RE: array_user.conf row creation

Thanks Robert.
Actually that problem is resolved. I was not allocating memory properly.

Thanks Robert.
I have implemented my Sample MIB and its up and running now.
The problem is when I query the Table its giving "Error in Packet", "No
such Name in this MIB. I though it's the problem with index and tried
with some changes there, but it dint help.

When I am querying the agent, proper index is appended which I used for
creating the table row. Also I am suspecting my register function
whether it is successful or not. (netsnmp_table_container_register is
returning 0).

Snippet from my code is attached below.

Creation of row <<start>>
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3 D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D
netsnmp_index index;
xxxTable_context *context;
oid tmp_oid[256];

initialize_table_xxxTable();

/* set temp oid for new row */
tmp_oid[ 0 ] =3D 1;

/* set temp index */
index.oids =3D tmp_oid;
index.len =3D 1;

/* create row */

context =3D cpqHoFileSysTable_create_row(&index);
context->val1 =3D 100;

Creation of row <<END>>

Waiting for you reply...
Regards,
Geo

There are two ways to do this. One is to completely flush the cache each
time,
and reload it from scratch. The other is to search the cache for exiting
rows
to update/add/remove.

The first is fairly simple. use CONTAINER_FOR_EACH to go through and
free each
row, then CONTAINER_CLEAR, followed by inserting all rows again.

The second is a little more complicated, but required if you want to
keep some
non-cache data in the row. For an example, see the ifTable cache_load in

mibgroup/if-mib/ifTable/ifTable_data_access.c.

yep, that would work.

Since the agent is single threaded, and alarms don't run while requests
are
being processed, it shouldn't be an issue.
