Cognos Analytics 11.1.7
Microsoft Windows 2019 server

Problem:
How do i change CA11 WLP to use balanced in java?

Suggested solution:

The log file cbs_run_WebSphereLiberty.log say “CBSBootstrapService attempt to load config from “C:\Program Files\ibm\cognos\analytics\bin64/bootstrap_wlp_winx64.xml”
This should mean that the WLP is controlled from the file bootstrap_wlp_winx64.xml. Open file in Notepad++
Change line 37 to;

param condName=”${java_vendor}” condValue=”IBM”>-Xgcpolicy:balanced</param>

save the file and restart the server, will give that WLP use garbage collection Balanced instead of default gencon. Then this will not help you, if you not have a big solution that maybe need it.

WLP settings for Planning Analytics is on the other hand stored in file C:\Program Files\ibm\cognos\tm1_64\bin64\bootstrap_wlp_tm1_winx64.xml

Normally you add the line -Xgcpolicy:balanced to the file C:\Program Files\ibm\cognos\tm1_64\wlp\usr\servers\tm1\jvm.options instead, of doing above.

Edit C:\Program Files\ibm\cognos\analytics\wlp\usr\servers\cognosserver\jvm.options to have the line -Xgcpolicy:balanced  will not work with CA11. You may need to do something more….

Product:
Cognos Analytics 11.1.7
Microsoft Windows 2016 server

Problem:
After upgrade of Cognos and the IIS gateway settings the large dashboard with many columns does not work. If you use less columns the dashboard work. Error like this:

We can’t retrieve the data from data set….

Solution:
Inside IIS Manager on your Microsoft Windows server, check the values for Maximum URL length.
Go to your ibmcognos\bi folder and click on “request filtering”.

Click on edit feature settings on the right side.
Update to 8192 or 16000. (adjust other values as needed)
Click OK (the values are saved in C:\Program Files\ibm\cognos\analytics\webcontent\bi\web.config)
Restart the IIS service and test again.

The CA_IIS_Config.bat file should set this values in your windows server:

Product:
Cognos Analytics 11.1.7
Microsoft Windows 2016 server

Problem:
On a installation where you use SSL only to the IIS gateway, and not to the Cognos dispatchers.
When try to login to Cognos Analytics HTTPS portal you get a error similar to this;
HTTPS Error 404.0 – Not Found…
Requested URL  https://cognosserver.domain.com:443/bi/
Physical Path  c:\inetpub\wwwroot\bi\

Solution:
Run the CA_IIS_Config script with HTTP instead of HTTPS, so you change the Reverse Proxy Inbound Rule to have Rewrite URL http://ca_servers/bi/{R:0} instead of HTTPS.
Add the certificate server name to the IIS manager – Default web site – bindings. Edit the settings for HTTPS port 443, so you have a host name in the host name field.

After any change to IIS, restart it from a DOS prompt with command: iisreset

From your web browser test that you can browse to the Gateway URL;
https://caservername.domain.com:443/ibmcognos/bi/v1/disp

Product:
Cognos Analytics 11.1.7
Microsoft Windows 2016 Server

Problem:
After upgrade to CA 11.1.7 in a Multi server solution the event studio events are not running all the time, and also you get other errors in cogserver.log file.

Error:
CNC-ASV-0048 Error building report template: {0} CNC-ASV-0048 Error building report template: PRS-REQ-0760 The operation “/” “” “xts.run” is invalid.

javax.net.ssl.SSLPeerUnverifiedException: Certificate for <servername> doesn’t match any of the subject alternative names:…

CNC-SDS-0222 An error occurred while trying to send a message in message manager

Suggested Solution:

Upgrade your installation to the latest Fix Pack of CA11.1.7
https://www.ibm.com/support/pages/ibm-cognos-analytics-11x-fix-lists

If you restart the IBM Cognos windows service by some script, change the script to instead use the Cognos Configuration program to do the restart. Create a CMD file with this content:

REM https://ss64.com/nt/call.html

call “C:\Program Files\ibm\cognos\analytics\bin64\cogconfig.bat” -stop

PING -n 31 127.0.0.1>nul

call “C:\Program Files\ibm\cognos\analytics\bin64\cogconfig.bat” -s

Name the file c:\scripts\birestart.cmd and put your schedule software to use that, instead of the NET STOP command, as stopping Cognos BI from windows may corrupt some temp files.

