Configuring Persistent Sessions

NSJSP 6.0 supports persistent sessions through the <Manager> element in the

context configuration file. Nest the <Manager> element below a <Context> element,

because the <Manager> element represents a session manager that can be used to

create and maintain session data for a particular web application.

If a <Manager> element is not specified for a <Context> element, a default

<Manager> configuration is automatically created that handles and stores session

data only for the life of the Container/JVM process. The default configuration uses the

com.tandem.servlet.catalina.session.NSJSPStandardManager class for

the className attribute in the <Manager> element. For more information on

NSJSPStandardManager, see context.xml on page 3-13.

Creating a NonStop SQL Database to store Persistent Session

Data

To successfully configure NSJSP for persistent sessions support, create a NonStop

SQL database (catalog and table) to store and save the persistent session data. The

following SQL scripts are used to create the persistent session:



nsjsp_createSessionStore_mp.sql (for SQL/MP)



nsjsp_createSessionStore_mx.sql (for SQL/MX)

To create the NonStop SQL database for storing the persistent session data, perform

one of the following tasks:



For NonStop SQL/MP database:

Copy the file nsjsp_createSessionStore_mp.sql and replace all

occurrences of =TheT1222SessionCatalog with the Guardian location (of the

form $Volume.SubVolume) where you want the persistent session catalog and

table to be created. This subvolume (disk) should be a TMF-audited data volume.

Use the following OSS command to forward the input file to the NonStop SQL

Command Interpreter (SQLCI):

osh> gtacl -p sqlci <

nsjsp_createSessionStore_mp.sql.your_copy



For NonStop SQL/MX database:

Copy the file nsjsp_createSessionStore_mx.sql and replace the

=TheT1222SessionCatalog string with a valid catalog name. Replace the

=TheT1222SessionSchema string with a valid schema name.

Note. The nsjsp_migrateSessionStore script migrates data from SQL/MP to

SQL/MX. For more information on this script, see nsjsp_migrateSessionStore on page 5-22.
