While you are creating a blog, whether it’s a page on a business site or your site is a blog—is a great way to interact with readers and drive traffic to your site. But because so many sites do have blogs, it’s important that yours stand out. Excellent content is, obviously, important. Readers won’t keep coming back to a blog that’s poorly written or seldom updated. But even the best blog posts will get more attention if the layout surrounding them is visually appealing, memorable and easy to navigate. Here are six tips to make that happen. First thing to Make posts inviting. If you have a blog with a lot of posts, it’s OK to put some of the copy under a cut. But make sure that what readers can see is enough to make them want to click through. Adding a subhead to the title can help clarify exactly what the post is about. Not too Complicated Layout: A great blog layout should never get in the way of the actual blog posts. Avoid layering too many elements into the page. If you are lookin...

we have recently Deployed the  Oracle Linux Virtualization Manager 8.7 version on HP ProLiant Server, I would like to make a process what we have followed to bring up the Physical Oracle Linux Virtualization server. This  similar to ESXI in VMware server, on ESXI we will install the ESXi with ISO/Network Installation Methods. We have downloaded the Oracle Linux Virtual Manager 8.7 OS ISO from Oracle Site. Copied to the remote terminal server. Datacenter Team has racked the servers and  provided the ILO IP's and User Names to Proceed with Infra Activities. We have tried to Login to Consoles of the servers , we had a firewall issue to access to consoles over the https. we worked with Network team to Open the ports  at firewall level, then we were able to login & Access the Consoles. Step 1 - we have done with Changing the Default ILO Credentials to standard Credentials as per the Company standards. Step 2 - Next step we have Downloaded the HP Provid...

Saving Domain Configurations for Future Rebuilding The basic process is to save the resource constraints information for each domain into an XML file, which can then be re-issued to the Logical Domains Manager, for example, after a hardware failure to rebuild a desired configuration. Restore a Domain Configuration From an XML File ( ldm add-domain )  works for guest domains, but not for the control ( primary ) domain. You can save the  primary  domain's constraints to an XML file, but you cannot feed the file back into the  ldm add-domain -i  command. However, you can use the  ldm init-system  command and the resource constraints from the XML file to reconfigure your  primary  domain. You can also use the  ldm init-system  command to reconfigure other domains that are described in the XML file, but those domains are left inactive when the configuration is complete. The method that follows does not preserve actual bindings, only the ...

Find full or half duplex speed You can use dmesg command to find out your duplex mode: # dmesg | grep -i duplex Output: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 ethtool command Uss ethtool to display or change ethernet card settings. To display duplex speed, enter: # ethtool eth1 Output: Settings for eth1:         Supported ports: [ TP ]         Supported link modes:    10baseT/Half 10baseT/Full                                 100baseT/Half 100baseT/Full                                 1000baseT/Full         Supports auto-neg...

Linux Interview Questions & Answers:   Q:1 Why LVM is required ? Ans: LVM stands for Logical Volume Manager , to resize filesystem’s size online we required LVM partition in Linux. Size of LVM partition can be extended and reduced using the lvextend & lvreduce commands respectively. Q:2 How To check Memory stats and CPU stats ? Ans:  Using ‘free’ & ‘vmstat’ command we can display the physical and virtual memory statistics respectively.With the help of ‘sar’ command we see the CPU utilization & other stats. Q:3 What does Sar provides and at which location Sar logs are stored ? Ans: Sar Collect, report, or save system activity information. The default version of the sar command (CPU utilization report) might be one of the first facilities the  user  runs  to  begin system  activity investigation, because it monitors major system resources. If CPU utilization is near 100 percent (user + nice + system), the workload sampled ...
