Release 10.1B: Progress Fathom Replication
User Guide


Database connection considerations

As Fathom Replication is started, all database connections are disallowed until Fathom Replication startup and initialization phases are complete, unless you use the defer-agent-startup property in the server properties file. Disallowing database connections has different results based upon the type of client connecting. Client connections in this section are defined to be user sessions or utilities that perform actions on the database.

Table 3–1 shows the results of connecting during startup and initialization based on the type of client connecting.
