标签: ojdbc

我正在使用Eclipse Luna并正在开发maven项目.当我在pom.xml中添加ojdbc jar的条目时,它在xml中给出了错误.由于groupId,artifactId和version都是正确的,我找不到任何问题的原因.

我该如何解决这个问题？

我正在尝试开发一个Oracle从eb服务类连接到数据库的Java EE应用程序,但我遇到了一个

SQLException: No suitable driver found for jdbc:oracle:thin:@//localhost:1521/orcl

我有ojdbc6.jar类路径,我也在JBoss部署文件夹中验证了这一点.

我的申请EAR是由一个WAR.这有什么问题(根本原因)？请帮忙.

persistence.xml中的连接URL:

> "jdbc:oracle:thin:@//localhost:1521/orcl"

ojdbc6.jar是否适用于JDK 1.7和Oracle 12c？我应该使用ojdbc7.jar吗？

先感谢您.

我是Gradle项目的新手,我有一个问题.我在互联网上搜索但我找不到我需要的东西,或者我不知道如何搜索它.首先,我要告诉你我的情况.我有一个Gradle项目,我希望将来使用jenkins执行几个自动化测试,但现在我想尝试Eclipse.我在/ lib目录中有oracle jdbc驱动程序,这是我的build.gradle

    apply plugin: 'java'

// In this section you declare where to find the dependencies of your project
repositories {
    jcenter()
    //mavenCentral()
}

// In this section you declare the dependencies for your production and test code

我想在一个类中使用这个jdbc驱动程序,但我不知道如何使用它.当我尝试使用Maven时,我使用了这种方式"import oracle.jdbc.driver.OracleDriver;" 但我想这对Gradle项目无效.你能帮我吗？提前致谢

我们遇到的问题是文本以某种不同的方式编码,但保存在表格的单个列中.很长的故事.在MySQL上,我可以"从表中选择十六进制(str)",然后我看到字符串的字节与我设置它们完全相同.

在Oracle上,我有一个以土耳其字符İ开头的字符串,它是Unicode字符0x0130"带有上面点的拉丁文大写字母".这是我的Unicode 2.0版书的印刷版.在UTF-8中,该字符为0xc4b0.

我们需要支持非常旧的客户端应用程序.他们会在"windows-1254"中将此文本发送给我们.我们过去只是闭上眼睛,存放它,然后再将其交还.现在我们需要Unicode,或者被赋予Unicode.

所以我有:

SQL> select id, name from table where that thing;

ID     NAME
------ ------------------------
746    Ý

这是有道理的,因为"İ"在Windows-1254中是0xdd而wondows-1252中的0xdd是"Ý".我的终端大概设置为通常的windows-1252.

但:

SQL> select id, rawtohex(name) from table where that thing;

ID     RAWTOHEX(NAME)
------ ------------------------
746    C39D

似乎没有相当于MySQL中的hex(name)函数.但我必须遗漏一些东西.我在这里错过了什么？

我的java代码必须使用我提供的utf8并保存utf8副本和windows-1252副本.java代码给了我:

bytes (utf8):  c4 b0
bytes (1254):  dd

然而,当我保存它时,客户端没有得到正确的字符.当我试图查看Oracle实际存储的内容时,我会看到上面看到的垃圾.我不知道C39D的来源.有什么建议？

我们在所有应用程序中都内置了ojdbc14.jar,并且我们正在连接到一个数据库,该数据库表示它是"Oracle Database 11g企业版版本11.2.0.2.0 - 64位生产".

我一直在尝试从Oracle OCI驱动程序切换到瘦驱动程序,我tnsnames.ora通过添加-Doracle.net.tns_admin=/path到命令行获得了瘦驱动程序来拾取我的驱动程序.

但是,我们tnsnames.ora包含一次定义多个服务的行.它们看起来像这样:

NEWS2,NEWS,NEWSFX = (DESCRIPTION_LIST=...)

OCI驱动程序似乎对这种格式感到满意,但瘦驱动程序并不了解那些是3个单独的服务NEWS2,NEWS并且NEWSFX.一些痛苦的调试会话显示,它认为这是一个名为的单一服务NEWS2,NEWS,NEWSFX.

可以理解,我们的DBA不太热衷于左右复制粘贴服务描述符,并且坚持认为我们找到了一种方法,可以在从OCI切换到精简之前为没有复制粘贴的同一服务描述符声明不同的名称.

使用oracle瘦驱动程序是否有正确支持的方法来实现这一目标？

PS:这是一个使用相同功能的人的帖子,并且还提到它显然没有文档:https://dbamarco.wordpress.com/2015/12/02/tnsnames-ora-secrets/

我刚刚完成了将我的oracle jar安装到glassfish库并ping使用正确的属性值成功连接和JDBC Pool到我的数据库.然后我选择它作为我的JDBC资源,之后我再次ping池,错误就是java.lang.RuntimeException在白色屏幕上打印这个类.

我需要设置一些特定的Oracle JDBC连接属性,以加快批处理INSERTs(defaultBatchValue)和质量SELECTs(defaultRowPrefetch).我得到了如何用DBCP实现这一目标的建议(感谢M. Deinum),但我想:

• 保留默认的Tomcat jdbc连接池
• 保留application.yml进行配置

我正在考虑spring.datasource.custom_connection_properties将来支持或类似的功能请求,并且由于这种尝试,这已经成为可能.我这样做是通过在创建DataSource时传递相关信息并操纵DataSource的创建,如下所示:

@Bean
public DataSource dataSource() {
    DataSource ds = null;

    try {
        Field props = DataSourceBuilder.class.getDeclaredField("properties");
        props.setAccessible(true);
        DataSourceBuilder builder = DataSourceBuilder.create();
        Map<String, String> properties = (Map<String, String>) props.get(builder);

        properties.put("defaultRowPrefetch", "1000");
        properties.put("defaultBatchValue", "1000");

        ds = builder.url( "jdbc:oracle:thin:@xyz:1521:abc" ).username( "ihave" ).password( "wonttell" ).build();

        properties = (Map<String, String>) props.get(builder);

        log.debug("properties after: {}", properties);
    } ... leaving out the catches ...
    }
    log.debug("We are using this …

在从Java 1.6升级到Java 1.8之前,我们能够登录Web应用程序.升级后,我们无法登录其中一个Web应用程序,但我可以登录到另一个.他们使用相同的Spring-Security,OJDBC和Hibernate版本.

但是,如果我们从类路径中删除了以下jar,只要您不需要使用钱包登录,登录就会再次起作用:

• com.oracle:oraclepki(12.1.0.2.0)
• com.oracle:osdt_cert(12.1.0.2.0)
• com.oracle:osdt_core(12.1.0.2.0)

在上层环境中删除它们不是一种选择,因为我们使用oracle钱包登录.

版本:

• OJDBC6 12.1.0.2.0
• SPRINGFRAMEWORK 3.0.7.RELEASE

调试日志

当我将日志级别设置为DEBUG时,我看到登录被拒绝作为anonomys用户,但在loggs之前它成功验证了登录名/密码.
