Useful Hidden URL’s

OT hides many useful URL’s without providing much documentation an effort to codify what is available there

CommandUsageComments
admin.testargshttp://localhost/OTCS/llisapi.dll?func=admin.testargs&helpSA function that can tell you who the user is particularly helpful in debugging authentication.Also can be used to find memory leaks.REMOTE_USER will show up if the webserver has IWA enabled.
admin.threadstatushttp://localhost/OTCS/llisapi.dll?func=admin.threadstatuscan find the status of each running thread also a good way to know if a big web report is running or dead in its tracks 🙂
func=Admin.RebuildAncestors builds both DTreeAncestors and DBrowseAncestors tables
func=Admin.RebuildAncestors&target=DTAbuilds DTreeAncestors only
func=Admin.RebuildAncestors&target=DBAbuilds DBrowseAncestors only
func=attributes.dumpshows a table wise listing of category data structures.Many people do not know that CATS are a Data Structure in a filing system.I added one or two lines in that code to actually print out more info.Many organizations will use this utility to create tables that can be queried by integrators.

Copy This To That

Recently I saw a post in OT Forum that caught my eye https://forums.opentext.com/forums/discussion/comment/935976#Comment_935976 What prompted me to write this is because the OT experts also advised using some other mechanisms (XML WF Extensions and use of WR). Now, normally I like to code as well as any other user in Livelink a.k.a Content Server so why this post is because I remember when OT announced the Item Handler and Item Reference(yes they are different) several years ago I believe when Tammy Jakubowski(now GCI) was the WF Product Manager at OpenText.It was downright confusing but did it work in complicated situation boy it did. So I also asked the same questions why would you need WF Attributes and Form attributes in the workflow because they both do the same thing. But this user kept telling me that Business Workspaces apparently has a WF Step that creates BWS’s and it would only work with WF Attributes and they didn’t want their users to see the WF Interface





I replied with a simple OOB implementation where I used a simple throwaway hardcoded documents inside my WF Attachments map and using two Item Handlers Copied what a user entered in a Form Value to a Category to the throwaway Object and using a second step copied that Category Values onto a WF Attribute.

I later explained to the user in a series of simple screencaps how one would do this as that user needed hand-holding and I find the OT Online Documentation horrendously confusing 🙂 https://knowledge.opentext.com/knowledge/cs.dll?func=ll&objId=77363139&objAction=browse

Mostly this will consist of CWS or SOAP samples.My setup is against a CS16 computer with OTDS but when I test I make sure I can login as ‘Admin’.For ease I write this using the Visual Studio C# express.Note Java WSAPI clients has differing Syntax,my blog has some hints but for the most part it will be adaptable.Note programmers who work in this are encoraged to understand flow of your code into the livelink server see my posts on a proper way to interpret errors you are getting in your program.when time permits I will post a a flow diagram.

What is CWS ?   How do you DEBUG ?  How to look at a SOAP Envelope?
You just have to get the shell from OT for starting java dev. Java data structures are less forgiving in their get/sets than C# as well. Common misconceptions like to write java client livelink has to run in tomcat all that is not true,the server part of livelink can be anything and the webservices hosted either way and you can write .net clients and java clients

A few years back the OT community had a lot of programmers and they all contributed widely to communities.opentext.com .Very thoughtless of OT one fine morning they shutdown the site.Most of the code I wrote for public consumption I had in my personal workspace or google drive.This time I am just going to put them in my google drive.You just have to requests me to see it.Note I will not entertain any requests for obtaining software or consultation.I do this pro bono so I don’t lose touch.

Quickly make a LL System without all the document data

Today I wanted to learn the new Distributed Agent framework in Oscript. To do that I quickly rigged up a VM and had a  oracle export done and imported so it looked like something  with some structure.I looked at the EFS attached it was our DEV machines and it had gigs and gigs worth of data.How do I get categories form this system without copying all that trash so I wrote a query to find all files in the category

.2016-12-06_13-40-50

Notice if I could get just those files needed into my VM it would work so after I put them in Excel and derived a formula I put them in Notepad++.The xCopy with the * creates the hierarchy so that I could copy the small category version files all in all about 1.76 MB very easily.

