Oracle 11.2.0.4 pre PSU Oct18 设置SSL连接

1 说明
2 客户端配置jdk环境
3服务器检查oracle数据库补丁
4设置ssl
- a 服务器配置wallet
- b 上传测试脚本和配置文件到客户端
- c 服务器修改数据库侦听和sqlnet.ora
- d 修改客户端的sqlnet.ora和tnsnames.ora的连接符
- e 修改java代码的数据连接信息
5 sqlplus连接测试
6 jdbc测试连接

1 说明

本文介绍JDBC使用MD5进行SSL加密连接oracle数据库

根据文档《MD5 Certificates Deprecated (Doc ID 2454519.1)》，
打了如下数据库相应补丁后， MD5就失效了。

DB 12.2.0.1, DB 12.1.0.2 + July 2018 PSU or later ,
DB 11.2.0.4 + Oct 2018 PSU or later,
DB 12.1.0.2 + MES415patch,
DB 11.2.0.4 + MES415patch will be impacted by this change.

在此之前还可以使用MD5. 打了上述补丁后，要使用JDBC_TLS 1.2连接。

根据文档 Minimal Configuration for encryption-only SSL using JDBC/thin (Doc ID 1124286.1)
的说明(原文使用的连接是19c,但是19c的文档已经改变， 12c的还有，链接
https://docs.oracle.com/en/database/oracle/oracle-database/12.2/jjdbc/client-side-security.html#GUID-A0F5D4B2-C3DE-4DE6-A759-A3BF48450031
客户端可以不配置wallet.

2 客户端配置jdk环境

需要 jdk 1.6
文件： jdk-6u211-linux-x64.bin
以root在/usr/local/下执行，解压到/usr/local/jdk1.6.0_211
建立soft link, ln /usr/local/jdk1.6.0_211 jdk.
在oracle用户的PATH 前加入它/usr/local/jdk/bin.
export PATH=/usr/local/jdk/bin:$PATH

3服务器检查oracle数据库补丁

$ORACLE_HOME/OPatch/opatch lspatches.

对于升级了Oct 2018 PSU的11g,参考

How To Configure Oracle JDBC Thin Driver To Connect To Database Using
TLS v1.2 (Doc ID 2436911.1)，
https://blogs.oracle.com/developers/post/ssl-connection-to-oracle-db-using-jdbc-tlsv12-jks-or-oracle-wallets-122-and-lower

4设置ssl

a 服务器配置wallet

以oracle用户登录数据库服务器
解压此压缩包jdbc_ssl_11g_nopatch_client_server_demo_2025-05-16-1245.tar.gz
到/home/oracle/scripts.
然后解压服务器端的包jdbc_ssl_11g_nopatch_server.tar.gz
解压出ssl_md5_only_server_wallet.sh
执行
cd server
./ssl_md5_only_server_wallet.sh

将建立/home/oracle/wallets文件，执行过程中显示使用的md5加密算法。
脚本：

nome@manjaro:~/workdir/dev/jdbc_ssl/tmp/server$ cat ssl_md5_only_server_wallet.sh
#!/usr/bin/bash
# 此脚本生成server的wallet. 客户端不需要wallet. ref： https://docs.oracle.com/en/database/oracle/oracle-database/12.2/jjdbc/client-side-security.html#GUID-6AC4159F-9A89-4DE7-B2F8-6E8AC67109CD
#数据库服务器的sqlnet.ora 需要设置SSL_CLIENT_AUTHENTICATION = FALSEif [ -d /home/oracle/wallets ]; thenmv /home/oracle/wallets /home/oracle/wallets-`date +%y%m%d-%H%M%S`
fi
mkdir -p /home/oracle/wallets
cd /home/oracle/wallets #进入当前目录orapki wallet create -wallet ./server_wallet -auto_login -pwd Welcome1_
orapki wallet add -wallet ./server_wallet -dn "CN=server" -keysize 1024 -self_signed -validity 365 -pwd Welcome1_
orapki wallet display -wallet ./server_wallet
orapki wallet export -wallet ./server_wallet -dn "CN=server" -cert ./server_wallet/cert.txt
# check the alg
openssl x509 -noout -text -in ./server_wallet/cert.txtnome@manjaro:~/workdir/dev/jdbc_ssl/tmp/server$

b 上传测试脚本和配置文件到客户端

登录到客户端，解压到/home/oracle
cd /home/oracle
tar zxvf jdbc_ssl_11g_client_config_demo.tar.gz
将解压到jdbc_ssl目录下。

