Abstract

LIC IASP VARY ON results in slow system performance.

Error Description

The count of iasp pages is kept in each main storage subpool.  
During normal system operations these counts can become        
corrupted.  If the counts go negative, the system will prevent  
any additional iasp pages from being used, causing performance  
problems.                                                      

Problem Summary

The count of iasp pages is kept in each main storage subpool.  
During normal system operations these counts can become        
corrupted.  If the counts go negative, the system will prevent  
any additional iasp pages from being used, causing performance  
problems.                                                      

Problem Conclusion

The code is changed such the the counts are now always accurate.
