Features of CBS

• Centralized Banking Solution
• Data of all the customers are centralized

• Facilitates real time access of customer data
  from any of the connected branch or office.
• Role based access control
• Parameter setup is centralized
• Role out of products and schemes are uniform and
  achieved from central location

8
Features of CBS .contd.

• Standardized procedures across the bank

13
How does Surround Application Works?

• Surround applications like ATM , IBS are
  different systems and they can not communicate
  directly with CBS.
• An intermediate server known as Connect 24 (
  Bancsconnect) facilitates the communication.
• Communicate to CBS in ISO8583 standard format.
• ATM and IBS are required to be available to the
  customers on 24 X 7.
• But during the day end , day begin and other
  maintenance period, the CBS server may not be
  available for these ADC ( Alternate delivery
  channels)

14
How to provide the Services?

• Another server known as CSIS (Centralized Stand
  In Server) is introduced
• CSIS will be have the latest / current account
  details ( like balance, transactions etc,) as
  available in CBS DB server.
• It gets the continues updates from CBS DB server
• BC will take ADC transactions to CSIS during the
  outage of CBS DB server.
• Customer is serviced

15

• Precaution to be taken is
• When the CBS DB server is UP, the Transactions
  made in the CSIS server are to be updated first.
• System has been designed to handle so.
• In case it is not updated , the transactions of
  CSIS will not be reflected in CBS DB
• Similarly, in case the CSIS server is down when
  CBS DB is up and functioning, the transaction
  details of CBS DB will not be reflected in CSIS.
• Both are not desirable
• It is monitored and managed 24 x 7 by DC

• Redundancy and Fall back
• Disaster Setup

18

• Technology will face hiccups
• Adequate redundancy is to be build
• In every possible stage of the setup
• Data Centre (DC)
• DRS with 100 computing power
• Data is replicated to DRS continuously from DC,
  with a time gap of 30 mts.
• Storage based replication for cbs
• Oracle based ( data guard).
• DRS can be started within 2 hours of DC
  disruption.

19

• However DRS switch over is the last resort.
• Sufficient redundancy has been build in the DC
  setup
• The servers are in clusters
• DB server has a similar server of same capacity
  and power
• In case the main DB server fails the standby
  server will start functioning within a time lag
  of 10- 15mts.
• This time is required to start the services in
  the standby server
• Web servers are in clusters ( fail over) so as
  application servers.

20

• Storages are in RAID 10
• Every bit of data is written in 2 disks (
  Mirroring)
• Any one disk failure will enable us to retrieve
  the data from the mirrored disk
• System handles it automatically.
• NETWORK redundancy
• ZNCs are connected to DC and DRS through separate
  lease line
• DC and DRS are connected through link from BSNL
  and Reliance ( 2 separate links)
• Any link failure between ZNC and DC
• Connectivity can be established through ZNC
  -gtDRS-gtDC

21

• ZNCs and DC / DRS have ISDN connection , which
  shall be used for connectivity in case of lease
  line failure
• The connection between NC ZNC and BOs NC /
  ZNC
• Are established with LL and ISDN
• Now the second connection is established with
  VSAT or RF.
• But, still the connectivity is lost at branch
  level
• BCP is to be followed for uninterrupted customer
  service.

22

• CBS Flow of Transactions

23

• User access CBS either from PC or Thin client.
• It is a web browser based access ( I.E)
• Similar to Internet browsing
• URL is intranet address
• Access is granted after authentication of userid
  and password
• User command is transmitted from PC on commit
• F4 or F10

• USER GROUPS
• IN CBS

31

• All users logging into the application have a
  unique user ID and a password.
• Based on the kind of banking operations performed
  by these users they are grouped into different
  user Groups.

• CAPTIVE The CAPTIVE user with a captive status
  can access the data belonging to his service
  outlet alone but can inquire on the accounts
  belonging to other SOL.
• FREE FREE user can access the data belonging
  to all service outlets.

35

• CBS Case Setup at PNB

36

• It is one of the largest Single instance Oracle
  database
• Maximum number of concurrent users 17000
• The size of the database is around 4 TB
• Daily transactions of around 20 22 Lacs
• ADC transactions is around 2 Lacs (daily)
• Separate MIS server

37
Central data repository -improve quality -removes
in consistency -avoids duplicity.

• Proposed IT Infrastructure to meet the total
  business needs

The surround application will be managed by
focused teams
CBS Transaction Processing system
EDW MIS and Data Mining system
User will interact with CBS and EDW only
New Business requirements can be met with either
a new application or customisation of CBS
