have faster than expected failovers. Also, when bypass asm is turned on and a bigstart restart asm was applied, a failover happens.
A failover happens.
Two possible conditions: 1. An internal parameter is configured for the timeout to the HA system. When ASM does not send a lifesign to the HA system for 10 seconds (instead of the configured time) 2. bypass asm is internal parameter is applied and a bigstart restart asm happens.
This issue has no workaround at this time.
This release fixes internal parameter processing for the high availability lifesign timeout.
