Web Layer

� Web Server provides the web container in which T24 Browser servlet is managed and run.

� Web Servers hosts Web Application Servers� jBOSS� IBM WebSphere Application Server� Oracle WebLogic�

� Any J2EE complaint Web Servers.

T24 Application Layer

� T24 Application Server hold the actual T24 software.� Holds Database as well in case the database is TAFC.� Software is in the form of Binary file and Libraries files, which are

compiled for native OS.� T24 Components

� Database Drivers in case Database other than jBASE.

� TAFC Dataguard.

� Transaction Journaling.

� Log Replication on Hot Standby� Log Replication on Hot Standby

� Online Backup

Database Layer

� Database Layer is to define different types of DB that can be used with T24.

� Stores the actual T24 data in form of tables.

� Database layer is part of T24 Application Server in case the DB is TAFC.TAFC.

� TAFC uses drivers to communicate with Database (Oracle, DB2, SQL).

� Clustering can be used, if DB allows in case of Multi-Server architecture.

T24 Browser

T24 Browser

� T24 Browser is a thin client browser based interface into the T24 application.

� No business logic or data is held locally on the client computer.

� All requests from the T24 Browser to T24 are message based.

� Between the browser and the Web Server, these messages are in � Between the browser and the Web Server, these messages are in HTML format, but are translated into XML at the Web Server by the T24 Browser Servlet for the rest of their journey into T24.

� Communication between the Browser and T24 is stateless in that any request or transaction from the T24 Browser is completely independent of the last or subsequent requests or transactions.

� Works with Microsoft Internet Explorer 6 and Firefox Mozilla.

TAFC

TAFC

TAFC

� TAFC is an application development and database management system.

� TAFC uses the ‘C’ compiler to compile programs.

� TAFC is an open database and can communicate with external database like Oracle, DB2 etc with help of drivers.

� TAFC uses jEDI (jBASE External Database Interface) to communicate with other Databases.

� T24 Application uses TAFC runtime to execute the package.

TAFC Overview

� Can be viewed as tool set

� Used to construct T24 into standard ‘C’ code

� C code compiled using standard compilers into

Native System Executables

Native System DLLs

� Execution handled as any other standard Windows/Unix executable and

set of dynamic linked or shared libraries

� Can be viewed as a Database

� jBASE Hash Files and tools

TAFC Hash Files

� Provide very fast data access using hashing algorithms to balance and

locate data

� Hash files are implemented on top of the native file system.

� jBASE Hash files consist of a structure of primary groups/buckets

located at specific offsets in the file dependent upon the frame/bucket located at specific offsets in the file dependent upon the frame/bucket

size for the file type. J4 use 4096 bytes frame size.

� jBASE Hash J4 files on some platforms can utilize OS memory

mapping functionality or alternatively can also be configured for use

over networked file systems using the standard OS read and write API

Hash File Maintenance

� Tools for Hash file maintenance and modification

� jstat Provides statistical information about file� Jrf Tool to resize file� jcheck Tool to verify structure of file� jbackup Database file backup� jrestore Database file restore� jchmod Tool to modify file properties� jchmod Tool to modify file properties

LOG - Log updates to transaction journalTRANS - Include updates as part of transactionBACKUP - Include as part of jbackup processNETWORK - Network file use read/write API

All above tools have a help option (-h) to display available options

TAFC Locks

� TAFC provides advisory locking capabilities for records independent of the underlying database

� Record locks� Locks taken on physical records in a hash file� Usually as a result of an advisory lock statement (READU)

�� Binary locks� Internal to jBASE� Taken when the system needs to lock a resource� For example when updating a file group (Hash files only)� Or updating journaling logs

TAFC Profile Tools

� jdiag -dvL� Provides snapshot of current environment/configuration

� WHERE (V� Provides verbose output about executing processes

� jprof� Online profiling tool to determine process profile

� JDIAG� Environment variable to provide low level information

Branch Resilience

Branch Resilience (BR)

Branch Resilience

� Why Branch Resilience??

� To provide a minimum service to the customers, inca se

communication between Data Center and the Branch is interrupted

Branch Resilience

� T24 BR Module

� Concept of storing a copy of some amount of data at the branch level

as well as Central Server.

� BR module allows maintenance of a backup system at branch level.

� Not possible to run full branch service.� Not possible to run full branch service.

� Used to give basic but important service to custome rs.

� Used to re-establish data when the connection to th e main server is

back-up.

� Currently only TELLER, TELLER.ID & PASSWORD.RESET i s

supported.

� System is said to be “OFFLINE” if not connected to central server.

Branch Server

� Branch Server Contains

� A Web Server (eg : jBOSS)

� TAFC – jBASE Agents

� T24 Libraries

� TAFC Database

T24 Interfaces solution

There are 3 groups of interfaces protocol� Batch (Inbound/Outbound)

• Daily extraction• Pseudo real-time extraction (every x minutes)• MetaData extraction…
