2.1  在目录 ${INST_TOP}/admin/scripts/ 或 $ADMIN_SCRIPTS_HOME下可以看到：

adalnctl.sh
adapcctl.sh 
adoacorectl.sh 
adoafmctl.sh 
adformsctl.sh
adformsrvctl.sh
adforms-c4wsctl.sh
adcmctl.sh 
adopmnctl.sh

2.2 

名称: adalnctl.sh
说明: Start / Stop Applications RPC Listener process
路径: ${INST_TOP}/admin/scripts/adalnctl.sh  
用法: adalnctl.sh  {start|stop|status}  

Apps listener is different from database listener, Apps Listener is used for various 
purpose one is to check output & log files in concurrent requests. Check if apps listener 
is fine by clicking on log file & output file for Active Users request you submitted . 
If you encounter any issues while trying to access Log & Output file issue might be with 
Oracle Apps Listener.  Check if adalnctl.sh (where ad is apps dba, aln is apps listener 
and ctl is control) on application tier started successfully. If yes then check this query: 
 select  request_id, logfile_name, logfile_node_name, outfile_name, outfile_node_name 
  from fnd_concurrent_requests 
 where request_id=[your request id number].

adalnctl.sh 用于开启及关闭 apps listener (FNDFS and FNDSM). 监听文件存在于 10.1.2 ORACLE_HOME
某子目录下(注：10.1.2 ORACLE_HOME 存放Forms & Reports 等)，listener.ora确切目录为
$INST_TOP/ora/10.1.2/network/admin 

简单理解，就是你能在form界面点击查看output logfile文件，如果这个listener没起来，
是无法在form 界面点view output/view logfile来查看的。
