WWI Issues: HELP

[Former Member]

Hello all together,

we have been receiving some issues lately  with our WWI.

we just did an SERC update 15-2-  and havent done an update in regular bases.

Now the issue now is that our WWI Server is being a jerk.  It stops, but no error is given.

1.  The Services for Windows are there.

2. the Registration is not.

But by checking

CGSADM- Shows no Errors

CG5Z- Shows assigned or Completed. no inccorect.

SM37-

it hangs or gets stuck, and by coincident we see it and then restart the Server or Trigger in CGSADM the Server.

We get no Information to any Errors, why things break, hang up or stops.

We do not have the Patch 42 yet.

Anyone can give a hunch of an idea where to start looking?

I'd give more Information but I dont have anything else to give.

Or is it Casper spooking in WWI again?

Thanks

Anna

ok now the last Crash was around 12:38,  in cg50 the past days were not any reports generated with Errors,  today as i just checked- is a French Report not generated and looked at the Report and found a Phrase error- checked France and no Translation in any language for this Phrase.  so DUH of course it cant be released at end because no French text for this Phrase.

It cant be this easy and that this is issue? I will see what happens over the Weekend and check each Report being generated with Warnings and , if i find anymore such Errors. because if so then sweet, easy peasy.

Ive been working with WWI now for 7 yrs now and with all ist bugs and twerks and all i have grown with, I still like wwi. Ist OWN WORLD!

Let me see what happens till monday- and dig then more deeper.

Dear Anna

if there is no report in "error" status in CG50: can you please check CVD1. Is there any shipment done ?? Normally the WWI processes only "crashs" if there is something to "process".

If there is no traffic in most cases nothing happens on WWI side.

In one of the many WWI threads it has been  noted that there is some "automatic" reboot done on WWI side;but in this case the process should do all "automatic" and "guarantee" that after the "reboot" the WWi server is up and running normal.

PS: please check

Dear Anna

any update here?

Hello Christoph,

we have 3 WWI Servers, and a fourth in process.  for each system

Yesterday, as I cam back from my vacation,  after a restart was done in the am before I arrived, through SAP bases, it was running all day very well.  Then around6-7 ish pm, it got stuck again and bases did a restart this morning again. but no notification was received about a break down or stop or so.  We control, my colleague and I every mornin, by Monitoring.

she again did a restart, I come to work, and it is running smooth again.  *maybe my WWI Server Baby misses me* haha joke by side. We have a love hate relationship.

1. we activated the logging.  T5 and nothing helpful, and the T7 is pointless because there the was was achieved and completed logs are written.

we also in the IMG activity Specify environmental Parameters.

As i just was informed:  yesterday around 17 it got stuck, and then again now around 9:38, and before then around 18- no pattern to be seen. alwasys at different times.

Doesnt mater if a big Report is being generated or a small one, or if for France Report or another Country.  it chooses wildly when it hangs up.

anyways- i'll take a look and get back to discussion if more question arise.

WWI_GENSERVER_ERROR_MAIL

WWI_GENSERVER_SYN_ANCHOR

WWI_GENSERVER_SYN_DEST

usw.   for the Parameters that were checked, and activated.

the error mail only sends email when we Trigger a Server restart but not when something happens by itself.

that part didnt get copied.

Dear Anna

a.) you have three servers

b.) I am not sure regarding your explanation. Did you now "restart" all the three servers?

This is an idea only for you to may be look deeper.

Based on your explanation: we can "exclude" in my opnion the "MSDS/SDS" dispatch scenario (to crash the WWi services).

It seems to be that during the generation of the reports some (all ?) servers are "killed". This is my story:

You have three servers. If something happens on server 1 we still have  2 and 3 and WWi process should dispatch new WWI requests to 2 and 3. Only if now again the next request crashes WWi server 2 and the next crashes WWI server 3 you have no WWI service/server up and running

So you should check now the other way around. if one process was "killed" the corresponding request is "hanging" and if so you should see this in CG50. Here we have the status "System error", "Genereation possible" and a third one (can not remember). You should check:are there any lines in Cg50 having this status?

If so there might be the chance that the "data constellation" and the new template (you have done SERC update) rises "issues" in generation process.

