It all works fine, but when I take a closer look there... (2 Replies)

Hi Thinkers,
On AIX 5.3, we have a monitor program that reads the log file and searching for a certain string pattern that we define(say "transactionException"), if it sees it then it will raise an alert by sending an email.
Because the log file XXX.log is rolling into XXX.log.0, XXX.log.1,... (2 Replies)

Hi all
I try to execute SSH commands on several hosts in a while-loop.
There seems to be a problem with file-handle, first cycle works correct but no other one will follow due to the while condition is false even that there are many more host entries (lines) in all_hosts.dat.

NAME
rgmanager - Resource Group (Cluster Service) Manager Daemon
DESCRIPTION
rgmanager handles management of user-defined cluster services (also known as resource groups). This includes handling of user requests
including service start, service disable, service relocate, and service restart. The service manager daemon also handles restarting and
relocating services in the event of failures.
HOW IT WORKS
The service manager is spawned by an init script after the cluster infrastructure has been started and only functions when the cluster is
quorate and locks are working.
During initialization, the service manager runs scripts which ensure that all services are clear to be started. After that, it determines
which services need to be started and starts them.
When an event is received, members which are no longer online have their services taken away from them. The event should only occur in the
case that the member has been fenced whenever fencing is available.
When a cluster member determines that it is no longer in the cluster quorum, the service manager stops all services and waits for a new
quorum to form.
COMMAND LINE OPTIONS
-f Run in the foreground (do not fork).
-d Enable debug-level logging.
-w Disable internal process monitoring (for debugging).
-N Do not perform stop-before-start. Combined with the -Z flag to clusvcadm, this can be used to allow rgmanager to be upgraded with-
out stopping a given user service or set of services.
