一、Certification Details

Description

The "SAP Certified Development Associate - ABAP" certification exam verifies that the candidate has the fundamental knowledge required in the area of ABAP development. This certificate proves that the candidate not only has the pre-requisite understanding of ABAP development but is also able to apply these skills in a practical manner under the supervision of a project lead.

Notes

  • To ensure success, SAP recommends combining education courses and hands-on experience to prepare for your certification exam as questions will test your ability to apply the knowledge you have gained in training.
  • You are not allowed to use any reference materials during the certification test (no access to online documentation or to any SAP system).

    Topic Areas
    Please see below the list of topics that will be covered within this certification and the courses that cover them:

    General Information

    Exam Preparation

    Each specific certification comes with its own set of preparation tactics. We define them as "Topic Areas" and they can be found on each exam description. You can find the number of questions, the duration of the exam, what areas you will be tested on, and recommended course work and content you can reference. Please be aware that the professional- level certification also requires several years of practical on-the-job experience and addresses real-life scenarios.

    For more Information refer to our 5 simple steps of preparation for an exam and to ourFAQs.

    Safeguarding the Value of Certification

    SAP Education has worked hard together with the Certification & Enablement Influence Council to enhance the value of certification and improve the exams. An increasing number of customers and partners are now looking towards certification as a reliable benchmark to safeguard their investments. Unfortunately, the increased demand for certification has brought with it a growing number of people who to try and attain SAP certification through unfair means. This ongoing issue has prompted SAP Education to place a new focus on test security. Please take a look at our SCN blog to understand what you can do to help to protect the credibility of your certification status.

    Our Certification Test Security Guidelines will help you as test taker to understand the testing experience.

<think>好的,用户遇到了SAP服务器返回500 Internal Server Error的问题,需要帮助解决。首先,我需要回忆下常见的SAP服务器错误原因,以及如何排查这类问题。根据用户提到的rabax_state异常,这可能涉及到ABAP程序的运行时错误。 首先,我应该考虑常见的错误来源,比如ABAP代码中的异常未被捕获、数据库连接问题、配置错误或资源不足等。然后,按照步骤进行排查: 1. **检查日志**:SAP系统的系统日志(ST22)和应用日志(SM21)是首要的。ST22会记录ABAP运行时错误,而SM21会提供系统层面的详细信息。用户提到的rabax_state可能在ST22中有详细记录,需要查看具体的异常类型和位置。 2. **分析代码**:如果日志指向特定的ABAP程序或事务码,用户需要检查相关代码是否存在未处理的异常,比如使用TRY...CATCH块来捕获可能的错误。此外,检查是否有权限问题或数据库访问错误。 3. **系统资源**:检查服务器的内存、CPU使用情况,使用事务码ST06或OS级别命令。资源不足可能导致服务不可用,从而引发500错误。 4. **配置和补丁**:确认系统参数配置是否正确,比如RFC目标、HTTP服务设置。同时,查看是否有未应用的SAP Note或补丁,特别是与hdblcm相关的,参考提到的SAP Note 2078425可能会有帮助。 5. **网络和中间件**:检查网络连接是否正常,特别是如果涉及外部系统调用。中间件如SAP Gateway或ICF服务的状态也需要验证,使用事务码SICF检查服务是否激活。 接下来,生成相关问题时要覆盖用户可能进步想知道的内容,比如具体日志分析步骤、如何应用补丁、性能调优方法等。确保问题符合用户的技术背景,并提供有效的排查方向。 最后,确保回答结构清晰,步骤明确,引用相关的SAP Note,并指导用户如何逐步解决问题。同时,提醒用户如果自行排查困难,联系SAP支持的必要性。</think>### SAP服务器500 Internal Server Error(RABAX_STATE异常)的排查步骤 --- #### 1. **检查系统日志与应用日志** - **事务码 `ST22`(ABAP Dump分析)** 查看最近的ABAP运行时错误,定位引发`RABAX_STATE`异常的具体程序、事务码或函数模块。例如: $$ \text{RABAX\_STATE} \Rightarrow \text{未处理的异常或资源竞争} $$ [^1] - **事务码 `SM21`(系统日志)** 过滤时间戳,检查错误发生时是否存在数据库连接中断、内存溢出或锁表冲突(如`ENQ*`条目)。 --- #### 2. **验证ABAP代码与资源** - **代码异常处理** 检查相关ABAP程序是否缺少异常处理逻辑。例如: ```abap TRY. " 可能引发异常的代码 CATCH cx_sy_zerodivide INTO lx_exception. " 处理除零错误 ENDTRY. ``` - **资源限制** 使用事务码 `ST06` 或操作系统工具(如`top`、`free`)检查服务器内存、CPU使用率。若内存不足,调整SAP实例参数(如`phys_memsize`)。 --- #### 3. **检查配置与补丁** - **SAP Note应用** 参考SAP Note [2078425](https://launchpad.support.sap.com/#/notes/2078425) 排查生命周期管理工具(hdblcm)的潜在问题。 - **HTTP服务配置** 使用事务码 `SICF` 确认相关HTTP服务(如`/sap/public/bc/icf`)已激活且无配置错误。 --- #### 4. **数据库与网络排查** - **数据库连接** 检查事务码 `DB02` 的数据库状态,确认表空间、锁等待正常。 - **网络中间件** 验证防火墙规则、负载均衡配置,使用`telnet`或`curl`测试目标端口可达性。 --- #### 5. **测试与回滚** - **隔离测试** 在测试环境复现问题,逐步禁用自定义增强或第三方组件。 - **系统回滚** 若问题由最近变更(如传输请求、内核升级)引发,考虑回滚至稳定版本。 ---
