ORA-600 kcratr_nab_less_than_odr故障解决

发表于 2012 年 1 月 11 日由惜分飞

朋友的数据库服务器出现ORA-00600[kcratr_nab_less_than_odr]，不能open数据库
1.open数据库报ORA-00600[kcratr_nab_less_than_odr]

SQL> ALTER DATABASE OPEN;

2.查看alert日志

3.查看trace文件

Trace file d:\dbdms\diag\rdbms\dbdms\dbdms\trace\dbdms_ora_3108.trc

ORA-00600: ??????, ??: [kcratr_nab_less_than_odr], [1], [99189], [43531], [43569], [], [], [], [], [], [], []

通过alert和trace中的内容可以知道，数据库需要恢复到rba到43569，但是因为某种原因实例恢复的时候，只能利用1 thread 99189 seq#，恢复rba到43531。从而导致数据库无法正常open

This Problem is caused by Storage Problem of the Database Files. 
The Subsystem (eg. SAN) crashed while the Database was open. 
The Database then crashed since the Database Files were not accessible anymore. 
This caused a lost Write into the Online RedoLogs and so Instance Recovery is not possible and raising the ORA-600.

在这次恢复中，主要就是重建控制文件，然后直接恢复成功，如果redo有损坏，那么可能需要使用不完全恢复，然后使用resetlogs打开数据库

通过undo_retention保留时间为10800秒，而该sql执行了49146秒，在这49146秒钟，TAB_XN_COMPANY表中的数据被修改，而且被修改的undo数据在10800秒后被覆盖导致，导致原查询语句不能获取到scn小于或者等于查询时候的数据块内容(在undo中)，所以出现ORA-01555。从这里也可以看出来，在undo空间还剩余的情况下，如果超过了undo_retention限制，undo内容还是有可能被覆盖，而不是使用未使用的undo

三.出现ORA-1555原因
The ORA-1555 errors can happen when a query is unable to access enough undo to build a copy of the data at the time the query started. Committed “versions” of blocks are maintained along with newer uncommitted “versions” of those blocks so that queries can access data as it existed in the database at the time of the query. These are referred to as “consistent read” blocks and are maintained using Oracle undo management.
就是一个查询要访问某个数据块，而这个数据块在这个查询执行过程中修改过，那么该查询需要查询undo中数据块，而undo中该数据块已经不存在，从而出现ORA-1555

四.ORA-1555解决方法
Case 1 – Rollback Overwritten
1.缩短sql运行时间
2.增加undo_retention，这个同时需要考虑undo空间大小
3.减少commit(rollback)次数
4.在一条sql中尽量使数据块访问一次
4.1)Using a full table scan rather than an index lookup
4.2)Introducing a dummy sort so that we retrieve all the data, sort it and then sequentially visit these data blocks.

Case 2 – Rollback Transaction Slot Overwritten
这种问题，主要是延迟块清理导致，一般建议在进行大批量的dml操作后，使用全表(全index)扫描执行一遍，或者收集全部统计信息

四.在MOS上找到相关文章[ID 1298804.1]

Applies to:

Oracle Server - Enterprise Edition - Version: 11.1.0.6 to 11.1.0.7 - Release: 11.1 to 11.1
Information in this document applies to any platform.
Symptoms

The following errors are seen in the trace file written by an ORA-7445 [kslgetl]:

network error encountered getting listening address:
NS Primary Error: TNS-12533: TNS:illegal ADDRESS parameters
NS Secondary Error: TNS-12560: TNS:protocol adapter error
NT Generic Error: TNS-00503: Illegal ADDRESS parameters
OPIRIP: Uncaught error 108. Error stack:
ORA-00108: failed to set up dispatcher to accept connection asynchronously
Exception signal: 11 (SIGSEGV), code: 1 (Address not mapped to object), addr: 0x130, PC: [0x82f09dc, kslgetl()+80]

The trace file indicates that there is no session:

Current SQL information unavailable - no session.

The Call Stack Trace in the ORA-7445 trace file contains a function list similar to:

 kslgetl <- PGOSF57_ksfglt
<- kghfre <- kmnsbf <- nsbfr <- nsiofrrg <- nsiocancel
<- nsopen_shutitdown <- nsclose <- nsgblclose <- nsgblTRMHelper <- nsgblRealTerm
<- nlstdstp <- npinlt <- ksuabt <- opidrv <- sou2o
<- opimai_real <- main <- libc_start_main

Cause

The trace file first reports: Warning: keltnfy call to ldmInit failed with error 46 

The ORA-7445 is not the starting point here. This exception is just a spin-off from ORA-180 and it is possible that different internal errors may be seen, such as ORA-600 [504], depending on what is happening when the ORA-180 is encountered.

The cause for the ORA-180 is related to the inital message at the beginning of the trace file: "keltnfy call to ldmInit failed with error 46" and this is followed by: "network error encountered getting listening address:" 

The error code (here: 46) is the key for solving the issue.
This warning says that ldmInit() returned error 46 which is LDMERR_HOST_NOT_FOUND (host not found).

This error is returned if the OS call gethostbyname() fails with an error. So these appears to be a network specific issue.
Solution

1) Check permission on /etc/hosts

$ ls -l /etc/hosts -rw-r--r-- 2 root root 194 Oct 17 2006 /etc/hosts


Check if /etc/hosts file is correctly configured


<ip address> <fully qualified hostname> <simple or short hostname> <alias, if applicable> ( all of this on one line ).


2) Check the hostname:

$ hostname
$ ping `hostname`

Make sure you are able to ping the hostname


3) Check if /etc/nodename is correctly configured
If you have DNS setup, ping is not a tool to diagnose DNS problem. A better tool to use is nslookup, dnsquery, or dig.


$ nslookup <shortname> $ nslookup <long name> $ nslookup <ip address>

The forward and reverse lookup should succeed and return consistent address/info.


4) Check nsswitch.conf


$ more nsswitch.confhosts: files dnsMake sure host lookup is also done through the /etc/hosts file and not just dns. It is recommended that FILES come first before DNS.


Also, check the resolv.conf. This makes sure that the DNS is working properly.

在这里看到虽然数据库的版本不一样，alert和trace中的错误不完全一致，但是很相似。是由于主机名不能被正常访问导致，所以尝试这从主机名相关部分着手解决。

五.查看主机名相关信息，解决问题
