ora-12571:TNS:包写入程序失败

官方解释:

ORA-12571: TNS:packet writer failure
Cause: An error occurred during a data send.
Action: Not normally visible to the user. For further details, turn on tracing and reexecute the operation. If error persists, contact Oracle Customer Support.

解决办法1:

网上说要修改如下配置,但是我修改配置后,重启服务,仍然未解决
修改$ORACLE_HOME/network/admin/SQLNET.ORA,文件将
SQLNET.AUTHENTICATION_SERVICES=(NTS)
改为:
SQLNET.AUTHENTICATION_SERVICES=(NONE)

解决办法2:

清除警告和跟踪日志,并重启oracle服务,问题解决:

${oracle安装目录}\diag\tnslsnr\${计算机名称}\listener\alert\*.xml
${oracle安装目录}\diag\tnslsnr\${计算机名称}\listener\trace\*.xml
