Xclock does not work after switch to another user

suppose that user1 can run xclock and after switch to user2 xclock does not work does not matter if user1 or user2 is root you need to import the following values from user1 to user2 For KSH Shell $user1:/> xclock $user1:/>su - user2 $user2:/> xclock Error: Can't open display: $user2:/>exit  $user1:/>xauth list hostname/unix:10  MIT-MAGIC-COOKIE-1  630b2e7a7a794022834b0783b6f471fa hostname/unix:11  MIT-MAGIC-COOKIE-1  dbdcd6d69b9b3002484c4ea1e29a2ad5 hostname/unix:12  MIT-MAGIC-COOKIE-1  745ca626d4ef81101ef744589b4cfb09 $user1:/>echo $DISPLAY localhost: 11.0   (Hint : choose the matching values)  $user1:/>su - user2  $user2:/>xauth add hostname/unix:11  MIT-MAGIC-COOKIE-1  dbdcd6d69b9b3002484c4ea1e29a2ad5   $user2:/>export DISPLAY=localhost:11.0 $user2:/> xclock For CSH Shell $user2:/>xauth add hostname/unix:11  MIT-MAGIC-COOKIE-1  dbdcd6d69b9b3002484c4ea1e29a2ad5 $user2:/>setenv DISPLAY localhost:10.0

Move a file system to another volume group

How to move FS to anotherVG UNMOUNT fs Copy the source logical volume to the desired volume group with the cplv command. For example, where myvg is the new volume group and mylv is the name of the user's logical volume, enter:        cplv -v myvg mylv This will return the name of the new logical volume, such as lv00. 2- To make a new JFS log, enter the following command, where myvg is the name of the new volume group, enter:        mklv -t jfslog  myvg 1 To make a new JFS2 log, enter:      mklv -t jfs2log  myvg 1 ** This new logical volume will need to be formatted with the logform command in order to function properly as either a JFS or JFS2 log. For example:        logform /dev/loglv00 Answer yes to destroy. 3-Change the filesystem to reference a log device that exists in the new volume group and the new logical volume with the chfs command. For example, where myfilesystem is the name of the user's filesystem, enter:        chfs -a dev=/dev/lv00 -a log=/dev/loglv00 /myf

Backup to a remote tape device

The scenarios is as follows: Machine A : We need to take an mksysb image on a tape. The tape should be bootable. The machine does not have access to a tape drive. Machine B: Does have access to a tape drive and is connected to machine A via LAN. Procedure: A bootable tape as a result of mksysb contains 4 records (set of data). BOS Boot Image - contains a copy of the system's kernel and device drivers needed to boot from the tape. mkinsttape Image ./image.data - holds the information needed to recreate the root volume group and its logical volumes and file systems. ./bosinst.data - contains the customizable install procedures and dictates how the BOS install program will behave. This file allows for the non-interactive installs. Dummy "Table of Content" used to make mksysb tapes have the same number of files as BOS install tapes. Steps: (our working directory on both servers will be /opt) Machine A: Create a bootable image on machine A: Code: bosb

Breaking mirrors on an existing mksysb

To restore a mksysb without mirroring. the following procedure can be used NOTE: Access to another AIX system and an AIX formatted diskette is required to perform this procedure.  All references to the tape device in the next section are as rmt0. On another AIX system, place the mksysb tape in the tape drive. Change the block size of the tape drive to 512 by running: chdev -l rmt0 -a block_size=512   Create a temporary directory in /tmp called newdata .   mkdir /tmp/newdata Change to the /tmp/newdata directory. Enter:   cd /tmp/newdata    Make sure that the tape is rewound. Enter: tctl -f /dev/rmt0 rewind    Restore the image.data file from the second image of the mksysb tape. Enter: restore -s2 -xqvf /dev/rmt0.1 ./image.data    Edit the /tmp/newdata/image.data file and make changes to each of the lv_data stanzas as in

Creating a mksysb without mirroring

Creating a mksysb without mirroring If the ability to retrun the mksysb is available, the following procedure will allow you to create a mksysb without preserving mirroring.  To create a new image.data file, run the following command:  mkszfile  Change into the / directory and vi the image.data file. Enter: cd / vi image.data  The following examples show an lv_data stanza of an image.data file. The first example is with mirroring, while the second example shows the edited version without mirroring. The lines that need changes are marked by --> and are boldfaced. In the second example, the changes are made to those lines.        To view and edit the file,enter:  vi image.data Example 1     lv_data:                 VOLUME_GROUP= rootvg                 LV_SOURCE_DISK_LIST= hdisk0                 LV_IDENTIFIER= 00000001113f3c62.5                 LOGICAL_VOLUME= hd2                 VG_STAT= active/complete                 TYPE= jfs                 MAX_

Installing and configuring the storage agent (AIX)

The storage agent must be installed on a client system that has connections to storage resources on the SAN. Before beginning this procedure: Verify that your system meets the hardware and software requirements. Be sure that you have the information recorded in the configuration-information work sheets. Close all existing Tivoli® Storage Manager products prior to installing the storage agent. Installation will stop if an active Tivoli Storage Manager process is detected. If this occurs, close all active Tivoli Storage Manager products and retry installing the storage agent. The storage agent honors the Tivoli Storage Manager server environment variables DSMSERV_CONFIG. The instructions in this section are shown using the Software Management and Installation Tool (SMIT). You can also use the Install and Update Software Manager (installm). To reduce workload and processing time and to optimize LAN-free performance, do not install the storage agent and the Tivoli Storag
