Lspv: To Number of hard drives in your system, typeLspv hdisk1: To find detailed information about For example: The next team will create, in the volume of the testvg group, jfs2 file system 10 MB with a point of installation /fs2 and with reading only permission:crfs-v jfs2 -g testvg -a size -10M -p ro -m /fs2 Chfs: change in file system size Eg: increase the size /usr file system by 100000 512-block, Blocks, Blocks Type: chfs -a size 1,000,000 /usr Mount: a team to display information about all the file systems currently installed:1. Mountain CD rom: mount -V cdrfs -o ro /dev/cd0 /cdrom2. Mount file system: mount/dev/fslv02 /test3. Unmounted file system: umount /test4. Mount the entire file system:mount a'all'Defragfs: defragment file systemLsps -a: the amount of dedicated paging space and in use to increase paging space:-You can use the chps-s command to dynamically increase the size of the paging space. For example, if you want to increase the hd6 size with 3 logical sections, you give the following command:I Reduce paging space:-You can use the chps-d command to dynamically reduce the size of the paging space. For example, if you want to reduce the size of hd6 with four logical sections, you give out the following command: 1) Few commands Find: Use the team to find, find all the files, but ignore the foo.txt $ find . -Type f (-iname .txt ! -iname foo.txt) To delete file add-delete or-exec your-delete-command-here option. $ find. -type f (-iname .txt ! -iname foo.txt -Delete To select folder or dirs to use -type d, in this example, find all folders and ignore Foo and bar folder : $ find . -type d (! -iname foo ! -iname bar) To remove folders, except foo and bar $ find . -type d (! -iname foo ! -iname bar -) -execdir rm-rfv - 2) Services (start/stop/status): Example: FTP service check: -- Service status check, all services - status --status-all -- Specific services - service vsftpd reboot and service vsftpd reboot and service vsftpd You can restart also twice) - service nfs reboot and service vsftpd status vsftpd stopped service vsftpd start vsftpd vsftpd for vsftpd: 3) Tar / zip In order to zip the catalog, the correct command will be $ resin -zcvf archive.tar.gz catalog / $ resin -zxvf archive.tar.gz Unpack and unpack archive in the current catalog you would use Uisng : : -

If you point out that in this area, it works every hour. If you specify No. 5 in the 2nd field, it works every 5 hours, as shown below. 0 //5 - /home/scripts/backup.sh Note: In the same way, use No/2 every 2 hours, No/3 for every 3 hours, 4 euros for every 4 hours, etc. in) Completing the job every 5 seconds Work cannot be used to schedule work at intervals of a second. i.e. you can't schedule a cron operation to run every 5 seconds. The alternative is to write a shell script that uses the sleep of 5 command every-5-seconds.sh s in it. $ cat every-5- seconds.sh!/bin/bash while true to do/home/oracle/scripts/backup.sh sleep 5 done now, perform this shell script in the background using nohup as shown below. This will keep running the script even after you logut out of the session. This will carry your backup.sh shell every 5 seconds. $nohup./every-5- seconds.sh and d) Execution work every 5th weekday This example is not about planning every 5 days. But it's for planning every 5th weekday. 5th field DOW (day of the week). If you point out that in this area, it works every day. To run every Friday, specify either 5 Fri in this area. The following example shows backup.sh every Friday at midnight. 0 0 - 5 /home/oracle/scripts/backup.sh (or) 0 0 - Fri/home/oracle/scripts/backup.sh You can either have a user number or an appropriate three-letter acronym for a weekday, as shown below. 0'Sun 1'Mon 2'Tue 3'Wed 4'Thu 5'Fri 6'Sat Note: Go into the habit of using Fri instead of 5. Please note that the number starts with 0 (not with 1), and 0 for the Sun (not Mon). 10) diff command : To compare the two files Ignore the white space when comparing. $diff sample1.txt sample2.txt 11) sort of team examples sort file in an ascendant order $ sort sample.txt - Sort the file in descending order $ sort -r sample.txt - Sort passwd file on the 3rd field. $ sort-t: -k 3n/etc/passwd over 12) Xargs team examples Copy all images on the external hard drive xargs -n1 -i cp /externaldrive/directory Search for all images of jpg in the system and archive it. find/-name .jpg-type f-print xargs-resin-cvzf images.tar.gz Download all URLs mentioned in URL.txt file Xargs wget -c 13) shows that the team will turn off the system and immediately disable the power. Turn off -h now shut down the system after 10 minutes. Turn off -h No10 Reboot system with a shutdown command. Turn off -r will now force a file system check during the restart. Shutdown -Fr is now 14) passwd examples of the team changing the password from the command line using passwd. This will prompt an old password followed by a new password. The $ Passwd Super user can use the passwd command to reset other passwords. This will not prompt the user's current password. - Passwd USERNAME Delete password for a specific user. The root user can disable the password for a particular user. Once the password is disabled, the user can log in without entering a password. e,g, s passwd applmgr - passwd -d USERNAME 15) uname command examples Uname team displays important information about the system, such as - kernel name, host name, kernel release number, CPU type, etc., sample uname output from the Ubuntu laptop shown below. $ uname -a Linux eh-uatdb1 2.6.32-279.el6.x86_64 #1 SMP Wed June 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux 16) Version OS a) Linux: $ cat/etc/redhat-release Linux eh-uatdb1 2.6.6. 32-279.el6.x86_64 #1 SMP Wed June 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux b) AIX: $oslevel -s 6100-06-05-1115 17) tail team print the last 10 lines of the default file. $A tail filename.txt $th. N number of lines from a file called filename.txt View View It is useful for viewing log files that continues to grow.

