Class NodeStringLengthWorker

java.lang.Object

org.alfresco.repo.node.db.NodeStringLengthWorker

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class NodeStringLengthWorker
extends Object
implements org.springframework.context.ApplicationContextAware

Max String Length Worker

What it is

A worker for a scheduled job that checks and adjusts string storage for persisted strings in the system.

Settings that control the behaviour

• ${system.maximumStringLength} - the maximum length of a string that can be persisted in the *alf_node_properties.string_value* column.
• ${system.maximumStringLength.jobQueryRange} - the node ID range to query for. The process will repeat from the first to the last node, querying for up to this many nodes. Only reduce the value if the NodeDAO query takes a long time.
• ${system.maximumStringLength.jobThreadCount} - the number of threads that will handle persistence checks and changes. Increase or decrease this to allow for free CPU capacity on the machine executing the job.
