目前运行SAS 9.3和Oracle 11.2.0.2，获得与NEFTALY相同的错误。在此之前，由于Red Hat Linux 6.3中进程/线程数量的限制而导致错误 - 内存不足。通过将限制从40000增加到90000（！）

来解决这个问题

Answer 2

错误的IP地址可能会发生此异常。因此，请检查DATABASE的绑定IP地址和连接属性。

<local-tx-datasource>
    <jndi-name>JNDI_NAME</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/DATABASE_NAME</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>root</user-name>
    <password>root</password>
    <min-pool-size>1</min-pool-size>
    <max-pool-size>10</max-pool-size>
    <idle-timeout-minutes>1</idle-timeout-minutes>
        <metadata>
         <type-mapping>mySQL</type-mapping>
      </metadata>
  </local-tx-datasource>
