Not all the queries are cached all the time

Hi Guru's,

We are in BI7.

We have faced the following issues in caching the queries

1.Not all the queries are cached all the time

2.Some Folder Names are not generated; if the folder name is not generated then the caching is not used by the query (OSS Note 860013)

3.Some Time Caching is also not created

4.When the individual Reporting Agent jobs are run we don’t face this problem

5.No Roll-Out Memory is one of the issues that occurred frequently.

6.We have tested in D & T Systems

7.The Legacy query also have the same issue.

It's urgent.

Thanks in Advance.
