Ello group,
I have general question about how the performance of server/client should be?
My server is able to answer about 650times per second. Is it good performance?
the apache on the same machine makes 1600/sec BUT there is nine instances of httpd daemon what makes 180/ sec /instance.

Hi,
i would like to ask if it is possible to get the server load on a solaris machine, but i don't want something like uptime (load average), iostat and vmstat. I would like to get something in percentage like CPU load in %, Disk usage in %, Ram usage in %.
I want to collect this data and to... (3 Replies)
There is a big problem with the server (VPS based on OpenVZ, CentOS 5, 3GB RAM). The problem is the following. The first 15-20 minutes after starting the server is operating normally, the load average is less than or about 1.0, but then begins to increase sharply% wa, then hovers around 95-99%.... (2 Replies)

Hi,
I am new registered user here in this UNIX forums.
I am a new system administrator for AIX 6.1. One of our servers performs poorly every time our application (FINACLE) runs many processes/instances. (see below for topas snapshot)
I use NMON or Topas to monitor the server utilization. I... (9 Replies)
Hi,
how can we define performance of a server (Windows or Unix or Linux) ?
If processes waiting for CPU (on queue) are usually more than 3 or 5 can we conclude that CPU is not enough for that usage ?
Thank you. (1 Reply)
We are wondering if we are facing performance issue in our server when running Informatica jobs. Two things to suspect:
cache memory never comes down even when Top shows > 99% used.
There is some contention io or network related or Cache is clogged

VLDB.DB0(5) AFS File Reference VLDB.DB0(5)NAME
vldb.DB0, vldb.DBSYS1 - Contain the Volume Location Database and associated log
DESCRIPTION
The file vldb.DB0 contains the Volume Location Database (VLDB), which tracks the location of all AFS volumes stored on file server machines
in the cell. The Volume Location (VL) Server (vlserver process) provides information from the database to Cache Managers when they need to
access AFS data.
The file vldb.DBSYS1 is a log file in which the VL Server logs each database operation before performing it. When an operation is
interrupted, the VL Server replays the log to complete the operation.
Both files are in binary format and reside in the /var/lib/openafs/db directory on each of the cell's database server machines. When the VL
Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its copy of the database matches
the copy on the other database server machines. If not, the VL Servers call on AFS's distributed database technology, Ubik, to distribute
to all of the machines the copy of the database with the highest version number.
Always use the commands in the vos suite to administer the VLDB. It is advisable to create an archive copy of the database on a regular
basis, using a tool such as the UNIX tar command.
