在windows上外部作业(包含远程外部作业)容易报以下错误:

Host Credentials报错"Connection to host as user oracle failed: ERROR: Wrong password for user"的解决一例


我成功安装了Oracle 10g,可以登录到企业管理器,但无法执行一些操作,如数据库的备份调度,
执行恢复等,由于操作系统登录全权证书的问题。我被要求提供操作系统登录凭证才可以执行这些操作。

我在Host Credentials那里输入的是用户administrator,并且administrator已经加入到了ORA_DBA组
但执行操作是报错如下:
Error: Connection to host as user oracle failed:
ERROR: Wrong password for user

如何解决这个问题呢?
我查阅了Oracle的官方文档,发现如下解决办法:

1. 打开组策略,用gpedit.msc命令。
2. 逐步找到compute configuration -- windows setting -- security setting -- local policy
-- user rights assignment -- log on as a batch job
3.双击"log on as a batch job",在这里加入你需要的操作系统user
4.再次在OEM的Host Credentials输入那些user和password,一切ok。

老师,执行外部job的时候有如下报错,但是我的操作系统,oracle账号,密码没写错,不知道什么情况了。
EXTERNAL_LOG_ID="job_74991_1846", ORA-27369: job of type EXECUTABLE failed with exit code: Argument list too long STANDARD_ERROR="Launching external job failed: Invalid username or password"

这些信息都确认过了:
Make sure $ORACLE_HOME/rdbms/admin/externaljob.ora is owned by root :
cd $ORACLE_HOME/rdbms/admin/
chown root externaljob.ora
Make sure the file permissions are correctly set :
chmod 640 externaljob.ora
make sure extjob is executable :
cd $ORACLE_HOME/bin
chmod 4750 extjob

以下是配置信息:
program2.sh
  1. #!/bin/sh
  2. date >> /home/oracle/program2.txt
复制代码
  1. chmod +x program2.sh
复制代码

  6. number_of_arguments=>0,
  7. comments=>'',
  8. enabled=>TRUE);
  9. END;

  6. schedule_name => '"TEST"."SCHEDULE2"');
  7. END;

  5. end;
复制代码

JOB:
  1. grant create external job to test;
  2. grant execute on credential2 to test;
复制代码
  1. BEGIN
  2. sys.dbms_scheduler.create_job(
  3. job_name => '"TEST"."JOB2"',
