Data locking requirements
Two types of locking on the source content can be required during the
export process:
- Type 1: the suspension of changes
to the doc classes and CVLs
- Type 2: the suspension of all
changes to the source database (for example, making the source read-only)
The primary intent for this tool is not to make an exact copy of a CS
system to a Content Engine system. However, if you need the two systems
to be identical at the end of the export (with respect to documents and
versions) then certain considerations will apply:
-
The export must run during a time when there are no
other client modifications to the CS system (see Type 2 locking). If this can be accomplished for the duration of the export,
then a one-pass export is possible.
-
If Type 2 locking is not possible for the entire duration,
then a two-pass export must be used. A two-pass export requires Type
1 locking during the first pass and Type 2 for the second.
