Because of differences in the load and read structures for dynamic cluster tables,
the following standard features that are available in SAS tables and server tables
are currently not supported in
SPD Server 5.2:
-
You cannot directly append or update data in a
dynamic cluster table. To append a new member table to a dynamic cluster table, create the new member table
with the data to append. Then use the CLUSTER ADD statement to add the new member
to the table.
-
-
To refresh a dynamic cluster table by removing numerous old member tables and replacing
them with new member tables,
create the new member tables with the data to append. Then use the CLUSTER ADD and
CLUSTER REMOVE statements to first remove and then replace the old member tables
with new ones.
For more information,
see Example of Refreshing Dynamic Cluster Tables with CLUSTER REMOVE and CLUSTER ADD.
-
You can still use classic server PROC SPDO CLUSTER UNDO and CLUSTER CREATE statements
to refresh the member tables in a dynamic cluster table by unbinding the dynamic cluster
table and then re-binding it using new member tables.
This process temporarily makes the cluster table unavailable to other users, unlike
the process used by the CLUSTER REPLACE and CLUSTER REMOVE / ADD statements.
-
Record-level locking is not allowed.
-
The server backup and restore utilities
are not available.
If a task for a dynamic cluster table requires one of these features, you should uncluster
the dynamic cluster table and
create standard server tables.
