First, develop a strategy for specifying multiple batches using the Object Where Clause parameter in the Batch Assignment component. Then, start multiple instances of batch assignment specifying the appropriate Object Where Clause for each instance. For example, you can run one instance of batch assignment for accounts that changed today and a different instance of batch assignment for accounts that changed yesterday. Use the Object Where Clause parameter to specify the following:
NOTE: These examples us a nonindexed field—LAST_UPD. It is recommended, however, that you use indexed fields for object WHERE clause statements. Also, use the appropriate database datetime functions to determine the current date and time depending on the database you are using. This example uses SYSDATE, which is specific to Oracle database datetime functions. To process mutually exclusive sets of records when running multiple instances of Assignment Manager simultaneously for the same assignment object, you should specify an Object Where Clause for each assignment task. You can also distribute the tasks on multiple Siebel Servers to enhance performance. When Not to Run Multiple, Simultaneous Batch JobsThere are several instances where you should not run multiple, simultaneous batch jobs:
Examples of when you should not run multiple simultaneous batch jobs include:
