Re: multiple Sub-agents managing the same table

Hi,

Thanks Dave. What I've done now is:

{

// Declare the top Oid for my table
oid genServerTableOid[] =
    { 1, 3, 6, 1, 4, 1, 99999, 10000, 1, 1 };

size_t genServerTableOidLen = OID_LENGTH(genServerTableOid);

// Get an unique index from the master agent
u_long allocatedIndex = register_int_index(genServerTableOid, 
genServerTableOidLen, ANY_INTEGER_INDEX);

// Strangely, it has to begin with the index 2... @todo
while ( allocatedIndex <= 1 && allocatedIndex > 0 )
{
     allocatedIndex = register_int_index(genServerTableOid, 
genServerTableOidLen, ANY_INTEGER_INDEX);
}

// Define the oid of the first column from the index returned
oid genServerAllocatedOid[] =
    { 1, 3, 6, 1, 4, 1, 99999, 10000, 1, 1, allocatedIndex };
size_t genServerAllocatedOidLen = OID_LENGTH(genServerAllocatedOid);

// Define the structure of the table
...

// Set the range_subid to the first column of the row
handlerServerTable->range_subid = genServerAllocatedOid;

// set the range_ubound ???
handlerServerTable->range_ubound = allocatedIndex;

}

If I test this with App1 (I launch my application several times), this 
works.

But with App2, this is not working, probably because of the range_ubound 
(I'm a little bit confused with that parameter).

If I understand you, I should set range_ubound to 5 (I have five columns in 
my row) ? I'm not really sure...