2016-12-06_13-44-46

so it created the necessary structure (So I don’t have to mess with the table entries)

2016-12-06_13-49-21

after I put them under my new VM’s  file path I can see my categories fine

I am pretty sure I can do this for WF maps,form templates and such like but have to learn DA

Why Oscript solutions are not passĂ©

Over the years in my work with OpenText Livelink I am fortunate to associate myself with like minds and who like me share their code,goodwill and advice selflessly .I cherish and hold their friendship above all professional accolades I have ever got.Recently I had lunch with Ossie Moore  Ossie’s LinkedIn it was very short and I would have loved it to last longer as we could talk shop endlessly.Most of what I write in this has bearing to our lunch and he did steer this post. Ossie  for people who do not know him is quite a character.Let’s say you had a requirement,most of us would probably settle for a pretty decent code either in oscript,lapi as that was the predominant development methods one had at the time.Not Ossie he would probably write our kind of code and before releasing it would have at least two more better implementations,he would have thought about the user coming through the web,the other interfaces LL explorer and so on.That is the difference.

Let’s look at ECM deployments in major organizations.

X Organization has identified a massive unstructured data problem.X has a new manager on the block who has had experience with a technology vendor.Insert <vendorname> here. This is how most ECM deployments happen a lot of people passionate in some technology who would solutionize the deployment to suit the vendor.Most of them are assisted by Gartner, Forrester those kinds .I started working in OT technology before these rating companies came up with a barometer of wants so I am going to continue with my cynicism.

So after X Organization will roll out a OOB approach ,people are brought in.Naturally if the product is user friendly and easy its use will grow.Simple things like user activity,data growth etc are good ways to identify its usefulness.Now most people would want to send the link of the objects hoping that it won’t break on re-organizing the structure or re parenting as most of document work revolves around.So you may want to invest on something that people have put thought on like a GUID based system(Livelink, DCTM).Frankly I know only Livelink and DCTM very little. I hate Sharepoint (we call it $carepoint) with a passion because the smallest of things are so difficult to get  done.Good UI all the world has gone for it anything complex you have to buy or build with an array of .net developers different frameworks the works.It also could be that I have only been programming in that and spending time in LL so over the years the idiosyncracies of builder,CSIDE none of these matter to me now because Oscript really has not changed every much.Oscript is just a huge possibilities language. One of my mentors very famous in OT circles John Simon would joke like this.You have a problem you try solving in Oscript.You will spend about 3 to 4 days on it later to find out that what you need is totally available,no need to kludge just poor documentation that is all.

So if you were eager to get into using livelink to its full extent do these things

  1. Challenge a OT person or a OT solution marketer to what they are offering you. Challenge them extremely hard if it is offered at $$$ a user or so.That is how they make their money on licenses.
  2. Challenge if the pitch is towards Oscript is bad that spoils your chances of upgrade.There’s an element of truth in that.I have seen people hacking their way into core code,weblingo such no nos that shows inexperience and desperation. Oscript is not understanding the creation of a request handler,webnodeaction or eventscripting it is an all round knowledge of the product the passion about the product.You can immediately tell if the programmer knows anything because if they start saying about new subtypes you may want to ask them what prompted them to create a subtype, because many times those people have access to the oscript tutorials and the “Hello World” of oscript introduces them to that.You really want a Oscripter who will follow what OT advises them of doing in that case it is very rarely  a bad fit.
  3. Challenge if the pitched solution ends up working only in the webgui what about EC,what about SOAP,what about REST,what about Search

Oscript has years to go if the LL solution is still being used by customers.It can be learned to work wonders for you.The other aspect and full credit to Ossie here is LL software is the most open product much more open than opensource a oscripter can see the entire internals of it so people like me,John,Ossie all have found bugs and we all engage the good OT developers on our finds.Most senior and passionate oscripters continue to do so.There ‘s so much openness and welcoming in the OT programming community,people like David Templeton ,Kyle  Swidrowich and a countless amount of good people who have been striving to keep this open and getting communities to try it out for a better product.They have helped me and a lot of others and you can also get in into the action.

You just need the drive and passion to master LL that is all it takes.Well that maybe true for any technology 🙂

AddressBook

Today I just chanced to see a post where somebody could not get the famous AddressBook module working.This module was part of the Oscript documentation and is usually introducing the user to the various concepts livelink programming entails.Like a “Hello World” for Oscript :).I thought of helping the person and the person had deleted the post.which was originally here  He later removed it because many people do not want to appear wrong.However there is no harm in asking or being wrong.failedaddressbook

 

Anyways I had done this for another friend so releasing into public domain here….

I did not fix many problems in the module so it is a challenge to the person doing it that is how I learned:)
