如何在linux环境下调试java程序使用访问timesten:-凯发app官方网站

上传jdk-6u7-linux-i586.bin文件到/data0/目录下，执行如下命令：
[root@ora11gr2 data0]#chmod 777 jdk-6u7-linux-i586.bin
[root@ora11gr2 data0]#./jdk-6u7-linux-i586.bin
[root@ora11gr2 data0]# ln -sn /data0/jdk1.6.0_07/ /usr/java 前面为源，后面为目的
[root@ora11gr2 data0]# vim /etc/profile
在文件最后，添加如下三行：
export java_home=/data0/jdk1.6.0_07
export classpath=.:$java_home/lib:$java_home/jre/lib
export path=/usr/java/bin:$path

[root@ora11gr2 data0]# source /etc/profile

timesten用户环境变量文件~/.bash_profile下添加如下几行：
[timesten@ora11gr2 ~]$ vim ~/.bash_profile
#add timsten env
export oracle_sid=mytest
export nls_lang=american_america.zhs16gbk
export oracle_home=/app/oracle/product/11.2.0/db_1
export tt_home=/data0/timesten/timesten/tt1122
export tns_admin=/app/oracle/product/11.2.0/db_1/network/admin
export classpath=/data0/timesten/timesten/tt1122/lib/ttjdbc5.jar:/app/oracle/product/11.2.0/db_1/jdbc/lib/ojdbc5.jar:$classpath
export path=/data0/timesten/timesten/tt1122/bin/:$oracle_home/bin:$path
export ld_library_path=$oracle_home/lib:/usr/lib:$oracle_home/network/lib:/data0/timesten/timesten/tt1122/lib:$ld_library_path

[timesten@ora11gr2 ~]$ javac
usage: javac
where possible options include:
-g                         generate all debugging info
-g:none                    generate no debugging info
-g:{lines,vars,source}     generate only some debugging info
-nowarn                    generate no warnings
-verbose                   output messages about what the compiler is doing
-deprecation               output source locations where deprecated apis are used
-classpath           specify where to find user class files and annotation processors
-cp                  specify where to find user class files and annotation processors
-sourcepath          specify where to find input source files
-bootclasspath       override location of bootstrap class files
-extdirs             override location of installed extensions
-endorseddirs        override location of endorsed standards path
-proc:{none,only}          control whether annotation processing and/or compilation is done.
-processor [,,...]names of the annotation processors to run; bypasses default discovery process
-processorpath       specify where to find annotation processors
-d              specify where to place generated class files
-s              specify where to place generated source files
-implicit:{none,class}     specify whether or not to generate class files for implicitly referenced files
-encoding        specify character encoding used by source files
-source           provide source compatibility with specified release
-target           generate class files for specific vm version
-version                   version information
-help                      print a synopsis of standard options
-akey[=value]              options to pass to annotation processors
-x                         print a synopsis of nonstandard options
-j                   pass directly to the runtime system

[timesten@ora11gr2 ~]$ javac -version
javac 1.6.0_07

2.编写java测试代码：

[timesten@ora11gr2 ~]$ cat tttest.java
import java.sql.*;
import javax.sql.*;
public class tttest{
public static void main(string args[])
{
//string url = "jdbc:timesten:client:dsn=lujgcs_1122"; remote connect strings
string url = "jdbc:timesten:direct:dsn=lujg_1122";

connection con = null;
try {
class.forname("com.timesten.jdbc.timestendriver");
}
catch (classnotfoundexception ex)
{ex.printstacktrace();
}
try {
con = drivermanager.getconnection(url);
system.out.println("connected");
java.sql.statement st=con.createstatement();
java.sql.resultset rs=st.executequery("select * from test");
while (rs.next())
{
system.out.println(rs.getstring("id"));
}

con.close();
} catch (sqlexception ex) {
ex.printstacktrace();}
}
}

编译程序：

[timesten@ora11gr2 ~]$ javac tttest.java
[timesten@ora11gr2 ~]$ ll
-rw-r--r-- 1 timesten oinstall 1395 mar 8 10:13 tttest.class
-rwxr-xr-x 1 timesten oinstall 715 mar 8 10:13 tttest.java

查看执行结果：

[timesten@ora11gr2 ~]$ java tttest
connected
100
200
300

这全是调试的过程么

环境变量的设置是个最基本的
