You see a pop-up notification asking you to update your browser. What do you do? Update the software, ignore the alert or postpone it to a future date? If you tend to overlook such notifications, its time to reconsider.
Updates help to ensure that your software is secure. Server software such as cPanel offers auto-update feature to secure your server from vulnerability. But there are times this auto-update fails with a notification message ‘Last Attempt to Update cPanel & WHM was Blocked’ in WHM. This is a blocker!
A blocker is the main reason why cPanel & WHM update process fails. Blockers can be license errors, RPM database integrity errors, MySQL version incompatibility, low disk space, cPanel restrictions, etc. When faced with a blocker, the solution is to identify the type of the blocker and resolve it.
The MySQL replication team have been hard at work improving the features of MySQL replication. In this part, I’ll be talking about a few more features included in MySQL 5.5
There have been many advancements in MySQL 5.5, a majority of them have been towards improving performance and scalability. InnoDB is now the default storage engine, which provides higher levels of performance and reliability than MyISAM. InnoDB 1.1 that is, a rearchitected InnoDB with many performance and scalability features over and above the built-in InnoDB in 5.1 and before. The industry switch from increasing CPU clock speed, to increasing the number of cores, left MySQL with a number of bottlenecks that prevented it from taking advantage of the extra processing cycles made available. This is no longer the case with MySQL 5.5, which takes full advantage of SMP systems. One area however, that I feel will be of particular interest to web hosts, are the advances in database replication in MySQL 5.5.
