找到相关文档Note:262996.1,经过分析,产生错误的原因是由在本版本的数据库中SGA管理中存在的漏洞造成,但此错误没有对数据库的数据造成损坏及性能影响.

处理建议
1．当前版本ORACLE已经不再提供补丁支持,建议升级到高版本解决(有sr中介绍10.2中解决);
2．由于此报错并没有对数据库的数据及性能造成损坏及影响,可以忽此错误。

问题原因

Internal triggers are trying to fire but one or more datafiles for the SYSAUX tablespace is offline, 
this is preventing the database from allowing new connections.

NOTE: At this point, you cannot connect to verify the status in V$DATAFILE, 
but you may find an indication of the offline datafile(s) in the alert.log file.

For example:
In one case, a media problem occurred which made disks unavailable.
This caused several files to be taken offline automatically including a SYSAUX datafile.

解决方法
kill进程,重启数据库到mount状态,然后根据特定情况恢复数据库或者online相关文件

总结：很明显这次出现这个问题，因为内存中出现坏块导致，经过一段时间buffer cache中的坏块内容已经被老化，所以现在不能重现(甚至不用做任何操作)。如果内存中出现了坏块，而且还没有被老化掉，可以刷新data buffer;如果是数据块出现坏块，根据实际情况决定处理

alert中ORA-00600[729]

Fri Apr  6 04:30:04 2012
Errors in file /oracle9/app/admin/crm/udump/crm2_ora_2548236.trc:
ORA-00600: internal error code, arguments: [729], [1067976], [space leak], [], [], [], [], []

a. the first bracketed number [729] is the common argument for space leak problems.
b. the second number [1067976] is the number of bytes leaked by the error.
c. the third argument is always [space leak].

a.在logoff的时候发生UGA中的session heap发生内存泄露
b.该进程是一个exp导出数据库程序，并且该程序已经被释放

出现ORA-00600[729]原因

Memory leak problems generally occur when Oracle is trying to free memory allocated to a process. 
The memory leak dump is generally discovered during session logoff, 
when Oracle frees the heaps that are allocated for the user process. 

When a user connects to Oracle, a user process is created and at that time the heap is allocated. 
Every process will have its own memory heap.

The memory is organized in to heaps and every heap consists of one or more extents. 
Each extent contains a series of contiguous memory chunks, and these chunks can be 
either FREE or ALLOCATED. The Generic Heap Manager takes care of allocating and deallocating
 the memory chunks, with the help of FREE LISTS and LRU LISTS. 

Chunk types are as follows:

1. FREE 
2. FREEABLE 
3. RECREATABLE 
4. PERMANENT 
5. FREEABLE WITH MARK 

It is not mandatory that each extent contain only one type of chunk. 
Extents can contain various types of chunks. When processes require memory chunks, 
they are allocated as needed. Oracle keeps track of the amount of memory allocated for the process internally.

When the process terminates, all of the memory that has been allocated for the process is automatically released. 
When the memory is released the allocated heaps are freed. Generally, 
when the heap is freed the only chunks that the process should identify 
as allocated are the PERMANENT chunks and FREE chunks on the freelist. 
If the process finds there are still FREEABLE or RECREATABLE chunks remaining, 
then the process has not properly deallocated the memory. 
This situation is considered a space leak.

ORA-00600[729]处理方案

1. If there are no other errors reported at the same time, 
this may be a case where the error was a rare occurrence and can be safely ignored. 
As a rule of thumb, leaks less than 90,000 bytes in size are considered to be of low significance. 
The solution in this case is to set event 10262 (see below). 

a. Set the following event in init.ora parameter file. 
   This example disables reporting for space leaks less than 90000 bytes:
event = "10262 trace name context forever, level 90000"

b. Stop and restart the database.

If the level is set to 1, space leak checking is disabled. 
This is not advised because large memory leaks will be missed.

If the event is set to a value greater than 1, 
any space leak up to the number specified in the event is ignored.

2. Is the leak in the SGA? The alert.log should be reviewed for additional 
errors such as ORA-4030 and ORA-4031 to ensure there are no additional 
problems with the shared pool or operating system memory. 

3. Does the error reproduce with a given task? If so, this is 
a case that should be investigated further because the leak could be a known bug. 
See Note 31056.1 ORA-600 [729] UGA Space Leak for a list of known bugs and fixes.

