Install new database host and reuse existing ASM database…

My Database-Host was gone (don’t ask why…), but my database files are hosted by ASM (data diskgroup with 3 iSCSI disks), so i was able to install a new Solaris-Host and build up my database server with the existing ASM diskgroup and database in the following way:

Install grid-software with option “software only”

Run the roothas.pl script from Grid_home using the following syntax:

as root user: /app/11.2.0/grid/perl/bin/perl -I /app/11.2.0/grid/perl/lib -I /app/11.2.0/grid/crs/install /app/11.2.0/grid/crs/install/roothas.pl

as oracle user from the grid-home /app/11.2.0/grid/oui> ./runInstaller -updateNodeList ORACLE_HOME=/app/11.2.0/grid -defaultHomeName CLUSTER_NODES= CRS=TRUE

orapwd file=$ORACLE_HOME/dbs/orapw+ASM password=Password123 entries=5

mkdir -p $ORACLE_BASE/admin/+ASM
cd $ORACLE_BASE/admin/+ASM
mkdir bdump
mkdir udump
mkdir cdump
mkdir pfile

init+ASM.ora:
*.asm_power_limit=1
*.diagnostic_dest=’/app/oracle’
*.instance_type=’asm’
*.large_pool_size=12M
*.remote_login_passwordfile=’EXCLUSIVE’

srvctl add listener
srvctl start listener
srvctl add asm -l LISTENER -p $ORACLE_HOME/dbs/init+ASM.ora -d ‘/dev/rdsk/*’

srvctl add database -d DB -o /app/oracle/product/11.2.0/dbhome_1

Oracle, Solaris

Setup Solaris 11.1 / 11.2 for Oracle Database with ASM

# allow root ssh
1) Modify PermitRootLogin to yes in /etc/ssh/sshd_config.
2) Comment out the “CONSOLE=/dev/console” line in /etc/default/login.
3) Remove “type=role” from the root entry in /etc/user_attr.

WinCC OA APEX jQuery mobile smartphone demo…

Apex-Mobile-Demo

Simple mobile smartphone demo build with Oracle APEX connected to WinCC OA (www.etm.at).

It tooks me about 3h… and i had NO experience with APEX!

The map does not work on (my) android smartphone… maybe a known bug: http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-42-known-issues-1863578.html

Connectivity WinCC OA <=> Oracle:

Oracle-DB => PL/SQL => XMLRPC-Calls => WinCC OA (Control)

Currently the connectivity library is very basic, but if i will find some time i will extend it… and you will find it on sourceforge…

if you have a valid Oracle database license APEX is for free! if you don’t have one, you can use Oracle-XE, which you can get for free…. 🙂

Oracle and APEX meets WinCC OA…

With a “few lines” of code Oracle is able to fetch WinCC OA values over XMLRPC webservice – current and history values (WinCC OA RDB-Manager is not needed).

WinCC OA values can be queried with “natural” Oracle SQL Statements

select t.dp, wccoa.dpGet(t.dp||'.int'), wccoa.dpGet(t.dp||'.int:_online.._stime')
from dpnames t where dp like 'Example%'

So, it is also easy to create “WinCC OA” (Web)APEX Applications!

Update C# WinCC Open Architecture Connector

New “C# WinCC Open Architecture Connector” version.

2013.01.01: Added Proxy-Server with client/server TCP/IP connection for dp(Query)Connects and unsolicited data multicasting.

2012.12.23: Added a very simple C# WinForms application which displays two datapoints, waits
for value changes and values can also be set by a button out of the WinForms application.

2012.12.23: Added WaitDataMulti function which performs a dpWaitForValue. Can be used to wait
for a change of value of data points of a taglist.

CommDiagram

Communication can be done directly with XMLRPC or with the included proxy:

  • .net remoting is used for “commands” from the client to the proxy (dpConnect, dpQueryConnect).
  • tcp (xml over tcp) for sending unsolicited data/events from the proxy to the client.

The proxy also acts as a distributor – if clients have the same dp(Query)Connects,
the connects in the control are done once, and the proxy will forward it to the clients.

Added functions for dpConnects without using “Tag” Objects (the Tag objects where created for
mobile clients). Now it is easy to create for example a dpQueryConnect. The callback function
is just a C# delegate:

// create server and client objects
client = new WCCOAClient (ProxyHost, ProxyRemotePort, ProxyClientPort);

// start and connect
client.Start ();
client.Connect ();
client.DpQueryConnectSingle((object s, ArrayList a) => {
WCCOABase.PrintArrayList(a);
}, “SELECT ‘_online.._value’, ‘_online.._stime’ FROM ‘*.**'”);

The proxy (WCCOANetServer.exe) must be started on a server (can, but must not be, the WCCOA Server).

Works fine with MonoTouch and Mono for Android!

WinCC Open Architecture must run the included Ctrl-Script xmlnet_server.ctl
