CDM system properties.

Important: Starting with the Washington D.C. release, DevOps Config is being prepared for future deprecation. It will be hidden and no longer activated on new instances but will continue to be supported.

CDM system properties

PropertyDescription
sn\_cdm.variable\_regexThe regex used to capture variables referenced in a CDI value. With this value, the syntax to use a variable is: 
@@name@@
Default: @@\(\[^@\].\*?\)@@
sn\_cdm.cdm\_queue\_request\_expiry\_time\_msThe maximum time for a process to be available for processing before it is marked as expired. Default: 900000 ms \(15 min\)
sn\_cdm.cdm\_validation\_timeout\_msThe maximum time limit for a validation of a snapshot. Default: 900000 ms \(15 min\)
sn\_cdm.default\_node\_identifier\_keysThe keys used to identify node objects within an array node. Default: \(none\)
sn\_cdm.execute\_exporter\_async\_for\_standard\_requestIf set to `false`, exporter requests skip the request queue and their output is returned immediately. Changing this setting may decrease system performance if there are many export requests. Default: true
sn\_cdm.exception\_enabledIf set to false, the control exception functionality is disabled regardless of other policy settings. Default: true
sn\_cdm.node\_name\_allowed\_character\_regexThe regex used to validate the name of a node. Default allowed characters are: 
0-9, A-Z, a-z, _, -, ., %, $, whitespace, :, #
Default: `[\\w-.% :$#]`
sn\_cdm.app\_name\_allowed\_character\_regexThe regex used to validate the name of an application. Default allowed characters are: 
0-9, A-Z, a-z, _,-, ., whitespace, |, :, [], (), %, $, #
Default: `[\\w-.%$#() :|[\\]]`
sn\_cdm.snapshot\_name\_allowed\_character\_regexThe regex used to validate the name of a snapshot. Default allowed characters are: 
0-9, A-Z, a-z, _,-, ., %
Default: `[\\w-.%]`
sn\_cdm.exporter\_name\_allowed\_character\_regexThe regex used to validate the name of an exporter. Default allowed characters are: 
0-9, A-Z, a-z, _,-, .,%
Default: `[\\w-.%]`
sn\_cdm.exporter\_argument\_name\_allowed\_character\_regexThe regex used to validate the name of an exporter argument. Default allowed characters are: 
0-9, A-Z, a-z, _
Default: `[\\w]`
sn\_cdm.cdm\_max\_allowed\_open\_changesetsThe maximum allowed number of open changesets. Default: 10
sn\_cdm.preventative\_duplicate\_node\_name\_checkIf set to true, validating for node name duplication will check name usage across all other open changesets as well \(as opposed to limiting the check within the changeset\). Default: false
sn\_cdm.max\_allowed\_upload\_file\_sizeThe maximum payload size for upload of config data via the REST API. Default: 5 MB
sn\_cdm.max\_allowed\_cdi\_per\_applicationThe maximum number of CDIs allowed per application. If the number is exceeded, further upload of config data via the REST APIs is blocked. Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command: ``` new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications(); 
 Default: 100000

</td></tr><tr><td>

sn\_cdm.max\_allowed\_cdi\_per\_deployable

</td><td>

The maximum number of CDIs allowed per deployable. If the number is exceeded, further upload of config data via the REST APIs is blocked.

 Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command:

 ```
new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications();
Default: 10000
sn\_cdm.max\_nodes\_in\_memoryThe maximum number of nodes that can be supported when using the `queryTree` method of `CdmQuery`. Default: 10000
sn\_cdm.reserved\_node\_namesNames that cannot be used for nodes. Default: vars, collections, deployables, components
sn\_cdm.max\_allowed\_cdi\_per\_shared\_componentThe maximum number of CDIs allowed per shared component. If the number is exceeded, further upload of config data via the REST APIs is blocked. Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command: ``` new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications(); 
 Default: 10000

</td></tr><tr><td>

sn\_cdm.max\_allowed\_cdi\_per\_library

</td><td>

The maximum number of CDIs allowed per shared component library. If the number is exceeded, further upload of config data via the REST APIs is blocked.

 Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command:

 ```
new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications();
Default: 10000
sn\_cdm.attachment.display\_mime\_typesFile types for which the content preview is available on the Preview pane. You can add additional MIME types to display in the Preview pane. However, the preview is not available for binary file MIME types, such as audio, image, and video. Default: `text/yaml,text/css,text/csv,text/html,text/javascript,text/plain,text/richtext,text/x-vcard,text/x-vcalendar,application/xml,application/javascript,application/json`
