--------------prstat----Once we have identified which resource is being exhausted, you can use prstat to identify which processes causing it.

The /etc/passwd contains one entry per line for each user (or user account) of the system. All fields are separated by a colon (:) symbol. Total seven fields as follows.

Generally, passwd file entry looks as follows

1. Username: It is used when user logs in. It should be between 1 and 32 characters in length.

2. Password: An x character indicates that encrypted password is stored in /etc/shadow file.

3. User ID (UID): Each user must be assigned a user ID (UID). UID 0 (zero) is reserved for root and UIDs 1-99 are reserved for other predefined accounts. Further UID 100-999 are reserved by system for administrative and system accounts/groups.

4. Group ID (GID): The primary group ID (stored in /etc/group file) 5. User ID Info: The comment field. It allow you to add extra information about the

users such as user's full name, phone number etc. This field use by finger command.

6. Home directory: The absolute path to the directory the user will be in when they log in. If this directory does not exists then users directory becomes /

7. Command/shell: The absolute path of a command or shell (/bin/bash). Typically, this is a shell. Please note that it does not have to be a shell.

-----------------------------------------------------

To creat a new group,dba,GID-241,

groupadd –g 241 dbathis command places the entry in the /etc/group ( we can also insert manually )

dba:x:241----------------------------------------------------------------------------------------------

useradd –u 210 –g dba –c “The RDBMS” –d /home/oracle –s /bin/ksh –m oracle (here oracle is the username & “The RDBMS “ is the name via which mails will be send.

home directory is /home/oracleshell used-Korn shellm option ensures that home directory is created if it does not already exists

this command places the entry in the /etc/passwd

oracle:x:210:240:The RDBMS:/home/oracle:bin/ksh

-d home-directory-pathThis is the new user’s home directory, typically /export/home/username

-mmake home directory and copy the default skeleton files (these files are located in /etc/skel directory).

-u uidThe uid (userid) is a number from 0 to 65535 which identifies the user on the system. uid 0 is reserved for root. If you don’t specify one, the next available uid will be used automatically.

-c “ Name via which mail will be sent”Comment field which usually contains the name of the user. Make sure you enclose the name in quotes if it contains a space.

-s /path/to/shellThe shell to use. If you don’t specify this, it will default to /bin/sh. Make sure you specify the fully qualified path.

So, putting it together, a typical addition of a user named fred would be:

useradd -d /export/home/fred -m -s /bin/ksh -c "Fred Smith" fred

It’s a smart idea to run pwck (passwd check) whenever you make a change to the /etc/passwd file (as when adding or chaning a user). This program will identify any problems with the passwd file. If it doesn’t tell you anything, then you are in good shape.

Finding OS release and Kernel info

Sometime you need to determine what release of the OS are you running and other useful information that comes with that, like architecture, installation date, etc.

I'll mention four ways I use the most, it may be some other ones ... See /etc/release file - looks something like (easy to find update version, like

"update 7" and when it was assembled): o Solaris 10 5/09 s10s_u7wos_08 SPARC o Copyright 2009 Sun Microsystems, Inc. All Rights Reserved. o Use is subject to license terms. o Assembled 30 March 2009

Check info of SUNWsolnm (Solaris Naming Enabler) package - pkginfo -l SUNWsolnm (easy to see architecture, version, installation date)

o PKGINST: SUNWsolnm o NAME: Solaris Naming Enabler o CATEGORY: system

o ARCH: sparc o VERSION: 10,REV=2009.03.30.12.13 o BASEDIR: / o VENDOR: Sun Microsystems, Inc. o DESC: Enable Solaris Name in /etc/release file o PSTAMP: re29796 o INSTDATE: Jun 17 2009 14:06 o HOTLINE: Please contact your local service provider o STATUS: completely installed o FILES: 2 installed pathnames o 1 shared pathnames o 1 directories o 1 blocks used (approx)

Baseboard management controllerFrom Wikipedia, the free encyclopedia  (Redirected from Baseboard Management Controller)Jump to: navigation, search

A baseboard management controller (BMC) is a specialized microcontroller embedded on the motherboard of a computer, generally a server. The BMC is the intelligence in the Intelligent Platform Management Interface (IPMI) architecture. The BMC manages the interface between system management software and platform hardware.

Different types of sensors built into the computer system report to the BMC on parameters such as temperature, cooling fan speeds, power status, operating system (OS) status, etc. The BMC monitors the sensors and can send alerts to a system administrator via the network if any of the parameters do not stay within preset limits, indicating a potential failure of the system. The administrator can also remotely communicate with the BMC to take some corrective action such as resetting or power cycling the system to get a hung OS running again. These abilities save on the total cost of ownership of a system.

Physical interfaces to the BMC include SMBus busses, an RS-232 serial console, address and data lines and an Intelligent Platform Management Bus (IPMB), that enables the BMC to accept IPMI request messages from other management controllers in the system.

A direct serial connection to the BMC is not encrypted as the connection itself is secure. Connection to the BMC over LAN may or may not use encryption depending on the security concerns of the user.

The system controller has a 128K error buffer, which is copied to /var/adm/messages. If the system has been down for any reason, the buffer gets flushed to /var/adm/messages at boot time (see page 82). There is no loghost facility for sending SC information to an external loghost.

Backup and Recovery

This section provides information needed for backup and recovery administration of the AIR server.

The AIR system is called a static node, meaning that data that is held by the AIR system does not change very often and in case there is a need to restore the data, a dump from the night before will not cause any major loss of data.

Backups are performed on a daily basis. The tape will be ejected after completion and must be replaced for the next backup the day after. The first session on the

tape contains crucial files for the restoration process and can also serve as an identification and index for the rest of the tape.

