Question Usage of NOHUP - How to keep the child process running even if I close the Server connection
Hi. !

When I use the 'NOHUP' along with the '&', the process will be running in the background. Even when I attempt to close (Meaning 'EXIT') the session (say PUTTY in this case), it wont exit unless the process is completed.

But, say when I forcefully terminate the session (SHUT DOWN the machine). In this case, all the child processes will be terminated and the parent process will continue.

What I need is that, even though I forcefully terminate the session, I need both the CHILD and PARENT processes to run and complete successfully.

Exact Scenario: I'm running a UNIX (Parent) shell which in turn calls an ORACLE (Child) session. When I run it with ‘NOHUP' and ‘&' and terminate the session forcefully, the ORACLE session will terminate and will give to control to the UNIX session, which will run the remaining UNIX operation.
I don't want this to happen. Even though I forcefully terminate the session, I need both the ORACLE (Child) and UNIX (parent) session to run and complete normally.

Kindly advice.

Thanks,
Barani

mdbfontsize

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME

       mdbFontSize - Font Size

DESCRIPTION

       In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
       bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
       about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.

       FONT-SIZE-ADJUSTMENT ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ADJUST-RATIO ::= INTEGER

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:

	   ((devanagari-cdac) 150)

       instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
       'devanagari-cdac'.
