create archive database

Description

Creates an archive database.

Syntax

create archive database db_name
	[on db_device [= size]
		[, db_device [= size] ] ... ] 
	with scratch_database = db_name

Parameters

on: specifies the modified pages section. Adaptive Server requires traditional database storage to store modified pages. Use the on clause to specify the location and size of the modified pages section.

db device: specifies the database device on which you want to create your modified pages section.

size: specifies the size of the modified pages section you want to create. If you omit size, 5120 pages are allocated.

with scratch_database: (required) specifies the name of an existing database in which information about the archive database is maintained. The sysaltusages system table, which maps logical pages in the archive database onto physical pages, is stored in the scratch database.

Examples

Example 1

The following syntax could be a typical archive database command sequence.

Create the scratch database if necessary, using the create database command.
```
create database scratchdb
    on datadev1 = 100
    log on logdev1 = 50
```
This creates a 150MB traditional database called scratchdb.
Use sp_dboption to designate the database you just created as a scratch database:
```
sp_dboption "scratchdb", "scratch database", "true"
```
Create the archive database.
```
create archive database archivedb
    on datadev2 = 20 
    with scratch_database = scratchdb
```
This creates an archive database called archivedb, with a 20MB modified pages section.

Materialize your archive database using load database:

load database archivedb
    from "/dev/dumps/050615/proddb_01.dmp"
    stripe on "/dev/dumps/050615/proddb_02.dmp"

Bring the database online:
```
online database archivedb
```
Check the consistency of the archive database using dbcc commands. For example:
```
dbcc checkdb(archivedb)
```

Load a transaction log dump using load tran and restore objects from the archive database using select into or bcp.

load tran archivedb
    from "/dev/dumps/050615/proddb1_log_01.dmp"
load tran archivedb
    from "/dev/dumps/050615/proddb1_log_02.dmp"
online database archivedb
select * into proddb.dbo.orders from     archivedb.dbo.orders
load tran archivedb
    from "/dev/dumps/050615/proddb1_log_03.dmp"
online database archivedb

Permissions

create archive database permission defaults to System Administrators, who can transfer it to users listed in the sysusers table of the master database. However, create archive database permission is often centralized to maintain control over database storage allocation.

create archive database permission is not included in the grant all command.