6.1   File System Backup

During the installation a cronjob is created on each server to make the script run automatically, every night, like this:

00 2 * * * /opt/EABcsutls/backup/backup.sh

The example reads:

Run the backup script at 02.00 every day.

To check the root cronjobs, use the UNIX command crontab while being root:

# crontab -l

If you want to change the cronjob type:

# EDITOR=vi; export EDITOR

# crontab -e

The first five fields of the crontab entry indicate at what time the job should run. The order is like this: minute (0-59), hour (0-23), day of the month (1-31), month of the year (1-12), day of the week (0-6 with 0=Sunday). The * means all legal values.

6.1.1   AIR Backup Logfile

While executing the backup you can view the progress by executing the following command from any available shell on the server:

# tail -f /var/log/backuplog

After the backup is complete the logfile is renamed to /var/log/backuplogX, where X corresponds to the current day of the month. This way backup-logs for a month back will be available in the /var/log directory. You can view these files if you want to check the result of an earlier backup.

The printout below is an example of how the printout can look like:

Backup started at: Mon Mar 1 02:00:00 CET 2004

ToC generated, the following sessions will be on tape

All sessions written (except the log) at:Mon Mar 1 02:07:00 CET 2004Backup completed at: Mon Mar 1 02:07:00 CET 2004Note:  

The warning from tar, (the line starting with tar: ./devices/), when backing up the root file system can be ignored. The file path which is ending with /st@4.0:cn will not be included in the backup but will be recreated during restore.

6.2   File System Recovery

To complete a restore of the AIR server a successful backup of the AIR server has to be performed. If a shutdown is needed before the recovery, see Section 5.4 for instructions.

Note:   Always contact your local Ericsson support organization before restoring the AIR system.

To perform a recovery of the root file system, see Section 6.2.1.

6.2.1   Restoring File System from Tape

To perform a file system recovery follow the instruction:

1. Insert the installation DVD in the DVD-ROM drive.

Either the DVD labeled VS/AIR/AF Installation Media (sun4u) or the DVD labeled VS/AIR/AF Installation Media (sun4v) may be used for booting.

2. Connect to the console, see Section 8 to get instructions in how to access the console on different hardware.

3. Boot to single-user mode, using the CD.

ok boot cdrom -s

4. Wait for result printout.

INIT: SINGLE USER MODE

5. Change directory to /tmp.

# cd /tmp

6. Rewind the magnetic tape.

# mt -f /dev/rmt/0cn rewind

7. Unpack the restore.sh script and tape contents file.

# tar -xf /dev/rmt/0cn

8. Run the restore.sh script.

# ./restore.sh

The server will now be restored from tape.

9. Wait for therestore to complete, this can take up to 120 minutes.

Progress and result of the restore procedure is printed on the server console.

10. If an Account Finder (AF) is present, complete the file system recovery by performing an restore of AF data.

Follow the instructions in AF documentation..

The Sun Fire V480 supports up to four UltraSPARC III processors and up to 32 GB RAM. Each server is equipped with four CPUs and 8 GB RAM each.

8.1.1   Mounting

The Sun Fire V480 servers are rack mounted in one cabinet. It is possible to mount several Sun Fire V480 servers into the same cabinet.

8.1.2   Server Hardware

The Sun Fire V480 supports up to four UltraSPARC III processors and up to 32 GB RAM. Each server is equipped with four CPUs and 8 GB RAM each.

The basic system includes two power supply units, each with two internal fans. The power supplies are plugged directly into one power distribution board. One power supply provides sufficient power for a maximally configured system. The second power supply provides "1 + 1" redundancy, allowing the system to continue operating if the first power supply fails. A power supply in a redundant configuration is hot-swappable.

The Figure 5 shows the front of the Sun Fire V480 server.

Figure 5   Sun Fire V480 Front View

The Figure 6 shows boards and devices that are seen from the rear view of the Sun Fire V480.

Figure 6   Sun Fire Rear View

8.1.3   Console Access

The Sun Fire V480 server provides a serial communication port, which can be accessed through an RJ-45 connector located on the system's back panel. The system can be administered either from a terminal connected to this connector or from a remote workstation connected to the Remote System Control (RSC) card over the public LAN. Once the RSC is configured it is no longer possible to use the serial port for console access.

To gain access the console, use the following procedure:

1. Connect to the RSC port either over the network or to the RSC serial port. 2. Please login:

Enter root as the login name.

3. Please Enter password:

Enter the password for the root-user defined on the RSC.

4. Type the following to connect to the console:

rsc> console

Note:   The RSC Ethernet interface does only support a 10 Mbit/s connection.

The average I/O size during the interval can be computed from kr/s divided by r/s.

kw/s kilobytes written per second

The average I/O size during the interval can be computed from kw/s divided by w/s.

wait average number of transactions waiting for service (queue length)

This is the number of I/O operations held in the

device driver queue waiting for acceptance by the device.

actv average number of transactions actively being ser- viced (removed from the queue but not yet com- pleted)

This is the number of I/O operations accepted, but not yet serviced, by the device.

svc_t average response time of transactions, in mil- liseconds

The svc_t output reports the overall response time, rather than the service time, of a device. The overall time includes the time that transac- tions are in queue and the time that transactions are being serviced. The time spent in queue is shown with the -x option in the wsvc_t output column. The time spent servicing transactions is the true service time. Service time is also shown

with the -x option and appears in the asvc_t out- put column of the same report.

%w percent of time there are transactions waiting for service (queue non-empty)

%b percent of time the disk is busy (transactions in progress)

wsvc_t average service time in wait queue, in mil- liseconds

asvc_t average service time of active transactions, in milliseconds

wt the I/O wait time is no longer calculated as a percentage of CPU time, and this statistic will always return zero.
