db2联邦数据库

## 打开联邦数据库参数
  db2 update dbm cfg using FEDERATED YES

  db2 force application all
  db2stop
  db2start

2.编目数据库
    ##1.创建编目节点
    db2 connect to dwmm       #连接数据库
    db2 list node directory   #查看节点信息
    ##远程数据库全局设置
    db2set
    DB2COMM=TCPIP
    ##编目远程数据库节点[在本地数据库配置]
    ##node名称：NDBDPDB
    ##远程IP:192.168.0.16
    ##端口号：50000
    db2 "catalog tcpip node NDBDPDB remote 192.168.0.16 server 50000"
    db2 "terminate"
    ## 编目远程数据库
    db2 "catalog db bdpdb as DBBDPDB at node NDBDPDB authentication SERVER"
    db2 "terminate"
    ## 测试连接是否可用
    db2 "list db directory"
    db2 "connect to DBBDPDB user dw using password"
3.创建包容器
    db2 connect to dwmm
    db2 "CREATE WRAPPER DRDA"
    
4.创建连接对方数据的SERVER
  db2 "CREATE SERVER EDW TYPE DB2/UDB VERSION ‘9.7‘ WRAPPER DRDA AUTHORIZATION \"dw\" PASSWORD \"password\" OPTIONS (ADD NODE ‘NDBDPDB‘,DBNAME ‘DBBDPDB‘)"

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

6.创建联邦关系表
  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"
  ##查看联邦数据库是否可用
  db2 "get dbm cfg" | grep -i federated
  db2 "force applications all"
  db2stop
  db2start
    
    

##删除节点、编目数据库
    db2 uncatalog node nodename[节点名]
    db2 terminate
    db2 uncatalog db dbname[别名]
    db2 terminate

#删除表映射、用户映射、包容器、服务名
    DROP NICKNAME nickname     #删除表映射
    DROP SERVER server_name    #删除用户映射
    DROP WRAPPER wrapper_name  #删除包容器

1.检查并配置数据库参数
  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"
  ## 数据库参数,页大小4k,数据库日志
  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;

  ## 打开联邦数据库参数
  db2 update dbm cfg using FEDERATED YES

  db2 force application all
  db2stop
  db2start

2.检查并建立 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.检查并建立 TABLESPACE
  db2 -svtf crt_dwmm_spaces.ddl

  ### 数据表空间为 TS_DWMM TS_SYS_TMP
  ### 用户表空间 TS_USER_TMP
  ### 临时表空间 TEMPSPACE1
  ### 系统表空间 SYSCATSPACE SYSTOOLSPACE SYSTOOLSTMPSPACE
  db2 list tablespaces show detail|grep Name

4.创建数据库联邦
  ## 远程数据库全局设置
  db2set
  DB2COMM=TCPIP
  ## db2 get dbm cfg|grep -i TCP  --得到SVCENAME
  ## grep 上面的SVCENAME /etc/services

  ## 本地数据库设置
  ## 编目远程数据库节点
  db2 "catalog tcpip node NDBDPDB remote 155.101.252.172 server 50000"
  db2 "terminate"

  ## 编目远程数据库
  db2 "catalog db bdpdb as DBBDPDB at node NDBDPDB authentication SERVER"
  db2 "terminate"

  ## 测试连接是否可用
  db2 "list db directory"
  db2 "connect to DBBDPDB user dw using password"

  ## 创建数据库联邦
  db2 connect to dwmm user dainst using dainst;

  ## 创建WRAPPER
  db2 "CREATE WRAPPER DRDA"

  ## 创建连接对方数据的SERVER
  db2 "CREATE SERVER EDW TYPE DB2/UDB VERSION ‘9.7‘ WRAPPER DRDA AUTHORIZATION \"dw\" PASSWORD \"password\" OPTIONS (ADD NODE ‘NDBDPDB‘,DBNAME ‘DBBDPDB‘)"

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

  ## 创建联邦关系表
  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"

  ## 查看联邦数据库是否可用
  db2 "get dbm cfg" | grep -i federated
  db2 "force applications all"
  db2stop
  db2start

5.建ETL调度相关表
  db2 -svtf crt_dwmm_etl_table.ddl
