[[_clustering_db_lock]]
|
|
=== Serialized cluster startup
|
|
|
|
{project_name} cluster nodes are allowed to boot concurrently.
|
|
When {project_name} server instance boots up it may do some database migration, importing, or first time initializations.
|
|
A DB lock is used to prevent start actions from conflicting with one another when cluster nodes boot up concurrently.
|
|
|
|
By default, the maximum timeout for this lock is 900 seconds. If a node is waiting on this lock for more than the timeout
|
|
it will fail to boot.
|
|
Typically you won't need to increase/decrease the default value, but just in case it's possible to configure it in
|
|
`standalone.xml`, `standalone-ha.xml`, or `domain.xml` file in your distribution. The location of this file
|
|
depends on your <<_operating-mode, operating mode>>.
