Collection of informix versions #su-informix informix> onstat- This way you can see the version of informix. 15. Dual machine maintenance command Run the following command on one machine to first pull up the cluster daemons of both nodes, Then it will automatically pull up the application. cmruncl; Or run the dual-machine daemon on the host first, and then join the standby node, Then come to make the application run on a node, then the specified node should be the host. cmruncl -n scp1; cmrunnode scp2; cmrunpkg -n scp1 -v scp_service; View the status of dual-machine cmviewcl -v; cmviewcl; cmquerycl; cmviewconf; Two-machine switch Method 1: You can stop the host cmhaltnode scp1 Method 2: You can switch applications manually cmhaltpkg -n scp1 -v scp_service (will stop applying scp_service from scp1 machine) or su-tellin stellin> kill_scp.sh or su-informix informix> onmode -kuy If the node after the host is switched to become a switchable node again, you must run the following command cmmodepkg e -n scp1 -v scp_service (application scp_service can switch back to scp1 node next time) Sometimes in order to diagnose the standby machine, the standby machine is specially set to a node that cannot run the application, such as cmmodepkg d -n scp1 -v scp_service (it is not possible to run the application scp_service on node scp1) 16. The location of the dual-machine configuration file #cd / etc / cmcluster / (configuration file cmcluster.asc of the dual-machine daemon) #cd / etc / cmcluster / scppkg / (Dual-machine application configuration files scppkg.asc, control.sh, scppkg.sh, one of these three files is used to specify the floating IP of the dual machine) 17. Location of the two-machine maintenance command #cd / usr / sbin / (use ls cm * to see all the execution commands about the two machines) 18. Dual machine configuration 》》 Configuration cmcluster.asc; Check the validity of the cmcluster.asc configuration file #cmcheckconf -v -C cmcluster.asc If the configuration is incorrect, there will be an error prompt, and then correct it according to the error prompt, The configuration file is not applied until it is correct #cmapplyconf -f -v -C cmcluster.asc If you feel that the configuration needs to be changed again after application, you can delete the configuration file #cmdeleteconf -v -c scp1 #cmdeleteconf -v -c scp2 》》》 Configuration file scppkg.asc, control.sh, scppkg.sh Check the validity of the three documents #cmcheckconf -v -P scppkg.asc If the configuration is incorrect, there will be an error prompt, and then correct it according to the error prompt, The configuration file is not applied until it is correct #cmapplyconf -f -v -C scppkg.asc If you feel that the configuration needs to be changed again after application, you can delete the configuration file #cmdeleteconf -v -c scp1 #cmdeleteconf -v -c scp2 Remarks: The deletion mentioned here is only used when the single machine needs to be diagnosed and the two machines are used. Otherwise, it is not necessary to be so responsible, and it only needs to be reapplied. It does not matter if the original deletion is not deleted. 18. Network configuration 》》》 First of all, the network cable must be connected correctly When configuring the network card for the minicomputer, you must first ensure that the driver for the network card has been Installed, use the following command to view. #lanscan If the status of the main network card and the additional network card are up, it means that the network card is available. And at this time, you must know which card is used as the data network card. This network card should have been determined when the HP-UX operating system was installed. For example, choose lan0 as the main data network card, and the address of the network card is generally During the installation of HP-UX, the device path has also been displayed, such as: 0/1/10/0, etc., or you can also see its path using the lanscan command. After guidance, you should remove the directly connected network cable from the network button Connect to the active HUB. Then the other two are spare network cards. You can also determine the location of the two based on the path of the device. After determining, you can connect one of the cards to the same network port of another machine with a crossover cable to make a heartbeat cable. . Then don't configure the address of another additional network card. We use it as a backup network card. We need to use a direct connection network cable to connect to the backup HUB from this port. It can also be used as a heartbeat network card. The backup network card can also be used as the backup network card of the data network card. On the HPL2000 series of machines, we can also see a network button on the data network card. This port is used as a console port. A console cable can be connected to it to configure the machine. 》》》 Let ’s configure the IP address # vi /etc/rc.config.d/netconf This file contains the configuration of all network card names, network card iP addresses, gateways, and subnet mask. When the machine restarts, it will automatically configure the network according to the configuration file. or #ifconfig lan0 133.64.48.91 255.255.255.192 #ifconfig lan1 129.9.168.120 255.255.255.192 》》》 Check the address of the network card #lanscan lan0 #lanscan lan1 Lan2 does not configure an address. 》》》 Commonly used diagnostic tools for network cards ping; lanscan; see if the network card status is "up" linkloop; (When using this command, you must first use lanscan to check the physical address of the network card, Because the subsequent parameter of this command is the physical address of the network card, this can simply determine the network cable and hub Is there a problem) 》》》 In the same network, the subnetmask should be consistent. 