Troubleshooting guide

•
replicated transaction – a primary transaction that is replicated from a primary database
to a replicate database by a transaction replication system. See also primary database ,
primary transaction , replicate database , and transaction replication .
•
replicate site – the location or facility at which replicate data servers and replicate
databases are deployed to support normal business operations during scheduled downtime
at the primary site. Contrast with primary site . See also replicate database .
•
Replication Agent – an application that reads a primary database transaction log to
acquire information about data-changing transactions in the primary database, processes
the log information, and then sends it to a Replication Server for distribution to a replicate
database. See also
primary database and Replication Server .
•
replication definition – a description of a table or stored procedure in a primary database,
for which subscriptions can be created. The replication definition, maintained by
Replication Server, includes information about the columns to be replicated and the
location of the primary table or stored procedure. See also Replication Server and
subscription .
•
Replication Server – a Sybase software product that provides the infrastructure for a
transaction replication system. See also Replication Agent .
•
replication system – a data processing system that replicates data from one location to
another. Data can be replicated between separate systems at a single site, or from one or
more local systems to one or more remote systems. See also transaction replication .
•
rollback – an instruction to a database to back out of the changes requested in a unit of
work (called a transaction). Contrast with commit . See also transaction .
•
route – A one-way message stream from a primary Replication Server to a replicate
Replication Server. Routes carry data-changing commands (including those for RSSDs)
and replicated functions (database procedures) between separate Replication Servers. See
also
Replication Server .
•
RSSD – an abbreviation for Replication Server System Database, which manages
replication system information for a Replication Server. See also Replication Server .
•
SQL – an abbreviation for Structured Query Language, a nonprocedural programming
language used to process data in a relational database. ANSI SQL is an industry standard.
See also transaction .
•
stable queue – a disk device-based, store-and-forward queue managed by Replication
Server. Messages written into the stable queue remain there until they can be delivered to
the appropriate process or replicate database. Replication Server provides a stable queue
for both incoming messages (the inbound queue) and outgoing messages (the outbound
queue). See also database connection , Replication Server , and route .
•
stored procedure – a data server object that represents an operation or set of operations.
This term is often used interchangeably with
function .
•
subscription – a request for Replication Server to maintain a replicated copy of a table, or
a set of rows from a table, in a replicate database at a specified location. See also replicate
database , replication definition , and Replication Server .
