The PATCH request body is a JSON object formatted according to the System for Cross-domain Identity Management (SCIM) patch request. The Configuration API supports a subset of possible values for the path attribute that indicates the configuration attribute to modify.

Modify the configuration object's attributes according to the information in the following table, which details the comparable dsconfig modify-[object] options to each PATCH request.

Operations and PATCH requests to modify the configuration object's attributes
Operation PATCH request Comparable dsconfig modify-[object] options

Set the single-valued description attribute to a new value.

 
{  
  "op" : "replace",  
  "path" : "description",  
  "value" : "A new backend."
}
 
$ dsconfig set-backend-prop
  --backend-name userRoot \  
  --set "description:A new backend"

Add a new value to the multi-valued jeProperty attribute.

 
{
  "op" : "add",  
  "path" : "jeProperty",  
  "value" : "je.env.backgroundReadLimit=0"
}
 
$ dsconfig  set-backend-prop --backend-name userRoot \  
  --add je-property:je.env.backgroundReadLimit=0

Remove a value from a multi-valued property. In this case, path specifies a SCIM filter identifying the value to remove.

 
{
  "op" : "remove",  
  "path" : "[jeProperty eq \"je.cleaner.adjustUtilization=false\"]"
}
 
$ dsconfig set-backend-prop --backend-name userRoot \  
  --remove je-property:je.cleaner.adjustUtilization=false

Second operation to remove a value from a multi-valued property, where the path specifies both an attribute to modify and a SCIM filter whose attribute is the following value.

 
{
  "op" : "remove",  
  "path" : "jeProperty[value eq \"je.nodeMaxEntries=32\"]"
}
 
$ dsconfig set-backend-prop --backend-name userRoot \  
  --remove je-property:je.nodeMaxEntries=32

Option to remove one or more values of a multi-valued attribute. This has the effect of restoring the attribute's value to its default value.

 
{
  "op" : "remove",  
  "path" : "id2childrenIndexEntryLimit"
}
 
$ dsconfig set-backend-prop --backend-name userRoot \  
  --reset id2childrenIndexEntryLimit

The following is the full example request.
