An embodiment includes providing a request on demand for physical access to a page by a task of a node among a cluster of nodes, managing selective bypassing of waiting access requests to the page at intranode and internode levels in response to the request on demand, and handling requests for page ownership to prioritize a request on demand. Further included are determining whether another node holds a lock on the page and identifying an access type for the waiting access requests in order to coordinate transfer of the lock to the node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"On demand locking of retained resources in a distributed shared disk cluster environment","description":"Systems, methods, computer program product embodiments are provided for locking retained resources of database information in a distributed shared disk cluster environment.
