Azure AKS HCL HWA 10.2 HA certificate rotation across 4 MDMs fails zero-downtime; kubectl rollout restart triggers all StatefulSets simultaneously causing workstation "SSL unavailable".
What rolling strategy ensures HA certificate continuity?

A.Helm upgrade --atomic --wait --timeout=20m all charts
B.kubectl rollout restart statefulset wa-waserver-mdm1; sleep 120; repeat mdm2-4
C.Blue-green deployment new namespace; cutover DNS
D.RollingUpdate maxSurge=0 maxUnavailable=1 per namespace

정답:
Explanation:
AKS HA certificate rotation requires sequential kubectl rollout restart wa-waserver-mdm[1-4] with 120s sleep ensuring one MDM remains available for workstation SSL during rolling update; prevents total outage versus parallel restarts. Manual sequencing maintains active-active architecture continuity during certificate propagation.

HCL HWA 10.2 batchman PlanBox.msg/Server.msg desync during 2500-job symreq with T (bm check file) =150 and 800 file dependencies. Courier.msg jobman 92% capacity.
What dual optimization cascade resolves?

A.enLimitedJobManSemaphores=NO
B.T (bmNetmanPoll) =120; netman sync
C.evtsize PlanBox.msg, Courier.msg 28M
D.T (bm check file) =50; conman "limitdep 300"

정답:
Explanation:
T (bm check file) =50 with conman "limitdep 300" resolves 800-file dependency calculation delays causing PlanBox.msg/Server.msg desync and Courier.msg pressure; targeted batchman workstation processes optimization versus broad resizing or unrelated netman tuning.

HCL Workload Automation 10.2 server installation on IBM Power10 EC45 enterprise server (256 cores/4TB RAM) for mainframe hybrid scheduling encounters J9JIT24 fatal error during makprod of z/OS job streams. Java 11.0.19 installed. AIX 7.3 TL2.
Which server installation JVM sizing using precise -X options prevents JIT compilation OOM?

A.TWS_JAVA_OPTS="-Xms16g -Xmx96g -XX:+UseContainerSupport -XX:MaxRAMPercentage=75 -Xjit:count=50000"
B.JAVA_OPTS="-Xaggressive -Xcomp:multi 4 -Xtune:virtualized -Xjit:disableAsyncCompilation"
C.tws_env JAVA_MAX_RAM=75%; export IBM_JAVACOREDIR=/TWS/java_cores; ulimit -c unlimited
D.JobManager.ini [JVM] heapSize=96G newSize=16G survivorSize=2G

정답:
Explanation:
Power10 JIT requires -Xms16g -Xmx96g -XX:+UseContainerSupport -XX:MaxRAMPercentage=75 -Xjit:count=50000 allocating 96GB heap within 75% 4TB RAM constraint, enabling container cgroup awareness despite bare metal while limiting JIT compilations preventing code cache exhaustion during z/OS hybrid makprod. aggressive tuning risks latency, JAVACOREDIR diagnostic only, JobManager.ini heap scoped to engine excluding conman.

Question No : 7

Scenario: You need to uninstall a backup master domain manager in a high-availability setup for HCL Workload Automation 10.2 after promoting it temporarily.
What prerequisites must be met before uninstallation? (Select All that Apply)

A.Drop the shared database
B.Ensure no active plan references the backup
C.Remove workstation definition from database
D.Stop all processes on the backup using shutdown commands
E.Switch back to the primary master using switchmgr

정답:
Explanation:
Before uninstalling a backup MDM, promote the primary back to master role via switchmgr to avoid conflicts. Then gracefully stop all processes (app server, agents, netman) on the backup workstation. The workstation definition remains in the database for potential reuse, and the shared database is not dropped as it is still needed by the primary.

Question No : 8

Which parameter in the server installation of HCL Workload Automation 10.2 allows generation of default SSL certificates?

A.keystorePassword only
B.Provide password for default certificates
C.certman generate
D.sslkeysfolder path
E.enableCustomCert=true

정답:
Explanation:
In the server installation process, if default certificates are chosen, a password is provided which is used to generate and store default SSL certificates in designated directories for secure communication setup.

