You can set system properties that various components use
to control how applications and other aspects of the product work.
A system property is a key-value pair that is used at the system
level.
Global properties
A global property applies to the entire system. The property
applies to all the server instances that use a common database, including
a clustered environment.
Instance properties
An instance property applies to a specific system server.
When you create both a global value and an instance value for the
same property, the instance value takes precedence.
Options for system properties
Every property defined in the System Properties application
has options that you can manage.
System properties and encryption algorithms
The default encryption algorithm for system properties
is DESede. You can configure different properties for the CRYPTO and
CRYPTOX data types.
Values of system properties in files and applications
To simplify working in a development environment, you can
assign a value to a system property in both a file and in the System
Properties application. The value in the file takes precedence.
Fetch stop limit memory errors
A Java™ virtual memory
heap out-of-memory error is caused by an operation that fetches and
constructs too many objects into one Maximo® business object (MBO)
set. This type of error can disconnect all users from the server.
You can use the mxe.db.fetch system properties
to configure the fetch limit, which can help prevent out-of-memory
errors.
