IBM UCD连接DB2时候碰到的问题
UCD 通过jdbc连接DB2的问题
1.No route to host.ERRORCODE=-4499, SQLSTATE=08001错误
防火墙问题,service iptables stop（测试环境，所以直接关闭）
2.数据库不是UTF-8
重新创建，并赋予连接id有dbadm权限
http://www.ibm.com/support/knowledgecenter/zh/SS4GSP_6.2.1/com.ibm.udeploy.install.doc/topics/dbinstall_db2.html
db2 grant dbadm on database to user XXXXX
3.db2jcc.jar包连接的话，需要更改为com.ibm.db2.jcc.DB2Jcc
提供 IBM UrbanCode Deploy 用来连接至数据库的 JDBC 驱动程序类。缺省值为 com.ibm.db2.jcc.DB2Driver。 [root@st ext]# ll total 3592 -rw——-. 1 root root 3670707 Jun 15 16:54 db2jcc.jar -rw——-. 1 root root 1015 Jun 15 16:54 db2jcc_license_cu.jar [root@st ext]#
另外测试jar包是否正确，从client段测试连接
[root@st ext]# /opt/ibm/java-x86_64-71/jre/bin/java -classpath /opt/ibm-ucd-6.2/server/lib/ext/db2jcc.jar com.ibm.db2.jcc.DB2Jcc -url jdbc:db2://XXXXXXXXXXst:50000/UCD -user ucdadmin -password xxxxxxxx
[jcc][10521][13706]Command : java com.ibm.db2.jcc.DB2Jcc -url jdbc:db2://XXXXXXXXXXst:50000/UCD -user ucdadmin -password ********
[jcc][10516][13709]Test Connection Successful.
DB product version = SQL10053
DB product name = DB2/LINUXX8664
DB URL = jdbc:db2://XXXXXXXXXXst:50000/UCD
DB Drivername = IBM DB2 JDBC Universal Driver Architecture
DB OS Name = Linux
[root@st ext]#
指定数据库所在server XXXXXXXXXXst
端口号 50000
连接id ucdadmin
连接id的密码 xxxxxxxx
classpath jar包所在的绝对路径
[DB2 JDBC Driver Versions and Downloads](http://www-01.ibm.com/support/docview.wss?uid=swg21363866）
Difference between IBM DB2 JDBC driver files - db2jcc.jar and db2jcc4.jar
Both of them are DB2 JDBC driver jar files and are Type 4 drivers.
db2jcc.jar includes functions in the JDBC 3.0 and earlier specifications. If you plan to use those functions, include the db2jcc.jar in the application CLASSPATH.
db2jcc4.jar includes functions in JDBC 4.0 and later, as well as JDBC 3.0 and earlier specifications. If you plan to use those functions, include the db2jcc4.jar in the application CLASSPATH.
Starting urbanCode Deploy server results in “java.lang.StackOverflowError”
