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 Sybase 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).

jConnect – the Sybase high-performance JDBC driver.

job
– a task performed by the scheduler in Sybase 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 Sybase 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 Sybase Control Center that manages and monitors a
particular Sybase product. SCC product modules are available for Adaptive Server, Data Assurance (a Replication Server
option), replication (Replication Server, Replication Agent, and Mirror Replication
Agent), Sybase Event Stream Processor, and 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 Sybase 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 Sybase
Control Center. Resources SCC can manage include Adaptive Server, Data Assurance Server,
Replication Server, Replication Agent, Mirror Replication Agent, Sybase Event Stream
Processor, Sybase IQ, and certain subcomponents.
Replication Server Data Assurance (DA) Option – the Sybase server program that compares row data and schema between two or more Adaptive Server databases and reports discrepancies. In Sybase 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 Adaptive Server database containing Replication
Server system tables. You can choose whether to store Replication
Server system tables on the RSSD or the SQL Anywhere (SA) ERSSD.

Server system tables. You can choose whether to store Replication
Server system tables on the RSSD or the SQL Anywhere (SA) 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 Sybase 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 Sybase
Control Center by mapping appropriate Sybase 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 Sybase
Control Center or created in the operating system or the LDAP directory
service to which Sybase Control Center authentication is delegated. You must
use an SCC-enabled account to log in to Sybase Control Center.
schedule
– the definition of a task (such as the collection of a set of
statistics) and the time interval at which Sybase 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 Open Servers exchange information.
an application protocol by which Open Clients and 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 a Sybase 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.
