Sybase databases

The following Sybase databases configuration settings should be considered prior to installing the CDC Replication Engine for Sybase databases:

Database partition changes
CDC Replication does not support database partition changes such as adding, removing, or moving except as documented for specific environments.
Setting the LANG environment variable (UNIX)
The UNIX Language environment variable [LANG] needs to be properly set for CDC Replication to open files with MBCS characters.
Database and backup restrictions
Before you can start replicating data from a Sybase database, you must follow certain database and backup restrictions on each database you want the CDC Replication Engine for Sybase databases to connect to.
Direct IO restrictions
The use of dsync and raw partitions is supported.
Compressed tables
The CDC Replication Engine for Sybase databases does not support compressed tables (tables that were created or altered by using the with/set compression = [page | row | all] clause).
Refresh performance considerations
The following considerations only apply if the Sybase database is used as a target of replication.
Enabling the creation of a partition table
The CDC Replication Engine for Sybase databases supports the creation of range partition tables.
