可以使用以下命令显示 processPureQueryBindFiles 的完整语法:

print AdminTask.help('processPureQueryBindFiles')

清单 3 显示了上面描述的命令和输出。可以看到,在缺省情况下,将创建每个包的四个版本;数字 1 至 4 分别追加到每个包,以区分该包的隔离级别,每个数据库锁定隔离级别对应一个包。

清单 3. 使用命令行工具创建 DB2 包

C:\was70\bin>wsadmin -lang jython 
 
wsadmin>print AdminTask.listPureQueryBindFiles('[-appName JPA_EE_SAMPLE]') 
JPA_W_EJB.jar\META-INF\JPASample.pdqxml 
 
 
wsadmin>print AdminTask.help('processPureQueryBindFiles') 
WASX8006I: Detailed help for command: processPureQueryBindFiles 
 
Description: Process the pureQuery bind files that are in an installed application. Bind 
static SQL packages in a database. Refer to the information center documentation for the 
pureQuery bind utility. 
 
Target object:  None 
 
Arguments: 
 *appName - The name of an installed application that contains the pureQuery bind files 
to be processed. 
 classpath - A list of the paths to the .jar files that contain the pureQuery bind 
utility and its dependencies: pdq.jar, pdqmgmt.jar, and db2jcc4.jar or db2jcc.jar.  
Use / or \\ as a file separator. Use a blank space to separate the paths for the .jar 
files. 
 *url - The URL for connecting to the database. The format is jdbc:db2://server_name: 
port/database_name. 
 user - The user name for connecting to the database. 
 password - The password for connecting to the database. 
 options - Any additional options that are needed by the pureQuery bind utility.  
Provide bind options as: -bindoptions "options-string". Refer to the information center 
documentation for the pureQuery bind utility. 
 *files - A list of the names of the pureQuery bind files to be processed. The bind 
file path names must be relative to the application .ear file that contains them.  
Use / or \\ as a file separator. If you specify multiple file paths, use a blank space 
to separate them. 
 
Steps: 
 None 
 
wsadmin> wsadmin>print AdminTask.processPureQueryBindFiles('[-appName JPA_EE_SAMPLE 
 -classpath [C:\\pdq.jar C:\\pdqmgmt.jar C:\\db2jcc.jar ] -url jdbc:db2://localhost:50000 
/demodb -user db2admin 
 -password passw0rd -options [-bindoptions "BLOCKING NO"] -files [JPA_W_EJB.jar\\META-INF 
\\JPASample 
.pdqxml ]]')
