Synopsis

The PUSH function pushes a queued transaction to a destination node.

FUNCTION DBMS_DEFER_SYS.PUSH(
   destination IN VARCHAR2,
   parallelism IN BINARY_INTEGER := 0,
   heap_size IN BINARY_INTEGER := 0,
   stop_on_error IN BOOLEAN := FALSE,

   RETURN BINARY_INTEGER;

Parameters

Parameter Name

Description

destination

Global name of the destination database.

parallelism

Degree of parallelism:

0 = serial (no parallelism)
1 = parallel propagation with one slave
n = parallel propagation with n slaves

heap_size

If > 0, maximum number of transactions to examine simultaneously for parallel scheduling computation.

If 0, compute this number based on parallelism parameter.

stop_on_error

If TRUE, then stop on the first error, even if not fatal.

write_trace

If TRUE, record result in a trace file.

startup_seconds

Maximum number of seconds to wait for the completion of a previous push to the same destination.

execution_seconds

Maximum number of seconds to spend on the push before shutting down; defaults to seconds_infinity (i.e., unlimited).

delay_seconds

Shut down push cleanly if queue is empty for this many seconds.

transaction_count

Maximum number of transactions to push per execution.

delivery_order_limit

delivery_order ...
