BI Presentation Services and BI Scheduler

Communication occurs between BI Presentation Services and BI Scheduler for BI Delivers. When a web user submits an iBot request, BI Presentation Services establishes communication with BI Scheduler. BI Presentation Services uses the username and password stored in its credential store under the alias of "admin" to connect to BI Scheduler. This username and password must match the BI Scheduler Administrator credential for successful authentication to occur.

The BI Scheduler Administrator account must be an account defined in the BI repository. This user must be assigned to the Administrator Group in the repository. This administrator account is required for two purposes:

• BI Scheduler uses its administrator credentials to run jobs on behalf of users that have submitted job requests. It uses the Oracle BI Server impersonation feature to impersonate users and submit the jobs on their behalf. To be able to use the impersonation feature, BI Scheduler must connect to BI Server as a repository administrator user.
• BI Presentation Services uses the credential to execute queries against the System subject area. This requires connecting as an repository administrator user. BI Presentation Services uses the credential stored under the alias "admin" in its credential store to make the connection.

The BI Scheduler Administrator account may be set to match the Oracle BI Administrator account. See the topic Synchronizing Oracle BI Administrator Password Changes.

Synchronizing BI Scheduler Administrator Account Changes

If you change the BI Scheduler Administrator username or password or both, you must synchronize this change with other components:

• Update the credential stored in the BI Presentation Services Credential Store under the alias admin. If you have multiple instances of BI Presentation Services in your Oracle BI deployment, then you must update the credential store for each BI Presentation Services instance to reflect this credential change.
• Ensure that a user with the new Scheduler Administrator username and password also exists in the repository and that this user has the Administrator group membership assigned to it. If you change the password for the BI Scheduler Administrator, you must change the password for that user in the repository to match the password reset.

NOTE:  For information on setting or changing the BI Scheduler Administrator account, see the chapter on configuring the BI Scheduler in the Oracle Business Intelligence Infrastructure Installation and Configuration Guide. This chapter also provides information on storing the BI Scheduler Administrator credentials in the BI Presentation Services Credential Store. For information on creating users in the BI repository and assigning Administrator group membership to users, refer to the Oracle Business Intelligence Server Administration Guide.
