DB002300 C-4M353: DBIO Error:3005 against an IDMS VSAM file.
Release: All supported releases.
Sometimes the 3005 can be due to the fact that the file is not pointing to a buffer that is large enough to hold it. For VSAM, the file needs a buffer page size that is at least the size of the control interval. The buffer size must be able to fit the CI size, since that is what is read into the buffer. The control interval must be at least 8 bytes larger than the database page.
