15-Aug-16). How do I pass an exit code from sqlcmd? (CS-SQLServer)

How do I pass an exit code from sqlcmd to the batch file that is calling it? It turned out this is not a simple issue. The research will take you into understanding the sqlcmd.exe. Understanding transact-sql. Knowing how the options provided by sqlcmd.exe are confusing and unspecific. See how one TINY opening is left with raiserror function and you have to pretty much go for the precise bulls eye and a very specific parameters supplied to the raiserror to make this work.

How do I schedule a backup database program on windows servers? I have SQL Server 2008 Express on my azure server. It doesn't have any tasking or scheduling tools as it is an express version. Recommendation is to write a SQL server script and invoke it through sqlcmd.exe. Then have a windows scheduler schedule it at regular intervals. By the end of this research I will know how to schedule full backups and also differential backups using command line tools.

10-Aug-16). Folders, Tags: And now implement Display Contexts (Aspire Notes)

Folders and tags are typically used to classify documents. This classification can then be used when displaying that document. Sometimes a document may want to dictate how it wants to be displayed: for example to show what are the related documents.

The dependent documents may not be aware of the main document that wants to pull them together. However when they are displayed in the context of the requested document they honor that context and show the links coming from the main document.

It may be possible to do this with dedicated tags or folders for that matter. (Something to think further in the design)

How to see files that are newer than a certain date


xcopy .\*.java c:\temp /s /L /D:11-22-2007

Show java files that are more recent than Nov 22nd, 2007 in the current directory and sub directores.

/s indicates to span sub directories

/L is to display only

you need to have a target directoty. use this with caution. For some reason if you omit the /L you will end up copying.

3-Aug-16). On Docker (Enterprise Integration)

Docker is an OS (especially Linux at the moment) level facility/technology that can build OS images dedicated all the way to the application level in multiple layers. Developers will build docker application images instead of application packages where by the application images are stand alone and can run on any hardware on *any* OS. The images are layered and can be shared publicly or privately. Docker provides the verbs and scripts necessary to build, deploy, and monitor application images running in containers on a native OS. Docker containers are significantly lightweight compared to virtual machines making distributed, scalable, multi-tenanted computing engines in the cloud effective and efficient.

Kubernetes establishes robust declarative primitives for maintaining the desired state requested by the user. We see these primitives as the main value added by Kubernetes. Self-healing mechanisms, such as auto-restarting, re-scheduling, and replicating containers require active controllers, not just imperative orchestration.

3-Aug-16). 5049 Poem: Solitude by Alexander Pope (Humanities Current)

HAPPY the man, whose wish and care	
A few paternal acres bound,	
Content to breathe his native air	
            In his own ground.	
 
Whose herds with milk, whose fields with bread,	       
Whose flocks supply him with attire;	
Whose trees in summer yield him shade,	
            In winter fire.	
 
Blest, who can unconcern'dly find	
Hours, days, and years, slide soft away	       
In health of body, peace of mind,	
            Quiet by day.	
 
Sound sleep by night; study and ease	
Together mix'd, sweet recreation,	
And innocence, which most does please	        
            With meditation.	
 
Thus let me live, unseen, unknown;	
Thus unlamented let me die;	
Steal from the world, and not a stone	
            Tell where I lie.