Question No : 9

Scenario: An administrator observes intermittent SSL handshake failures between fault-tolerant agents upgraded to 10.2 and an MDM using custom certificates post-10.2.1.
What specific considerations apply to FTA certificate propagation? (Select two)

A.Use twsinst with sslkeysfolder and sslpassword during upgrade
B.Automatic propagation via linkage only for dynamic agents
C.Run make secure after linkage for FTAs
D.Manual certificate installation required on FTAs below 10.2 linked to newer MDM
E.Update localopts SSL CA certificate path to custom trust file

정답:
Explanation:
Manual certificate installation required on FTAs below 10.2 linked to newer MDM using custom certificates, as automatic features are version-specific. Automatic propagation via linkage only for dynamic agents handles trust updates seamlessly, unlike FTAs which need manual steps.

Question No : 10

Planman UPGRDJSTREAM processing 3200 final streams during HCL HWA 10.2 production cycle shows 29% "Symphony locked" failures across mixed FTA/dynamic pool.
What sequence guarantees upgrade completion?

A.conman "flushq all"; planman create
B.conman "stopmonitor"; planman symreq all; planman UPGRDJSTREAM /FORCE
C.planman resyncplan all /FORCE; upgrade
D.planman extend 24h; retry upgrade

정답:
Explanation:
conman "stopmonitor" prevents event-driven locks; planman symreq all ensures Symphony consistency; UPGRDJSTREAM /FORCE completes 3200 streams eliminating 29% failures. Sequential isolation maintains production cycle upgrade integrity versus retries risking inconsistency.

Question No : 11

HCL HWA 10.2 monman trace TWS_home/trace/monman.20260107.trc shows "edwa connection timeout=180s" blocking event processor during Dynamic Workload Broker resource events. Audit trails show 18000 events/hour.
What trace+audit correlation diagnoses broker event storm?

A.grep "edwa|timeout|broker|resource" monman.*.trc; tail -f auditbox.msg | grep "resource|allocate"
B.conman "showmonitor"; netstat -an | grep event
C.localopts T(monmanPoll)=5; trace jobman
D.planman resyncplan /EVENTS

정답:
Explanation:
grep "edwa|timeout|broker|resource" monman.*.trc with tail auditbox.msg | grep "resource|allocate" correlates 18000 broker resource events/hour to edwa timeout=180s blocking event processor; trace+audit reveals Dynamic Workload Broker event storm vs monitor show missing timing or poll tuning masking throughput limits maintaining comprehensive event troubleshooting.

Question No : 12

In a high-availability HWA 10.2 setup, primary MDM at TWA_HOME=/opt/hwa/mdm1 fails over to backup MDM. Upon startup, backup reports "Installation paths mismatch: TWS_Eclipse_Install=/opt/hwa/mdm1_eclipse".
What installation path property was incorrectly configured during backup MDM install?

A.backup.eclipse.path=/opt/hwa/mdm2_eclipse
B.Use shared filesystem for Eclipse workspace
C.tws.eclipse.local=true on backup only
D.TWS_Eclipse_Install must match primary exactly

정답:
Explanation:
Backup MDM requires identical TWS_Eclipse_Install path to primary for plan synchronization and GUI compatibility. During twsinst -backup -from_mdm/opt/hwa/mdm1, the -eclipse_dir parameter must match primary's exactly. Mismatched paths cause Symphony file corruption during failover; correct by reinstalling backup with same Eclipse path.

Question No : 13

Which twsinst parameters are used to authenticate to the master domain manager during dynamic agent installation in HCL Workload Automation 10.2 when not using JWT?

A.-master <mdm_name>
B.-wapassword <password>
C.-tdwbport <port>
D.-wauser <user>
E.-tdwbhostname <host>

정답:
Explanation:
For standard authentication during dynamic or fault-tolerant agent installation, -master specifies the master domain manager workstation name, -wauser provides the HCL Workload Automation administrative user for login, and -wapassword supplies the corresponding password. These enable the agent to register securely with the master. -tdwbhostname and -tdwbport are for direct broker connection in some scenarios, but master-based authentication uses the wauser/wapassword combination.
