Special considerations apply to the following cases in the IMS™ BMP or z/OS® batch environments:
- serial files implemented as GSAM (generalized sequential access
method) files
- IMS message queues
In either of these cases, be aware of the following considerations:
- If you close a record associated with a VSAM or sequential file,
EGL issues an OS CLOSE for the file.
- If you close a serial record associated with a GSAM file and the
file is open due to an add or get next statement, EGL issues a CLSE
call to the GSAM database.
