Consider the following excerpt generated by the cmclquery command: NODE_NAME zappa NETWORK_INTERFACE lan0 HEARTBEAT_IP 192.168.0.20 NETWORK_INTERFACE lan2 STATIONARY_IP 22.214.171.124 NETWORK_INTERFACE lan6 HEARTBEAT_IP 126.96.36.199 NETWORK_INTERFACE lan4 # Possible standby Network Interfaces for lan2: lan4 What can you determine given only the information above?
lan4 is a standby interface; lan2 does not carry heartbeat packets
Consider the following entry from a package control file: SERVICE_RESTART="-r 2" Which statement is true?
The service will fail if the process dies 3 times.
Based on the cmviewcl output, which statement is correct?
A failure of oracle9i will causealien_pkg to halt.
Which statement describes the parameter NETWORK_POLLING_INTERVAL in the cluster ASCII configuration file?
It defines the frequency at which the node will check for network connectivity.
A package along with its associated volume groups and data are being migrated from one Serviceguard cluster to another. The volume groups were exported from the old cluster and imported into the new one. The following error is produced by cmcheckconf: Error: Volume group /dev/vg70 currently belongs to another cluster. It cannot be included in this one. Error: Volume group /dev/vg75 currently belongs to another cluster. It cannot be included in this one. Maximum configured packages parameter is 30. Configuring 7 package(s). 23 package(s) can be added to this cluster. cmcheckconf : Unable to verify cluster file: /etc/cmcluster/cmclconf.ascii. Which change will resolve this error?
The disks must first be marked as non-cluster hardware.
Following is an excerpt from a legacy package control script: SERVICE_NAME="MON_MON" SERVICE_CMD="/etc/cmcluster/MON/MON_MON.sh monitor" SERVICE_RESTART="-r 2" What does the "-r 2" mean? (Select two.)
The service MON_MON is restarted 2 times before the package fails over.
The package will fail over to the adoptive node if the monitoring script MON_MON.sh gets restarted more than 2 times.
Your customer wants you to design an HA solution with HP-UX and Serviceguard that runs the customer's Business Critical SAP production system as Serviceguard package,pkgA, and the customer's Development SAP system as Serviceguard package, pkgB. You design two vPars (vpar1 and vpar2) on serverA and two vPars (vpar3 and vpar4) on serverB. What is a good design for this cluster to provide the maximum high availability? (Select two.)
Cluster vpar1 and vpar3 and runpkgA on these clustered vPars.
Cluster vpar2 and vpar4 and runpkgB on these clustered vPars.
The final step to create a 2-node cluster is to issue the command cmapplyconf. In which state should the cluster lock volume group be in before issuing the cmapplyconf command?
activated in standard mode on the node where the command is issued
Which statements are correct regarding a Serviceguard cluster with SGeRAC and Oracle RAC? (Select two.)
The shared disk devices can be a SLVM raw device, CFS, or Oracle ASM raw device.
You can have more than one Oracle instance accessing the same database at the same time.
In a Serviceguard environment, which feature provides the opportunity to perform rolling upgrades on the application software by temporarily moving a package to another system?
local application binaries
In a two node cluster, two identical servers (same CPU, memory, and I/O card configurations) are designed to host the application and database servers of a 3-tier application. Under normal operations the database is hosted on server A and the application server is hosted on server B. Which system middleware tool is helpful for rebalancing loads in the event of a single server failure, after both applications have migrated to the surviving node?
Workload Manager (WLM) can reassign system goals and resources (vPar CPUs) to the database and application to help rebalance the loads.
Which situations does Serviceguard provide high availability solutions for? (Select two.)
LAN card failure
Which statements are true about the Continentalclusters product? (Select two.)
Continentalclusters utilize a package to monitor the health of the second geographic location.
Continentalclusters are actually two clusters with manual failover from one cluster to another.
Cluster re-formations can occur from time to time due to current cluster conditions. Which conditions can initiate a cluster re-formation? (Select two.)
loss of power to a node SPU
excessive network traffic on heartbeat LANs
What is the function of the lock disk or Quorum server in a Serviceguard cluster?
prevents split brain syndrome
An application that is configured as a Serviceguard package in a 2-node cluster is performing badly. A consultant inspects the application and recommends changing an application parameter. This application parameter can effect a static kernel parameter under certain conditions. The customer has a standalone test system running the same application. Given this situation, how should application changes be handled in regards to Serviceguard?
Any application change should be tested outside the cluster to see if it mighteffect the OS and in further consequence all nodes that are running this package.
In the context of high availability, which phrase describes Mean Time To Repair (MTTR)?
mean interval of time to resume a service after a failure
A customer has a 2-node HP Serviceguard cluster running a mission critical Oracle database and a financial application. At the end of each month the server utilization spikes with no idle CPU resources and there is a need for additional capacity. Which HP Virtual Server Environment offering provides additional capacity and is best in this situation?
Temporary Instant Capacity (TiCAP)
If a Quorum service fails so that it is no longer available, which statement is true regarding the action that should or will take place?
Repair or restore the Quorum service.
Which command includes the CVM disk group cfsdg01 in a Serviceguard CFS cluster configuration?
cfsdgadm add cfsdg01 all=sw
After implementing a highly available Oracle database instance utilizing a template from the Enterprise Cluster Master Toolkit, a DBA wants to perform offline maintenance while keeping all filesystems mounted and the relocatable IP address available. What is the best method to accomplish this?
Enable the maintenance flag and perform database maintenance.
For Serviceguard troubleshooting, which log files should be configured across cluster nodes to utilize the Distributed Systems Administration Utilities (DSAU) log consolidation feature? (Select two.)
package log files
You are upgrading a system to HP-UX 11i v3 and want to use the new I/O subsystem features, load balancing and multipathing, for all multipath devices. Your customer also wants you to implement VxVM Veritas Volume Manager (VxVM) and Veritas Dynamic MulitPathing (DMP). Which statements are true in this situation? (Select two.)
You mustmigrate existing legacy LUNs to agile addressing.
The HP-UX 11i v3 I/O subsystem provides multipathing and load balancing by default. This is often referred to as native multipathing.
Which Serviceguard add-on product decreases the failover time in a 2-node cluster?
