配置keepalive+nginx高可用的时候，启动了应用，发现连接到后台的数据库报错：
Caused by: java.sql.SQLRecoverableException: IO 错误: Socket read timed out at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:458) at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:546) at oracle.jdbc.driver.T4CConnection.<init>(T4CConnection.java:236) at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:32) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:521) at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:310)
使用pl/sql打开数据库发现连接不上，然后直接登录服务器检查：
[oracle@abc ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.1.0 Production on Wed Apr 17 14:28:58 2019 Copyright (c) 1982, 2009, Oracle. All rights reserved. ERROR: ORA-09817: Write to audit file failed. Linux-x86_64 Error: 28: No space left on device Additional information: 12 ORA-01075: you are currently logged on
发现报错：ORA-09817: Write to audit file failed.
另外有：ORA-01075: you are currently logged on
直接百度：发现ORA-01075是因为达到了最大连接数，那就直接简单粗暴：http://blog.itpub.net/29067253/viewspace-2145070/
$ ps -ef |grep $ORACLE_SID|grep -v grep|awk ‘{print $2}‘ | xargs kill -9
$ ipcs -m | grep oracle | awk ‘{print $2}‘ | xargs ipcrm shm
生产数据库千万别自己乱动！！！
然后登陆仍然报错：
[oracle@abc ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.1.0 Production on Wed Apr 17 14:35:55 2019 Copyright (c) 1982, 2009, Oracle. All rights reserved. ERROR: ORA-09817: Write to audit file failed. Linux-x86_64 Error: 28: No space left on device Additional information: 12 ORA-09945: Unable to initialize the audit trail file Linux-x86_64 Error: 28: No space left on device
没空间了：
[oracle@abc ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/vda1 30G 9.3G 19G 33% / tmpfs 16G 3.1G 13G 20% /dev/shm /dev/vdb 197G 197G 0 100% /home [oracle@abc ~]$ cd /home/
删除对应的日志文件，删除之后发现空间并未释放：
使用：lsof |grep delete，找到对应的进程杀掉就好了
（其实直接找产生日志的进程，然后重启下就好了，不用lsof |grep delete）
