由于希望测试一个DG问题，所以在Vmware上搭建测试环境，primary和standby放在同一台主机上。
搭建过程就不赘述，，但是在最后，遇到了一些问题，这里记录一下，以备后续查阅。

----搭建过程中的一些命令-----

1. backup database format '/tmp/bk_%U'; 2. backup current controlfile for standby format '/tmp/stdbyctl.bkp'; 3. catalog start with '/tmp/'; 4. set controlfile autobackup format for device type disk to '/tmp/%F'; restore standby controlfile from '/tmp/stdbyctl.bkp'; 5. RMAN> CONNECT TARGET SYS/oracle@db; RMAN> CONNECT AUXILIARY SYS/oracle@stddb;

6. 最会std的pfile文件内容

db_file_name_convert= '+data/db/','+reco/stddb/' log_file_name_convert= '+RECO/db/archivelog/','+RECO/stddb/archivelog_std/' log_archive_format=%t_%s_%r.arc standby_file_management=auto compatible='11.2.0.0.0' control_files='+RECO/stddb/controlfile/current.260.834947597' 问题一：

在设置listener的过程中，由于设定静态监听，在standby启动之后，同时又会注册一个动态监听，目前有两个监听，其中动态监听状态为blocked。
遇到的问题就是，在duplicate连接的时候，就会发生ORA-12528错误，而不能正常连接到standby。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [oracle@OEL ~]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 30-DEC-2013 10:46:03 Copyright (c) 1991, 2009, Oracle.

Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521)) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for Linux: Version 11.2.0.1.0 - Production Start Date 27-NOV-2013 12:40:26 Uptime 32 days 22 hr. 5 min. 37 sec Trace Level off Security ON: Local OS Authentication SNMP OFF Listener Parameter File /u01/app/11.2.0/grid/network/admin/listener.ora Listener Log File /u01/app/oracle/diag/tnslsnr/OEL/listener/alert/log.xml Listening Endpoints Summary...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ stddb = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = OEL.localdomain)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = stddb)(UR=A)) 问题二：

在执行下面命令之后，直接primary就crash掉，经过查询alert发现，是redo broken导致的
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

查询standby alert，发现如下信息：
（在ALTER DATABASE RECOVER...开始之后，第一件事情就是clear redo log，这样就直接导致primary crash）

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # tail -f alert_stddb.log Clearing online redo logfile 1 complete Clearing online redo logfile 2 +DATA/db/redo02.log Clearing online log 2 of thread 1 sequence number 5 Clearing online redo logfile 2 complete Clearing online redo logfile 3 +DATA/db/redo03.log Clearing online log 3 of thread 1 sequence number 3 Tue Dec 24 14:32:49 2013 Clearing online redo logfile 3 complete Tue Dec 24 14:32:49 2013 Media Recovery Waiting for thread 1 sequence 4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

在重建几次之后，问题依然。
由于datafile和archivelog都使用convert参数转换了，但是redo是无法转换的，如何解决这个问题呢？
经过分析，发现在duplicate的最后，有一些警告信息：

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
