Re: [Wrapper-user] configuring mulitple processes

[Donal M. <dom...@ya...>]

Hi,=0A=0AThanks for the response Leif. I stumbled across the #include optio=
n shortly after I sent the message below.=0A=0ARegarding the way the 4 proc=
esses are set up, all the .conf files *are* in the same directory. I notice=
d that the .sh script (on Solaris) has the .conf file path and APP_NAME wit=
hin the script itself, so I've modified this scripts to accept these as par=
ameters.=0A=0AIn the .conf files for the processes themselves (rather than =
in the common .conf file that they #include), I've specified a different wr=
apper log file for each process. If I also add a unique wrapper.java.pidfil=
e property for each process, then are there any other changes I need to mak=
e in order to safely execute all 4 processes simultaneously?=0A=0ABTW, I ex=
pect you already know this, but the "su" command in the script does not wor=
k on Solaris as it does not accept a "-m" option. I'll look into a workarou=
nd for this tomorrow and can let you know what I come up with if you're int=
erested?=0A=0AThanks for providing such a great tool!=0A- Donal=0A=0A----- =
