在.net安装程序中部署oracle客户端全攻略

主要的是要做三件工作: 打包文件,写注册表,注册环境变量
说明:我的oracle版本为9, 在2000 advanced server 上测试通过,可以正常创建数据库连接

1.打包文件
目录结果如下图所示

以下是我的打包程序中的文件目录,
bin : 最重要的当然是bin目录,在我的打包程序中,需要29个文件:

  --------------------
oci.dll
oraclient9.dll
oracommon9.dll
ORACORE9.DLL
orageneric9.dll
oraldapclnt9.dll
oran9.dll
ORANCDS9.DLL
orancrypt9.dll
oranhost9.dll
oranl9.dll
oranldap9.dll
ORANLS9.DLL
oranms.dll
oranmsp.dll
orannts9.dll
orannzsbb9.dll
oranoname9.dll
oranro9.dll
orantcp9.dll
orantns9.dll
ORAPLS9.DLL
ORASLAX9.DLL
ORASNLS9.DLL
ORASQL9.DLL
oratrace9.dll
ORAUNLS9.DLL
oravsn9.dll
orawtc9.dll
--------------------

networkadmin : tnsnames.ora
      tnsnames.ora文件内容如下:（SERVICE_NAME = 服务器的连接）
   ORCL =
      (DESCRIPTION =
        (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xxx.xxx)(PORT = 1521))
        )
        (CONNECT_DATA =
          (SERVICE_NAME = orcl)
        )
      )

ocommonnlsADMINDATA: 原oracle安装目录下所有文件
oracorezoneinfo : timezone.dat

2.写注册表
HKEY_LOCAL_MACHINESOFTWAREORACLE
"ORACLE_HOME" = "c:oracleora90"
我发现从网上查到的 HKEY_LOCAL_MACHINESOFTWAREORACLEHOME0下的ORACLE_HOME值并不是必须的.

3.注册环境变量
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlSession ManagerEnvironment
"path" += "D:oracleora90bin;"

这里需要注意的是最好不用把path直接设成这个值,这样会覆盖掉系统原有的path,所以最好是在原有的path上添加.但是.net安装程序中通过直接设置注册表无法做到,这时候可以通过添加自定义安装操作来在程序中完成.

一个问题是在设置path后不会立即生效,所以安装完程序后,系统找不到oracle的bin目录,无法建立数据库连接. 我现在的做法是把bin目录下的29个文件都拷贝到系统的[System目录](在.net的部署程序中,文件系统->特殊文件夹).有点恶毒阿,不过临时凑活着吧 :) 谁找到解决的办法记得告诉我阿

示例代码如下:

   
#region 检查Oracle客户端设置
        ///
        /// 检查Oracle客户端设置
        ///
        private void CheckOracleClient() {
            string[] keys = { "SYSTEM", "ControlSet001", "Control", "Session Manager", "Environment" };
            this.SetRegistryKey(Registry.LocalMachine, keys, "Path", @"c:oracleora90bin", true);
            keys = new string[] { "Software", "ORACLE"};
            this.SetRegistryKey(Registry.LocalMachine, keys, "ORACLE_HOME", @"C:oracleora90", false);
        }

        ///
        /// 将指定的值写入注册表
        ///
        /// <param name="startKey">初始的注册表项</param>
        /// <param name="registryKeys">注册表项数组，表示了指定值的路径</param>
        /// <param name="valueName">值的名称</param>
        /// <param name="value">要写入的值</param>
        /// <param name="append">是否在当前值前添加,若为否，则覆盖当前值</param>
        private void SetRegistryKey(RegistryKey startKey, string[] registryKeys, string valueName, string value, bool append) {
           
            RegistryKey rk = startKey;
            RegistryKey subKey = null;
            for (int i=0; i<registryKeys.GetLength(0); i++) {
                subKey = rk.OpenSubKey(registryKeys[i], true);
                if (subKey == null) {
                    subKey = rk.CreateSubKey(registryKeys[i]);
                }
                rk = subKey;
            }
          
            if (append) {
                if (rk.GetValue(valueName) == null) {
                    rk.SetValue(valueName, value);
                } else {
                    string oldValue = rk.GetValue(valueName).ToString();
                    if (oldValue.IndexOf(value) > 0) {
                        rk.SetValue(valueName, value + ";" + oldValue);
                    }
                }
            } else {
                if (rk.GetValue(valueName) == null) {
                    rk.SetValue(valueName, value);
                    rk.Flush();
                }
            }
            if (subKey != null) {
                subKey.Close();
            }
            rk.Flush();
            rk.Close();
        }
