NAME
capupgrade -- Recompute CPU utilization data.
SYNOPSIS
Default path:
•
Windows CMS: C:\Program Files\HP\Virtual Server Environment\bin\
capupgrade
•
HP-UX CMS: /opt/vse/bin/
capupgrade
DESCRIPTION
capupgrade is used to recompute the CPU utilization data after an upgrade of Matrix OE. A
new copy of the Performance Index Database, which holds server performance benchmarks, is
installed whenever you upgrade Matrix OE. The Performance Index Database is used in pre-scaling
the CPU utilization data that is stored for capacity planning. After a Matrix OE upgrade, some of
the data must be recomputed and re-scaled. This process can take a long time if there is a large
history of utilization data.
In order to reduce the downtime of the CMS, the recomputing task is performed after the rest of
the Matrix OE upgrade is complete and the CMS is back online.
Although new Capacity Advisor data is not collected while the recomputing process runs, the rest
of Matrix OE is available.
To recompute the utilization data, follow these steps:
1. Wait until the Matrix OE 7.3.1 upgrade is complete.
The time of day to perform the recomputing task is flexible. Pick a time when Capacity Advisor
data collection can be suspended.
2. Log in to the CMS console.
3. Navigate to one of the following locations, depending on the operating system:
•
Windows CMS: C:\Program Files\HP\Virtual Server Environment\bin\
•
HP-UX CMS: /opt/vse/bin/
4. Recompute the data:
•
Windows CMS: Run capupgrade.bat
•
HP-UX CMS: Issue the capupgrade command. No parameters are required
The recomputing process:
•
Stops Capacity Advisor data collection.
•
Determines the data to be recomputed
•
Copies the new Performance Index Database
•
Recomputes the pre-scaled data
•
Restarts the Capacity Advisor data collection service
Recomputing can take several hours to run, depending on the number of systems and the amount
of collected data. The text output from capupgrade provides an estimate of the time.
OPTIONS
Capupgrade command has no options.
