published in the discussion forums earlier . New Tips
will be published in discussion forums and archived here.
- 1. Adding
additional swap space.
- 2. Prompt,Sort,
Sum,edit- some tips.

Running Solaris in 32 or
64 bit mode .
-

- Find
and
list the core files.
- List the
partitions using more than 70% of
-
disk partition space.
1. Running Solaris in
32 or 64 Bit mode
Finding the running mode
___________________
#isainfo -v
64-bit sparcv9 applications
32-bit sparc applications
Booting in 32 bit mode
_________________
ok> boot kernel/unix
# eeprom boot-file=kernel/unix
Booting in 64 bit mode
__________________
OK>boot kernel/sparcv9/unix
# eeprom boot-file=kernel/sparcv9/unix
...reboot the system
Edit /platform/platform-name/boot.conf uncomment line with the variable
named ALLOW_64BIT_KERNEL_ON_UltraSPARC_1_CPU set to the value true .
ALLOW_64BIT_KERNEL_ON_UltraSPARC_1_CPU=true
... reboot the system .
If diag switch is set
to true following needs to be set
_______________________________________
for 32 bit
# /usr/sbin/eeprom diag-file="kernel/unix"
for 64 bit
# /usr/sbin/eeprom diag-file="kernel/sparcv9/unix"
2. Removing
^M from unix text files
Using Perl :
Following command will change the orginal file itself so keep a backup
copy .
perl -pi -e "s:^V^M::g" existing_file_name
You won't see the Control V on typing but it is needed to generate control
character ^M.
Using sed :
sed -e `s/^V^M//g` existing_file_name > new_file_name
Using vi :
Open file in vi and enter the following at : prompt in command mode .
:%s/^V^M//g
3. Backup
commands - ufsdump , tar , cpio
ufsdump
1. Used for complete file system backup .
2. It copies every thing from regular files in a file system to special
character and block device files.
2. It can work on mounted or unmounted file systems.
Tar:
1. Used for single or multiple files backup .
2. Can't backup special character & block device files .
3. Works only on mounted file system.
Identifying the tape
device
dmesg | grep st
Checking the status of the tape drive
mt -f /dev/rmt/0 status
Backup file system using ufsdump
ufsdump 0cvf /dev/rmt/0 /dev/rdsk/c0t0d0s0
or
ufsdump 0cvf /dev/rmt/0 /usr
To restore a dump with ufsrestore
ufsrestore rvf /dev/rmt/0
ufsrestore in interactive mode allowing selection of individual files and
directories using add , ls , cd , pwd and extract commands .
ufsrestore -i /dev/rmt/0
Making a copy of a disk slice using ufsdump
ufsdump 0f - /dev/rdsk/c0t0d0s7 |(cd /mnt/backup ;ufsrestore xf -)
Backing up all files in a directory including subdirectories to a
tape device (/dev/rmt/0),
tar cvf /dev/rmt/0 *
Viewing a tar backup on a tape
tar tvf /dev/rmt/0
Extracting tar backup from the tape
tar xvf /dev/rmt/0
(Restoration will go to present directory or original backup path
depending on relative or absolute path names used for backup )
Backup using cpio
find . -depth -print | cpio -ovcB > /dev/rmt/0
Viewing cpio files on a tape
cpio -ivtB < /dev/rmt/0
Restoring a cpio backup
cpio -ivcB < /dev/rmt/0
Compressing a file
compress -v file_name
gzip filename
To uncompress a file
uncompress file_name.Z
or
gunzip filename
4. Setting
up ethernet card speed , duplex mode in Solaris
Command Line : Changes are lost
on system reboots .
- set the device instance (for multiport cards)
ndd -set /dev/hme instance 0
this makes the next commands apply to hme0.
- query parameters for the set instance:
ndd -get /dev/hme link_status 0 = link up, 1 = link down
ndd -get /dev/hme link_speed 0 = 10MBit, 1 = 100MBit
ndd -get /dev/hme link_mode 0 = half duplex, 1 = full duplex
ndd -get /dev/hme adv_autoneg_cap 0 = no autonegotiation, 1 = autoneg.
enabled
- set parameters, e.g.
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_autoneg_cap 1 to enable autonegotiation for hme0
2. Permanant Changes : changes are not lost on reboot.
edit the /etc/system file and add these parameters .The sequence number
matters.
set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0
Ehthernet mode setting in x86
is done in drivers .conf file.

5. One
Line Scripts
Finding out the
memory information on a HP Unix system
Total Memory :
-------------------
echo "selclass qualifier memory;info;wait;infolog"|cstm | grep
"Total Configured Memory"
All Memory Information , slots, modules etc.
---------------------------------------------
echo "selclass qualifier memory;info;wait;infolog"|cstm
List highest diskspace users in /home directory
sort -nr sorts the output in numerical reverse order giving highest at the
top .
du -k /home | sort -nr | pg
*Find and list the core files in /app01 directory . Replace directory
name(/app01 ) , file name (core) and command (ls -l ) to customize .
Print option prints the output . 2>/dev/null is to supress the error
messages in the output .
find /app01 -name core -print -exec ls -l {} \; 2>/dev/null
Removing core files :
find /app01 -name core -print -exec rm -f {} \; 2>/dev/nul
compressing Log files
find /logdir -name *.log -print -exec gzip {} \; 2>/dev/null
List the partitions using more than 70% of disk partition space .
$5 represants column number to be compared and 70 is the value to be
compared .
df -k | awk '$5 > 70'
