I think guide is wrong. Don't have access to oracle right now so can't check, but it should be like this (if environment is set correctly and "sqlplus Netxms/mpsdev@MPSDEV1" connects successfully):

Database = id=mpsdev1;driver=oracle.ddr;server=MPSDEV1;login=Netxms;Password=mpsdev

or you can use instant client connection string without tnsnames:

Database = id=mpsdev1;driver=oracle.ddr;server=//lltcdevoda1-scan:1521/mpsdev1;login=Netxms;Password=mpsdev

or you can even use full connection string there (haven't tried that, but should work as well):
Database = id=mpsdev1;driver=oracle.ddr;server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=lltcdevoda1-scan)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=mpsdev1)));login=Netxms;Password=mpsdev

I've fixed that, now snapshots should work as well

Script, which generate this header require git repo, not a snapshot. It's a bug.
However, if you clone repo instead of using snapshot – it will work.
Repository url for clone is https://git.netxms.org/public/netxms.git

P.S. don't forget to switch branch to "develop" (git checkout develop)

Use ping subagent for that: http://netxms.readthedocs.org/projects/admin/en/latest/common-tasks.html?highlight=ping#icmp-ping

I removed big chunks of the text (unrelated to MIB definition) from top and bottom of the files.

You need to create new shared library with custom implementation of HelpDeskLink class. I'm afraid we don't have any documentation on developing modules, but it's pretty much straight forward.

Here is interface definition: https://git.netxms.org/public/netxms.git/blob/refs/heads/develop:/src/server/include/hdlink.h?js=1

You can check existing JIRA implementation:
https://git.netxms.org/public/netxms.git/blob/refs/heads/develop:/src/server/hdlink/jira/jira.cpp?js=1
https://git.netxms.org/public/netxms.git/blob/refs/heads/develop:/src/server/hdlink/jira/jira.h?js=1

You can try to use netsvc subagent instead (which is libcurl based) and set http_proxy variable before starting agent. It's a bit ugly, but should work.
Details on netsvc: https://www.netxms.org/forum/configuration/servicecheck-http-2780/msg12143/#msg12143
A bit details on libcurl proxy support: http://curl.haxx.se/libcurl/c/CURLOPT_PROXY.html

Another option is to use configure external parameter using curl / wget:ExternalParameter=CheckHTTPWithProxy:curl -o /dev/null -s -x http://proxyhost:3128 $1; echo $?

Then use it like this:nxget localhost 'CheckHTTPWithProxy(https://www.google.com/)'

1) Event log ("event_log" table) have it's own retention time and it's completely independent from DCI history.
Retention time is controlled by server parameter "EventLogRetentionTime". Default value is 90 days.

2) Two options: create object tool with type "Download" pointing to server's log (enabled "follow changed", if desired), or enabled filemgr subagent on the agent and use file manager functionality for that.

Can you share some sample database? It will be quite easy to change your code into migration tool, but I need some data to test is on.

This issue is already fixed in trunk.

Looks like network configuration issue. Check that server is reachable (4701/TCP) from your workstation.

Try attached script.

Yes, it's possible to do with nxshell. Some examples:

find by mac:
import sys
mac = sys.argv[1].upper()

for node in [o for o in s.getAllObjects() if isinstance(o, objects.Node)]:
    interfaces = node.getAllChilds(objects.GenericObject.OBJECT_INTERFACE)
    for interface in interfaces:
        if mac in interface.getMacAddress().toString().upper():
            print "%s(%d) - %s - %s" % (node.getObjectName(),
                                        node.getObjectId(),
                                        interface.getMacAddress(),
                                        interface.getIpAddressListAsString())

find by ip:
import sys
ip = sys.argv[1]

for node in [o for o in s.getAllObjects() if isinstance(o, objects.Node)]:
    interfaces = node.getAllChilds(objects.GenericObject.OBJECT_INTERFACE)
    for interface in interfaces:
        for interface_ip in interface.getIpAddressList():
            if ip in interface_ip.toString():
                print "%s(%d) - %s - %s" % (node.getObjectName(),
                                            node.getObjectId(),
                                            interface.getMacAddress(),
                                            interface.getIpAddressListAsString())

Sample session:
~/Development/netxms/src/java/nxshell/target (develop|...)% java -Dnetxms.server=127.0.0.1 -Dnetxms.login=admin -Dnetxms.password=netxms -jar nxshell-2.0-RC2.jar find_by_mac.py B2:00:1C:15:BC:E0
AirAlk.local(100) - B2:00:1C:15:BC:E0 - 0.0.0.0/0
~/Development/netxms/src/java/nxshell/target (develop|...)% java -Dnetxms.server=127.0.0.1 -Dnetxms.login=admin -Dnetxms.password=netxms -jar nxshell-2.0-RC2.jar find_by_ip.py 127
AirAlk.local(100) - 00:00:00:00:00:00 - 127.0.0.1/8

Works for me.
Make sure that you updating correct file – we've changed filesytem layout a bit, now it's in $prefix/var/lib/netxms.
Start server with debug level 1 or higher and search for this line in log:
[20-Nov-2015 23:45:12.379] [DEBUG] Data directory set to /opt/netxms/var/lib/netxms
