Embedding HCL OneDB™The HCL OneDB™ Embeddability Guide describes how to embed HCL OneDB™ in your applications.
Manage memory in embedded environmentsYou can manage memory in embedded environments by enabling the database server to automatically rotate and delete online message log files, configuring the actions that the server takes to continue processing when memory is critically low, and enabling the server to reserve a specific amount of memory for use when critical rollback activities are needed and the server has limited free memory.
Maintain a targeted amount of memory in embedded applicationsYou can configure the database server to continue processing when memory is critically low, instead of returning an out of memory error.

Maintain a targeted amount of memory in embedded applications

You can configure the database server to continue processing when memory is critically low, instead of returning an out of memory error.

You specify the criteria for terminating sessions based on idle time, memory usage, and other factors so that the targeted application can continue to process. Configuring the low memory response is useful for embedded applications that have memory limitations.

To configure a targeted amount of memory in embedded applications:

Set the LOW_MEMORY_MGR configuration parameter to 1, which enables the automatic low memory management when the server starts.
Set the threshold parameters for the amount of memory to maintain by using an SQL administration API command with the scheduler lmm enable argument.

To disable automatic low memory management, run an SQL administration API command with the scheduler lmm disable argument.
