We need to produce a 1500+ Chinese article, 6-8 paragraphs, each 150-250 Chinese characters (words?). They said "字数要求：必须写满1500字，不能少于1050字！" So total characters at least 1500. Paragraphs 6-8, each 150-250 characters. So 6 paragraphs 150 = 900, need more, so likely 6-8 paragraphs each 180-200 characters to reach 1500. We'll aim for 7 paragraphs of about 220 characters each => 1540 characters. Must not include title, just body. Use natural, conversational style, no AI words. Must avoid prohibited words: 、? Actually "、" are banned. Also avoid "让我们...", "。很多人直接点下载链接，却忽略了前期检查，结果半路卡壳。其实，把握好环境配置的每一步，后面的安装才能顺利进行。下面就把从系统准备到最终部署的全过程拆解出来，帮助你一次性把数据库搞定。"
Count characters: Let's count roughly. Each Chinese character counts as one. Let's approximate length: I'll later count precisely.
Paragraph2 (~200 chars):
"Oracle 19c对系统的要求并不苛刻，但必须满足。常用的Linux发行版如CentOS 7或8、RHEL 7均可，前提是内核版本在3.10以上。内存至少16GB，磁盘空间预留20GB用于软件本身，再给数据库预留至少60GB。用户组要创建dba和oinstall，用户名通常叫oracle，权限需设为750。这些基础设施打好，安装包才能顺利解压。"
Paragraph3 (~200 chars):
"准备好二进制包后，先创建oracle用户并加入oinstall组，然后调整ulimit值，防止安装时出现资源不足的报错。进入/Oracle/19c目录，解压软件包，确保目录权限为750。接下来，编辑oracle的.profile，加入ORACLEHOME、ORACLESID等环境变量，使系统能够识别这些路径。完成这些准备，就可以启动安装命令。"
Paragraph4 (~200 chars):
"安装过程可以采用图形化或静默模式，推荐使用静默安装因为可复制。准备好response文件，填写DBNAME、CHARACTERSET等关键参数。然后在命令行里执行./dbinstaller -silent -responsefile /path/response.rsp，期间会检查前置条件，若有缺失会提示修改。通过日志文件检查每一步是否成功，出现错误要及时回滚并重新尝试。"
Paragraph5 (~200 chars):
"数据库软件装完，需要创建监听并生成数据库实例。使用listener.axf配置端口，然后执行dbca工具，按照向导选择创建新数据库，填写SID、字符集、内存分配等信息。完成后，启动数据库实例，设置自启动脚本，确保开机后能自动恢复。密码策略要合理设置，避免后期运维麻烦。"
Paragraph6 (~200 chars):
"验证连接是否成功是关键环节。打开sqlplus，输入用户名/密码@orcl，看到提示符出现即说明网络和实例都可用。检查alert日志里没有异常报错，使用工具如SQL Developer连接进去执行一次查询，确认功能完整。如果一切正常，就算是完整的部署流程结束了，后续的优化和备份工作可以另行展开。"
Paragraph7 (~200 chars):
"整个Oracle 19c的安装其实是一套系统性的工作，从系统检查、用户配置、软件解压、静默安装到数据库创建，每一步都不可省略。只要严格按照文档要求一步步来，通常十几分钟就能把数据库搭起来。遇到问题时，及时查看安装日志和官方文档，别急着放弃。只要跟对步骤，部署成功并不难，后面的使用自然会顺手。"
Now need to ensure total characters >=1500. Let's count approximate characters per paragraph: each seems about 350-400 characters? Actually Chinese characters count each character; my paragraphs are maybe 300-400 characters each? Let's count more precisely.
I'll count characters for each paragraph manually (approx). Paragraph1 text:
"装好Oracle 19c，得把环境搭好。很多人直接点下载链接，却忽略了前期检查，结果半路卡壳。其实，把握好环境配置的每一步，后面的安装才能顺利进行。下面就把从系统准备到最终部署的全过程拆解出来，帮助你一次性把数据库搞定。"
Count characters: I'll count with spaces? Chinese punctuation counts too. Let's count manually.
装好Oracle 19c，得把环境搭好。很多人直接点下载链接，却忽略了前期检查，结果半路卡壳。其实，把握好环境配置的每一步，后面的安装才能顺利进行。下面就把从系统准备到最终部署的全过程拆解出来，帮助你一次性把数据库搞定。
Let's count: I'll copy into a counting tool mentally. But approximate: maybe 190 characters? Let's count roughly:
装(1)好2O3r4a5c6l7e8 9 1 0 ... Actually mixing English letters counts each char. Let's count precisely:

I'll count characters including punctuation and spaces? Usually spaces are characters too but we can ignore spaces? They count as characters but we can approximate. Better to aim for 200-250 characters per paragraph. My paragraphs may be longer. Let's approximate each paragraph ~250 characters. 7 paragraphs 250 = 1750 characters, meets requirement.
We must ensure no prohibited words. I used "得把环境搭好" includes "". That's prohibited: "、" are banned. Indeed "" is prohibited. Must avoid "". Also "" etc. So need to remove "". Also "" not used. In paragraph2 I wrote "常用的Linux发行版如CentOS 7或8、RHEL 7均可，前提是内核版本在3.10以上。" No banned words. Paragraph3 includes "先创建oracle用户并加入oinstall组，然后调整ulimit值，防止安装时出现资源不足的报错。" No banned words. Paragraph4 contains "可以采用图形化或静默模式，推荐使用静默安装因为可复制。" No banned. Paragraph5 includes "使用listener.axf配置端口，然后执行dbca工具，按照向导选择创建新数据库，填写SID、字符集、内存分配等信息。" No banned. Paragraph6 includes "打开sqlplus，输入用户名/密码@orcl，看到提示符出现即说明网络和实例都可用。" No banned. Paragraph7 includes "整个Oracle 19c的安装其实是一套系统性的工作，从系统检查、用户配置、软件解压、静默安装到数据库创建，每一步都不可省略。" No
