The Question is:
What causes remote locking? and how to investigate it further
The Answer is :
Remote lock requests are a component of the OpenVMS Distributed
Lock Manager (DLM), and are synchronization operations that involve
other cluster members.
For a tool shipped with OpenVMS that can monitor the DLM, please see
the MONITOR utility; please specifically see the MONITOR DLOCK command
documentation. Also please see the AMDS tool or the Availability
Manager tool -- these two tools are licensed with and are shipped
in directories on the OpenVMS CD-ROM distribution kit, though are
separately installed. The OpenVMS Wizard strongly encourages that
one of these two tools be installed, configured, and be used by
every OpenVMS site. Both tools have DLM-related capabilities.
For detailed (internal) information on locking, please see the
Internals and Data Structures manual. For user- or programmer-level
documentation on the DLM, please see the Programming Concepts manual
and the system services reference entries for services such as $enq,
$deq, and $getlki. For more information on clustering and on system
performance, please see the clustering manuals and the performance
manual.
Please contact the organization that supports the Robomon package
for assistance with Robomon. As stated in the introduction to
asking a question of the OpenVMS Wizard, the OpenVMS Wizard is
not in a position to provide any particular detailed information
on, nor to provide support of, third-party products.
