Hi,

I need to call a ITX map form within a shell script. The map should do the following:

• The script should run an  ITX map (mmc file)
• The map started should continue to use ITX configuration file (config.mrn). The variable put on the map will be replaced by the file from the configuration file.
• The script should return the value "1" if it's failed or just echo when it's OK. 

Any help would be greatly appreciated.

You need to use the Command Server (dtxcmdsv).  The Resource Registry file MRC will be picked up if you have referenced it in both place in the dtx.ini file.  The MRC file will use the MRN file referenced in the Command Server section.

Usual errorlevel checking can be used, as per any other type of script.

Thank you.

Thank You Response Paul. 

Can you please elaborate on what it means by referencing the MRC file in both the place in dtx.ini file. 

I have used the dtxcmdsv command server command: My script is pasted below:

The below script fails to pickup values from the config.mrn file. Please suggest.

Did you open and view the file?  In dtx.ini you will find:

; this defines what resource configuration file to use for the Command Server:                                    
;ResourceCfgFile=resource.mrc

and

; this defines what resource configuration file to use for the Launcher:
;ResourceCfgFile=resource.mrc

I recommend you set the location of your MRC file in both these places (and remove the semi colon to un-comment the lines).  Example:

; this defines what resource configuration file to use for the Command Server:                                    
ResourceCfgFile=/opt/IBM/itx900/config/resource.mrc

Thank you.

Hi Paul,

The shell script pasted above works, but it doest return the correct error code when it fails. I am trying to call a series of maps using shell. My Shell script will call the first map which will consequently call the second map. 

Now if my second map fails i get the error on screen "Exit call failed". I want to fail the map, but the return code is 0 and hence the map completes successfully. Can you let me know how i can modify the below script to fail base don error code. 

Thanks

You would need to force the first map to fail, by wrapping the call to the RUN() function in a VALI()/FAIL() pair.  Example

=RUN("ChildMap.mmc",ECHOIN(1,Input1)+" -OE5")

would change to 

=VALID(RUN("ChildMap.mmc",ECHOIN(1,Input1)+" -OE5"),FAIL("Child map failed to run : "+LASTERRORMSG()))

Only then would your script be able to detect that the call to the Command Server failed.

Thank you.

Thank you Paul.

Can you explain what OE5 includes here in the RUN command. What Input1 carries?

Hi Paul,

I executed the above script and it always fails with error code 30. The error message being "Fail function aborted the map". The user defined error "Child map failed to run" isn't thrown back. Please suggest.

Thanks
