BTW this is kind of a cookery show kind where they put the main course in the oven and take another finished one .I did not accomplish any of this in one day it took a lot of homework and trial runs.I read the case studies by the great Rob Coutts many times over.
For sanity we decided to use a new box for CS10.5
Created a CS10.5 system added all the modules that we needed and connected to a dummy database and dummy EFS. Just for kicks we added some that did not exist in 971 like classifications and recman(forward thinking).Rudimentary checks to ascertain base functionality.Note all hot fixes ,patches relevant were also put.
Cloned this server to 3 others for Front Ends and Agents.Just architectural things as after the LL installer creates the services just copy the OTHOME over ,give it distinct names etc.Sometimes if your copies are done with IIS and or any of livelink services running sometime corrupt dll copies end up so make sure you follow proper protocol.In most cases you do not need to run the optional modules installer on your 2nd to n CS servers.Most livelink needed dll’s oscript code will try to push it to windows systems folders on startup every time.
Saved this and copied it as backups.
It is worth verifying the DB type requirements for 10.5 for e,g your 971 DB might have been 11.2.0,2 but Cs10.5 need 18.104.22.168.these are database chores that your DBA should know. Always give lots of oracle memory like SGA etc .OT has a tech article on how it is to be done.
Connected the binary to the prepped up 971 database.one of the first screens was the 971 box for Admin server,changed it to the new box .
Wanted re-starts it is a good sign.One thing I do is since I know the DB Upgrade is done by a single thread I made the threads 8 on it.If you have lots of threads they indirectly add to the Oracle load.I also do my upgrades with debug=2 and wantlogs=true.It is almost impossible to live without BareTail or a good ASCII Editor.
The other threads on it will just produce a warning message that the “upgrade is in progress”.
Once the upgrade starts you should see the thread<nn>.out file issue oscript commands and its corresponding connect<nn>.out doing DB work.Your heart will rejoice if you have them on baretail 🙂 In my case a core upgrade will move my 971 schema(6.0.8) to CS10.5 (6.2.58).If it does that it is a successful upgrade. Times will vary depending on data and content and horsepower of your DB.Do not try to run arithmetic on the numbers does not mean continuous although looking at the db upgrade log one can see the steps.The places it breaks clues OT and even if you know Oscript you can chase a lot f them.In my case it was let’s say a very smooth upgrade.
Since we had optional modules after the core upgrade all optional module schemas were introduced or upgraded.You should see it in bold letters in the pre upgrade page. “Your Content Server schema will Upgrade from <nn> to <nn>”.Classifications module will be introduced,Recman would be introduced(New things), ADN will upgrade from <nn> to <nn> .BTW I had to downgrade A D N to a lower one because the latest and greatest won’t cleanly co operate with the upgrade.You will not notice the difficulty if your database is new.
The reason why OT says to upgrade OPT modules after core upgrade is it is easier for them to pinpoint the failure.
The way livelink code works every time you re-start is it will read Opentext.ini and one of the first modules that loads is the DBWIZAPI .It will first try to ascertain whether core schema is what the binary says its is otherwise it will force a DB Upgrade.Before releasing the software to listen to request on 2099(suggested default),it will enumerate the module section ini to the schema section INI. So if one box had a schema aware module such as form and its INI said 2.0.4 and this box’s form module said 2.0.3 it will trigger the familiar error “You have blah blah in database but blah blah module is lower/higher”.That is the whole reason why experienced people and nowadays OT says get one server(Anchor) done correctly and clone that on other boxes.So whether you install opt modules after or before livelink code always checks this every time you re-start.
The Admin Service left running on any box is no problem.It contains java code to talk to the search server.Also memcached is dependent on Admin Service.I don’t really know what cluster agent does but it is OT’s answer to smart patching.Once you resister a Admin server to the database that is when the box can be used for certain things like augmenting search.
We had to create a search as advised by OT so that items would come out indexed faster.I am always amazed at the search code but unfortunately one cannot see it completely as Oscript just talks to the java code.Perhaps if I had time and code was de compilable( I seriously doubt it,I have a feeling java is talking to C++ compiled code internally,how else would it scale so well).To have people always complain about search ….