Accelerates transmission by compressing the transmitted bits. --Delete - Deletes files from target that no longer exist in the source system --statistics - provides a detailed summary of timings, bits, transferred, etc. -u-update skip files that are new on the receiver - at the site of the update of appointment files on the spot (SEE MAN PAGE) --app application data app app application application application for short files --app-check-as-app-check-as-app- to see the options ... -- Example to copy unspoted archives from the fra location of the target system: vi ShipArchives.sh '!/bin/bash DATE'date .%H%M%S' x' $$(ssh [email protected] date %d%m%y) y'$$#x, $y if rsync -avu-ignore-existing /u03/FRA/archivelog/' [email protected]:/u04/backup/onlinelogs/home/oracle/scripts/ShipLogs/Shipped_$DATE.log Echo No connection with DESTINATION fi In crontab: 00,15,30,45 - th/home/oracle/scripts/ShipArchives.sh Another example: use rsync (yap. ssh) to clone file systems of applications with the following switches. Its very quick for us to copy the source for the target. Make sure to copy the correct source directories; Referee: Cloning Oracle Apps Issue 12 with Fast Clone ID 406982.1 rsync -ahlprz --statistics--delete -e ssh $SourceDirectory/. $TargetApplMgr:$TargetServer:$TargetDirectory/, i.e. using ssh to copy from one server to another 23) Multiple commands based on AIX: a) To check memory swap: $ lsps -s Total Paging Space Percentage Used 17408MB 0% b) To test total memory/cores $lsconf Grep Memory Memory Size: 32768 MB Good memory size: 32768 MB Good memory size: 32768 MB Good memory size: 3 32768 MB and mem0 Memory $lsconf Grep Processor Processor Type: 64-bit $lsconf Grep Processor Processor Type: PowerPC_POWER7 CPU Implementation Mode: POWER 7 Processor Version: PV_7_Compat Number of Processors: 3 Processor Watch: 4284 MHz Model Implementation: Multiple Processor, PCI Bus Enter the following command: - bootinfo -K 64 d) To find the OS version and TL level (Technological level) : s 7100-03-03-1415 e) 3.To identify the supported core mode, enter a command similar to the following : - getconf KERNEL_BITMODE 64 f) UDP and TCP Kernel ephemera tcp_ephemeral_high No 65535 tcp_ephemeral_low No 32768 udp_ephemeral_high - 65535 udp_ephemeral_low - 32768 Following Values for Oracle 11gR2: The recommended value for tcp_ephemeral_low is 9000 Recommended for tcp_ephemeral_high is 65500 Recommended for udp_ephemral_low is 9000 Recommended value for udp_ephemeral_high is 65,500 In the previous example, TCP and UDP ephemeral ports are set up for the default range (32768-65536). If you expect your workload to require a large number of ephemeral ports, such as a high node count or heavy use of the Parallel Query, upgrade the UDP and TCP ephemeral port range to a wider range. For example: /usr/sbin/no -o tcp_ephemeral_low-9000 -o tcp_ephemeral_high-65500 /usr/sbin/no-p-o udp_ephemeral_low-9000 -o udp_ephemeral_high-65500 g) whether there is an Oracle inventory group: whether there is an oraInst.loc file, then exiting this command is similar to the following: cat /etc/oraInst.loc inventory_loc'/u01/app/oraInventory inst_group'oinstall h) Creation of Oracle Inventory Group If the oraInst.loc file does not exist, Then create an Oracle Inventory group using the following procedure: 1. Enter the following command: smit security 2.Select the appropriate menu items to create the Oracle Inventory group (oinstall). 3.Click F10 on the way out.
