SharePlex 8.6.6 - Preinstallation Checklist

Routing specifications in a configuration file

The following instructions show you how to build a routing map. A routing map sends replicated data to the correct target on the correct target system.

Replicate to one target

A simple routing map sends replicated data from one source object to one target object.

src_owner.table tgt_owner.table2 host2[@database_specification]
src_owner.table tgt_owner.table3 host3[@database_specification]

Replicate to multiple targets

A compound routing map sends replicated data from one source object to multiple target objects. It enables you to specify the source and target objects once for all routes, rather than type a separate configuration entry for each route. Only one target specification can be used in a compound routing map, so all of the target objects must be identical as follows:

  • All one type: All the same database object type or all a JMS queue or all a JMS topic or all a Kafka topic, or all a file (but no combination of these).
  • All with the same fully qualified name, including any table specifications in a JMS, Kafka, or file target specification.
  • All having identical column or key mappings, if used (see Define a unique key and Map source and target columns).


  • Certain routing limitations apply when using vertically partitioned replication. See Configure vertically partitioned replication.
  • If any target has a different qualified name from the other targets of the same source object, you must use a simple routing map for that target.
src_owner.table tgt_owner.table


Replicate between objects on the same system

You can replicate between objects that are in the same database or in different databases on the same system. You can replicate between objects that have the same name, so long as their owners are different.

When SharePlex replicates between objects on the same system, it does not create Import and Export processes. You can force SharePlex to create Import and Export processes by using the following routing map. If you do not need the Import or Export processes, omit the host* portion of the routing map.

Routing Limitations

  • By default, SharePlex supports replication to a maximum of 19 direct target systems. That is the maximum number of processes that can read the export queue. To replicate to more than 19 targets, use named export queues. With each additional queue that you add, you can replicate to 19 additional targets. See Configure named export queues.
  • Each instance of sp_cop on a system permits a maximum of 1024 different routes. This limitation includes each route that uses a different named post queue (see Configure named post queues.) If your replication strategy requires more than 1024 routes, consider using one or more intermediary systems to divide the routes among multiple sp_cop instances. See Configure replication to share or distribute data).
  • By default, each sp_cop instance allows a total of 25 queues on a system. There will always be one capture queue on a source system and one post queue on a target. Therefore, you can have as many as 24 named export queues on a source system and 24 named post queues on a target system. If a system serves as both a source and target, you will have both a capture queue and a post queue. That allows you to create up to 23 named queues of either type (or a mix of both). If system memory permits, you can change the number of allowed queues by setting the SP_QUE_MAX_QUEUES parameter. See the SharePlex Reference Guide for more information about this parameter.