这个是oracle的一个Bug 2784796,提供解决方法有
1.run the statspack at level 0
2.restart the instance
3.set cursor sharing to exact (probably not feasible)
4.禁用主键，创建合适非唯一index

ALTER TABLE PERFSTAT.STATS$SQL_SUMMARY MODIFY 
CONSTRAINT STATS$SQL_SUMMARY_PK DISABLE NOVALIDATE;

5.修改STATS$V_$SQLXS视图
分析思路如下:
1)根据主键冲突找到主键包含列(spctab.sql)

create table          STATS$SQL_SUMMARY
(snap_id              number(6)        not null
,dbid                 number           not null
,instance_number      number           not null
,text_subset          varchar2(31)     not null
,sql_text             varchar2(1000)
,sharable_mem         number
,sorts                number
,module               varchar2(64)
,loaded_versions      number
,fetches              number
,executions           number
,loads                number
,invalidations        number
,parse_calls          number
,disk_reads           number
,buffer_gets          number
,rows_processed       number
,command_type         number
,address              raw(8)
,hash_value           number
,version_count        number
,cpu_time             number
,elapsed_time         number
,outline_sid          number
,outline_category     varchar2(64)
,child_latch          number
--注意下面5列构成主键
,constraint STATS$SQL_SUMMARY_PK primary key
    (snap_id, dbid, instance_number, hash_value, text_subset)
 using index tablespace &&tablespace_name
   storage (initial 1m next 1m pctincrease 0)
,constraint STATS$SQL_SUMMARY_FK foreign key (snap_id, dbid, instance_number)
                references STATS$SNAPSHOT on delete cascade
)tablespace &&tablespace_name
storage (initial 1m next 1m pctincrease 0) pctfree 5 pctused 40;

2)找到该表插入数据(spcpkg.sql)

insert into stats$sql_summary
            ( snap_id
            , dbid
            , instance_number
            , text_subset
            , sharable_mem
            , sorts
            , module
            , loaded_versions
            , fetches
            , executions
            , loads
            , invalidations
            , parse_calls
            , disk_reads
            , buffer_gets
            , rows_processed
            , command_type
            , address
            , hash_value
            , version_count
            , cpu_time
            , elapsed_time
            , outline_sid
            , outline_category
            , child_latch
            )
       select l_snap_id
            , p_dbid
            , p_instance_number
            , substrb(sql_text,1,31)
            , sharable_mem
            , sorts
            , module
            , loaded_versions
            , fetches
            , executions
            , loads
            , invalidations
            , parse_calls
            , disk_reads
            , buffer_gets
            , rows_processed
            , command_type
            , address
            , hash_value
            , version_count
            , cpu_time
            , elapsed_time
            , outline_sid
            , outline_category
            , child_latch
         from stats$v$sqlxs
        where is_obsolete = 'N'
          and (   buffer_gets   > l_buffer_gets_th
               or disk_reads    > l_disk_reads_th
               or parse_calls   > l_parse_calls_th
               or executions    > l_executions_th
               or sharable_mem  > l_sharable_mem_th
               or version_count > l_version_count_th
              );

3)找出stats$v$sqlxs对象(spcusr.sql)

create or replace view STATS$V_$SQLXS as
select max(sql_text)        sql_text
     , sum(sharable_mem)    sharable_mem
     , sum(sorts)           sorts
     , min(module)          module
     , sum(loaded_versions) loaded_versions
     , sum(fetches)         fetches
     , sum(executions)      executions
     , sum(loads)           loads
     , sum(invalidations)   invalidations
     , sum(parse_calls)     parse_calls
     , sum(disk_reads)      disk_reads
     , sum(buffer_gets)     buffer_gets
     , sum(rows_processed)  rows_processed
     , max(command_type)    command_type
     , address              address
     , hash_value           hash_value
     , count(1)             version_count
     , sum(cpu_time)        cpu_time
     , sum(elapsed_time)    elapsed_time
     , max(outline_sid)     outline_sid
     , max(outline_category) outline_category
     , max(is_obsolete)     is_obsolete
     , max(child_latch)     child_latch
  from v$sql
 group by hash_value, address;
create or replace public synonym STATS$V$SQLXS for STATS$V_$SQLXS;

4)通过这里可以看出，要是的STATS$SQL_SUMMARY主键不重复，只要是的STATS$V_$SQLXS查询出来的记录唯一，所以解决方案就是在STATS$V_$SQLXS视图中增加下列条件，确保查询出来的记录唯一，从而不会发生主键冲突

where 
( plan_hash_value > 0 
or executions > 0
or parse_calls > 0
or disk_reads > 0
or buffer_gets > 0
)

该bug在10g中修复，对于不能及时升级的数据库，建议采用第五种方法解决问题，比较治标治本，对业务基本上无影响