If now you have such entries and you are able to restart any WWI server and action is repeated: is once again the WWi process crashed? => if so: there is a good chance that either data constellation and/or  template used crashes the process

The next option could be: use your "qual" system. Try to set up data as needed and generate the "similar" report once again (assuming that WWI version of qual and prod is the same), By digging deeper here you might be able to get the reason.

I assume. if you find somethign in live system in CG50 that "report from template "works correct ? and report is shown? Do you know. is WWI version on client and server the same?

Please refer to the document which i have shared. If you dig deep you will get this impression: you are not alone ! (not so good news ?!) and others have similar issues and there is always a solution (good news). BUt to find the reason is quite "special"..

C.B.

PS: weeks ago i have had different experience in different area (not related to WWi stuff). It took my one day to realize that we have had a performance issue and therefore the writring of data to database was delayed a lot (and therefore subsequent process was not trigggered as expected)

As explained the document: YOU CAN BE HAPPEY if WWi process is up and runnning; and if something happens

it "easy" thet you wil be very "unhappy" as you need otinvest a lot of time to find the reason.

PPS: any update of Operating system, WWI version, Word version, template version etc. can create such effects sometimes so that you will be unhappy (and WWi process is stucking)

PLease come back if you have found something Cg50 (in my opnion: there must exists something) as explained

Dear Anna

if I remember correct:

WWI_GENSERVER_SYN_ANCHOR

WWI_GENSERVER_SYN_DEST

are used only for "GLM". What type of report was generated now (which lead to crash)

C.B.

[Former Member]

oh i just listed the Parameters we checked, i was wondering what These two were for, since we do not use GLM.  haha

[Mark-Pfister]

Hello,

These parameters are for the Synchronous WWI Server. You can use the synchrons WWI Server for GLM - or to replace your local WWI installations.

Dear Anna

the WWI server (if you have only one) is used to

a.) create reports

b.) support SDS/MSDS dispatch

For b.) normally this is processed "in night". So at whcih point in time is your WWi server down?

if a.) applies: then this should be realized normally by the user during report generagtion (Create report). The user will then (in most cases) try to use CG50 to releease the report. If WWI server is "down" in most cases the process stuck in e.g. "generation possible" status. So the user should provide hints to support team at which point in time the process get stuck; then you can dig deeper. Currently in your situation it is like to look for the needle in a haystuck.

IN parallel threads: you can activate on WWI server side "full logging" (but you should not use this option (in most caaes) for  long time period). If you now detect that "nothing is like you expect" then you can check the log. The log is providing useful information if the issues can be linked to WWI server process

IN parallel thread. there are as well options to monitor"RFC" activities (here I am not the expert). IN paralle thread indicaiotn was given that the RFC connection between SAP and WWi was down; this is as well a reaons of potential issues

In any case. you can now do a WWi set up like that that if WWi server is "down" by whatever reason

a.) a person is informed

b.) and a restart is executed (hopefully then leading to success)

I do not believe that your issue is coming up becuase of your SERC update as SERC update (according to my knowlegde) should have no effect on WWI set up

C.B.

PS: WWI topic are the top 5 asked ones; with the new capabilities of WWi the system is more stable. This was delivered by SAP may be with SP 35 or so. So if you have eg. SP 40 you are on quite "safe side" but to have the current version is much better

PPS: Still there is some rumor that SAP tries to figure out if there is the option in future SAP releases to use a different process than WWI to generate documents. Currently. SAP delivers only (as part of EnhPack) the optionto exchange WWi by something different. But here you must do the whole job; there is no default implementation (the default implementaiotn just "redirect" to WWI environment)

[christoph_bergemann]

Dear Anna

please explain your WWI scenario better, This is what I understood

a.) you have only one WWI server used (quite very low number)

b.) you use CGSADM to configure

1.) I assume. RFC connection is up and running and configured (assuming) UNICODE

2.) no update (even small ones) of operating system happened on WWI server. no change in Word version or WWI version was done on the server

In context of "it hangs or gets stuck, and by coincident we see it and then restart the Server or Trigger in CGSADM the Server."

We have now many mechanisms "on board" so that WWI will be startedt !automatic" dispacth error mails to "support" etc. These are avaiiable in lower version of WWi as well

There are some threads existing discussing this set up, e.g. TSG - Issues During Generation of WWI Reports - Product Lifecycle Management - SCN Wiki

is a quite nice documebt to look at; but may be check as well:

The "set up of WWI" and to have it up and running 24 hours 7 days is one of prio one topics to discuss here.
