Given procedure helpful for applying Firmware and OS patches for Solaris 9 Before starting the patching Ensure all system files have up to date backup. I.  Installation of OBP patches: 1. Verify system hardware level.    # uname  -a    SunOS LABSEVER 5.9 Generic_118558-39 sun4u sparc SUNW, Sun-Fire-V440 2. Copy the appropriate OBP patches to the server under /var/tmp/OBPpatches. 3. Unzip the OBP patches    #unzip <patch-id.zip> 4. Verify the server for existing OBP level    #prtdiag  -v |grep –i OBP And compare the patch level with the new OBP patch level info available in /var/tmp/OBPpatches/<patch number>/README.<patch number>.   If the existing level is lower than the update available, update the server with OBP   patches. Otherwise you can skip the OBP patches. 5. It is good practice to apply any OS/OBP patches in Single user mode (need console logi...

Topic : What is liberty Profile in WAS? and its features Explanation: The Liberty profile is a lightweight, simple to use, yet powerful, application server for lightweight web production server , OSGi, and mobile applications. Extremely fast restart times coupled with its small size and ease of use make the Liberty profile a great option for building web apps that do not require the full Java EE environment of traditional enterprise application server profiles. Features: 1.Simple Configuration (only one simple config file server.xml for all configurations) 2. Rapid Server Restart (less then 5 seconds) 3. It supports integrated  tools like(Maven/Eclipse). 4. dynamically extendible. 5. Supports light weight Cluster Management. 6. Fidelity to traditional WAS.  7. Web Profile Certified. 8. Memory foot print is < 60 MB 9. Profile is dynamic (switch parts of the server on and off with out restart) 10. Be installed and managed separately from a...

Issue: Circular Log is deleted by the user by mistake which causes the queue manager not able to start Solution: Restore the log file from back up and start the qmgr. it should work WorkAround: If there is no backup the workaround to get the queue manager running is 1. backup /var/mqm/log/<ORI_QMGR> 2. create the dummy qmgr with the similar log description as in the <ORI_QMGR>for this refer the /var/mqm/qmgrs/<ORI_QMGR>/qm.ini 3. crtmqm <DUMMY_QMGR> -lp 3 -ls 2 -lp 1024 -lc 4. copy /var/mqm/log/<DUMMY_QMGR>/active and amqhlct.ifh to /var/mqm/log/<ORI_QMGR>        cp  /var/mqm/log/<DUMMY_QMGR>/* /var/mqm/log/<ORI_QMGR>/ 5. ensure all semphores for <ORI_DMGR> are cleared 6.strmqm <ORI_QMGR> 7. you can remove <DUMMY_QMGR> if not required.

Issue:   A composition unit with name <APP_NAME> already exists.Select a different application Name Solution: Sometimes this error will come even after deleting the application from WAS. Remove the application references from the below paths. <WAS_INSTALLATION_PATH>/Dmgr01/config/cells/<CELL_NAME>/blas/ <WAS_INSTALLATION_PATH>/Dmgr01/config/cells/<CELL_NAME>/cus/ removing the application references from the above paths will resolve the problem

Topic : Set the default profile when multiple dmgr profiles are there. Go to <WAS_INSTALLATION_PATH>/properties/fsdb/_was_profile_default modify the default.sh file to point to the required profile. This default profile setting can be useful when you have multiple number of profiles and want to deploy the application in particular profile through scripts.  <WAS_INSTALLATION_PATH> can be like /opt/ibm/WebSphere/AppServer

LVM_Operations.md The following steps will provide an idea of how to perform basic operations on Linux (RHEL) LVM. Creating VG Scan for the new disk. For that first you need find out which host bus to scan. # grep mpt /sys/class/scsi_host/host?/proc_name If the disk properly attached, it should return like below. /sys/class/scsi_host/host6/proc_name:mptspi Here you need to rescan host6 #echo "- - -" > /sys/class/scsi_host/host6/scan Here "- - -" means to scan All channels All controllers All LUNs Cross verify if the disk was allocated to any VG #vgdisplay -v |grep -i diskname This is just to re-confirm you are playing around with Correct/New disk. Create new PV using following command. #pvcreate <newdisk> Create VG #vgcreate -s <Size of PE> <VG_name> <Disk> Eg: #vgcreate -s 32M vg01 /dev/sdb verify the VG and attribures #vgdisplay <Vg_Name> Create LV Create a LV #lvcreate -l ...
