Good evening all, I have a very interesting issue. I have an oracle database on unix and nt. The dba says that his delete process runs in 22 mins on nt. When I run the same delete process on unix, it run in an hour. I downloaded sarcheck to see what was going on. It told me abpout the autoup... (3 Replies)

hi,
I am trying to determine a 'rule of thumb' threshold for memory usage on different Solaris versions.
I know that prior to Solaris 8, "page scan rate > 300" can be used as a general rule of thumb to determine any memory shortages. Since Solaris 9 and 10 have a different memory handling... (2 Replies)
Dear all,
I have a solaris 10 server , which is running web applications and webspere also is available.
All the parameters like Virtual memory , swap , hard disk space and Cpu utilisation and I/o statistics are good , but still the server is slow.
It has 2 processores and 128 VPs.

Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.

We have a SPARC T4-1 server, running Solaris 11, and it's doing some pretty extensive parsing on roughly 100GB data set.
All was well still few weeks ago, when I was testing the performance, I was reaching rougly 50minute calculation times, and it was more or less expected performance.
Now... (0 Replies)
I have identical M5000 machines that are needing to transfer very large amounts of data between them. These are fully loaded machines, and I've already checked IO, memory usage, etc... I get poor network performance even when the machines are idle or copying via loopback. The 10 GB NICs are... (7 Replies)
Hi,
I need general tips for solaris 11 performance optimization.
For example - disable the unused services, etc.
Thanks,

nscd
nscd(1M) System Administration Commands nscd(1M)NAME
nscd - name service cache daemon
SYNOPSIS
/usr/sbin/nscd [-f configuration-file] [-g] [-e cachename, yes | no] [-i cachename]
DESCRIPTION
nscd is a process that provides a cache for the most common name service requests. The default configuration-file /etc/nscd.conf determines
the behavior of the cache daemon. See nscd.conf(4).
nscd provides caching for the passwd(4), group(4), hosts(4), ipnodes(4), exec_attr(4), prof_attr(4), and user_attr(4) databases through
standard libc interfaces, such as gethostbyname(3NSL), getipnodebyname(3SOCKET), gethostbyaddr(3NSL), and others. Each cache has a separate
time-to-live for its data; modifying the local database (/etc/hosts, /etc/resolv.conf, and so forth) causes that cache to become invali-
dated upon the next call to nscd. The shadow file is specifically not cached. getspnam(3C) calls remain uncached as a result.
nscd also acts as its own administration tool. If an instance of nscd is already running, commands are passed to the running version trans-
parently.
In order to preserve NIS+ security, the nscd service checks the permissions on the passwd table if NIS+ is being used. If this table cannot
be read by unauthenticated users, then nscd will make sure that any encrypted password information returned from the NIS+ server is sup-
plied only to the owner of that password.
OPTIONS
Several of the options described below require a cachename specification. Supported values are passwd, group, hosts, ipnodes, exec_attr,
prof_attr, and user_attr.
-f configuration-file Causes nscd to read its configuration data from the specified file.
-g Prints current configuration and statistics to standard output. This is the only option executable by non-root
users.
-e cachename, yes|no Enables or disables the specified cache.
-i cachename Invalidate the specified cache.
EXAMPLES
Example 1: Stopping and restarting the nscd daemon.
example# svcadm disable system/name-service-cache
example# svcadm enable system/name-service-cache
FILES
/etc/nscd.conf Determines athe behavior of the cache daemon

NOTES
The output from the -g option to nscd is subject to change. Do not rely upon it as a programming interface.
The nscd service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/name-service-cache
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
