Re: Multiple patterns/ .sub files for the same .db file

[Tito Körner <tito.koerner@gmail.com>]

Hi everyone,

Emmanuel's solution works for me. Thanks for that!

And to explain things a little more: I have records redaing and setting voltage values - therefor i need "pattern {PROTO, P, BOXNO, LEVELNO, CHANNELNO, ELEMENTNO}" and then I have records reading and setting some internal values of the hv boxes and fo these I need the other pattern. I thought I could use a single .db file containing all the records and one .sub file with the patterns but obviously epics doesn't like different patterns in one .db file.

But by splitting up the records in 2 .db files (one related to everything concerning high voltage setting, and the other taking care of internal values it works out fine)!

Thanks again for the help!

Regards,

Tito

In your template file, all the parameters need to be defined.
I believe you need to break down your db file in 2 templates.
You substitution file to call in dbLoadTemplate can look like
file "template1.dbt"

{
    pattern {PROTO, P, BOXNO, LEVELNO, CHANNELNO, ELEMENTNO}
        {hvtest.proto, HV, 19, 0, 0, 0}
        {hvtest.proto, HV, 19, 0, 1, 1}
}

file "template2.dbt"

{
   pattern {EELO, EEUP}
        {dhcp, DHCP}
        {ip, IP}
}

template1.dbt includes ONLY the records that use the first set of parameters
template2.dbt includes ONLY the records that use the second set of params.

Hello,

I have .sub file looking like this:

file "hvtest.db"
{
    pattern {PROTO, P, BOXNO, LEVELNO, CHANNELNO, ELEMENTNO}
        {hvtest.proto, HV, 19, 0, 0, 0}
        {hvtest.proto, HV, 19, 0, 1, 1}
}

Now I would need another pattern in the same .db file looking like this:

file "hvtest.db"
{
   pattern {EELO, EEUP}
        {dhcp, DHCP}
        {ip, IP}
}

I tried two dbLoadTemplate - lines in my .cmd file

dbLoadTemplate "a.sub"

dbLoadTemplate "b.sub"

but I then got Error messages saying the substitutions from the first file are undefined. I also tried to put both patterns in one file (I found examples with different patterns for different .db files). But then again I get error messages saying the substitutions are undefined. When I directly append the second pattern after the first, I get a syntax error message. So how can this be done?

Tito
