No Issue Resolution
1 Difficulty to identify meter status
calls
Develop tools to identify status of calls by
account and meter
2 Frequent planned downtime -
Oracle Database maintenance
• Monthly task on comm log purge
• Quarterly job on DB reorg
3 Longer backup time - no data
archiving function available in
IEE
• Monthly comm log purge
• Communicate/discuss with Itron on
workaround
4 To identify root cause of failure
meters whether due to IEE,
communication or meter
TNB uses tools (Failure analysis) based
on data from IEE comm log, diva log
(PRI card log) and xml file
5 Data mismatch between IEE and
billing system
Develop tools to identify data mismatch
as and when received configuration file
from billing system
OPERATIONAL CHALLENGES – DATA & IT RELATED
No Issue Resolution
1 Unavailability of person in charge
for site maintenance
Proper coordination with regional staff
2 Premise closed Proper coordination with regional staff
and end customer
3 Change of tenancy Relocate to new site and update list for
asset tracking on modem installation
OPERATIONAL CHALLENGES – SITE
No Issue Resolution
1 Low signal - outskirts, basement Forward the list to service provider and
they will do upgrade work to burst the
signal
2 Limitation of number of channel
(old equipment)
Replacement of old equipments have
been carried out during the project
implementation
OPERATIONAL CHALLENGES - COMMUNICATION
No Issue Description
1 Configuration/
Functionality
a. Pervasive DB not updated (MM,CM,RM) or takes time to
update.
b. Complexity on meter swap function – many meter brand
and number of channel not unique
c. Replication on SM/dialers not available (TNB policy is to
have duplicate setting for DR)
d. Data archiving is not available and TNB policy is to kept
data up to 7 years
e. Load unbalance at Service Mode (manual)
f. Stability of Itron’s services – frequent restart Itron’s
services
2 Reporting a. Extended event code is not in the event report.
b. Sometime communication log delayed. Impact is on
activation takes more than 30 minutes
c. Missing Interval Report – no option to select by group
and cannot run if more than 1000 SP
3 Monitoring a. Task monitor statistic cannot be used to identify status
on meters
b. Validation queue – not user friendly where can’t export to
excel or copy/paste function
OPERATIONAL CHALLENGES – MDM SYSTEM ON IEE ver 5.3
No Project Description
1 DR for Service
Mode and
Dialers
Objective is for full redundancy for all RMR
infrastructure
Project mode only one set of SMs and dialers
RMR categorized as critical 4
Challenge to synchronize data between production and
DR
2 Technical
Refresh
To replace existing hardware with new hardware
IEE version upgrade
Data archiving
3 RMR tester RMR technicians developed gadget to detect status of meter
comm. port for site maintenance
IN HOUSE PROJECT
No Issue Considerations and challenges
1 IEE version
upgrade
Auto replication between production and disaster
recovery for SMs/Dialers
Simplify on adding account/service point in IEE
Complexity of meter swap
Data migration from ver 5.3 to ver 7
2 New hardware Real Application Cluster (RAC) technology or non-RAC
technology
Hardware design for PR, DR and staging environment
3 Data archiving ICT policy :
1 year data within 0.5 sec
Data within 7 years data in 3 min
Data older than 7 years period (best efford)
