Hi
I'm a little rusty with HACMP, but wanted to find out if it is possible to remove a disk heartbeat network from a running HACMP cluster.
Reason is, I need to migrate all the SAN disk, so the current heartbeat disk will be disappearing. Ideally, I'd like to avoid taking the cluster down to... (2 Replies)

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library.

XNBD-BGCTL(1) General Commands Manual XNBD-BGCTL(1)
NAME
xnbd-bgctl -- Control a server running xnbd-server(8) through its control socket
SYNOPSIS
xnbd-bgctl [--cache-all] [--cache-all2] [--query] [--reconnect REMOTE_HOST REMOTE_PORT] [--shutdown] [control_socket]
DESCRIPTION
With the xmbd-bgctl command you can connect to a xnbd-server control channel and instruct it to act as directed. You may pass an argument
to the control program which is then forwarded, on your behalf, to the server instance.
OPTIONS
The following options are supported:
--cache-all
If the remote xnbd-server acts as proxy server, this command intstructs the controlling xnbd-server instance to cache all blocks
on its associated block disk. Upon completion the controlled xnbd instance holds all data from the origin instance and it is no
longer necessary to act as proxy.
--cache-all2
This command is identical to cache-all but detaches the process from the terminal and is hence using a dedicated connection for
data transfer.
--query This command retrieves completion statistics from the proxy server instance. It returns the number of cached blocks on the
server.
--reconnect
This command recovers from a lost connection by re-establishing connectivity with the origin server. This command expects two
additional arguments, the REMOTE_HOST, and the REMOTE_PORT you want to connect to, to recover from a disconnected session.
--shutdown
This command stops the proxy server and restarts the target server. All client sessions are preserved.
POSITIONAL ARGUMENTS
The following positional options are supported:
CONTROL_SOCKET
The Unix domain socket, the xnbd-server(8) program is listening on.
