VSAM Edit Sharing Options panel
The VSAM Edit Sharing Options panel presents options which apply only when editing VSAM files that are potentially being shared by other users.
This is the case for the File Manager Base component when a KSDS SHAREOPTIONS 3 or SHAREOPTIONS 4 file is edited. It is also the case when a (non-KSDS) SHAREOPTIONS 3 or SHAREOPTIONS 4 file can not be allocated to the TSO session as DISP=OLD. Instead, the file is allocated DISP=SHR to allow access to the file and the edit continues with the restriction of inplace editing mode. Alternatively, this could be a CICS® file accessed through the File Manager CICS® product. In either of the above cases, these sharing options become active. These options are designed to provide improved useability for those files that are in such a shared environment.

- Autosave frequency
- For shared files, issue a AUTOSAVE command after a given number of changes. Set this value to 0 if you do not want an AUTOSAVE command to be issued.
- SAVE before starting
- When operating on a shared file, during a CHANGE command with
the ALL operand, this option determines if a SAVE is issued before
commencing the change.
Setting this ON ensures that any updates made to the file so far are saved. During the CHANGE ALL process, when using AUTORTRY (and a CHGASAVE value), the change process may need to refresh records as it goes (due to concurrent updates by other users). That refresh may discard other updates that had been made in this edit session to records on the file. To issue a SAVE before the CHANGE commences, and therefore ensure the state of the records that have been updated, leave the setting at ON.
- Change all autosave frequency
- This option applies specifically to the operation of the CHANGE command when used with the ALL parameter. Similar to the AUTOSAVE option above, it provides the ability to save records after a given number of changes. If used, the changes are counted at the record level. That is, if a record is changed (regardless of how many times the CHANGE command changed that record), it is counted as one change. When the number of records changed reaches the number set in this option, a SAVE command is issued and the CHANGE command continues.
- Auto retry for change all
- This option applies specifically to the operation of the CHANGE
command when used with the ALL parameter. This option controls the
action taken when a SAVE command is issued during operation of the
CHANGE command and another user has updated a record while the change
was running. If this option is set ON, the CHANGE command refreshes
(that is, it rereads) the record that this occurred on and attempts
to reapply the change.
If this option is OFF, each time File Manager detects that the record was updated before the CHANGE command saved the record, File Manager displays a popup window that gives you the choice of updating the record anyway, refreshing the record and reapplying the update, or aborting the CHANGE command.
