生产库出现ora-12518

1^#

发表于 2012-3-29 10:39:15 | 查看: 6007| 回复: 5

oracle: 10.2.0.5 3节点RAC
今早生产库无法远程连接，使用的是sql developer+ service name登陆，报告ora-12518错误；但是如果换成SID，则可以正常登陆；
登陆server采用sqlplus [email=***/***@dbname]***/***@dbname[/email]的方式可以正常登陆；
数据库采用的是dedicate连接，且process值设置为1000，远远高于现有连接会话数
alert log没有错误信息，listener log也没有错误信息；
查看listener service发现有会话可以陆续连接进入数据库

请Maclean帮忙诊断一下
谢谢

oracle:  10.2.0.5  3节点RAC
OS： AIX 6
症状：客户早上报告连接数据库总是报告ora-12518，因为是生产库所以十分紧急；经过一番尝试发现以下情况：
1 客户使用如下tnsname连接
justin=
  (DESCRIPTION =
(ADDRESS_LIST=
(ADDRESS = (PROTOCOL = TCP)(HOST = justin98-vip..aaaa.net)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = justin99-vip..aaaa.net)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = justin100-vip..aaaa.net)(PORT = 1521))
)
(CONNECT_DATA =
      (SERVICE_NAME = justin)
)
)

2 自己使用sql developer尝试连接
当使用service_names连接时，总是抱错ora-12518；使用sid则能正常连接

3 登陆server
运行sqlplus ***/***@justin.world总是能够成功登陆

4 登陆justin98上的数据库
查看gv$session_wait没有发现严重latch，且各节点的pga都有一定空余(三节点都是使用dedicated server)
该节点上的listener.log没有任何错误信息

5 查看 listener service
结果显示3节点都有session陆续连接进来
Service "justin.world" has 3 instance(s).
  Instance "justin1", status READY, has 2 handler(s) for this service...
Handler(s):
   "DEDICATED" established:0 refused:0 state:ready
      REMOTE SERVER
      (ADDRESS=(PROTOCOL=TCP)(HOST=justin98-vip..aaaa.net)(PORT=1521))
   "DEDICATED" established:133 refused:0 state:ready
      LOCAL SERVER
  Instance "justin2", status READY, has 1 handler(s) for this service...
Handler(s):
   "DEDICATED" established:153 refused:0 state:ready
      REMOTE SERVER
      (ADDRESS=(PROTOCOL=TCP)(HOST=justin99-vip..aaaa.net)(PORT=1521))
  Instance "justin3", status READY, has 1 handler(s) for this service...
Handler(s):
   "DEDICATED" established:58 refused:0 state:ready
      REMOTE SERVER
      (ADDRESS=(PROTOCOL=TCP)(HOST=aaa100-vip..aaaa.net)(PORT=1521))

最后经过一番尝试，发现justin99无法ssh登陆，初步怀疑是该节点无法接受客户端请求导致的ora-12518

验证
配置Sqlnet进行客户端跟踪
TRACE_LEVEL_CLIENT =16
TRACE_FILE_CLIENT=CLIENT
trace_directory_client=/orasw/dba/tep123

然后尝试不同tnsname配置下登陆
1
justin.world=
  (DESCRIPTION =
(ADDRESS_LIST=
(ADDRESS = (PROTOCOL = TCP)(HOST = justin98-vip..aaaa.net)(PORT = 1521))
# (ADDRESS = (PROTOCOL = TCP)(HOST = justin99-vip..aaaa.net)(PORT = 1521))
# (ADDRESS = (PROTOCOL = TCP)(HOST = aaa100-vip..aaaa.net)(PORT = 1521))
)
(CONNECT_DATA =
#       (SERVICE_NAME = justin.world)
      (sid = justin1)
)
)

连接正常，登陆了节点1
