6.2.18 Executing a job whose executable file name has an extension longer than three bytes

Normally, the executable file specified for a job is executed by the application (.exe) associated with the executable file's extension, the maximum length of which is three bytes. Therefore, if the extension is four or more bytes, the executable file for the job^# might be opened by the wrong application or the job might not be able to start.

To correctly run a job whose executable file has an extension longer than three bytes, specify the appropriate setting by using the procedure described below.

Note that the setting must be specified on the host on which the job is executed.

#:: Refers to PC jobs and queue jobs executed on the Windows version of JP1/AJS3, and submit jobs executed by the jpqjobsub command.

(3) Notes

(1) Definition procedure

In Windows Control Panel, open the Services administrative tool, and stop the following service:
- When Standard is specified for Exec. Service of the job
  
  JP1/AJS3 service
- Queueless Agent is specified for Exec. Service of the job
  
  JP1/AJS3 Queueless Agent service
Cautionary note:

In a cluster system, check the cluster settings, and also stop the JP1/AJS3 service on each logical host.
Execute the following command to set the environment setting parameter described in (2) below:
```
jajs_config -k definition-key "parameter-name"=value
```
You can specify only one definition key. If you want to set environment setting parameters for different definition keys, you must execute the jajs_config command for each definition key.
Restart the services that you stopped in step 1.

The new settings are applied.

(2) Environment setting parameters

Table 6‒36: Environment setting parameters used to enable execution of an executable file with an extension longer than three bytes
Definition key	Environment setting parameter	Explanation
`[{JP1_DEFAULT\|logical-host}\JP1NBQAGENT\Job]`^#1	`"ENABLE_LONG_EXT"=`	This parameter applies when Standard is specified for Exec. Service of the job. The parameter specifies whether the job is to be executed by an associated application whose extension is longer than three bytes.
`[JP1_DEFAULT\JP1QLAGENT]`^#2	`"ENABLE_LONG_EXT"=`	This parameter applies when Queueless Agent is specified for Exec. Service of the job. The parameter specifies whether the job is to be executed by an associated application whose extension is longer than three bytes.

#1:: The specification of the {JP1_DEFAULT|logical-host} part depends on whether the host is a physical host or a logical host. For a physical host, specify JP1_DEFAULT. For a logical host, specify the logical host name.
#2:: This setting applies to both physical and logical hosts.

For details about the definition of this environment setting parameter, see the following:

(3) Notes

If this setting is enabled, you cannot specify any arguments following an executable file name in the Define Details dialog box for a job. If you specify arguments, the job might terminate abnormally.
Before enabling this setting, make sure that the applicable extensions of more than three bytes have been associated with applications.

The following describes how to associate an extension with an application:
1. Use the ftype command to register the application with which you want to associate an extension.
2. Use the assoc command to associate the extension with the application you registered in step 1.
3. Restart the OS.
For details about the ftype and assoc commands, see Windows Help.
