1.4 JP1/AJS3 database configurations
JP1/AJS3 - Manager uses an embedded database as standard for managing information about jobs and jobnets. However, an ISAM database can be used for reasons of compatibility with a previous version or if required by the operating environment.
JP1/AJS3 - Manager supports two types of database configurations:
-
Standard configuration
-
Standard configuration without ISAM
The following figure shows the database configurations supported by JP1/AJS3 - Manager.

In cases where JP1/AJS3 - Manager operates in a cloud environment, you can use an external database provided by the cloud service, instead of the embedded database, in the standard configuration without ISAM.
For details about the external database, see 2.11 Considering use of an external database in a cloud environment in the JP1/Automatic Job Management System 3 System Design (Configuration) Guide.
- Supplementary note
-
In version 11-00 or earlier, a configuration that uses only an ISAM database (compatible ISAM configuration) can be used to maintain compatibility with JP1/AJS2 version 8 or earlier.
In version 11-10 or later, however, the compatible ISAM configuration is not supported.

If you want to update a database that is in the compatible ISAM configuration, you must change the configuration to the standard configuration.
For details about how to change the configuration of a database to the standard configuration, see 8.5 Upgrading JP1/AJS2 - Manager to JP1/AJS3 - Manager in the JP1/Automatic Job Management System 3 System Design (Configuration) Guide and 8.8 Upgrading JP1/AJS3 - Manager that uses the compatible ISAM configuration in the JP1/Automatic Job Management System 3 System Design (Configuration) Guide.
Note that, in cases where no database configuration type is specified in this manual, the standard configuration applies.
Each database configuration is described next.
