Solaris Cluster How to Enable Method and/or System Coredumps for Cluster Methods That Timeout
(Doc ID 1019001.1)
Last updated on FEBRUARY 01, 2019
Applies to:Solaris Cluster - Version 3.2 and later
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)
If an Solaris Cluster Resource Group Manger (RGM) method callback times out, the method's process group is killed by a SIGTERM signal. If the process tree does not exit within ten seconds, a SIGKILL is executed.
- Solaris Cluster 3.2 / Solaris 5.10 and <SunPatch 144221-05> or later
(<SunPatch 144220-05> for Solaris 5.9) or
- Solaris Cluster 3.3 / Solaris 5.10 and <SunPatch 145333-04> or later or
- Solaris Cluster 3.3u1 or later,
the default behavior for the RGM is that method core dumps are not generated when a method times out, however, system core dumps are generated when a node is rebooted by the RGM due to a resource's Failover_mode property being set to HARD and the resource method being stuck in the kernel and failing to exit after a SIGKILL.
Note: x86 patches are:
- 3.2 Solaris 10x86 : <SunPatch 144222-05> or later
- 3.3 Solaris 10x86 : <SunPatch 145334-05> or later
