CHAInstance database schema

The CHAInstance table uses the following database schema for DB2® to store information about CHAInstance Entity EJBs:

Table 1. CHAInstance database schema
Column name Column type Max length Primary key? Usage
PARENTID VARCHAR 128 NO Used for CHA Instance EJB chaining function. This column is used to track the instance ID of the parent instance to which this CHA Instance is chained as a child.
INSTANCEID VARCHAR 128 YES Unique ID for this CHA Instance. These must be unique within the DB2 table and cannot be repeated.
NAME VARCHAR 80 NO The name of the Context being wrapped by the CHA instance. Used for By Name queries.
ISROOT SMALLINT 2 NO Indicator field populated if CHA Instance is the Root Context, null if not.
CONTEXT LONG VARCHAR (binary) or BLOB Unbound NO This is the physical Context instance wrapped by a given CHA Instance.
TYPENAME VARCHAR 80 NO Type name assigned to the Context. Used for By Type queries.
Note: CHAInstance CMP will only be called in CHA server side by CHASession Session Bean. So there is only local EJB interface for CHAInstance CMP.
