ARCHIVE supports the saving of UDS databases even when they are open. This function is only intended for UDS databases, since it would result in an inconsistent file status if used for saving normal files.
The online saving of UDS databases is possible as of UDS-SQL V1.2 and provided the user is working with an after-image file (for further conditions, see the appropriate manuals for UDS-SQL).
In general, any opened file can be saved online. This requires, however, that the OPNBACK attribute has been set to YES with the CATAL(I) program interface and that ARCHIVE is running in OLS=YES mode. ARCHIVE does not guarantee the consistency of a file saved in this way.
The online saving of files is controlled via the OLS operand of the PARAM statement.
