3. Global options enLegacyId / li = NO enTimeZone / tz = YES
YES was useful only for network with 8.2 FTAs
enTimeZone / tz = YES
Even with a single TZ, YES should be the preferred option
enLegacyStartOfDayEvaluation / le = NO
Easier to understand but it changes the schedulation

6. Scheduling FINAL
Every working day at 7AM we extend the plan until 12PM of the next working day
07:00
12:00
12:00 of next working day

7. Scheduling FINAL Required settings Optional settings
enCarryForward / cf = ALL
extension to next work day w/ buffer
FINAL to run on every workday (at 7:00)
HOLIDAYS calendar defined
ignoreCals / ic = NO
Makeplan to be changed to extend until next work day
MakePlan –to `datecalc today + 1 workday pic mm/dd/yyyy` 1200 TZ America/NewYork
Set Until Time on JS to remove from plan uncompleted JS
with cf=ALL JS are not removed when a new plan is created
Optional settings
startOfDay / sd = 0000
enPreventStart = ???

8. Monitoring FINAL STARTAPPSERVER MAKEPLAN  Can be scheduled in advance
SWITCHPLAN  Most critical
CREATEPOSTREPORTS  No production impact
UPDATESTATS  No production impact

9. Monitoring FINAL Monitor FINAL jobs status (EDWA or external product)
SwitchPlan abend may not be reported since TWS is down
Monitor SwitchPlan long duration (EDWA or external product)
E.g.: alerting if SwitchPlan does not complete within the double of its normal duration
Periodically check FNCJSI
the size of Pre-Production plan is related to that
> planman showinfo
...
Start time of first not complete preproduction plan job stream instance: 03/25/ :00 TZ CET

10. Monitoring FINAL Job Status Changed FINAL.SWITCHPLAN to status EXEC
to status SUCC, ABEND, FAIL
Timeout = double of normal time
Timeout Action:
Send mail to administrator

11. EDWA/external monitoring/auto-ticketing
Use monitoring tools to be notified of failure in TWS
Job abends
Unlinked WS (outside FINAL timeframe)
TWS processes down on master
netman mailman batchman jobman WAS monman
TWS mailbox size
Forward the identified problem to ticketing application to automatically generate a ticket

12. EDWA/external monitoring/auto-ticketing
Can be used to monitor Jobs, unlinked WS, TWS processes, TWS mailbox size
Need to monitor EDWA itself
IBM Tivoli Monitoring
Integration provided with TWS can be used to monitor Jobs, TWS processes, TWS mailbox size
Monitor unlinked WS currently not provided in the integration
Can be implemented using BMEvents.conf events
Other monitoring tool
Jobs, unlinked WS can be implemented using BMEvents.conf events
Evtsize can be called to determine mailbox usage
TWS processes should be monitored through OS (pids directory contains TWS processes pids)

13. Monitoring EDWA Monitor WAS is running
This can be done monitoring the java process
Monitor that agents are monitoring (coming soon)
Agent monitoring status is turned off if the monitoring process are down or agent is not able to send events.
BMEvents.conf can be used to generate events on the master when an agent monitoring status goes down (261,262).
Monitor for failed Rule Actions
Message AWSAHL007E is written in SystemOut.log when the action fails

14. Other integrations Self service (via conman/Java APIs)
Allow your end-users to operate directly on their scheduling activities
Product like IBM Tivoli Service Request Manager can be used to implement an approval process before the action is performed
Custom GUIs can provide a simplified and limited interface design on the enduser need
Change management (via composer/Java APIs)
Promote your scheduling defintion from Dev to Q&A and from Q&A to Prod

15. Other tips
“conman” always return rc 0, you can workaround this limitation with a wrapper script that intercept returned errors and exit with different rc accordingly
Unlink Tool (coming soon)
“Check Health Status” command fron conman and WebUI diagnose unlink problems, .msg and Symphony files
Prevent losing events with EDWA
Modify EIF/monmaneif.templ and ssm/eif/tecad_snmp_eeif.templ setting: ConnectionMode=connection_less

16. Other tips (TDWC) Windows Domain Users? Improve TDWC scalability
Consider accessing it as LDAP user registry instead as LocalOS
Improve TDWC scalability
Set maxOpenConnections=“20000” for WC_adminhost and WC_adminhost_secure in eWAS/profiles/twaprofile/config/cells/DefaultNode/nodes/De faultNode/servers/twaserver/server.xml
Improve Graphical View scalability
Set isGrowable=“true” for TWSWebUIWorkManager in eWAS/profiles/twaprofile/config/cells/DefaultNode/nodes/De faultNode/servers/twaserver/resources-pme.xml
