db2聯邦數據庫

目標機器：192.168.0.16
本地機器：192.168.0.18

1.登陸本地數據庫
db2 connect to dwmm user dainst using dainst

## 打開聯邦數據庫參數
  db2 update dbm cfg using FEDERATED YES

  db2 force application all
  db2stop
  db2start

2.編目數據庫
    ##1.創建編目節點
    db2 connect to dwmm       #連接數據庫
    db2 list node directory   #查看節點信息
    ##遠程數據庫全局設置
    db2set
    DB2COMM=TCPIP
    ##編目遠程數據庫節點[在本地數據庫配置]
    ##node名稱：NDBDPDB
    ##遠程IP:192.168.0.16
    ##端口號：50000
    db2 "catalog tcpip node NDBDPDB remote 192.168.0.16 server 50000"
    db2 "terminate"
    ## 編目遠程數據庫
    db2 "catalog db bdpdb as DBBDPDB at node NDBDPDB authentication SERVER"
    db2 "terminate"
    ## 測試連接是否可用
    db2 "list db directory"
    db2 "connect to DBBDPDB user dw using password"
3.創建包容器
    db2 connect to dwmm
    db2 "CREATE WRAPPER DRDA"
    
4.創建連接對方數據的SERVER
  db2 "CREATE SERVER EDW TYPE DB2/UDB VERSION '9.7' WRAPPER DRDA AUTHORIZATION \"dw\" PASSWORD \"password\" OPTIONS (ADD NODE 'NDBDPDB',DBNAME 'DBBDPDB')"

5.創建MAPPING
  db2 "CREATE USER MAPPING FOR dainst SERVER EDW OPTIONS (ADD REMOTE_AUTHID 'dw',REMOTE_PASSWORD 'password')"

6.創建聯邦關系表
  db2 "CREATE NICKNAME CORE.BGFMCINF FOR EDW.DW.F_CORE_BGFMCINF"
  db2 "ALTER NICKNAME CORE.BGFMCINF ALTER COLUMN ETL_FLAG LOCAL TYPE CHARACTER (1)"
  db2 "ALTER NICKNAME CORE.BGFMCINF ALLOW CACHING"
  ##查看聯邦數據庫是否可用
  db2 "get dbm cfg" | grep -i federated
  db2 "force applications all"
  db2stop
  db2start
    
    

 

##刪除節點、編目數據庫
    db2 uncatalog node nodename[節點名]
    db2 terminate
    db2 uncatalog db dbname[別名]
    db2 terminate

#刪除表映射、用戶映射、包容器、服務名
    DROP NICKNAME nickname     #刪除表映射
    DROP SERVER server_name    #刪除用戶映射
    DROP WRAPPER wrapper_name  #刪除包容器

 

1.檢查並配置數據庫參數
  db2 connect to dwmm user dainst using dainst;db2 set schema dainst;
  db2 RESET DATABASE CONFIGURATION FOR DWMM;
  db2 get db cfg|grep -wE "LOCKLIST|MAXLOCKS|LOGFILSIZ|LOGPRIMARY|LOGSECOND|SHEAPTHRES_SHR|SORTHEAP|UTIL_HEAP_SZ"
  ## 數據庫參數,頁大小4k,數據庫日志
  db2 UPDATE DATABASE CONFIGURATION FOR DWMM USING LOCKLIST 65536 MAXLOCKS 60 LOGFILSIZ 25600 LOGPRIMARY 15 LOGSECOND 30 SHEAPTHRES_SHR 250 SORTHEAP 8192 LOGBUFSZ 2048 UTIL_HEAP_SZ 65536;

  ## 打開聯邦數據庫參數
  db2 update dbm cfg using FEDERATED YES

  db2 force application all
  db2stop
  db2start

2.檢查並建立 BUFFERPOOL
  db2 connect to dwmm user dainst using dainst;db2 set schema dainst;
  db2 ALTER BUFFERPOOL IBMDEFAULTBP SIZE 250;
  db2 CREATE BUFFERPOOL BP32K SIZE 16384 PAGESIZE 32768;
  db2 CONNECT RESET;
  db2 connect to dwmm user dainst using dainst;db2 set schema dainst;
  db2 -x "select BPNAME,NPAGES,PAGESIZE from syscat.bufferpools with ur"

3.檢查並建立 TABLESPACE
  db2 -svtf crt_dwmm_spaces.ddl

  ### 數據表空間為 TS_DWMM TS_SYS_TMP
  ### 用戶表空間 TS_USER_TMP
  ### 臨時表空間 TEMPSPACE1
  ### 系統表空間 SYSCATSPACE SYSTOOLSPACE SYSTOOLSTMPSPACE
  db2 list tablespaces show detail|grep Name

4.創建數據庫聯邦
  ## 遠程數據庫全局設置
  db2set
  DB2COMM=TCPIP
  ## db2 get dbm cfg|grep -i TCP  --得到SVCENAME
  ## grep 上面的SVCENAME /etc/services

  ## 本地數據庫設置
  ## 編目遠程數據庫節點
  db2 "catalog tcpip node NDBDPDB remote 155.101.252.172 server 50000"
  db2 "terminate"

  ## 編目遠程數據庫
  db2 "catalog db bdpdb as DBBDPDB at node NDBDPDB authentication SERVER"
  db2 "terminate"

  ## 測試連接是否可用
  db2 "list db directory"
  db2 "connect to DBBDPDB user dw using password"

  ## 創建數據庫聯邦
  db2 connect to dwmm user dainst using dainst;

  ## 創建WRAPPER
  db2 "CREATE WRAPPER DRDA"

  ## 創建連接對方數據的SERVER
  db2 "CREATE SERVER EDW TYPE DB2/UDB VERSION '9.7' WRAPPER DRDA AUTHORIZATION \"dw\" PASSWORD \"password\" OPTIONS (ADD NODE 'NDBDPDB',DBNAME 'DBBDPDB')"

  ## 創建MAPPING
  db2 "CREATE USER MAPPING FOR dainst SERVER EDW OPTIONS (ADD REMOTE_AUTHID 'dw',REMOTE_PASSWORD 'password')"

  ## 創建聯邦關系表
  db2 "CREATE NICKNAME CORE.BGFMCINF FOR EDW.DW.F_CORE_BGFMCINF"
  db2 "ALTER NICKNAME CORE.BGFMCINF ALTER COLUMN ETL_FLAG LOCAL TYPE CHARACTER (1)"
  db2 "ALTER NICKNAME CORE.BGFMCINF ALLOW CACHING"

  ## 查看聯邦數據庫是否可用
  db2 "get dbm cfg" | grep -i federated
  db2 "force applications all"
  db2stop
  db2start

5.建ETL調度相關表
  db2 -svtf crt_dwmm_etl_table.ddl
