system as well as on the primary system. These other NonStop SQL DDL operations
include:
User programs cannot create audited NonStop SQL tables and write to them without
coordinating table creation on the primary system with table creation on the backup
system.
Recommended procedures for performing NonStop SQL DDL operations in an RDF
environment are described under NonStop SQL Databases in Section 6.
Enscribe File-Label Modifications
In general, RDF does not replicate Enscribe file-label modifications.
File-label modifications in Enscribe are similar to DDL operations in NonStop SQL in
that the modifications do not manipulate the file itself. Instead, file-label modifications
alter attributes of the file, such as the file code, the security, the extent size, and the
audit setting.
The only file-label modifications that RDF replicates are the following:
Purge Operations
The two kinds of purge operations are PURGEDATA and PURGE. RDF replicates
PURGEDATA operations for both SQL tables and Enscribe files. It replicates PURGE
operations for Enscribe files if REPLICATEPURGE is set on.
ALTER CATALOG ALTER VIEW RENAME CREATE INDEX
ALTER INDEX CREATE CATALOG CREATE TABLE
ALTER TABLE CREATE CONSTRAINT CREATE VIEW
DROP CATALOG DROP INDEX DROP VIEW
DROP CONSTRAINT DROP TABLE UPDATE STATISTICS
CREATE To create an audited Enscribe file
ALTER MAXEXTENTS To increase the number of extents for an audited
Enscribe file
PURGEDATA To purge data from an audited Enscribe file
PURGE To purge an Enscribe file (if REPLICATEPURGE is
enabled)
