Sybase跨平台dump/load 操作说明

ASE 12.5.3以上的版本可以进行跨平台dump/load
。

一．执行的
dbcc checkdb或任何其他dbcc命令来校验数据库运行干净

$ isql -Usa -P -SASE125

1>
dbcc checkdb("tec")

2> go

Checking tec: Logical pagesize is
2048 bytes

Checking sysobjects: Logical pagesize is 2048 bytes

The

total number of data pages in this table is 32.

Table has 336 data
rows.

……………………………………………………….

……………………………………………………….

Checking
tgh_jx: Logical pagesize is 2048 bytes

The total number of data pages
in this table is 1.

Table has 25 data rows.

Checking gy_con_area:
Logical pagesize is 2048 bytes

The total number of data pages in
this table is 1.

Table has 17 data rows.

Checking
gy_user_work_card_s1: Logical pagesize is 2048 bytes

The total number
of data pages in this table is 3.

Table has 106 data rows.

DBCC
execution completed. If DBCC printed error messages, contact a user with

System
Administrator (SA) role.

二．使用sp_dboption设置数据为单用户模式

1> use
master

2> go

1> sp_dboption tec,"single user",true

2>
go

Database
option 'single user' turned ON for database 'tec'.

Running
CHECKPOINT on database 'tec' for option 'single user' to take effect.

(return
status = 0)

三．使用sp_flushstats将内存中存储的统计信息刷新到systabstats系统表。你必须至少等
待10秒钟，等待进程完成

1> use tec

2> go

1> sp_flushstats

2>
go

DBCC execution completed. If DBCC printed error messages, contact
a user with

System Administrator (SA) role.

DBCC execution
completed. If DBCC printed error messages, contact a user with

System
Administrator (SA) role.

(return status = 0)

四．运行checkpoint命令
将所有脏页（自上次写入以来被更新的页）写入到数据库设备。你必须至少等待10秒钟，等待进程完成。

1> checkpoint

2>
go

五．运行卸载数据库。

1> use master

2> go

1> dump
database tec to "/data_backup/tec0912zm"

2> go

Backup Server: 4.58.1.1: Database tec:
36278 kilobytes DUMPED.

Backup Server: 4.58.1.1: Database tec: 57912
kilobytes DUMPED.

…………………………………………………………………………….

Backup Server:
4.58.1.1: Database tec: 585206 kilobytes DUMPED.

Backup Server:
4.58.1.1: Database tec: 586744 kilobytes DUMPED.

Backup Server:
3.43.1.1: Dump phase number 1 completed.

Backup Server: 3.43.1.1:
Dump phase number 2 completed.

Backup Server: 3.43.1.1: Dump phase
number 3 completed.

Backup Server: 4.58.1.1: Database tec: 586752
kilobytes DUMPED.

Backup Server: 3.42.1.1: DUMP is complete (database
tec).

六．取消sp_dboption单用户模式设置

1> sp_dboption tec,"single
user",false

2> go

Database option 'single user' turned OFF for
database 'tec'.

Running CHECKPOINT on database 'tec' for option
'single user' to take effect.

(return status = 0)

（必须在master
库 更改database options

You must be in the 'master' database in order
to change database options.）

七．将dump文件拷贝到windows
-ASE
服务器中

1.可使用ftp拷贝

2.也可以使用ftp工具
拷
贝

八．将windows-ASE服务器中建设备、建数据库

disk init name =
'webquery_data',

physname = 'c:/sybase/data/webquery_data.dat',

size =
'300M',

go

disk init name = 'webquery_log',

physname =
'c:/sybase/data/webquery_log.dat',

size = '90M',

go

九．建数据库

CREATE
DATABASE cpy_webquery

ON webquery_data = '300M'

LOG ON webquery_data = '90M'

go

十．Load数据库

load database
cpy_webquery from "d:/data_backup/webquery090317.dat"

十一.数据库联机

online
database cpy_webqeury

十二.重编译索引

Dump and Load a Database Across Platforms

Adaptive Server Enterprise
supports both the big endian and little endian platforms.

Overview

Adaptive
Server Enterprise, version 12.5.2, allowed the dump and load of
databases across platforms with the same endianness architecture.

With
Adaptive Server Enterprise, version 12.5.3, the dump and load databases
across platforms can now be done with different endianness
architecture. This means that a dump database and load database can be
done from a big endian platform to a little endian platform and from a
little endian platform to a big endian platform.

A big endian
platform is where the most significant byte is with the lowest address.
The little endian platform is where, within a given 16 or 32 bit word,
bytes at the lower addresses have a lower significance.

There is no
syntax change with dump or load database in version 12.5.3. Adaptive
Server automatically detects the endian of the database dump file at the
time of a load database, then performs the necessary conversions. Loads
in an older version, such as 11.9 and 12.0, are also supported. The
dump and load can be from 32 bit to 64 bit platforms, and vice versa.

Endian
platforms

Platforms supported:

Big endian Solaris
32/64 IBM

32/64 SGI 32/64 HPPA 64 HPIA 64 MAC 32

Little
endian Linux 1A 32 Linux 1A 64 NT Sun X86

Dump
and load across platforms with the same endian architecture

When
dump database and load database are done across platforms with the same
endian architecture, user and system data do not require conversions.
There are no limitations on operations with the dump and load of a
database. Adaptive Server Enterprise supports dump and load processes
for transactions and databases across platforms.

Dump and load across
platforms with different endian architecture

Dumping a database

Before
you run dump database, use the following procedures to move the
database to a transactional quiescent status:

1Verify the database
runs cleanly by executing dbcc checkdb or any other dbcc command.

2To
prevent concurrent updates from open transactions by other processes
during the dump database, place the database in a single user mode with
sp_dboption.

3Flush statistics to systabstats with sp_flushstats. You
must wait for at least ten seconds for the process to complete.

4Run
checkpoint against the database to flush updated pages. You must wait
for at least ten seconds for the process to complete.

5Run dump
database.

Loading a database

Once you load the database, Adaptive
Server automatically identifies the endian type on the dump file and
performs all necessary conversions during the load database and online
database.

Note When Adaptive Server converts the order for the index
rows some may be incorrect, you must recreate the indexes after loading
the database. See “sp_post_xpload” on page 27 for rebuilding indexes.

Restrictions

•Remote
dump transaction and load transaction to or from a back up server are
not supported.

•A password protected dump file cannot be loaded
across platforms.

•dump transaction and load transaction is not
allowed across platforms.

•If you dump database and load database for
a parsed XML object, you must parse the text again after the load
database is completed.

•You cannot perform the dump database and load
database across platforms on Adaptive Servers version earlier than
11.9.

•Embedded data structures stored as binary, varbinary, or image
columns are not done because Adaptive Server cannot translate these
structures.

•When you dump and load a master database, you must
recreate all logins in the syslogins because passwords are incompatible
between platforms.

•Reset the password using the command line
argument -psa on a master database after the load database is completed.
