oracle11g突然连不上了，ora-12514 和 ora-27101

放假前还能正常连，回来后突然应用程序启动出错，用PL/SQL一连，发现出错，ORA-12514，查baidu后说是需要修改LISTENER.ORA，该文件位于D:\app\zk\product\11.2.0\dbhome_2\NETWORK\ADMIN下，增加了几行， 变成

# listener.ora Network Configuration File: D:\app\zk\product\11.2.0\dbhome_2\network\admin\listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = CLRExtProc)

      (ORACLE_HOME = D:\app\zk\product\11.2.0\dbhome_2)

      (PROGRAM = extproc)

      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\zk\product\11.2.0\dbhome_2\bin\oraclr11.dll")

    )

    这块是新加的

    (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = D:\app\zk\product\11.2.0\dbhome_2)

      (SID_NAME = ORCL)

    ) 

    这块是新加的

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

    )

  )

ADR_BASE_LISTENER = D:\app\zk

重启一堆服务后，再连，出错，ORA-27101，再BAIDU后，说是SPFILE有问题，LOCAL_LISTENER不对，这回操作有点麻烦了

1. SQLPLUS， 用sys as sysdba连上

2. create pfile from spfile; 生成的pfile叫INITorcl.ora，位于D:\app\zk\product\11.2.0\dbhome_2\database下

3. 修改pfile里面的local_listener, 最后变成下面

*.audit_file_dest='D:\app\zk\admin\orcl\adump'

*.audit_trail='db'

*.compatible='11.2.0.0.0'

*.control_files='D:\app\zk\oradata\orcl\control01.ctl','D:\app\zk\fast_recovery_area\orcl\control02.ctl'

*.db_block_size=8192

*.db_domain=''

*.db_name='orcl'

*.db_recovery_file_dest='D:\app\zk\fast_recovery_area'

*.db_recovery_file_dest_size=4322230272

*.diagnostic_dest='D:\app\zk'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'

*.local_listener='(ADDRESS_LIST=(Address=(Protocol=tcp) (Host=127.0.0.1)(Port=1521)))'  这是修改的地方

*.memory_target=1659895808

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.undo_tablespace='UNDOTBS1'

4. create spfile from pfile="INITorcl.ora";

5. startup

终于他妈的搞定了。。。
