The converter is used to assign logical data pages to physical data pages. It is used simultaneously by all active users.
If any data pages that are not in the data cache need to be accessed, then a search is first made in the converter for their logical position. The corresponding physical position of the data pages in the data volumes is then determined.
Only the converter pages that contain a mapping of permanent data pages are written to the data volumes with each savepoint. In a restart, the pager can use these pages to restore the converter.
The converter is dimensioned dynamically, which means that you cannot set the size of the converter. The required converter pages are taken from the I/O buffer cache shared by the converter and the data cache.
