目前在使用WebLogic12C的时候，常见系统后台报日志
clock GMT Warning Server rds09470app145 rdms1-restgp2b DynamicListenThread[Default] WLS Kernel 1386360183611 BEA-002631 Max threshold reached for open sockets [total open sockets: 1,000, allowed max: 1,000]. No more connections allowed.

这个经过分析，需要进行打补丁处理

Solution retained by this customer is to drop MAX-OPEN-SOCK-COUNT and to apply the known workaround against the deadlock. The other solution is to install the following patches on WLS 12.1.2:

• Patch 18108916
• Patch 18289179
• Patch 16784672

1：下载补丁
p16784672_121200_Generic.zip
p18108916_121200_Generic.zip
p18289179_121200_Generic.zip

2：将补丁进行解压，解压到目录
----PATCH_TOP/16784672

3: 设置JDK环境变量
export  JAVA_HOME=/weblogic/jdk1.7.0_15
export  JAVA_BIN=/weblogic/jdk1.7.0_15/bin
export  PATH=$JAVA_HOME/bin:$PATH
export  CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

4：设置oracle_home 既 weblogic_home
export ORACLE_HOME=/weblogic/wls1212

5: 打补丁

#cd PATCH_TOP/16784672
#/weblogic/wls1212/OPatch/opatch apply -jdk $JAVA_HOME

[weblogic@localhost 18289179]$ /weblogic/wls1212/OPatch/opatch apply -jdk $JAVA_HOME
