+# Error When Writing Illegal Characters
+
+## Availability
+
+This feature is available since MogDB 5.0.2.
+
+## Introduction
+
+Supports error reporting for input data not conforming to encoding rules when the server and client character set encodings are the same.
+
+## Benefits
+
+Output illegal character set error message to facilitate users to repair the fault in time to ensure the normal operation of the system.
+
+## Description
+
+Currently, when the server-side and client-side encoding is the same, data written through JDBC and other means will be modified to '?' by default if illegal characters appear. and there is no prompt message, resulting in mismatch between the actual data written and the expected data.
+
+MogDB 5.0.2 version added session level USERSET type parameter emit_illegal_bind_chars, which is used to control whether to report error for illegal characters. The default value of this parameter is off, which is compatible with the behavior of the old version (no error reporting). Change the parameter value to on to enable error reporting.
+
+## Constraints
+
+This feature is only related to the server-side and client-side character set is consistent, through the JDBC and other client-side PBE mode execution and the number of parameters is greater than 0, illegal characters in the parameters to report an error, the following cases are not within the scope of this feature:
+
+1. the character set is the same, but the number of parameters is 0, for the illegal characters in the statement, the current behavior is already an error.
+2. statements executed via gsql, etc., where the behavior is already an error.
+3. the behavior of the copy statement is controlled by COMPATIBLE_ILLEGAL_CHARS, which is out of the scope of this feature.
+4. When the server-side and client-side character sets do not match, whether or not to report an error is determined by the conversion function, and is not within the scope of this feature.
+
+## Examples
+
+Create test database and table for use in subsequent DML statements.
+
+`````sql
+CREATE DATABASE db_gbk TEMPLATE template0 encoding 'GBK' lc_ctype 'zh_CN.GBK' lc_collate 'zh_CN.GBK';
+
+CREATE TABLE test (a integer,b character varying);
+`````
+
+Using Go as an example, write code that connects to a database and executes a DML statement.
+
+```go
+package main
+
+import (
+    "database/sql"
+    "encoding/hex"
+    _ "github.com/lib/pq"
+)
+
+func main() {
+    db, err: = sql.Open("postgres", "port=5434 user=test password=Qwer1234 dbname=db_gbk sslmode=disable")
+    checkErr(err)
+    defer db.Close()
+    _, err = db.Exec("set client_encoding = 'GBK'");
+    checkErr(err)
+    _, err = db.Exec("set emit_illegal_bind_chars = on")
+    checkErr(err)
+    s: = "8139EF31"
+    b, _: = hex.DecodeString(s)
+    _, err = db.Exec("insert into test values ($1, $2)", 1, string(b))
+    checkErr(err)
+}
+
+func checkErr(err error) {
+    if err != nil {
+        panic(err)
+    }
+}
+```
+
+An error was reported:
+
+`````go
+panic: pq: invalid byte sequence for encoding "GBK": 0x81 0x39
+
+goroutine 1 [running]:
+main.checkErr(...)
+        /home/test/Documents/test_go/main.go:25
+main.main()
+        /home/test/Documents/test_go/main.go:20 +0x225

+# Support For Pageinspect & Pagehack
+
+## Availability
+
+This feature is available since MogDB 5.0.2.
+
+## Introduction
+
+New pageinspect and pagehack tools are used to assist in locating related issues. pageinspect is an extension, after installation to create extension to use, pagehack is an executable tool, need to be installed on the command line to use.
+
+## Benefits
+
+The new tool is only available to front-line maintenance, testers, and developers for internal use in locating problems.
+
+## Description
+
+### pageinspect
+
+This extension implements in the row-store table (astore) scenario to view the data file and Btree index file related page content information, belongs to the online query (MogDB use case ALIVE), in the SQL side of the execution of the relevant commands to view the information.
+
+Pageinspect is an extension, you need to install manually, before installation, please download the released Toolkits in [official website download page](https://www.mogdb.io/downloads/mogdb/), unpack the corresponding files and copy them to the specified directory and change the permissions. Log in to the database and create the extension.
