DFS3386I OSAM CF CACHING RATIO = ddd:eeer
Explanation
A coupling facility structure was defined for OSAM. The values specified for ddd and eee represent the coupling facility directory-to-element ratio. The directory-to-element ratio is active for the issuing IMS. These values might be used to configure the OSAM structure. The ratio values active for the first IMS that connects to the coupling facility establishes the directory-to-element ratio. Other IMS regions connecting to the same structure will use the structure previously configured.
- 1
- The CFOSAM= keyword on the CFNAMES statement did not specify the directory-to-element ratio. IMS supplies a default ration of 999:1.
- 2
- The directory-to-element ratio was specified with the CFOSAM= keyword and is active.
- 3
- The directory-to-element ratio was specified with the CFOSAM= keyword, but defines an incorrect ratio and cannot be used. The result of dividing the element value by the directory value must not exceed the maximum number of 16 elements. The ratio IMS provided is used instead of the externally specified ratio.
- 4
- The element portion of the directory-to-element ratio as specified by the CFOSAM= keyword is zero. The resultant ratio becomes 1:0. This ratio causes the OSAM structure to be configured for directory-only processing. No data elements will be available for data caching.
System action
IMS initialization processing continues. The ratio specified is active for the issuing IMS.
Programmer response
No response is required unless the directory-to-element ratio used to configure the OSAM structure is not the ratio you want. In this case, specify or change the directory and element values on the CFNAMES statement and restart the IMS sysplex.
