Hello list, I have a couple questions about VSAM KSDS and splits. For example, if I create a KSDS with FSPC(0 0) and load it, there is no free space in it. I then come along and try to insert a record somewhere in the middle of a CI. This will result in a CI split which will then result in a CA split. Does this sequence result in both a CI and CA split in the VSAM statistics? Assuming that this scenario results in an increment in both the CI and CA split counts, is there any way a VSAM dataset can incur a CA split without a corresponding CI split? I am looking at a test VSAM that was built with minimal free space (3 0) and then it had a batch job run against it, doing inserts, deletes and a minor amount of updates. Once the job ended I looked at the statistics and found this:
SPLITS-CI----------50319 SPLITS-CA----------50555 Variable length records, average length 380, max length 4500. CISZ 18432. Non spanned records. How can I have 200 more CA splits than CI splits?
