Configuring multiple node EBS APPS tier – Split EBS APPS tier services on different nodes
Figure 4 Split EBS APPS tier services on different nodes
SGeEBS Toolkit can be used in multi node APPS tier configuration. You can configure EBS APPS
tier as two different packages, where one package includes Batch processing services and another
package supports all OLTP transaction processes, which includes opmn, oc4j, and forms services.
Batch processing services of EBS APPS tier accesses the database very frequently so there might
be heavy network traffic for these transactions. To reduce the load on one node, EBS APPS tier
can be configured in multiple nodes, where Batch processing is configured on one node and OLTP
processes on the other node. Figure 4 (page 13) shows an example of this type of configuration.
Figure 4 (page 13) Shows SGeEBS APPS Tier package configuration on four nodes of a cluster.
In the example, Node1 is running ECMT EBS DB Tier package and Node2 is running Batch
processing services and Node3 is running all OLTP processing services. In this configuration, two
APPS packages named BS_APPSpackage and OLTP_APPS package has been created.
BS_APPSpackage is configured to start, stop, and monitor Batch processing services of the EBS
APPS tier. OLTP_APPSpackage is configured to start, stop and monitor the OLTP processes. The
Batch processing and OLTP services have their own APPL_TOP installed on the disk that are shared
between the nodes and are configured to run the SGeEBS APPS Tier package.
If there is a failure in the Batch processing services, BS_APPSpackage is configured to failover to
Node1 and similarly if there is any failure in OLTP process, OLTP_APPSpackage is configured to
failover to Node4.

1. Specifying configuration parameters for BS_APPS package
Attributes which are to be modified in bsappspkg.ascii specifically for this configuration is
shown here:
#
#"package_name" is the name that is used to identify the package.
# Package names must be unique within a cluster.
#
package_name BS_APPSpackage
#
# "package_description" specifies the application that the package runs.
#
package_description "APPS Tier BS Package"
#
# "package_type" is the type of package.
# The package_type attribute specifies the behavior for this package.