+
+```bash
+# Unpack the toolkit with the root user
+tar -xzvf Toolkits-5.0.2-Kylin-arm64.tar.gz
+
+# Use the database instance user (e.g., omm), go to the pageinspect folder under toolkits and copy the appropriate files to the specified directory
+cd pageinspect/
+cp pageinspect--1.0.sql $GAUSSHOME/share/postgresql/extension
+cp pageinspect.control $GAUSSHOME/share/postgresql/extension
+cp pageinspect--unpackaged--1.0.sql $GAUSSHOME/share/postgresql/extension
+cp pageinspect.so $GAUSSHOME/lib/postgresql
+
+# Modify permissions
+cd $GAUSSHOME/share/postgresql/extension
+chmod 644 pageinspect--1.0.sql pageinspect.control pageinspect--unpackaged--1.0.sql
+cd $GAUSSHOME/lib/postgresql
+chmod 755 pageinspect.so
+
+# Log into the database and create extension
+gsql -r
+CREATE EXTENSION pageinspect;
+```
+
+The extension provides several system functions to query using a fixed format with the following syntax:
+
+```sql
+# View the contents of the heap data table
+SELECT * FROM heap_page_iteme(get_raw_page('table_name','main',page_no));
+# View header information on a heap page
+SELECT * FROM page_header(get_raw_page('table_name','main',page_no));
+# View meta page information
+SELECT * FROM bt_metap('index_name');
+# View the contents of the specified index page number
+SELECT * FROM bt_page_items('index_name', page_no);
+```
+
+### pagehack
+
+The pagehack tool is used to parse offline files generated by row-store tables and BTree indexes created in MogDB instances. Pagehack is a binary executable tool executed directly on the terminal command line, with parameters for the files to be parsed (row-store tables and BTree index files are supported), displaying the specific data content of the page in the file. This tool needs to be installed manually, the method is as follows:
+
+```bash
+# Unpack the toolkit with the root user
+tar -xzvf Toolkits-5.0.2-Kylin-arm64.tar.gz
+
+# Use the database instance user (e.g., omm), go to the pagehack folder under toolkits and copy the appropriate files to the specified directory
+cd pagehack/
+cp pagehack $GAUSSHOME/bin
+cp pagehack.so $GAUSSHOME/lib/postgresql
+
+# Modify permissions
+cd $GAUSSHOME/bin
+chmod 755 pagehack
+cd $GAUSSHOME/lib/postgresql
+chmod 755 pagehack.so
+```
+
+Once the installation is complete, execute the following command directly to use the tool:
+
+```bash
+pagehack -f [filename]
+```
+

-# Use Data Studio to Access MogDB
-
-This document introduces how to access MogDB through Data Studio.
-
-<br/>
-
-## Introduction
-
-**Data Studio** is an Integrated Development Environment (IDE) that helps database developers build the application conveniently. It supports essential features of the database.
-This tool allows working with database objects with minimal programming knowledge. Data Studio provides you with various features, such as
-
-- creating and managing database objects
-- executing SQL statements or SQL scripts
-- editing and executing PL/SQL statements
-- viewing the execution plan and cost through the GUI
-- exporting table data
-
-The database objects that are created and managed include
-
-- database
-- schema
-- function
-- procedure
-- table
-- sequence
-- index
-- view
-- tablespace
-- synonym
-
-It also provides SQL assistance for various queries/procedures/functions executed in the SQL Terminal and PL/SQL Viewer.
-

+
+# 写入不合法字符报错
+
+## 可获得性
+
+本特性自MogDB 5.0.2版本开始引入。
+
+## 特性简介
+
+支持在服务端和客户端字符集编码一致时，针对输入的数据不符合编码规则的情况进行报错。
+
+## 客户价值
+
+输出非法字符集报错信息，方便用户及时修复故障，保证系统正常运行。
+
+## 特性描述
+
+当前在服务端和客户端编码一致时，通过JDBC等方式写入的数据，如果出现非法字符，会被默认修改为 ‘?’ 存储，且没有提示信息，导致实际写入数据与期望数据不匹配。
+
+MogDB 5.0.2版本新增session级别USERSET类型参数emit_illegal_bind_chars，用于控制是否针对不合法字符进行报错。该参数默认值为off，兼容旧版本行为（不报错）。修改参数值为on，即可开启报错功能。
+
+## 特性约束
+
+本特性仅涉及在服务端和客户端字符集一致的情况下，通过JDBC等客户端里PBE模式执行且参数个数大于0，参数中出现非法字符时报错，以下情形不在此特性范围内：
+
+1. 字符集一致，但参数个数为0，针对语句中出现的非法字符，目前行为已经是报错
+2. 通过gsql等方式执行的语句，目前行为已经是报错
+3. copy语句的行为由COMPATIBLE_ILLEGAL_CHARS控制，不在此特性范围内
+4. 服务端和客户端字符集不一致时，是否报错由转换函数决定，不在此特性范围内
+
+## 示例
+
+创建测试数据库、表，用以后续的DML语句使用。
+
+`````sql
+CREATE DATABASE db_gbk TEMPLATE template0 encoding 'GBK' lc_ctype 'zh_CN.GBK' lc_collate 'zh_CN.GBK';
+
+CREATE TABLE test (a integer,b character varying);
+`````
+
+以Go为例，编写代码，连接到数据库，并执行DML语句。
+
+```go
+package main
+
+import (
+    "database/sql"
+    "encoding/hex"
+    _ "github.com/lib/pq"
+)
+
+func main() {
+    db, err: = sql.Open("postgres", "port=5434 user=test password=Qwer1234 dbname=db_gbk sslmode=disable")
+    checkErr(err)
+    defer db.Close()
+    _, err = db.Exec("set client_encoding = 'GBK'");
+    checkErr(err)
+    _, err = db.Exec("set emit_illegal_bind_chars = on")
+    checkErr(err)
+    s: = "8139EF31"
+    b, _: = hex.DecodeString(s)
+    _, err = db.Exec("insert into test values ($1, $2)", 1, string(b))
+    checkErr(err)
+}
+
+func checkErr(err error) {
+    if err != nil {
+        panic(err)
+    }
+}
+```
+
+执行报错：
+
+`````go
+panic: pq: invalid byte sequence for encoding "GBK": 0x81 0x39
+
+goroutine 1 [running]:
+main.checkErr(...)
