Question
What is a CI SPLIT ? What is a CA SPLIT?
Answers
- When the Control Interval does not have enough space, VSAM performs a split on CI by moving some of the records to the CIs that are free.
- In case of non-availability of free space, VSAM performs a control area split. This is done by new control area allocation and moving half of the CIs to it.

CI SPLIT:
- The movement of some records into another free CI in the same CA.
- CI Split needs certain number of Input / Output operations. This leads to degradation of VSAM file.
- The correct space is needed to allocate for CI.
- The result is half-empty CIs on contrary to one full and one empty CI.

CA SPLIT:
- CA Split is the process moving half of the records of one CA to a new CA.
- The addition or deletion of records can not accommodate in the existing CA.
- The result is two half-full CAs on contrary to one full and one empty CA.   Your Comment
