Troubleshooting guide

•
Log Transfer Interface – an internal component of Replication Agent that interacts with
Replication Server to forward transactions for distribution to Replication Server. See also
Log Reader and Log Transfer Manager .
•
Log Transfer Language – the proprietary protocol used between Replication Agent and
Replication Server to replicate data from the primary database to Replication Server. See
also Log Reader and Log Transfer Interface .
•
Log Transfer Manager – an internal component of Replication Agent that interacts with
the other Replication Agent internal components to control and coordinate Replication
Agent operations. See also
Log Reader and Log Transfer Interface .
•
maintenance user – a special user login name in the replicate database that Replication
Server uses to apply replicated transactions to the database. See also replicate database and
Replication Server .
•
materialization – the process of copying the data from a primary database to a replicate
database, initializing the replicate database so that the replication system can begin
replicating transactions. See also atomic materialization , bulk materialization , and
nonatomic materialization .
•
Multi-Path Replication
™
– Replication Server feature that improves performance by
enabling parallel paths of data from the source database to the target database. These
multiple paths process data independently and are applicable when sets of data can be
processed in parallel without transactional consistency requirements between them.
•
nonatomic materialization – a materialization method that copies subscription data
without a lock on the primary database. Changes to primary data are allowed during data
transfer, which may cause temporary inconsistencies between the primary and replicate
databases. Contrast with atomic materialization . See also bulk materialization .
•
ODBC – an abbreviation for Open Database Connectivity, an industry-standard
communication protocol for clients connecting to data servers. See also
client , data server ,
and JDBC .
•
Open Client – a Sybase product that provides customer applications, third-party products,
and other Sybase products with the interfaces needed to communicate with Open Server
applications. See also Open Server .
•
Open Client application – An application that uses Sybase Open Client libraries to
implement Open Client communication protocols. See also Open Client and Open
Server .
•
Open Server – a Sybase product that provides the tools and interfaces required to create a
custom server. See also Open Client .
•
Open Server application – a server application that uses Sybase Open Server libraries to
implement Open Server communication protocols. See also
Open Client and Open
Server .
•
outbound queue – a stable queue managed by Replication Server to spool messages to a
replicate database. See also inbound queue , replicate database , and stable queue .
•
primary data – the data source used for replication. Primary data is stored and managed
by the primary database. See also primary database .
