Dump单独一个库对象，地址是x$kglob.kglhdadr 或者 v$sql.address

随便找一个对象如下：

SQL> select sql_text,address from v$sql whererownum <2;

SQL_TEXT------------------------------------------------ADDRESS

select inst_id,hxfil, decode(hxerr,0,decode(bitand(fhsta, 1), 0,'NOT ACTIVE','A

CTIVE'), 1,'FILE MISSING', 2,'OFFLINENORMAL', 3,'NOT VERIFIED', 4,'FILE NOT FOU

ND', 5,'CANNOT OPEN FILE', 6,'CANNOT READHEADER', 7,'CORRUPT HEADER', 8,'WRONG

FILE TYPE', 9,'WRONG DATABASE', 10,'WRONGFILE NUMBER', 11,'WRONG FILE CREATE',

12,'WRONG FILE CREATE', 16,'DELAYED OPEN','UNKNOWN ERROR'), to_number(fhbsc),

to_date(fhbti,'MM/DD/RRHH24:MI:SS','NLS_CALENDAR=Gregorian'), con_id from x$kcv

fhonl

000007FF034C1000

支持3个等级DUMP。

命令如下：

SQL> oradebug dump library_cache_object 00x000007FF034C1000

得到内容如下：

Processing Oradebug command 'dumplibrary_cache_object 0 0x000007FF034C1000'
