1.1 Summary
1.1.1 Fault management principle
Principles of fault analysis, positioning and handling:
In order to resume business as soon as possible as the principle.
When locating the fault, the fault data information should be collected in time, and the
collected fault data information should be kept in the mobile storage medium or other
computers in the network.
When determining the troubleshooting scheme, the impact should be evaluated first and given
priority to ensure the normal delivery of services.
Third party hardware failure, you can view the relevant information of the third party or call
the service number of the third party company.
If the fault point cannot be located or the fault cannot be solved according to the manual,
contact technical support to minimize business interruption time.
Notes before positioning and processing:
Strictly abide by the operating procedures and industry safety rules to ensure personal safety
and equipment safety.
The fault phenomenon should be analyzed first, and the cause should be located before
processing. In the case of unknown reasons, blind operation should be avoided, leading to the
expansion of problems.
Before handling faults, any records of the fault site should be kept, and data or logs cannot be
deleted at will.
In dealing with faults, in order to ensure the security and privacy of the customer network, if
the relevant fault log is required, please get the consent and authorization of the customer in
advance.
Before making any modifications, first back up the data through script export, manual backup,
etc.
Any problems encountered during maintenance, various original information shall be recorded
in detail.

All major operations such as restart process shall be recorded and the feasibility before
operation shall be carefully confirmed with proper backup, emergency and safety measures.
After the system is restored, the operation situation must be observed to confirm that the fault
has been eliminated and the relevant treatment report should be filled in time.
Use high-risk operations and commands carefully.
Requirements for maintenance personnel:
Have the basic knowledge of network equipment, operating system and database, master their
common operation commands, and can skillfully use them for maintenance work.
Be familiar with the logical structure of the field HCS IOC Software Digital Twin
Visualization Platform service system, the correspondence between the components of the
HCS IOC Software Digital Twin Visualization Platform service system and the field
equipment, and the physical connection relationship between the field equipment.
Familiar with HCS IOC Software Digital Twin Visualization Platform business process and
system structure, and skilled in operating business related components.
Understand the basic fault-related positioning and handling methods.
1.1.2 Deal with ideas
When the current problem failure occurs, proceed according to the following process.

1.2 Information gathering
1.2.1 State
Strictly follow the following principles during the information collection operation:
Any maintenance operation must be authorized by the customer and prohibit any maintenance
operation beyond the customer approval scope.
Sending the problem location data out to the customer network must be authorized by the
customer.
1.2.2 Basic information collection
Collect bureau point information
After the failure occurs, as the first condition of the problem positioning, through the collection of local
information, let the technical support and research and development personnel.
Quickly understand the situation of the site, at the same time, feedback the contact number of the site
engineer, to ensure the smooth contact channel.need.

When the above failure occurs, it can first consider checking the corresponding log in the operation log
service of "Operation And Maintenance Control Center > Log Management > Operation Log", mainly
viewing the abnormal information in the "operation log"; or switch to the service status at the back end of
the server to view the service status and view the log of the service startup abnormal service; judge the
reason of the abnormal service startup by viewing the "/opt/sdc/me/webapps/server/me-project-biz/logs"
log.
