ORA-29740 Instance (ASM/DB) eviction on Solaris SPARC

(Doc ID 761717.1)

Last updated on JANUARY 05, 2013

Applies to:

Oracle Server - Enterprise Edition - Version to [Release 11.1]
Oracle Solaris on SPARC (64-bit)
***Checked for relevance on 24-Sep-2010***
Sun Solaris SPARC (64-bit)
DB or ASM instance using the option RAC.


o An instance is evicted of the cluster reporting the error:

Errors in file /u01/app/oracle/diag/asm/+asm/+ASM3/trace/+ASM3_lmon_27256.trc
ORA-29740: evicted by member 0, group incarnation 70

o The eviction was due to a IPC Send timeout reported in the alert log files for the instances:

IPC Send timeout detected.Sender: ospid 27268
Receiver: inst 1 binc 528748320 ospid 8728


IPC Send timeout detected. Receiver ospid 8728

o The Sender process reveals:

1. The process waited a few seconds (instead of 5 min):

GSIPC:KSXPCB: msg 0x3b0ad9218 status 32, type 43, dest 0, rcvr 1
GSIPC:KSXPCB: msg 0x3b0ad9218 send timed out inc 68 waited 2181325 usec
GSIPC:KSXPCB: dest_inc 68  sys_inc 68

- in this case the Sender waited 2 secs and declared the Send timeout.

2. The network segment was retransmitted only one time (CNT=1), but normally a process should resend the message several times before declaring a IPC Send timeout:

SKGXPCTX: 0x109a6b380 ctx
   sconno     accono   ertt  state   seq#   RcvPid   TotCredits  sent rtrans acks
seq=30893 len=200 accno=0x2aeb82ec start TS=0xa3c51d64 rt TS=0xa3c51d84 X CNT=1

- note that in some cases CNT can be 3 or 4.


Most of the situations reported have occurred on ASM environments and Solaris SPARC platform running and But the code where the error is produced is the same when we have ASM or DB instances running on RAC, thus this issue is not specific to ASM only.
