Oracle 12C数据库报ORA-7445 [qcdlgcd] ,前台报No more data to read from socket错误解决方法

问题描述:

  1. 在EAS Cloud8.6+Oracle 12.1.0.2环境中, 执行EAS Cloud凭证新增,在物料选择时,弹出F7功能报错,报No more data to read from socket错误。

  2. 通过几家客户验证,只要用了Oracle 12.1.0.2数据库,做了大数据量的查询,都触发了No more data to read from socket报错。


解决方案:

1.查看客户端的client\logs\log4j.log、服务端\eas\server\profiles\server*\logs\apusic.log日志可见如下详细报错:

java.sql.SQLException: No more data to read from socket

at oracle.jdbc.driver.T4CMAREngine.unmarshalUB1(T4CMAREngine.java:1157)

at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:350)

at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:227)

at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:531)

at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:208)

at oracle.jdbc.driver.T4CPreparedStatement.executeForDescribe(T4CPreparedStatement.java:879)

at oracle.jdbc.driver.OracleStatement.executeMaybeDescribe(Unknown Source)

at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(Unknown Source)

at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3608)

at oracle.jdbc.driver.OraclePreparedStatement.executeQuery(OraclePreparedStatement.java:3652)

at oracle.jdbc.driver.OraclePreparedStatementWrapper.executeQuery(OraclePreparedStatementWrapper.java:1207

2.查看数据库的警告日志alert*.log,发现以下报错:ORA-07445: 出现异常错误: 核心转储 [qcdlgcd()+70] [SIGSEGV] [ADDR:0x4] [PC:0xCDFB0D6] [Address not mapped to object]

经查询是触发了Oracle 12.1.0.2版本上的BUG,其BUG号是20830993 (匹配Bug 20830993 - ORA-7445 [qcdlgcd] reported while running select statement - superseded (文档 ID 20830993.8))

修改以下隐含参数:

alter session set "_index_join_enabled"=false;

改参数后问题得到解决。Oracle 12.1.0.2版本较低,BUG较多,建议数据库升到ORACLE 19C(即12.2.0.3)。
