2.8 Exalogic Elastic Cloud Software
Oracle Exalogic Elastic Cloud Software includes a license-restricted set of features that enables improved performance and reliability of products within Oracle WebLogic
Suite. For information about using these optimizations on the Exalogic Elastic Cloud, see Enabling Exalogic-Specific Enhancements in Oracle WebLogic Server 11g Release
1 10.3.4 in Exalogic Elastic Cloud Enterprise Deployment Guide.
The following sections describe Oracle WebLogic Server configuration options that are restricted to Oracle Exalogic Elastic Cloud Software licenses:
■
Section 2.8.1, InputOutput and Work Manager Optimizations for Exalogic Elastic Cloud Software
■
Section 2.8.2, JDBC and Data Source Optimizations for Exalogic Elastic Cloud Software
■
Section 2.8.3, Cluster State Replication Optimizations for Exalogic Elastic Cloud Software

2.8.1 InputOutput and Work Manager Optimizations for Exalogic Elastic Cloud Software
Exalogic Elastic Cloud Software can be configured with inputoutput and Work Manager optimizations for WebLogic Server.
Table 2–1 lists and describes the MBean
attributes and WebLogic Server startup options for configuring WebLogic Server with these options that are restricted to Exalogic Elastic Cloud Software licenses.
2.8.2 JDBC and Data Source Optimizations for Exalogic Elastic Cloud Software
Exalogic Elastic Cloud Software can be configured with optimized JDBC connections and improved Oracle Database Real Application Cluster connectivity within WebLogic
Server. Table 2–2
lists and describes the Oracle JDBC features that are restricted to Exalogic Elastic Cloud Software licenses. Note, as stated in
Section 2.8.4, Socket Direct Protocol for Exalogic Elastic Cloud Software,
that WebLogic Server data sources using a JDBC connection string with the protocol portion being set to SDP
PROTOCOL=SDP are restricted to Exalogic Elastic Cloud Software.
