The huge size of the organisation can be guessed by its year 2007 volume of credit and debit card transactions which grossed to 4 billion.The organisation is looking for evaluation and strategies to improve grey in the fields of Fault management, Configuration Management, Network management, Security Management and Account Management. Finally, the organisation is interested in developing a network Management tool to automate & simplify the areas mentioned before. This paper attempts to provide a strategic solution in all the areas of Fault management, Configuration Management, Network management, Security Management and Account Management.Fault Management is defined as the process of monitoring, identifying, correcting the errors in any system. The Fault management is of two types - Passive and Active. The Passive fault management is also knows the breakdown management as in this case the designated person or system does not work towards correcting the fault until the system has broken down.In case of the active fault management, the complete system is monitored by an automated system which keeps on checking all the network connections and keeps sending the report to an operator. The operator, through a set of parameter values, determines if the values are in "safe" range else the remedial action can be taken before the breakdown of the system happens.
The Fault Management systems are designed to operate in auto modes i.e. the system takes action on its own to correct the problem or else it sends an SMS, automated call to the escalation for any kind of human intervention to correct the problem. The following schematic diagram explains this system more clearly.
Diagram 1: Schematic of the Active Fault Management System
Following techniques are used to repair the faults identified in the network of the IT System -
Remove / neutralize fault, using redundancy
Retry without intervention (time redundancy)
Reconstruct data/state (data redundancy)
Work-around (configuration redundancy)
Substitution (code redundancy)
Tolerate fault: reduce service quality
Reduce speed, reduce precision
Use default, omit faulty parts
- Dynamic Reconfiguration
Organization of Fault Management at XYZ enterprise
XYZ enterprise would be using all the techniques mentioned in the previous section to efficiently handle the Faults at the enterprise's complex system. The management would be pro-active with the agreed safe parameters along with formal documentation on the escalation procedure.
Configuration Management is defined as the process of managing the software source code or any "configuration" items in its integrated format. All the changes to the configurable items are version controlled and are stored in software which allows the configurable items to be updated only after a set of processes are followed. Configuration Management helps to identify at any point of time, the current software code version, essential characteristics of the codes and any dependencies amongst the codes, if any. Unless, there is a methodology to manage the software codes, the changes to software can be a minor discomfort to a major issue with a potential to bring down the mission critical business applications.
Another important use of the Configuration Management process is the reduction of development effort in applications by re-using the existing software available in the organisation. The identification of the characteristics of the existing source in the organisat
