GDSCTL uses the following command syntax:Table 2-1 Object Keywords and Abbreviations for GDSCTLEnables or disables valid node checking for registration (VNCR) list for database registrationTo add, modify, and manage the Oracle Data Guard broker configuration. If you do not specify a name for the pool when you create it, then the name defaults to Ensure that you are connected to the Global Data Services catalog and add a pool, administered by a specific user, as follows: If you require only one Global Data Services region, then you do not need to add a region using these instructions.
The biggest stumbling block? If the specified name is not domain qualified, the service is created with the default domain name ".", however the shorter non-domain qualified name can be used with subsequent GDSCTL commands to manage the service. It is also required to restart all global service managers in this case. So, you may have a few parts of a framework already in place. That’s the essence of data governance. Virtually every organization put elements of a data governance framework in place to support different initiatives along the way. For example, in my first job, we wanted to automate the ordering of spare parts for manufacturing companies through an e-commerce portal. Run the following command on the host where you want the global service manager to run:After you add the global service manager to the Global Data Services framework, start the global service manager, as follows:Connect to the Global Data Services catalog using the Global Data Services pool or Global Data Services administrator credentials, for example:Run the following command in SQL*Plus while connected to the GDS catalog: Sure, some forward-thinking organizations – like the manufacturer I spoke to – viewed their Today, it's possible to tie data governance efforts to a variety of corporate drivers. The executive mentioned that her company was prepared to spend almost a year getting business and IT groups to agree on the rules in place before the migration to a new system even started.She said that they were going to “get the right people together to solve some thorny problems” and “spend time understanding what terms meant.” She didn’t have the words for it at the time, but her group was building a data governance framework.
The maximum length of a domain qualified global service name is 250 characters.An Oracle Net connect descriptor used to connect to a global service must contain a domain qualified service nameBefore starting services which run on administrator-managed databases, they must be modified for those databases to stipulate which instances should run the service. Global service manager servers at an earlier version than the catalog will continue to operate fully until catalog changes are made.Upgrade pool databases in any order, either before or after the global service manager and catalog database upgrades, at the discretion of the pool database administrator. The program ground to a halt due to bad data, and we lacked a framework to get different groups together to fix it.In 2003, I went to work for a data management company, and I began to realize (too late) that many of these problems were symptomatic of data issues overall. We are agile. You must install each global service manager on its respective host.The Global Data Services administrator installs the global service manager.
You must configure ONS manually to enable SSL. Other times, data governance is a part of one (or several) existing business projects, like compliance or MDM efforts.
It also points out that there are a number of areas where you may already have the underpinnings of a data governance framework in place – and how to exploit that to create a bigger program in the future.As a counterpart to the IT group, I learned how things that looked simple on the business side can be ridiculously complex from IT's point of view. You can use existing high availability technologies, such as Oracle RAC, Oracle Data Guard, and Oracle Clusterware, to protect the Global Data Services catalog. Please refer to the Database clients connect to database services using an Oracle Net connect string. No other Oracle software is required to install and run the global service manager.You can install the global service manager on a system where you have other Oracle products installed, but you must install the global service manager in a separate Oracle home directory. For high availability, Oracle recommends installing multiple (typically 3) global service managers in each region running on separate hosts.Oracle Universal Installer does not currently support installing software on multiple hosts. Oracle recommends that you use Oracle high availability features such as Oracle Real Application Clusters (Oracle RAC) and Oracle Data Guard to protect the Global Data Services catalog against outages.The Global Data Services catalog must reside on an Oracle Database 12If you create the Global Data Services catalog in an Oracle RAC database, then Oracle recommends that you set up Single Client Access Name (SCAN) for that database.The Global Data Services administrator who creates the Global Data Services catalog must have a user account on the The Global Data Services catalog must be protected for high availability and disaster recovery.Oracle recommends that the Global Data Services administrator does not directly connect to the catalog database, despite having a user account on the catalog database. The first character must be alphanumeric. That has led to the need for a data governance framework – an overarching approach to how you collect, manage and archive data in your enterprise.The best part? A global service cannot be created at a database if a local or global service with the same name already exists at that database.A global service name can contain alphanumeric characters, "_' and '.'. It is a best practice to subscribe to three ONS servers in each of the client's local and buddy regions.Load balancing and Fast Connection Failover (FCF) of client connections across the databases in a GDS configuration is supported by the Oracle database integrated clients, and requires that those clients be configured for FAN and FCF.
