5 Cluster Properties

The following topics provide information about each property associated with the Cluster category in the wcs_properties.json file:

5.1 About the Properties in the Cluster Category

Properties categorized under Cluster are used to communicate with all the servers in a cluster when a WebCenter Sites system is installed in a cluster.

5.2 Properties in the Cluster Category

Table 5-1 provides a description for each of the properties in the JSON file that are associated with the Cluster category.

Table 5-1 Cluster Properties

Properties Description

Properties	Description
`ft.sync`	An identifier or value that defines the synchronizer key for clustered servers; for example, the DSN that cluster members use for their shared database. Each cluster member must have the same `ft.sync` value. When set to `true` or `yes`, sync is enabled and extra asset-level locking is in effect. This mode is intended for clustered editorial systems, as it uses an asset-locking mechanism designed for frequent changes to assets. When set to a value other than `true` or `yes`, sync is enabled but extra asset-level locking is not in effect. This mode is intended for clustered delivery systems, as it enables an asset-locking mechanism designed for infrequent changes to assets. Note: Oracle recommends that you specify a value for `ft.sync`. Default value: `mycluster` Legal values: `<string>` \| `<blank>`
`ft.usedisksync`	Specifies a shared file system folder to synchronize data across a cluster. Set this property to a valid folder when synchronization is turned on with the `ft.sync` property. For example, set it to a directory where you have read/write access. Default value: `<wcsites.shared>/clustersync`
`xcelerate.lockdir`	Specifies the directory path (including the final slash) to the directory where WebCenter Sites stores information about the locks that lock data during database operations. If this WebCenter Sites system is installed on a cluster, this directory must have write permissions for and be accessible to all cluster members. This value is set by the WebCenter Sites installation. Default value: `<wcsites.shared>/lock`

ft.sync

An identifier or value that defines the synchronizer key for clustered servers; for example, the DSN that cluster members use for their shared database. Each cluster member must have the same ft.sync value.

When set to true or yes, sync is enabled and extra asset-level locking is in effect. This mode is intended for clustered editorial systems, as it uses an asset-locking mechanism designed for frequent changes to assets.

When set to a value other than true or yes, sync is enabled but extra asset-level locking is not in effect. This mode is intended for clustered delivery systems, as it enables an asset-locking mechanism designed for infrequent changes to assets.

Note: Oracle recommends that you specify a value for ft.sync.

Default value: mycluster

Legal values: <string> | <blank>

ft.usedisksync

Specifies a shared file system folder to synchronize data across a cluster.

Set this property to a valid folder when synchronization is turned on with the ft.sync property. For example, set it to a directory where you have read/write access.

Default value: <wcsites.shared>/clustersync

xcelerate.lockdir

Specifies the directory path (including the final slash) to the directory where WebCenter Sites stores information about the locks that lock data during database operations. If this WebCenter Sites system is installed on a cluster, this directory must have write permissions for and be accessible to all cluster members.

This value is set by the WebCenter Sites installation.

Default value: <wcsites.shared>/lock
