处理SDE服务无法启动案例简记
环境:
OS: Redhat 4.0 AS
DBMS:oracle10.2.0.4.0
ArcSDE9.3 for oracle 10g
启动错误提示如下:
在sde用户下：
------------------------------------------------------- ArcSDE 9.3 for Oracle10g Build 508 Thu Apr 17 12:23:18 2008 -------------------------------------------------------
DB_open_instance()::db_connect (OCI8) error:
1034 init_DB DB_instance_open_as_dba: -51
DBMS error code: 1034 ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment Linux Error: 13: Permission denied
Could not start ArcSDE -- Check Network, $SDEHOME disk, DBMS settings and dbinit.sde.
使用sqlplus连接，出现如下错误，和启动sde服务错误一致
[sde@test1 ~]$ sqlplus sde/sde
SQL *Plus: Release 10.2.0.4.0 - Production on Mon Jan 18 17:27:41 2010

ERROR:
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux Error: 13: Permission denied
查看oracle的共享内存：
[sde@test1 ~]$ ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0xccc7f63c 360449 oracle 640 1260388352 19
共享内存已经开辟出来，然后切换到oracle用户下：
[oracle@test1 ~]$ sqlplus sys as sysdba
SQL *Plus: Release 10.2.0.4.0 - Production on Mon Jan 18 17:21:46 2010

OPEN_MODE

READ WRITE
数据库的处于打开状态，现在基本上确定了是sde用户没有权限访问oracle的共享内存，问题应该出现在启动oracle实例的文件上，该文件为$ORACLE_HOME/bin/oracle，查看该文件的权限
1:
[oracle@test1 ~]$ cd $ORACLE_HOME/bin
2:
[oracle@test1 bin]$ ls -l oracle
3:
-rwxrwxrwx 1 oracle oinstall 96789104 11-25 12:47 oracle
4:
[oracle@test1 bin]$
文件的权限为777，缺少s权限,把s权限赋给oracle文件
chmod a+s oracle
重启oracle实例:
[oracle@test1 bin]$ sqlplus sys as sysdba
