DSN_PROFILE_ATTRIBUTES_HISTORY profile table
The profile attributes history table, DSN_PROFILE_ATTRIBUTES_HISTORY, contains the attributes that were in effect at some point in time. The schema is SYSIBM.
The profile attributes history table, SYSIBM.DSN_PROFILE_ATTRIBUTES_HISTORY, contains the attributes that were in effect at some point in time. These attributes are defined in the profile attributes table, SYSIBM.DSN_PROFILE_ATTRIBUTES.
However, the ATTRIBUTE_TIMESTAMP column contains the timestamp of the associated PROFILEID in the profile history table. This table is used by optimization tools when diagnosing optimization problems.
The profile tables and related indexes are created when you run job DSNTIJSG during Db2 installation, as described in Job DSNTIJSG.
Do not manually insert data into this table. It is populated by START PROFILE command processing. Use care to delete rows only when they are no longer needed, for deliberate table maintenance.
The columns for SYSIBM.DSN_PROFILE_ATTRIBUTES_HISTORY are the same as the columns in SYSIBM.DSN_PROFILE_ATTRIBUTES. Except for the REMARKS column, which is named STATUS instead.
The value of the STATUS column indicates whether the profile was accepted, and when a profile was rejected contains information about the reason for the rejection.
Always check the status of any newly added profile table rows in the STATUS columns of DSN_PROFILE_HISTORY and DSN_PROFILE ATTRIBUTES_HISTORY tables after you issue the START PROFILE command. Successful completion of the START PROFILE command does not imply that all profiles started successfully. If the STATUS column of either history table contains a value that does not start with 'ACCEPTED', further action is required to enable the profile or the keyword action.
