GAB dynamic tunable parameters
Description and commandGAB parameter
Default: Disabled
This option defines the minimum number of nodes that can form the
cluster. This option controls the forming of the cluster. If the number
of nodes in the cluster is less than the number specified in the gabtab
file, then the cluster will not form. For example: if you type gabconfig
-c -n4, then the cluster will not form until all four nodes join the
cluster. If this option is enabled using the gabconfig -x command
then the node will join the cluster even if the other nodes in the cluster
are not yet part of the membership.
Use the following command to set the number of nodes that can form
the cluster:
gabconfig -n count
Use the following command to enable control seed port. Node can
form the cluster without waiting for other nodes for membership:
gabconfig -x
Control Seed port
Default: Disabled
This option controls our ability to halt (panic) the system on user
process death. If someone kills _had and _hashadow using kill -9, the
system can potentially loose high availability. If you enable this option,
then the GAB will PANIC the system on detecting the death of the
client process. The default behavior is to disable this option.
Use the following command to enable halt system on process death:
gabconfig -p
Use the following command to disable halt system on process death:
gabconfig -P
Halt on process
death