19. When configuring the cmcluster.asc of the two machines, the subnet where the IP address of the network card is located should be formulated #netstat -in (you can see the address of the network card, the subnet corresponding to the IP address, the gateway, the default route, whether there is a floating network card, whether it is a host) 20. Configure routing information Method one: It can be increased by modifying the /etc/rc.confg.d/netconf file, the next time it starts Will take effect. Method 2: You can use the command line to set: / usr / sbin / route add default 20.08.28.98 1 21. View routing information #netstat -an 22. Configure remote maintenance How to determine whether remote maintenance has been configured. Remote maintenance is configured through hardware. As long as the serial port for remote maintenance is not damaged, even if you reinstall it, the remote light on the front panel of the minicomputer will turn yellow and the yellow light will always It means that it is possible to remotely maintain the serial port normally. But we still need to configure remote maintenance through GSP. 》》》 Remote port configuration of minicomputer ctrl + b enter enter GSP> ca A dialog box appears. If you want to modify a parameter, you can modify it through this dialog box. The usual values ​​are: bitrate: 9600 flow control: software terminal type: vt100 modem protocol: CCITT modem bit rate: 9600 flow control: hardware mode transmit configuration: disable mode presence: always connected 》》》 Configuration on modem AT & F ATS0 = 1 AT & WO & Y0 Save and exit. Remarks: HP generally provides a special omnidirectional modem, the name is "Tian Chi Chi Zhou", The modem must be connected to the line port. 23. A super command #set_parms The parameters behind it can be as follows date_time: set time; ip_address: set the network card address; hostname: set the hostname; addl_netwrk: Set the gateway of the host. 24. Adding users and user groups Method 1: Use useradd and groupadd commands to add; Method 2: Modify the files / etc / passwd and / etc / group to achieve. 25. A useful tool is sam Various operations can be performed through sam, such as: management of users and user groups; management of logical volume groups and logical volumes; management of kernel parameters; 26. A useful diagnostic tool mstm You can use it to collect all hardware information, such as which memory sockets, How big is each existing memory module, you can also check several memory modules and so on. Examples of use: #mstm Select system (), and select Tools / information / information log on the menu You can see a lot of information about the hardware, such as: System Information for (scp1) HPUX Model Number ......: L2000 // The machine model is HP L2000 HPUX Model String ......: 9000/800 / L2000-44 Original Product Number: A5191A Current Product Number .: System Serial Number ...: (Unknown) Hversion ...............: 0x5c40 Sversion ...............: 0x491 Software Capabilities ..: 0x100000f0 PD CPU Information: Number of CPUs in the current Protection Domain = 2 // Two CPUs Cabinet 0; Cell 0; CPU Map cpu ------------------------------------------------- slot | 00 | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | 13 | 14 | 15 | ------------------------------------------------- state | a | | | | | | | | | | | | ------------------------------------------------- c-Configured (CPU powered on) d-De-configured (CPU powered off) a-Active (configured and processes running) Select memory, and select Tools / information / information log on the menu You can see information about memory, such as: -Information Tool Log for MEMORY on path 8- Log creation time: Wed Jul 3 17:05:47 2002 Hardware path: 8 Basic Memory Description Module Type: MEMORY Total Configured Memory: 1024 MB // You can see how much total memory is, 1G Page Size: 4096 Bytes Memory interleaving is supported on this machine and is ON.

Webconsole settings HP Secure Web Console configuration and maintenance HP's Secure Web Console provides system administrators with a Web-based, more convenient means of accessing the Console. The system administrator only needs to start the web browser on any PC that can ping the Web Console, and enter the IP of the Web Console to get the interface of the server Console. To configure Web Console, follow these steps: 1) Initialize the Web Console: 1 / Connect the Web Console to the local network. The preset IP address is 192.0.0.192. 2 / On your PC, run the following command: route add 192.0.0.192 Local_IP_address 3 / Make sure you can ping 192.0.0.192. 4 / Run a web browser on the PC and enter the URL: [url = http: //192.0.0.192/] [color = # 0000ff] http://192.0.0.192 [/ color] [/ url] To get the Web Console configuration menu. Enter the Admin Account username and password according to the menu prompts, and change its IP to the local office IP address (make sure that the IP is not duplicated) and subnet mask. 2) Use Web Console 1 / Using the serial port of the ordinary Console, one end is connected to the local console port of the server, and the other end is connected to the serial port of the Web Console. 2 / On the browser of the PC, enter the current IP address of the Web Console. Enter its LOGIN window, enter the Admin Account username and password created during configuration as required; then enter the server console interface, click the Access Console with the mouse, the black Console window appears on the right of the screen; click In / Out to enlarge the Console window . 36. The location of the demo process The file in /etc/rc3.d/ can pull up the process when the system starts. 37. Use of magnetic tape write: tar cvf / dev / rmt / 0m /temp/t.sql // Back up the t.sql file under the temp directory to tape 0m; read: tar tvf / dev / rmt / 0m // Read the content in tape 0m; Untar the tar file from the tape: tar xvf /dev/rmt/0m/aa.tar ./ ​​// Unzip the aa.tar file on the tape to the current directory; When using tape to start the machine, we can enter the startup path by hitting any key during startup. Then enter SEA (search) to search for the starting path, and then you can find the path of the tape, such as the tape path is On the 5th path, enter po 5 to start from the tape. 38.
