Configuring the Manager for Sessions Support
Note that the session_id field used above as the partitioning key contains only
hexadecimal characters (0 through 9 or A through F). As a result, per the above
examples:
•
All records with session IDs starting with 0 through 4 are stored in the main table.
•
All records with session IDs starting with 5 through 9 are stored in the partition
indicated by =TheFirstSessionPartition.
•
All records with session IDs starting with A through F are stored in the partition
indicated by =TheSecondSessionPartition.
Configuring the Manager for Sessions Support
To successfully configure NSJSP for persistent sessions support, create a <Manager>
element and nest it under a <Context> element in your
iTPWS_INSTALL_DIR/servlet_jsp/conf/iTP_server.xml configuration file, as
described. All implementations of the <Manager> element supports the following
attributes:
className
The Java class name of the implementation to use. This class must implement the
org.apache.catalina.Manager interface. If not specified, the default value
used is org.apache.catalina.session.NSJSPStandardManager.
distributable
If distributable is set to true, the session manager enforces the restrictions
described in the Servlet 2.3 specifications on distributable applications. Primarily,
this means that all the session attributes should implement the
java.io.Serializable interface. The default value is false.
The value of this property is automatically inherited from the web application
deployment descriptor (WEB-INF/web.xml) based on the presence or absence of
the <distributable> element.
Example 3-29. Adding Partitions Using the SQLCI ALTER TABLE Command
sqlci> alter table =TheT1222SessionCatalog.SessData add partition
=TheFirstSessionPartition.SessData FIRST KEY “5”
catalog =TheT1222SessionCatalog;
sqlci> alter table =TheT1222SessionCatalog.SessData add partition
=TheSecondSessionPartition.SessData FIRST KEY “A”
catalog =TheT1222SessionCatalog;
