Question

简短说明：db_migrate IBM Db2 Warehouse客户端容器上的错误

我已经从docker成功安装了用于DB2 Warehouse的客户端容器v2.9.0。我正在尝试运行db_migrate命令，将数据从我们的“旧” PDA服务器复制到我们自己的DB2仓库。

docker run -itd --net=host -v db2wh_vol:/mnt/clientdir --name=client store/ibmcorp/db2wh_ce:v2.9.0-db2wh_client-linux

我正在客户端容器中发出以下命令（出于安全原因密码被隐藏）：

db_migrate -sdb BACC_DEV_STGPWRPT_SDFDM  -tdb BLUDB_24 -shost dstbld-pda02.bld.dst.ibm.com -suser h16720 -tuser bluadmin -spassword password -tpassword password  -sschema POTINA -tables "PO_FACT" "PRODUCT_DIMENSION" "CUSTOMER_DIMENSION"

开始加载作业，当我检查日志中是否存在引发错误的情况时：

您能帮我解决我做错了什么吗？预先感谢！

Answer 1

db_migrate仅支持从PDA（又名Netezza）到Db2 Warehouse的迁移。它不支持“普通”的Db2，既可以在内部使用，也不能在Cloud上作为Db2使用。即您的目标服务器是Db2 11.1.3.3，它不支持EXTERNAL TABLE。这就是为什么您收到An unexpected token "EXTERNAL"消息的原因。

即从Db2 Warehouse

touch /mnt/bludata0/scratch/test
db2 "INSERT INTO test SELECT * FROM EXTERNAL '/mnt/bludata0/scratch/test'"

SQL0100W  No row was found for FETCH, UPDATE or DELETE; or the result of a 
query is an empty table.  SQLSTATE=02000

但来自Db2

db2 "INSERT INTO test SELECT * FROM EXTERNAL '/tmp/test'"

DB21034E  The command was processed as an SQL statement because it was not a 
valid Command Line Processor command.  During SQL processing it returned:
SQL0104N  An unexpected token "EXTERNAL" was found following "FROM".  Expected 
tokens may include:  "<space>".  SQLSTATE=42601
