ASAP 3.0 Server Manual

configure database history to only retain data since the last cleanup time; for example,
every night at midnight. Or you can configure it to retain ASAP history for a longer
period of time, or indefinitely.
The ASAP Collect process is continuous. If a CPU fails, the backup Collect process
automatically takes over so database access is always available. The ASAP database
is a real-time normalized database and can be queried online. The ASAP product
subvolume includes Enform queries that allow batch-type queries of network
performance and operational status.
The statistics Collect server (ASAPCOL) process runs continually and manages the
ASAP database. It:
Creates and maintains ASAP structured files.
Maintains statistics sent to the Collect process from various Monitor processes.
Manages ongoing space management of active database files.
If you manually execute the ASAPCOL object file from a TACL prompt with a process
name of $APPDB, $CPUDB, $DSKDB, $NETDB, $SYSDB, $PCBDB, $EXPDB,
$FILDB, $PRODB, $RDFDB, $SPLDB, $TAPDB, or $TMFDB, it acts as an Enform
server rather than a Collect process. For information on how to use ASAPCOL as an
Enform server, see the ENFALL file in the ASAP distribution subvolume.
ASAPCONF Object File
The ASAPCONF file contains configuration information for the ASAP and ASAP
Extension subsystems. Before trying to start the ASAP and ASAPX subsystems, make
sure that they are properly installed.
ASAPDSK Object File
The ASAP Monitor starts the Disk SGP on its node if Disk is enabled. The ASAP
Statistics Gathering (ASAPDSK) Process collects availability information for the ASAP
for all nonphantom disk devices. ASAPDSK uses the Measure Programmatic Interface
to obtain raw disk counters from the disk process.
ASAPEXP Object File
The ASAP Monitor starts the Expand SGP on its node if Expand is enabled. The ASAP
Statistics Gathering (ASAPEXP) Process collects availability information for the
Expand line handlers. The utilization counters gathered include page faults, BCC,
Naks sent and received, and packets sent and received. The Expand SGP
communicates directly with the Expand Manager process to get Expand availability
information.
