PowerHA is an RSCT aware client. RSCT is distributed with AIX. RSCT includes a daemon called group services that coordinates the response to events of interest to the cluster (for example, an interface or a node fails, or an administrator makes a change to the cluster configuration).Developer(s): IBM.

Explanation: The Resource Monitoring and Control daemon on the specified node has not answered a Group Services responsiveness request within seconds. User Response: The Resource Monitoring and Control daemon on the specified node should eventually terminate and then be it does not, the administrator must terminate the non-responsive daemon using the kill command.

Group Services is a distributed subsystem of the IBM Reliable Scalable Cluster Technology (RSCT) on the Rsct Group Services Programming Cluster Applications book system. If you are writing a new application or considering updating an existing application, Group Services may help your application improve its availability in a.
Group Services offer a simple programming model because it is based on a small number of core concepts: it is a cluster-wide group membership and synchronization service based on the publish/ subscribe model, which maintains an application-specific state for each group. Configuring Group Services A set of AIX® systems can be configured as an RSCT peer domain using the configuration resource manager.
All services provided by the Group Services subsystem are within a single domain only. Managing Group Services You can manage system resources, which may or may not be subsystems, that use Group Services to be highly available. This document is intended for programmers of system management applications who want to use group services to make their applications highly available.

Reliable Scalable Cluster Technology (RSCT) is a set of software components that together provide a comprehensive clustering environment for AIX, Linux, Solaris, and Windows operating systems.
RSCT is the infrastructure used by a variety of IBM products to provide clusters with improved system availability, scalability, and ease of use. This book describes how to use the monitoring function of the Reliable Scalable Cluster Technology (RSCT) Resource Monitoring and Control application for AIX®.
It also provides reference material about the RSCT application, including a summary of components, messages, and predefined monitoring functions. Who Should Use This Book.
RSCT is a proven cluster software that can enable high availability and distributed management applications, such as Tivoli Storage Manager, IBM DB2®, PowerHA and so on. RSCT is a set of software components that together provide a comprehensive clustering environment for IBM AIX®, Linux, Solaris, and Microsoft® Windows®.

RSCT is the infrastructure used by a variety of IBM® products to provide clusters with improved system availability, scalability, and ease of use.
RSCT uses CTHATS (Cluster Technology High Availability Topology Services) to monitor the status of the NIC(s). RSCT sends heartbeats across all available (default) network subnets to the peers in the cluster and is monitoring for heartbeats back from those peers as well.

Next page Group Services Application Program Interface (GSAPI) This is the application programming interface that GS clients use to obtain the services of the Group Services subsystem. These API calls are used by both the CSM and GPFS products.
Special procedure when RSCT is installed from a System Image or NIM Since RSCT stores node specific configuration information in the /etc and /var/ct/cfg directories, creating a system (mksysb) image from a node and restoring it to another node may cause unexpected behavior from the RMC subsystem.

RSCT is the infrastructure to provide clusters with improved system availability, scalability, and ease of use.
Two RSCT daemons are used by GPFS to provide topology and group services. They are the hagsd and hatsd daemons. The hagsd daemon relates to the Group Service subsystem. The function of the Group Services subsystem is to provide other subsystems with a distributed coordination, messaging, and synchronization.

When failure causes a cluster to be partitioned in two sets of VE nodes, the partition consisting of the larger number of VE nodes becomes the new cluster. When the two partitions have the same number of VE nodes, the partition containing the "quorum" VE node is selected--where the quorum VE node is a so-designated VE node in the original.
The importance of guaranteed end-to-end quality of service (QoS) increases as business-to-business (B2B) interactions become increasingly sophisticated, lengthy, and involve more sites. The collaboration between tiers to supply functionality can be extended to provide QoS.
In this paper, we focus on end-to-end availability. In multi-tier computation, support for transparent failovers is often Cited by:. TSAMP will not issue a start or stop order against a resource while TSAMP is in manual mode. However, RSCT will still invoke the CritRsrcProtMethod to protect resources if its conditions are met.
