Troubleshooting Steps for iUnique

iUnique is a clustering tool that helps identify ticket resolutions for groups of tickets rather than individual ones. This troubleshooting guide provides steps to resolve common issues such as service not starting, internal server errors, resource not found errors, and not receiving any response.

iUnique helps in clustering of tickets with similar ticket descriptions. This helps in identifying resolution over a group rather than catering to individual tickets. It is a component developed using python and is hosted on Apache Web Server as a service under the name HCL.iAutomate.iUnique

HCL.iAutomate.iUnique service is not starting

Table 1. Table 96 - iUnique: Scenario 1
Issue Description HCL.iAutomate.iUnique service is not starting
Modules Impacted iUnique
Probable Root Cause Invalid “iUnique.conf” file content

Steps to resolve

  1. Check for existence of the file iUnique.conf at location <Apache_Root_Folder_Path>/conf.

For e.g. - “C:/Apache24/conf” has <Apache_Root_Folder_Path> as “C:/Apache24”.

  1. Verify the contents of file iUnique.conf by checking the snippet with paths to << iUnique_Directory>>. Verify and change the <VirtualHost *> tag with correct path entries to << iUnique_Directory>> as shown below. Where << iUnique_Directory>> is “C:/iAutomate/Comp/HCL.iAutomate.iUnique” in the snippet from iUnique.conf.

<VirtualHost *>

WSGIScriptAlias /iAutomate C:/iAutomate/Comp/HCL.iAutomate.iUnique/iUnique/app.wsgi

SSLVerifyClient require

SSLVerifyDepth 10

<Directory C:/iAutomate/Comp/HCL.iAutomate.iUnique/ iUnique>

WSGIApplicationGroup %{GLOBAL}

Require all granted

</Directory>

</VirtualHost>

  1. Ensure that service was created through Service Account and not through Local account. Refer to below figure to check the status.
Figure 1. Figure 142 - HCL.iAutomate.iUnique service is not starting
  1. If not, open Windows Command Prompt in Administrator mode and run the below command:

sc config HCL.iAutomate.iUnique obj= “ID” password= “PSWD”

where ID is the [Domain\SA ID] and PSWD is the [Password of SA] and SA is

[Service Account].

Log On As’ field corresponding to the service HCL.iAutomate.iUnique should be changed to ‘Service Account’. Click Start to start the service.

Service returns Internal Server Error - status code 500

Table 2. Table 97 - iUnique: Scenario 2
Issue Description Service is reachable but returns Internal Server Error with status code 500
Modules Impacted iUnique
Probable Root Cause Python package not available

Steps to resolve

  1. Check the Apache error log at <Apache_Root_Folder_Path>/logs/error.log.
  1. If the error is because of the missing package, perform the following steps:
  1. Open Windows Command Prompt in Administrative mode in Apache_Root_Folder_Path.
  1. If open internet access is available, run the below command:

pip install package_name

  1. If open internet access is not available, download wheel file for the package from where user has internet connectivity and move onto server at same location where it needs to be installed. E.g. https://pypi.org has a repository of most used wheel files, else other sources are available as well. Subsequently, run the below commend:

pip install package_name.whl

‘404 Resource Not Found’

Table 3. Table 98 - iUnique: Scenario 3
Issue Description Error message ‘404 Resource Not Found’ when iUnique is hit
Modules Impacted iUnique
Probable Root Cause
  • Paths are not correct in iUnique.conf
  • Port is not correct

Steps to resolve

  1. If the issue is due to the incorrect paths, refer to resolution steps mentioned for issue in Table 96 - iUnique: Scenario 1 .
  1. Also, check if correct port is being used. To identify the correct port, perform the following steps:
  • Open iUnique.conf
  • Search for Listen xxxx

e.g. – Here the image below shows the port set for iUnique component is 9000.

#

Listen 9000

# ports, instead of the default. See also the <VirtualHost>

# directive

  1. The set port is one where iUnique is deployed.
