   -> 大数据 -> oracle RAC 集群无法启动 -> 正文阅读

[大数据]oracle RAC 集群无法启动

RDBMS 11.2.0.4

节点1无法启动，节点2 启动正常。

节点1的集群状态一直这样

[grid@ractest1 admin]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager

但是节点2的集群状态是正常的。重启节点1和节点2 ，问题依旧。

在关闭节点1的集群的时候，提示没有集群，加参数 -f后强制可以关闭。

查看节点1的相关log ：

尝试启动asm实例，报错

MOS上搜文档，查到相关文档：11gR2 ASM Fails to Start With "ORA-12547: TNS:lost contact" and ORA-12649 due to Incorrect Network Security Setting (Doc ID 1505025.1)

与该文档中的相关日志进行对比，一抹一样。

该文档定位为grid用户下的sqlnet.ora中设置了加密。查看相关内容，果然加密

[grid@ractest1 admin]$ more sqlnet.ora
# sqlnet.ora.ractest1 Network Configuration File: /u01/app/grid/network/admin/sqlnet.ora.ractest1
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = /u01/app/gridbase

#SQLNET.ENCRYPTION_SERVER = REQUIRED
#SQLNET.ENCRYPTION_TYPES_SERVER = RC4_256
#SQLNET.CRYPTO_CHECKSUM_SERVER = REQUIRED
#SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER = RC4_256
[grid@ractest1 admin]$

另一个节点就没有加密：

[grid@ractest2 admin]$ more sqlnet.ora 
# sqlnet.ora.ractest2 Network Configuration File: /u01/app/grid/network/admin/sqlnet.ora.ractest2
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = /u01/app/gridbase

[grid@ractest2 admin]$

根据mos上的说明，屏蔽掉加密，再次启动，正常启动。问题解决。

CAUSE

sqlnet.ora changed in $TNS_ADMIN or $GRID_HOME/network/admin directory?to add encryption, i.e.?

SQLNET.ENCRYPTION_TYPES_SERVER={3DES168}
SQLNET.ENCRYPTION_SERVER=REQUIRED

SOLUTION

Restore sqlnet.ora from backup and start ASM from sqlplus.
