"can not start a job" issue in AWM

Question

Hi ALL,
I am maintaining my cube from PLSQL with following options
1. buildtype = "BACKGROUND"
2. trackstatus = "true"
3. maxjobqueues = 3
i get following error when i see the "olapsys.xml_load_log" table
***Error Occured: Failed to Build(Refresh) DB_OWNER.MY_ANALYTICAL_WORKSPACE Analytic Workspace. Can not start a job.
Can anybody explain when and why this error occurs? I have wasted a lot of time searching for this issue, but have found no person facing such issue.
Hi Keith, it will be great if you can answer this one.
My database version is 10.2.0.4.0 and AWM version is also 10.2.0.3.0
Kind Regards,
QQ

Applies to:
Oracle OLAP - Version: 10.1 to 11.1
This problem can occur on any platform.
Symptoms
- We have an AW maintenance / refresh script or procedure that contains BuildType="BACKGROUND", so that the AW maintenance task will be sent to the Oracle Job queue.
- When we execute the AW maintenance / refresh script or procedure, we do not get any errors in the foreground, the script/procedure has been executed successfully.
- However when we look into the build/refresh log (see <Note 351688.1> for details) we see that the maintenance/refresh task failed with:
13:29:39 Failed to Submit a Job to Build(Refresh) Analytic Workspace <schema>.<AW Name>.
13:29:39 ***Error Occured in BUILD_DRIVER
- In the generated SQL trace for the session of the user who launches the AW build/refresh script or procedure, we see that ORA-27486 insufficient privileges error occurred at creation of the job.
We see from the relevant bit of the SQL trace that err=27486 occured while executing the #20 statement which is 'begin DBMS_SCHEDULER.CREATE_JOB ...', and the statement is parsed and tried to be executed as user having uid=91:
PARSING IN CURSOR #20 len=118 dep=2 uid=91 oct=47 lid=91 tim=1176987702199571

begin

'DEFAULT_JOB_CLASS', true, true, :3); end;
END OF STMT

1176987702325167
ERROR #20:err=27486 tim=465202984
Cause
User who tries to create a job (executes DBMS_SCHEDULER.CREATE_JOB() procedure) does not have the sufficient privileges.
Solution
1. Identify the user under which the job is supposed to be created. This user is not necessarily the same as the user who launched AW build/refresh script or procedure. Get the corresponding username from one of the %_USERS views e.g. from ALL_USERS.
e.g.
SELECT user_id,username FROM all_users WHERE user_id=91;
2. Identify the system privileges currently assigned to the user by connecting as the user whom the privileges need to be determined, and execute:
SELECT * FROM SESSION_PRIVS ORDER BY PRIVILEGE;
3. Ensure that the CREATE JOB privilege is listed.
The CREATE JOB privilege can be granted in various ways to a user:
- via role OLAP_USER or via role OLAP_DBA (see view ROLE_SYS_PRIVS for what privs are assigned to a role):
GRANT OLAP_USER TO <username>;
- explicitly
GRANT CREATE JOB TO <username>;
