You must decide whether to use a file store or a data store
for your messaging engine, by considering the advantages of each type.
Using a file store rather than a data store for your messaging
engine can have several advantages:
- Better performance
- To achieve best performance using a data store, you often have
to use a separate remote database server. With file store you can
achieve even better performance without having to use a separate remote
database server.
- Low administration requirements
- The file store combines high throughput with little or no administration.
This makes it suitable for those who do not want to worry about where
the messaging engine is storing its recoverable data. File store improves
on the throughput, scalability, and resilience of Apache Derby.
- Lower deployment costs
- Use of data store might require database administration to configure
and manage your messaging engines. File store can be used in environments
without a database server.
Some organizations prefer to use data store because it uses their
existing resources more effectively. For example, this might be the
case for a company with a strong team of database specialists, or
a stable database infrastructure.
Data stored in both data store and file store benefit from security
features provided by
WebSphere® Application Server when
accessed using the
WebSphere Application Server APIs,
that is when using JMS messaging. Further security features are available
depending on the type of message store you use. For more details see
File stores and
Data stores.
- Data store: you access your chosen database by using a userid and
password that is administered using the supplied tools for your specified
DBMS. Logical and physical separation of your database server can
also be used to improve the overall security of your data.
- File store: additional security can be provided when using a file
store by careful consideration of your file store files. For example,
using a secure network-attached drive to store your file store files
improves the physical security of your data. Another example is storing
your files on an operating system encrypted file system.
Both file store
and data store offer high availability capabilities. For more details
