4.10.5 Central Scope databases

The Central Scope has two databases: a monitoring objects database and a host information database.

• Managing the monitoring objects database
  The monitoring objects database is managed by JP1/IM - Manager and contains the object information displayed in JP1/IM - View.
  This database is updated on request from JP1/IM - View and on receipt of a JP1 event that changes the status of a monitoring object.
  Note that the following processing to update the monitoring objects database might take some time to complete:
  
  • Updating a server tree from the Monitoring Tree (Editing) window
  • Importing database information to the monitoring objects database by the jcsdbimport command
  If the OS shuts down, or if a failover occurs in a cluster system, while this update processing is in progress, the database could become corrupted.
  To prevent corruption of the database, JP1/IM provides an automatic backup and recovery function. When this function is enabled, the database is automatically backed up before either of the above types of update processing is performed, and is automatically restored to its former state if a problem occurs. If the update processing is successful, the backup data is automatically deleted.
  This function is enabled for a new installation of JP1/IM, but is disabled when an upgrade installation is performed. To enhance the system's fault tolerance, we recommend that you enable the function if upgrading JP1/IM.
  To enable the function, prepare an automatic backup and recovery settings file (auto_dbbackup_xxx.conf) for the monitoring objects database, and then apply the setting using the jbssetcnf command.
  
• Managing the host information database
  The host information database contains information specific to JP1/IM - Manager (JP1/IM - Central Scope) and is managed within JP1/IM - Manager (JP1/IM - Central Scope).
  

You can import and export information to the Central Scope databases using the commands shown in the table below.

Table 4-8 Commands for importing and exporting database information

Command name	Purpose
jcsdbexport command	Acquire information from the monitoring objects database.
jcsdbimport command	Save information to the monitoring objects database.
jcshostsexport command	Acquire information from the host information database.
jcshostsimport command	Save information to the host information database.

You can check database information using the jcsxxexport commands, and you can migrate the environment to another server using the jcsxxexport commands in conjunction with the jcsxximport commands.
