Store Messages in Multiple Stores
The EMS server writes PERSISTENT messages to disk while waiting for confirmation of receipt from the subscriber. Messages are persisted to a store. The EMS server can write messages to different types of stores: file-based stores, grid stores, and FTL stores.
By default, the EMS server writes persistent messages to file-based stores. There are three default store files, as described in Default Store Files. You can configure the system to change the default store files and locations, and also to store persistent messages to one or more store files, filtering them by destination. Stores are defined in the stores.conf configuration file, and associated with a destination using the store destination property.
Stores have properties that allow you to control how the server manages the store files. For example:
With the multiple stores feature, you can configure your messaging application to store messages in different locations for each application, or to create separate files for related destinations. For example, you can create one store for messages supporting Marketing, and one for messages supporting Sales. Because stores are configured in the server, they are transparent to clients.
When using the multiple stores feature, all stores must be of the same type. Configuring multiple store types in the same server is not supported.
The EMS Administration Tool allows administrators to review the system’s configured stores and their settings by using the show stores and show store commands.
