抽取数据字典

create database recovery;
./stream_parser -f /data/mysql//ibdata1
 mkdir -p dumps/default
 ./c_parser -6f pages-ibdata1/FIL_PAGE_INDEX/0000000000000001.page -t dictionary/SYS_TABLES.sql > dumps/default/SYS_TABLES 2> dumps/default/SYS_TABLES.sql

 加载数据
 mysql -u root -p recovery < dictionary/SYS_TABLES.sql
 mysql -u root -p recovery < dictionary/SYS_INDEXES.sql
 mysql -u root -p recovery < dumps/default/SYS_TABLES.sql
 mysql -u root -p recovery < dumps/default/SYS_INDEXES.sql
