Error when resetting a valid ALM Connection URL in PC Servers module of ALM Lab Management project

In the Lab Management project (“LAB_PROJECT” project in “DEFAULT” domain available in http://<server&gt;:<port>/qcbin/start_a.jsp?projectType=LabManagement) of Application Lifecycle Management (ALM), one of the configurations required for allowing integration of Performance Center (PC) server with ALM server is in the ALM Connection button available in the Servers\PC Servers module. In ALM12.0x\PC12.0x, using this button more than once to set a valid and available URL of ALM server will cause a popup error message: “Host is unreachable. Please ensure that host’s name is correct.”

This is a defect in PC12.0x.

If there is a need to reset this ALM Connection settings after having it already changed in the same ALM session, it is recommended to logout and login back from the Lab Management project and then try to reset ALM Connection settings (it is recommended to avoid changing this setting more than once in a single ALM session).

Performance issues with large number of active projects on Oracle

The ALM environment may experience slow performance for a period of time, and new database connections may be refused.

This problem may affect large ALM environments (over 500 active projects) configured to work on an Oracle database. Both ALM-PC and pure ALM environments may be affected.
PC’s PAL orphan maintenance task connects to the schema of each active project every predefined interval (default value is 1440 minutes).
This can result in a large number of open database connections which can cause slow performance until the database connections are closed.

To fix this issue

Disable the PAL maintenance tasks.
To disable the tasks, execute the following SQL query directly on the LAB project schema:


SM table alertm1 grows very fast

If alerts are DEFINED in Task Phase record, the alerts will be CREATED.

To avoid creation of schedule and alert records, the alerts need to be deleted in Task Phase.
If you don’t need the old alerts, you can delete them.

To avoid creation of
• schedule records “T24 – notice – cm3t” and “T24 – not assigned – cm3t”
• Alert records “notice” and “not assigned”

you need to delete the “Alerts” in the Task Phase definition:

1. Change Management – Tasks – Task Phases
2. search for the Phase you want to update
3. Click on tab “Alerts/Open & Close Behavior”
4. Delete the entries in “Alerts” array (which are in OOB “not assigned” and “notice”)
5. Save Task Phase record

VuGen is unable to save imported Libraries in TruClient

When importing a Library from Develop Script -> Function Libraries and saving it, everything is fine. But when closing the Develop Script mode and opening it again, the library is not shown.
The script is not able to parse the XML files correctly. It could be due to crash of VuGen before the script became corrupted or if the script replay is interrupted unexpectedly. If something unexpected happened, VuGen can get corrupted and the reading process may be incorrect.
The following can help to fix the issue:
1. Take the .xml files from the “libraries” folder (within the script folder) and put them out of the script folder.

2. Delete the original files from the “libraries” folder.

3. Open the script with VuGen.

4. Go to Function Libraries.

5. Select the button “Import Library”.

6. Navigate and select the .xml files saved out of the script folder.

After doing this, the script will read/parse the XML files again and this time, it will be done correctly.
