Question
Which facilities are used to monitor all the LPARs in sysplex ?
A. PPRC
B. XRC
C. GDPS
D. None of the above
Answer
C. GDPS (Geographically Dispersed Parallel Sysplex).
Explanation
GDPS is a family of IBM solutions designed to provide high availability, disaster recovery, and automated operations for mainframe systems in a sysplex. It leverages automation and remote copy technologies to monitor and manage multiple LPARs across the sysplex.
GDPS monitors various aspects of the sysplex, including the status of LPARs, coupling facilities, network connections, and storage subsystems. It can automatically detect and respond to failures, initiating failover procedures to maintain system availability.
The other options are not directly related to monitoring LPARs in a sysplex:
- PPRC (Peer-to-Peer Remote Copy) and XRC (Extended Remote Copy) are remote copy technologies used for data replication and disaster recovery, but they do not specifically monitor LPARs.
- “None of the above” is incorrect because GDPS is the facility used for this purpose.
In summary, GDPS is the comprehensive solution used to monitor and manage LPARs across a mainframe sysplex environment, ensuring high availability and automated disaster recovery capabilities.
