Glossary: SAP Control Center for Data Assurance

Definitions of SAP Control Center terms related to Replication Server Data Assurance (DA) Option.

availability – indicates whether a resource is accessible and responsive.
collection – a named, predefined set of key performance indicators for which values are collected from monitored servers at the same time. Collections supply the performance and availability data shown on SAP Control Center screens and charts. Use the scheduler to view a list of collections and to control which collections run, how often they run, and the length of time for which they run.
connection profile – information required to establish a database connection.
database – a set of related data tables and other objects that are organized and presented to serve a specific purpose.
Data Assurance job – a row comparison or a schema comparison job that defines how a compareset is compared and when.
Data Assurance system database (DASD) – the DA server database that stores system and configuration settings.

the DA server database that stores system and configuration settings.

Data Transfer Stream (DTS) – an application protocol used by DA agent during a comparison to stream data.

an application protocol used by DA agent during a comparison to stream data.

event – an activity in the system, such as a user logging in, a service starting or stopping, or a condition changing. Use the alerts feature to detect and notify you about system events.
heat chart – a graphical view of resource availability and selected performance and status metrics for all the registered resources in the current perspective.
inconsistent row – a table row that is present both in primary and replicate databases, but has different values for one or more of the columns being compared.
Java Database Connectivity (JDBC) – an application program interface (API) that allows Java applications to access multiple database management systems using Structured Query Language (SQL).

an application program interface (API) that allows Java applications to access multiple database management systems using Structured Query Language (SQL).

jConnect – the SAP high-performance JDBC driver.

the SAP high-performance JDBC driver.

job – a task performed by the scheduler in SAP Control Center.
key performance indicator (KPI) – a single metric used to evaluate the status or performance of a monitored resource. A KPI value can be a state (such as running, error, or stopped) or a numerical value. KPIs are grouped into collections (and also, for some product modules, into key performance areas, or KPAs). KPI values are collected by scheduled collection jobs and appear on monitoring screens and in the statistics and heat charts. Examples of KPIs are resource state and CPU usage.
managed resource – see resource.
missing row – a table row that is present in the primary, but not in the replicate database.
orphaned row – a table row that is present in the replicate, but not in the primary database.
perspective – a named tab in SAP Control Center that displays information related to a collection of managed resources (such as servers) and a set of views associated with those resources. The views in a perspective are chosen by users of the perspective. You can create as many perspectives as you need, and customize them to monitor and manage your resources. Perspectives allow you to group resources in ways that make sense in your environment—for example by location, department, or project.
primary key – a set of table columns that uniquely identifies each row.

a set of table columns that uniquely identifies each row.

product module – a plug-in component of SAP Control Center that manages and monitors a particular Sybase product. SCC product modules are available for SAP ASE, Data Assurance (a Replication Server option), replication (Replication Server, Replication Agent, and Mirror Replication Agent), SAP Sybase Event Stream Processor, and SAP Sybase IQ.
replication – a process by which the changes to the data in one database—including creation, updating, and deletion of records—are also applied to the corresponding records in another database.
repository – a database in SAP Control Center that stores information related to managed resources, along with user preference data, operational data, and performance statistics.
resource – a server, agent, or other entity that can be monitored or administered by SAP Control Center. Resources SCC can manage include SAP ASE, Data Assurance Server, Replication Server, Replication Agent, Mirror Replication Agent, SAP Sybase Event Stream Processor, SAP Sybase IQ, and certain subcomponents.
Replication Server Data Assurance (DA) Option – the SAP server program that compares row data and schema between two or more SAP® Adaptive Server® Enterprise (SAP® ASE) databases and reports discrepancies. In SAP Control Center, the product module that monitors and manages the Replication Server DA Option is called SCC for DA.

the SAP server program that compares row data and schema between two or more SAP® Adaptive Server® Enterprise (SAP® ASE) databases and reports discrepancies. In SAP Control Center, the product module that monitors and manages the Replication Server DA Option is called SCC for DA.

Replication Server system database (RSSD) – the SAP ASE database containing SAP Replication Server system tables. You can choose whether to store SAP Replication Server system tables on the RSSD or the SAP SQL Anywhere ERSSD.

the SAP ASE database containing SAP Replication Server system tables. You can choose whether to store SAP Replication Server system tables on the RSSD or the SAP SQL Anywhere ERSSD.

Remote Method Invocation (RMI) – a remote procedure call used for communication between DA server and DA agents.

a remote procedure call used for communication between DA server and DA agents.

SCC agent – a remote command and control agent for SAP Control Center that runs on a managed server. The SCC agent is installed automatically as part of the Sybase server.
SCC-enabled login account – a user account that has been granted privileges in SAP Control Center by mapping appropriate SAP Control Center roles. (Roles are typically mapped to a group to which the account belongs rather than to the account itself.) The user account and group can be native to SAP Control Center or created in the operating system or the LDAP directory service to which SAP Control Center authentication is delegated. You must use an SCC-enabled account to log in to SAP Control Center.
schedule – the definition of a task (such as the collection of a set of statistics) and the time interval at which SAP Control Center executes the task.
schema – the structure of the database.

the structure of the database.

Tabular Data Stream (TDS) – an application protocol by which Open Clients and SAP Open Servers exchange information.

an application protocol by which Open Clients and SAP Open Servers exchange information.

topology – a graphical representation of how the servers in an environment are connected to each other. It is a network diagram that provides a visual map of the availability of the environment.
view (SCC) – a window in an SAP Control Center perspective that displays information about one or more managed resources. Some views also let you interact with managed resources or with SCC itself. For example, the Perspective Resources view lists all the resources managed by the current perspective. Other views allow you to configure alerts, view the topology of a replication environment, and graph performance statistics.
