KB20426: 'MSIRequest::CacheRequest(): Error executing cache request for project <XXXX> in schedule: HRESULT=0x0x80043018' error occurs in the DSSErrors.log file when MicroStrategy Intelligence Server scheduled jobs fail

SYMPTOM
Strategy Intelligence Server scheduled jobs fail with the following errors appearing in the DSSerrors log file:
 
2008-12-01 01:01:00.083-06:00 MSIRequest::CacheRequest(): Error executing cache request for project <XXXX> in schedule: HRESULT=0x0x80043018.
2008-12-01 01:01:00.099-06:00 MSIScheduler::ExecuteSimpleStmt(): Error executing DssCmdCacheAdmin schedule statement for : HRESULT=<-2147209192>.
CAUSE
The 0x80043018 and -2147209192 error codes mean that the project was in a Full Idle state (Request Idle + Execution Idle) at the time of the scheduled job execution. A Full Idle on a project cancels all currently executing or queued jobs and rejects any newly submitted jobs.
 
ACTION
There are two options to resolve this issue:
 

• Prevent the project from being placed in an Idle state
  

• Place the project in only Execution Idle; this way when the project is resumed later all of the jobs will be waiting in the queue
  

It is possible to achieve both of these actions through Strategy Developer or Strategy Command Manager. Which action and method of implementation to use will be completely dependent on the environment implementation.
