Unformatted event table column definitions

An unformatted event table is created when you issue a CREATE EVENT MONITOR statement that includes the clause WRITE TO UNFORMATTED EVENT TABLE. The column definitions are useful when you want to extract data to analyze or prune a table of unneeded data.

The column definitions for the unformatted event table are useful when you want to extract data from an unformatted event table using one of the following routines:
  • EVMON_FORMAT_UE_TO_XML - extracts data from an unformatted event table into an XML document.
  • EVMON_FORMAT_UE_TO_TABLES - extracts data from an unformatted event table into a set of relational tables.
The call to these routines accepts a SELECT statement that specifies the rows that you want to extract. Use the unformatted event table column definitions to assist with composing your SELECT statement.

There is no automatic purging of the event data written to an unformatted event table. You must manually purge data from the table. The column definitions for the unformatted event table are useful when you want to purge a targeted set of records. Another option is to remove all the table rows using the TRUNCATE TABLE statement.

As part of the CREATE EVENT MONITOR statement, you can specify what to name the associated unformatted event table. If not specified, the name defaults to the same name as the event monitor. The SYSCAT.EVENTTABLES catalog view lists event monitors, their associated unformatted table, and other details.

The following table describes the columns in the unformatted event table. The key column is the event_data column. The other columns represent identifiers that you can use to locate events of interest. For further attributes of table columns, issue a DESCRIBE statement.
