Content Platform Engine, Version 5.2

Creating an object store

Object stores are used to store documents, workflows and other objects. The New Object Store wizard leads you through the steps required to create an object store.

Before you begin

When creating an object store, you either reuse an existing database connection or, if your object store must have its own database, you must follow the same procedures required for creating the initial object store. If you are reusing an existing database connection, you can run the New Object Store wizard without any further preparations.

When creating an object store you have these choices:

reuse an existing database connection. In this case you can run the New Object Store wizard, explained below, without further preparation.
put your object store into its own database. In this case you must first follow the database creation and preparation instructions explained in Database administrator installation tasks. Then run the database connection wizard, explained in Creating a database connection. Then run the New Object Store wizard, explained below. Use your new database connection while running the wizard.

Note: A single database and database connection can serve more than one object store. If you are using database sharing, you can use the database connection for more than one object store, provided you assign a unique schema name to each object store. However, if an object store must have its own database, you cannot reuse the database connection. Do these prerequisite steps once for each nonshared object store.

About this task

The New Object Store wizard fails to complete if you try to assign the new object store to a database connection and schema name that has already been used.

If you encounter timeout errors when you create an object store or when you subsequently import add-on features, the transaction timeout value setting might be too low. To modify the transaction timeout value, see the appropriate topic for your application server:

Procedure

To create an object store:

Start IBM® Administration Console for Content Platform Engine if you did not already do so:
1. On any computer, open a browser and navigate to the IBM Administration Console for Content Platform Engine logon page:
  - In a standard availability environment, the logon page is at http://CPE_Server:port/acce. CPE_Server is the name of the system where Content Platform Engine is deployed. port is the HTTP port that is used by the application server where Content Platform Engine is deployed.
  - In a high availability environment, the logon page is at http://virtual_server:port/acce. virtual_server is the name of the load balancer or proxy server where the clusters of Content Platform Engine is deployed. port is the port number of the load balancer or proxy server.
2. Log on as the gcd_admin user.
In the tree view, right-click the Object Stores container and choose New Object Store to start the wizard.
Complete the wizard screens by using the values in your worksheet.
Important: The maximum row size of the underlying DB2® database tables is 32 KB. Therefore, choose a minimal set of add-on features before creating an object store. After the object store exists, be aware that each user property reduces the row size from what already is reserved by the current system and add-on properties. You should initially allocate string properties to be as small as possible; you can increase the sizes later in IBM Administration Console for Content Platform Engine. A string property with a large allocation size is more space efficient if you create it as a long string data type; however, long strings have some functionality limitations.

What to do next

After an object store is created, you can define its document classes, folders, security policies, and other features required by your system design.

To enable content-based retrieval, see Finding objects with content-based retrieval.

Set up a file storage area or install a fixed content device, depending on where the object store will store content.
