Application is slow now. Please guide me how to solve it?
NMON Report shows full cpu usage.

Here im posting some server details.

Please help me out.

Can i DLPAR temporally ? Is there any temporary fix?

Thanks,

NAME

       icapd - Instant Capacity (iCAP) daemon.

SYNOPSIS

       icapd

DESCRIPTION

       The (formerly ) daemon is installed and started as part of the Instant Capacity software on all potential iCAP systems, and respawns itself
       if killed.  If this daemon is not running, other Instant Capacity commands fail.  The operations this daemon performs are vital in  keeping
       the  complexwide  view  of  the	Instant  Capacity  state current.  The following entry is added to /etc/inittab in order to have start and
       respawn itself:

       icap:23456:respawn:/usr/lbin/icapd # Instant Capacity daemon

       This daemon is not started on hardware that is not supported under the Instant Capacity program.  If is installed and running on  a  system
       with Instant Capacity components present (cores, cells, or memory), it sends daily asset report email to HP (if so configured), tracks tem-
       porary capacity, sends exception notifications, and maintains a healthy Instant Capacity state.

       For more information about the functions that performs for Instant Capacity systems, see the located at /usr/share/doc/icapUserGuide.pdf.

       The daemon reports errors via (see syslog(3C)).	Exception notification email is sent to root and to the system contact email address (con-
       figured via the command (see icapmodify(1M)).

       The  daemon  performs periodic operations based on the time of day.  The daemon is spawned by and gets its time zone specification from the
       /etc/default/tz file.  By default, the time zone specified in /etc/default/tz is EST5EDT.  You can specify which time zone the daemon  uses
       to interpret its current time by modifying the /etc/default/tz file.  For details about the time zone format, see environ(5).  A restart of
       the daemon is required before the new time zone value takes effect (that is, kill the process).