I installed all our custom modules created clones of this and called it many different roles and we were pleasantly done
The rest was mainly releasing it to customers to test have their suggestions and voila…
Recently I was tasked with upgrading our systems from its initial version to two times jump so 971 to 10.5.I will chronicle my experiences here. Perhaps provide a structure.I also want to quell some myths about the whole process just to make sure you can do this logically and correctly.
First create a draft plan,in my draft plan I included this.I would need at least one VM that can house or Production 971 Binaries,a clone of the database and a clone of the EFS.If one had been storing items in perhaps Archive Server one should have a playing copy of that also. An OTAS based livelink upgrade can pose its challenges if not done correctly but it is no different than a EFS if you do it wrong you can write test data into your productive store 🙂 This involves talking to other people like DBA’s and Storage folks as a heavily used LL system can have tons and tons of data.You will most likely encounter the after effects of long time use,different administrators and their styles etc.So after a few failed attempts I understood why OT says a DB5 verification is very important.The Verification basically runs single threaded and will try to pinpoint anomalies in the database.Most likely it will pinpoint content loss such as bulk imports etc without actual version files et al .In my case the database had wrong pointers,duplicate dataid’s (wow),removed KUAf Id’s(somebody had fun with a oracle tool).So after going back and forth between OT and us I just thought like this and created a program(oscript) to check important structures.I list 3,your mileage will vary but essentially I grabbed all categories ,form templates and wf map structures.None of these checks happen in DB5 it just looks for existence.In hilarious cases I uncovered a category data structure mysteriously would turn up as a drawing PDF.One could argue that the users would have noticed, so this was an old category that nobody noticed.You don’t have to do this but each of those anomalies would prevent a upgrade and it is back and forth with OT support so I did it just to get some time advantage.
The second thing was I had to get all the optional modules and our system is no different from any other system a lot of optional modules some inserting schema some not.
The third thing was our systems were customized with Oscript to provide enhanced user experience as well as awesome home written modules that takes the tedium of long running things like category upgrades,permission pushes et al a very intelligent add on to the OI module that people can use generically to upload their data like that.So our team sat down and thought of what we could retire and what we should re-code,refactor so many of them were thrown out .Many useful ones we kept.We particularly liked the Distributed Agent framework,ours is very similar to that but if time comes and there is an appetite we would code it for that.
About the re-coding effort here’s the clunker,we were to use CSIDE .Naturally all of my team are hard core Builder aficionados and boy that was a journey.I probably think we were the first org to do something with CSIDE so naturally I gave them a lot of screenshots and dumps and OT dev was very receptive.In extremely tight time constraints we developed parallel modules in 97 1 and 10 and just just sucked them up for our SRC code maintaining thing called TFS. We also learned how to work parallel on oscript but not being a code churning house our code is not that complicated so if I was working on a module somebody else was working on another as well.
So the environment prepared was
971 VM with the same Oracle client and the same DB type of clone.
I removed Prod EFS and Prod Admin server info from clone.
We decided to rebuild search index as nobody had any clue whether it was good and it was eons before new search technology.
A base install of LL was done and the working 971 binary copy from prod was put as an overlay.Now many starting out people do not know this technique where you can get a copy of your prod binary replete with patches et al into a playing system.BTW this is what you hear as the “Parallel Upgrade” approach .Its database connection was redefined .In very olden times when there was no differentiation between 32 and 62 bits and VM’s were not popular and cheap, it was possible to use the existing boxes and run the upgrade.This was the “Update an Instance” method.This is largely vestigial at this time and very error prone not to say you would have a real hard time going back to the working version 🙂
All old 971 custom modules were removed so this database had only knowledge of OT software core and optional.
Did my health check I said earlier like look at cats,form templates and wf maps,removed any that would hamper a upgrade.
At this point one can take this to a CS10.5 binary and start the upgrade.That is my next article.
BTW- I am not a novice when it comes to Upgrades I started using livelink software in 1999 and has worked in version 8.1.5 so I pretty much know the heartbeat of an upgrade and gets pleasure in challenges and how one methodically removes the challenges.Do not try an upgrade if you have not dry run the procedure without fail a couple of times.In most cases the upgrade can be done timely the planning can take weeks,if not months.
