Editing IBM DevOps Code ClearCase (section)

== Infrastructure ==

The [[database]] system that ClearCase uses is RDM Embedded from Raima. In ClearCase terminology, an individual database is called a ''VOB'' ('''V'''ersioned '''O'''bject '''B'''ase).<ref>{{Cite web |title=Versioned object bases (VOBs) |url=https://www.ibm.com/docs/en/clearcase/10.0?topic=administration-versioned-object-bases-vobs |access-date=2024-05-13 |website=www.ibm.com |language=en-us}}</ref> On this layer, maintenance takes place using Raima tooling. Around this layer, a set of interfaces with accompanying tools are used to manage the physical database system, which requires specific [[Database administrator]] skills.<ref>{{Cite news |title=IBM Rational ClearCase - Computer Science {{!}} Wiki eduNitas.com |url=https://wiki.edunitas.com/IT/en/114-10/IBM-Rational-ClearCase_19336_eduNitas.html |access-date=2024-05-13 |work=edunitas.com |language=id-ID}}</ref>

The most important service is the Atria location Broker Daemon (ALBD), which manages all (LAN) communication between computers. Beginning with version 7, the server platform runs Websphere Application Server with a server application called the Change Management Server (CM Server), which served ClearCase clients via the HTTP Protocol. (Before version 7 there was a web service by which users could access ClearCase via their browsers.) CM server has since been replaced by the ClearCase Remote Client Wide-Area Network Server (CCRC WAN server), which continues to be based on Websphere Application Server.
