ClearCase can run successfully in the AWS Cloud. AWS provides virtual machines and
other services that can be used to run ClearCase servers and clients. AWS EC2
instances support Windows and Linux OS versions that ClearCase also supports so a
complete ClearCase installation using those OS versions can be setup in AWS.
This preview is intended as a courtesy to clients, showing the ClearCase and ClearQuest development team’s current intent for the 2019A release. The 2019A release refers to an internal naming convention for our quarterly fixpack release.
A Source Code Management (SCM) tool is one of the most critical pieces of any software development organization’s tool suite. Selection, use, and potentially migration decisions can be “make or break” for some organizations. In some cases, the tool’s users may seem almost religious in their zeal for or against a given toolset. GIT is a currently-very-popular SCM solution created by the Linux Kernel team for their own use, and it has seen wide adoption. “Why aren’t we using GIT?” is an increasingly common question in organizations using proprietary SCM solutions such as ClearCase. This is particularly true when those organizations are looking to reduce costs.
We recently conducted a webinar that focused on our IBM ClearCase and IBM ClearQuest product roadmaps. This webinar was intended to give you direct insight into what features are being considered and what's coming next.
Register for this webinar and get direct insight into our new and improved IBM ClearCase and IBM ClearQuest product roadmaps.
The ClearTeam Explorer (CTE) plugin for Eclipse allows developers to work in their Eclipse environment within an IBM ClearCase (CC) controlled filesystem. In this discussion, I will assume that the IBM ClearCase environment is one that has been set up with IBM ClearCase UCM projects and components by your CC administrator. Also under assumption is that the development tool is Eclipse with the ClearTeam Explorer IDE plugins installed.
Being faster, breaking the silos, improve collaboration, etc. are not new requirements in IT, in fact they are all there for a long time. However, from time to time, we discover some ideas / methods to meet the demands, no matter how long they are playing around us. This is my view of DevOps, a kind of effort to address these challenges that can no longer be postponed.
When learning more about DevOps makes me wonder how IBM ClearCase (CC) can contribute to this area.
In January, we announced a beta for our DevOps Dashboard. In February, we released our second beta. Today, we are pleased to announce the availability of our third beta! If you have already registered for the beta, you should have received an email with a link to download beta 3. If you have not yet registered, head over to our registration page to sign up.
In an IBM ClearCase community, the permanent repository of software artifacts consists of one or more VOBs, which are located on one or more VOB servers.
VOB servers are especially sensitive to memory, because of the performance benefits of caching the VOB database. With more memory, the VOB server can hold more of the database in memory. As a result, it will have to access data from the disk less often, a process that is thousands of times slower than memory access. For the VOB host, the IBM ClearCase Administrator’s Guide recommends a minimum of 128 MB of memory, or half the size of all the VOB databases the host will support, whichever is greater. Heed the advice of the Administrator’s Guide: “Adequate physical memory is the most important factor in VOB performance; increasing the size of a VOB host’s main memory is the easiest (and most cost-effective) way to make VOB access faster and to increase the number of concurrent users without degrading performance.”
Each day, your development team likely performs many check-in or check-out operations from your IBM ClearCase versioned object bases (VOBs). Likewise, if a project has engaged a Continuous Integration process, many software builds may be queued and executed each day. Consider how many IBM ClearCase operations your team performs over the lifetime of a project, and it is easy to see how even a small improvement in the speed of these operations can save a significant amount of time.
