Overall this looks good. I encountered a couple of small rough edges from the ibm-base layer, which can be addressed there. But I did notice that the ibm-db2.client.sshconfigured state is not set per-consumer; once any consumer sends SSH keys, all consumers will assume that keys have been sent, and once any one consumer departs, all consumers will be blocked even if they previously sent SSH keys. I don't know if that was intended, but it seems like that state should be set by the interface layer instead, such as in the dismiss() method.

Hi Cory,
 I have done the changes as per your suggestions. Please review once and let me know.

Thanks,
 Suchitra

Hi Suchitra - to be compatible with recent changes in the db2 interface layer [0], I updated layer-ibm-db2 source so it uses the 'db.connected' state instead of 'db.available'. There is no need to have both states in the interface, so I removed references to the undocumented 'available' state.

The resultant ibm-db2 charms seems ok to me, but I would like you to verify this still works as expected for you. A charm based on these changes is available here:

https://jujucharms.com/u/ibmcharmers/ibm-db2/trusty/35

And can be deployed with:

juju deploy cs:~ibmcharmers/trusty/ibm-db2-35

Please let me know if this works as expected for you. If all is ok, we'll promulgate v35. Thanks!!

A diff of the changes from my comment above can be found here:

http://bazaar.launchpad.net/~ibmcharmers/charms/trusty/layer-ibm-db2/trunk/revision/10

Apologies for including lint fixes there; you can find relevant changes by searching for 'db.connected' in that diff.

[Kevin W Monroe (kwmonroe)]

I made a mistake in the ssh_key handler in the interface, which has now been fixed. A new version of ibm-db2 for test is available here:

juju deploy cs:~ibmcharmers/trusty/ibm-db2-36

[Suchitra Venugopal (suchvenu)]

Charm is tested with the changes. Few minor changes are done to handle the states properly.

DB2 stopping the apps before db2stop

[Kevin W Monroe (kwmonroe)]

Hi Suchitra, I made quite a few tweaks to the layered source:

http://bazaar.launchpad.net/~ibmcharmers/charms/trusty/layer-ibm-db2/trunk/revision/20?compare_revid=15

Some are cosmetic, others are bash-ism tweaks (like comparing strings with == and integers with -eq). The most significant, however, is in the password handling of db2 users.

I didn't realize before that the db2inst1, dasusr1, db2fenc1, and the users for related units all had default passwords. This isn't acceptable for applications providing network services, so I updated this charm to use the 'pwgen' utility to create random passwords for these users.

Have a look at the above diff, which is available for deployment at:

cs:~ibmcharmers/trusty/ibm-db2-39

If you're ok with these changes, we can (finally) promulgate v39 :)

Thanks!
-Kevin

[Kevin W Monroe (kwmonroe)]

There was a bug in the leadership layer [0] that would cause the config.set.x states to be reset after the 'leader-elected' hook was run. This caused the db2 charm to report blocked even after installation because it thought license.accepted was no longer set.

This has been fixed in cs:~ibmcharmers/trusty/ibm-db2-41

We'll need the MP in [0] to be merged before officially promoting v41. Hopefully that will happen in the next few hours.

[Suchitra Venugopal (suchvenu)]

 I just removed the 2 functions you added for missing license and curl config , to check whether everything else is working fine.

1. DB2 gets installed but shows the state as

ibm-db2:

    exposed: false
    service-status:

      message: Installing binutils,curl,pwgen,tar

I revert back the change you did for remove_sshkeys() function and its working fine.
What was the reason for this change ? I tried testing with 2 consumers and it looks fine for me, while removing the relation between DB2 and this consumer.

[Suchitra Venugopal (suchvenu)]

Done the following changes with combined effort from Kevin and myself.

1. Issue related to unordered status fixed.
2. SSH key issue - reverted back the code changes related to this.
3. Updated README file with DB2 limitations

new build of layered db2 charm (source lives in lp:~ibmcharmers/charms/trusty/layer-ibm-db2/trunk)

[Kevin W Monroe (kwmonroe)]

This has been a long time coming, but it looks good :) The layered ibm-db2 charm is now promulgated (https://jujucharms.com/ibm-db2/) and can be deployed with:

juju deploy ibm-db2

Thanks for the patience and work to get this charm into a recommended state!

+# Overview
+
+This interface layer handles the communication between IBM DB2 and Consumer
+charms. The provider end of this interface provides the IBM DB2 service. The
+consumer part requires the existence of a provider to function.
+
+## Usage
+
+### Provides
+
+This interface layer will set the following states, as appropriate:
+
+- `{relation_name}.connected`: The relation is established, but IBM DB2 may not
+yet have provided any connection or service information.
+
+- `{relation_name}.sshconfigured`: A consumer ssh key has been added to the
+IBM DB2 `authorized_keys` file.
+
+- `{relation_name}.ready`: IBM DB2 has established relation with the consumer
+charm and the SSH key has been exchanged. DB2 has provided its connection
+string information, and is ready to accept requests from the consumer.
+
+- `{relation_name}.departed`: The relation has been removed. Any cleanup
+related to the consumer charm should happen now on the IBM DB2 charm since the
+consumer is going away.
+
+
+### Requires
+
+Consumers like WAS, Mobile First Server, etc require this interface to connect
+to IBM DB2. This interface layer will set the following states, as appropriate:
+
+- `{relation_name}.connected`: The consumer charm has been related to IBM DB2.
+At this point, the consumer charm sends the SSH key to IBM DB2 charm.
+
+    For example, the consumer charm can send the ssh key to IBM DB2 charm as follows:
+
+    ```
+    @when 'db.connected'
+    @when_not 'db.sshconfigured'
+    function configure_sshkeys_dbs() {
+        SSH_PATH=/root/.ssh
+        if [ ! -f  $SSH_PATH/id_rsa.pub ]; then
+                juju-log "Setting up SSH keys."
+                ssh-keygen -t rsa -f $SSH_PATH/id_rsa -N ''
+        fi
+        key="`cat $SSH_PATH/id_rsa.pub`"
+        relation_call --state=db.connected set_ssh_keys "$key" || true
+    }
+    ```
+
+-  `{relation_name}.ready`: IBM DB2 is ready to send connection information.
+The consumer charm can access the IBM DB2 details from the interface using the
+following methods:
+
+   - get_db2_hostname() - host name of IBM DB2
+   - get_db2_port() - port number of IBM DB2
+   - get_db2_path() - the install location of IBM DB2
+   - get_dbusername() - User name created for the consumer service to connect to DB2
+   - get_dbuserpw() - Password for connecting to DB2
+   - get_db2_instance_name() - Instance name created for the consumer service
+
+
+- `{relation_name}.departed`: The relation has been removed. Any cleanup
+related to IBM DB2 should happen now on the consumer charm since IBM DB2 is
+going away.

+unpacked or non-standard modules imported (including the charms.reactive
+framework itself).
+
+Operators needing to use this functionality may branch a charm and
+create an exec.d directory in it. The exec.d directory in turn contains
+one or more subdirectories, each of which contains an executable called
+charm-pre-install and any other required resources. The charm-pre-install
+executables are run, and if successful, state saved so they will not be
+run again.
+
+    $CHARM_DIR/exec.d/mynamespace/charm-pre-install
+
+An alternative to branching a charm is to compose a new charm that contains
+the exec.d directory, using the original charm as a layer,
+
+A charm author could also abuse this mechanism to modify the charm
+environment in unusual ways, but for most purposes it is saner to use
+charmhelpers.core.hookenv.atstart().
