Job Management Partner 1/Base User's Guide
The following describes the required environment settings for using JP1/Base in a cluster system. For the setting procedure, see 3.4.3 Setup.
- Organization of this subsection
- (1) Specifying a shared folder
- (2) Communication protocol
- (3) Common definition information
- (4) Registering with clustering software
(1) Specifying a shared folder
When setting up a logical host, specify a shared folder for sharing information between the primary and secondary servers. In the shared folder, the following files and folders are created.
Shared file type Folder for the shared files Definition files shared-folder\jp1base\conf\ Log file shared-folder\jp1base\log\ Event server settings file shared-folder\jp1base\event\ Assign a shared folder to each logical host. You must not assign the same folder to different logical hosts. The following shows an example of folder creation on a shared disk.
- Example: Specify \shdsk\node0 as a shared folder for logical host node0.
\shdsk\node0\jp1base\conf\ \shdsk\node0\jp1base\log\The event service can be set up to independently run in cluster mode. However, if you set up the environment according to 3.4.3 Setup, JP1/Base automatically specifies the logical host names in the event server index file (index) and creates the event server settings file (conf) in a shared folder.
(2) Communication protocol
When you set up the JP1/Base environment to support a cluster system, the socket binding method used in TCP/IP communication is automatically changed to IP addressing. This change affects settings for the logical hosts to be created and their constituent physical hosts. For details on the JP1/Base communication protocol, see 1.10 Communication protocols of JP1/Base.
To configure both physical and logical host environments on the same host, you need to set up the network control. For details, see 3.4.7 Settings to configure both physical and logical host environments on the same logical host.
(3) Common definition information
In JP1/Base and the programs that require JP1/Base (JP1/IM, JP1/AJS, or JP1/Power Monitor), information about the logical hosts is set as common definition information in the local disk. You must therefore set identical information about each logical host.
The common definition information is updated when you:
- Change the common definition information for JP1/Base and the programs that require JP1/Base (JP1/IM, JP1/AJS, or JP1/Power Monitor).
- Change the user mapping information.
- Change the authentication server.
- Delete the common definition information on the logical host.
- Change the password management information for an OS user.
- Change the jp1hosts information.
If you change the common definition information, match the information on each server, referring to 3.4.5 Modifying common definition information.
(4) Registering with clustering software
To enable the cluster software to control the JP1/Base on the logical host, you must register the JP1/Base service corresponding to the logical host to the cluster software. Logical host services are created when the logical host is set up.
