asm的静态注册listener居然是区分大小写的

SID_LIST_LISTENER2 =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl.beikan)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0/db_1)
      (SID_NAME = orcl)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl2.beikan)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0/db_1)
      (SID_NAME = orcl)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = pdborcl.beikan)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0/db_1)
      (SID_NAME = orcl)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = pdborclasm.beikan)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0/db_1)
      (SID_NAME = orcl)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = +ASM)
      (ORACLE_HOME = /u01/app/grid/product/12.1.0/grid)
      (SID_NAME = +ASM)
    )
  )

LISTENER2 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1523))
      (ADDRESS = (PROTOCOL = TCP)(HOST = orasrv.beikan)(PORT = 1523))
    )
  )

我用小写启动listner2后，是连不上的。当然tnsname.ora里不区分大小写。
