aix下讓sybase的所有庫(kù)從一個(gè)存儲(chǔ)遷移到另一個(gè)存儲(chǔ)，或者從一個(gè)vg遷移到另一個(gè)vg，抑或移動(dòng)sybase所有庫(kù)到新的位置，在aix下都可以通過(guò)拷貝相關(guān)lv實(shí)現(xiàn)。由于公司ibm小型機(jī)硬件原因，簡(jiǎn)單舉個(gè)遷移sybase設(shè)備從rootvg上到datavg的例子。過(guò)程如下：

成都創(chuàng)新互聯(lián)是一家集網(wǎng)站建設(shè),信豐企業(yè)網(wǎng)站建設(shè),信豐品牌網(wǎng)站建設(shè),網(wǎng)站定制,信豐網(wǎng)站建設(shè)報(bào)價(jià),網(wǎng)絡(luò)營(yíng)銷,網(wǎng)絡(luò)優(yōu)化,信豐網(wǎng)站推廣為一體的創(chuàng)新建站企業(yè)，幫助傳統(tǒng)企業(yè)提升企業(yè)形象加強(qiáng)企業(yè)競(jìng)爭(zhēng)力?？沙浞譂M足這一群體相比中小企業(yè)更為豐富、高端、多元的互聯(lián)網(wǎng)需求。同時(shí)我們時(shí)刻保持專業(yè)、時(shí)尚、前沿，時(shí)刻以成就客戶成長(zhǎng)自我，堅(jiān)持不斷學(xué)習(xí)、思考、沉淀、凈化自己，讓我們?yōu)楦嗟钠髽I(yè)打造出實(shí)用型網(wǎng)站。

一、基本信息

1 數(shù)據(jù)庫(kù)當(dāng)前的設(shè)備如下

name phyname

------------------------------ ------------------------

master /dev/rlv_master

sysprocsdev /dev/rlv_proc

2 rootvg的lv信息

# lsvg -l rootvg

rootvg:

LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT

hd5 boot 1 1 1 closed/syncd N/A

hd6 paging 64 64 1 open/syncd N/A

hd8 jfs2log 1 1 1 open/syncd N/A

hd4 jfs2 48 48 1 open/syncd /

hd2 jfs2 64 64 1 open/syncd /usr

hd9var jfs2 48 48 1 open/syncd /var

hd3 jfs2 48 48 1 open/syncd /tmp

hd1 jfs2 1 1 1 open/syncd /home

hd10opt jfs2 48 48 1 open/syncd /opt

lg_dumplv sysdump 16 16 1 open/syncd N/A

lv_master raw 5 5 1 open/syncd N/A

lv_proc raw 5 5 1 open/syncd N/A

lv_data1 raw 16 16 1 closed/syncd N/A

3 sybase RUN_CRM 文件內(nèi)容如下

$ cat RUN_CRM

#!/bin/sh

#

# Adaptive Server name: CRM

# ASE page size (KB): 2k

# Master device path: /dev/rlv_master

# Error log path: /sybase/ASE-12_5/install/CRM.log

# Configuration file path: /sybase/ASE-12_5/CRM.cfg

# Directory for shared memory files: /sybase/ASE-12_5

#

/sybase/ASE-12_5/bin/dataserver \

-sCRM \

-d/dev/rlv_master \

-e/sybase/ASE-12_5/install/CRM.log \

-c/sybase/ASE-12_5/CRM.cfg \

-M/sybase/ASE-12_5 \

4 sybase的接口文件內(nèi)容如下：

# cat interfaces

CRM

master tcp ether 192.168.85.9 5000

query tcp ether 192.168.85.9 5000

CRM_back

master tcp ether 192.168.85.9 5001

query tcp ether 192.168.85.9 5001

二、拷貝sybase的所有相關(guān)lv、本例sybase只有l(wèi)v_master lv_proc兩個(gè)lv （注意由于是簡(jiǎn)單模擬實(shí)驗(yàn)，所以sybase就只有這么兩個(gè)lv）

1 拷貝過(guò)程如下：

cplv命令解釋如下：

-y 新的lv名字

-v 目標(biāo)卷組名字

# cplv -y newlv_master -v datavg lv_master

cplv: Logical volume lv_master successfully copied to newlv_master .

# cplv -y newlv_proc -v datavg lv_proc

cplv: Logical volume lv_proc successfully copied to newlv_proc .

2 拷貝lv后datavg 的lv信息如下：

# lsvg -l datavg

datavg:

LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT

lv_backup jfs2 320 320 1 open/syncd /backup

loglv00 jfs2log 1 1 1 open/syncd N/A

newlv_master raw 10 10 1 closed/syncd N/A

newlv_proc raw 10 10 1 closed/syncd N/A

三、更改lv名字

1 更改原rootvg上sybaselv的名字

chlv命令參數(shù)解釋如下：

-n 為新lv名字

# chlv -n oldlv_master lv_master

# chlv -n oldlv_proc lv_proc

2 更改datavg上lv名字（由newlv_master--> lv_master| newlv_proc-->lv_proc)

# chlv -n lv_master newlv_master

# chlv -n lv_proc newlv_proc

四、啟動(dòng)服務(wù)后測(cè)試情況如下

1 啟動(dòng)主服務(wù)和備份服務(wù)

$ startserver -f RUN_CRM

$ startserver -f RUN_CRM_back

2 驗(yàn)證

如下可看到sybase主備服務(wù)已經(jīng)啟動(dòng)成功

$ showserver

USER PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND

sybase 319558 2.0 2.0 25564 17188 pts/1 A 11:42:25 0:03 /sybase/ASE-12_5/bin/dataserver -sCRM -d/dev/rlv_master -e/sybase/ASE-12_5/install/CRM.log -c/sybase/ASE-12_5/CRM.cfg -M/sybase/ASE-12_5

sybase 286878 0.0 1.0 7016 7440 pts/1 A 11:43:14 0:00 /sybase/ASE-12_5/bin/backupserver -SCRM_back -e/sybase/ASE-12_5/install/CRM_back.log -Ldefault -Jcp850 -N25 -C20 -M/sybase/ASE-12_5/bin/sybmultbuf

驗(yàn)證下master庫(kù)能否備份，如下：

$ isql -Usa -P -SCRM

1> dump database master to '/backup/master2.dat'

2> go

WARNING: In order to LOAD the master database, the SQL Server must run in

single-user mode. If the master database dump uses multiple volumes, you must

execute sp_volchanged on another SQL Server at LOAD time in order to signal

volume changes.

'sp_volchanged' system stored procedure after fulfilling any volume change

request from the Backup Server.
