Content Management and Capture

Hi,

I followed these steps, turned on eRRO, and restarted Windows Server.

Then, I accessed Verify panel from a Custom Navigtor Application and clicked Submit from 3 different browsers.

But I don't see eRRO.exe on the Task Monitor as explained in the Support page.

What steps must I proceed for eRRO.exe to launch and appear on the Task Monitor?

I used Chrome, FireFox, and Edge to access Navigator Verify panel and clicked Submit.

I was expecting to see 3 eRRO.exe processes.

①

Enable eRRO in Datacap

1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Datacap\RRS
2. In the right panel, right click "Use eRRO (REG_DWORD)"
3. Click Modify. Change the "Value data" from 0 to 1.
4. Click OK.

②

"On above image we can see how 2 sessions are running validations and how each of them has it's own eRRO.exe process."

On my system, it cause by Dstudio.   eRRO process is in window task manager if dStudio is started.  Not cause by IIS hosting wTM using datacap navigator.

According to the Support site, eRRO is a supplementary function for TMWeb and Datacap Navigator.

Do you know how eRRO can be launched for Datacap Navigator?

I couldn't understand why eRRO launched for DStudio. I thought eRRO was launched for each user on TmWeb or Datacap Navigator as stated in the Support page.

I will appreciate any clues.

"Enabling the eRRO registry for Datacap thin clients will allow a new separated process to execute the validation rules called eRRo.exe, this setting will create a separated process for each user running the verification view on TMWeb, and for Datacap Navigator will be generated while clicking submit on the verify.js page"

Hello Dsakai, 

I know it helps with speed running verify using datacap navigator.  I think it has to do with running it out of process or some sort.   If you are not using datacap navigator doing verify task, you don't need to enable this.

Thank you Duke

Hi, Duke-san. ( cc Sakai-san)
Thanks to your advice, I was able to see eRRo.exe in window task manager.
but it don't make sense that eRRo process is in window task manager only when Datacap Studio is started.
Datacap Studio is the tools for Datacap application development and testing and not related to RRS nor wTM.

It is hard to persuade my client.

eRRO processor are spawned when rules are executed.  It run out of processor ie ... outside of wtm processor which help with performance.

When you use datacap navigator or tmweb all the rule when it's executed are run in wtm processor or tmweb processor.   To help with performance, if you enable eRRO it will spawn new eRRO processing to run outside of wTM processor or tmweb.  You will see more than one eRRO processor if you have to execute different rule.

@AIKO YANAGIYAMA I don't know what dstudio spawn a erro processing.  I don't recall changing my registry setting.

Thank you Duke.

> When you use datacap navigator or tmweb all the rule when it's executed are run in wtm processor or tmweb processor. 

What is wtm or tmweb processor? Is it IIS Workerprocess? 

We have configured IIS to host wtm. 

Am I correct that eRRO.exe is spawned when IIS Workerprocess runs wtm rules and in addition the workerprocess has probably run out of resource?

eRRO processor are spawned when rules are executed.  It run out of processor ie ... outside of wtm processor which help with performance.

@dsakai

I didn't see your last post nor realized you still have some questions.
For timeout session, it's a loaded question.  I'll try to my best to answer.
I hope this timeout location will help.  see link.
https://www.ibm.com/support/pages/timeout-configuration-setting-options-ibm-datacap-navigator-environment

In IIS when you configure wTM and the app pool - there is a 20 min timeout setting.  You can extend the setting but it also have to adjust timeout on WAS also.

If you have load balancer you have to adjust that ip timeout also.  

https://www.ibm.com/docs/en/datacap/9.1.9?topic=options-setting-up-iis-host-datacap-web-services