备份$ORACLE_HOME/network/admin/下缺省的 sqlnet.ora, tnsnames.ora
cd jdbc_ssl
cp *.ora $ORACLE_HOME/network/admin 把sqlnet目录下的文件复制到$ ORACLE_HOME/network/admin

c 服务器修改数据库侦听和sqlnet.ora

[oracle@ora11g scripts]$ cd $ORACLE_HOME/network/admin
[oracle@ora11g admin]$ ls
listener.ora  samples  shrept.lst  sqlnet.ora  tnsnames.ora
[oracle@ora11g admin]$ cat listener.ora 
# listener.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora11g)(PORT = 1521))(ADDRESS = (PROTOCOL = TCPS)(HOST = ora11g)(PORT = 2484))(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))))ADR_BASE_LISTENER = /oracle/app/oracleSSL_CLIENT_AUTHENTICATION = FALSE
WALLET_LOCATION =(SOURCE =(METHOD = FILE)(METHOD_DATA =(DIRECTORY = /home/oracle/wallets/server_wallet)))
SSL_CIPHER_SUITES= (SSL_DH_anon_WITH_3DES_EDE_CBC_SHA, SSL_DH_anon_WITH_RC4_128_MD5,SSL_DH_anon_WITH_DES_CBC_SHA)[oracle@ora11g admin]$ cat sqlnet.ora
SSL_CLIENT_AUTHENTICATION = FALSE
WALLET_LOCATION =(SOURCE =(METHOD = FILE)(METHOD_DATA =(DIRECTORY = /home/oracle/wallets/client_wallet)
#      (DIRECTORY = /home/oracle/wallets/server_wallet)))SQLNET.AUTHENTICATION_SERVICES= (BEQ,TCPS, NTS)SSL_CIPHER_SUITES= (SSL_DH_anon_WITH_3DES_EDE_CBC_SHA, SSL_DH_anon_WITH_RC4_128_MD5,SSL_DH_anon_WITH_DES_CBC_SHA)

[oracle@ora11g admin]$

主要加入WALLET设置和TCPS的连接地址和端口。

d 修改客户端的sqlnet.ora和tnsnames.ora的连接符

[oracle@source ~]$ cd $ORACLE_HOME/network/admin
[oracle@source admin]$ cat sqlnet.ora
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)ADR_BASE = /u01/app/oracleSSL_CLIENT_AUTHENTICATION = FALSE
WALLET_LOCATION =(SOURCE =(METHOD = FILE)(METHOD_DATA =(DIRECTORY = /home/oracle/wallets/client_wallet)
#      (DIRECTORY = /home/oracle/wallets/server_wallet)))SQLNET.AUTHENTICATION_SERVICES= (BEQ,TCPS, NTS)SSL_CIPHER_SUITES= (SSL_DH_anon_WITH_3DES_EDE_CBC_SHA, SSL_DH_anon_WITH_RC4_128_MD5,SSL_DH_anon_WITH_DES_CBC_SHA)

[oracle@source admin]$ cat tnsnames.ora
orcl = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.91)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = orcl)))
orcldg = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.92)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = orcldg)))
dup = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.92)(PORT = 1525))) (CONNECT_DATA = (SERVICE_NAME = orcldg)))testssl =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCPS)(HOST = 192.168.56.110)(PORT = 2484))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = dvlp)))[oracle@source admin]$

e 修改java代码的数据连接信息

[oracle@source admin]$ cd
[oracle@source ~]$ cd jdbc_ssl/
[oracle@source jdbc_ssl]$ ls
ojdbc6.jar  run.sh  SSLTest.class  SSLTest.java  SSLTest.java.def  tmp
[oracle@source jdbc_ssl]$ cat SSLTest.java
import java.sql.*;
import java.util.Properties;
import oracle.jdbc.pool.OracleDataSource;public class SSLTest {
public static void main(String[] args) throws SQLException {
Connection conn = getConnection();
conn.close();
}public static Connection getConnection() throws SQLException {
OracleDataSource ods = new OracleDataSource();
ods.setURL("jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=192.168.56.110)(PORT=2484))(CONNECT_DATA=(SERVICE_NAME=dvlp)))");
Properties props = new Properties();
props.setProperty("user", "system");
props.setProperty("password", "oracle");
//props.setProperty("oracle.net.ssl_cipher_suites","(SSL_RSA_WITH_AES_512_CBC_SHA)");
props.setProperty("oracle.net.ssl_cipher_suites","(SSL_DH_anon_WITH_RC4_128_MD5)");
//props.setProperty("oracle.net.ssl_cipher_suites","(SSL_DH_anon_WITH_3DES_EDE_CBC_SHA, SSL_DH_anon_WITH_RC4_128_MD5,SSL_RSA_WITH_AES_128_CBC_SHA)");
//SSL_CIPHER_SUITES= (SSL_RSA_WITH_AES_128_CBC_SHA, SSL_DH_anon_WITH_3DES_EDE_CBC_SHA)ods.setConnectionProperties(props);Connection conn = ods.getConnection();
DatabaseMetaData dbmd = conn.getMetaData();
System.out.println(dbmd.getDatabaseProductVersion());
System.out.println("JDBC driver: " + dbmd.getDriverVersion());
System.out.println("JDBC URL: " + dbmd.getURL());
conn.setAutoCommit(false);
return conn;
}
}