+        /home/test/Documents/test_go/main.go:25

+# 支持pageinspect和pagehack工具
+
+## 可获得性
+
+本特性自MogDB 5.0.2版本开始引入。
+
+## 特性简介
+
+新增pageinspect和pagehack工具用于辅助相关问题定位。pageinspect是一款插件(extension)，安装后创建插件使用，pagehack是一个可执行工具，需安装后在命令行使用。
+
+## 客户价值
+
+新增工具仅提供给一线维护人员、测试人员以及开发人员用于定位问题内部使用。
+
+## 特性描述
+
+### pageinspect插件
+
+本插件实现在行存表(astore)场景下查看数据文件和Btree索引文件相关page页面的相关内容信息，属于在线查询（MogDB用例alive），在SQL端执行相关命令查看信息。
+
+pageinspect工具是一款插件(extension)，需要手动安装，安装前请在[官网下载页面](https://www.mogdb.io/downloads/mogdb/)下载已发行的Toolkits工具包，解压后将相应的文件拷贝到指定目录下并修改权限，登录数据库并创建extension即可。
+
+```bash
+# 使用root用户解压缩工具包
+tar -xzvf Toolkits-5.0.2-Kylin-arm64.tar.gz
+
+# 使用数据库实例用户（如omm）进入toolkits下的pageinspect文件夹，拷贝相应的文件到指定目录
+cd pageinspect/
+cp pageinspect--1.0.sql $GAUSSHOME/share/postgresql/extension
+cp pageinspect.control $GAUSSHOME/share/postgresql/extension
+cp pageinspect--unpackaged--1.0.sql $GAUSSHOME/share/postgresql/extension
+cp pageinspect.so $GAUSSHOME/lib/postgresql
+
+# 修改权限
+cd $GAUSSHOME/share/postgresql/extension
+chmod 644 pageinspect--1.0.sql pageinspect.control pageinspect--unpackaged--1.0.sql
+cd $GAUSSHOME/lib/postgresql
+chmod 755 pageinspect.so
+
+# 登录数据库，创建extension
+gsql -r
+CREATE EXTENSION pageinspect;
+```
+
+该插件提供几个系统函数，使用固定格式进行查询，语法如下：
+
+```sql
+# 查看heap数据表中内容
+SELECT * FROM heap_page_iteme(get_raw_page('table_name','main',page_no));
+# 查看heap页面的header信息
+SELECT * FROM page_header(get_raw_page('table_name','main',page_no));
+# 查看meta page信息
+SELECT * FROM bt_metap('index_name');
+# 查看指定索引page页面号的内容
+SELECT * FROM bt_page_items('index_name', page_no);
+```
+
+### pagehack工具
+
+pagehack工具用于对MogDB实例中创建的行存表和BTree索引产生的离线文件进行解析。pagehack是一个二进制可执行工具，直接在终端命令行执行，参数为需要解析的文件（支持行存表和BTree索引文件），显示文件中page页面具体数据内容。本工具需手动安装，方法如下：
+
+```bash
+# 使用root用户解压缩工具包
+tar -xzvf Toolkits-5.0.2-Kylin-arm64.tar.gz
+
+# 使用数据库实例用户（如omm）进入toolkits下的pagehack文件夹，拷贝相应的文件到指定目录
+cd pagehack/
+cp pagehack $GAUSSHOME/bin
+cp pagehack.so $GAUSSHOME/lib/postgresql
+
+# 修改权限
+cd $GAUSSHOME/bin
+chmod 755 pagehack
+cd $GAUSSHOME/lib/postgresql
+chmod 755 pagehack.so
+```
+
+安装完成后，直接执行以下命令即可使用工具：
+
+```bash
+pagehack -f 文件名
+```
+
+## 示例
+
+### pageinspect
+
+```sql
+# 创建pageinspect插件，然后创建行存表和BTree索引,在数据表中插入若干数据
+MogDB=# CREATE EXTENSION pageinspect;
+CREATE EXTENSION