CA 11.1.7 demands that all server names are in FQDN format.
Stop the Cognos BI service on Windows from Cognos Configuration.
Update all the server name in Cognos Configuration to be FQDN and lowercase. Also ensure the Server Common Name, under Security – Cryptography -Cognos, is the FQDN server name.

https://www.ibm.com/support/knowledgecenter/SSEP7J_11.1.0/com.ibm.swg.ba.cognos.inst_cr_winux.doc/c_reviewthedefaultsettings.html

Before start of the Cognos from Cognos Configuration, clean out some folders to ensure there are no old settings around.
Backup and then remove the analytics/configuration/data/flipper folder
(You need a backup of flipper folder, like file flipper\config\global\configuration0.properties, as it will erase your new cognos advance settings, or you need to manually add the values back.)
Backup and then remove the analytics/configuration/data/discovery folder
Backup and then remove the analytics/wlp/usr/servers/cognosserver/workarea folder
Backup and then remove the analytics/wlp/usr/servers/dataset-service/workarea folder
Backup and then remove the analytics/javasharedresources folder
Backup and then remove the analytics/temp folder
Backup and then remove the analytics/logs folder
Backup and then remove the analytics/data folder

You can check the setup of Configuration Group by browse in IE to the server first on
http://caservername.domain.com:9300/bi/v1/disp
and login, then change the URL in IE, and browse to http://caservername.domain.com:9300/bi/v1/flipper/diag
This json file can be saved.

If you have old reports that fails, please try to upgrade the reports to the latest version.

1. Open IBM Cognos Administration.
2. On the Configuration tab, click Content Administration.
3. Click the arrow on the new content maintenance button on the toolbar, and then click New Report Upgrade
4. Type a name for the upgrade task and, if you want, a description and screen tip. Click Next.
5. Select the packages and locations for the report specification you want to upgrade. Click Next.

   If you upgrade report specifications by folder, all reports in the folder will be upgraded.

6. Choose one of the following:
   • Save and run once opens the run with options page.
   • Save and schedule opens the scheduling tool.
   • Save only allows you to save the upgrade so that you can run it at a later time.
     

   Give time to upgrade all reports and all templates in your Cognos solution. To upgrade users my folders, select Directory – My Folder of AD (your namespace).

If schedule or events are not working, try dropping the NC* tables with this script:

1. Stop the Cognos Service
2. Take a physical backup of the Content Store or Notification database
3. Select the appropriate folder for your content store or notification database type ,like C:\Program Files\ibm\cognos\analytics\configuration\schemas\delivery\sqlserver for SQL.
4. Run NC_DROP_MS.sql against the content store or notification database in Microsoft SQL Management Studio.
4. Restart Cognos Services.

Should dropping the NC* tables not resolve the issue, then restore the content or notification store from the last backup version.

CA 11.1.x have made changes to the IIS setup for URL rewrite, manually change IIS settings to the new values or use the script in folder: C:\Program Files\ibm\cognos\analytics\cgi-bin\templates\IIS
https://www.ibm.com/support/pages/automate-configuration-microsofts-internet-information-service-support-ibm-cognos-analytics

Check the rules under ibmcognos and bi folder in IIS manager. Compare yours to the latest webpage https://www.ibm.com/support/knowledgecenter/SSEP7J_11.1.0/com.ibm.swg.ba.cognos.inst_cr_winux.doc/t_gateway_iis.html

Cognos Analytics 11.1.7
Microsoft Windows 2016 server

Problem:
There are 3 jave.exe on the Cognos Analytics server, what are they for?

Solution:
Java.exe (with most memory usage is Query Service, if you use Dynamic Cubes) command line c:\program files\ibm\cognos\analytics\ibm-jre\jre\bin\java.exe
Java.exe (with command line ..\ibm-jre\jre/bin/java.exe is the Content Manager and WLP service for the cognos portal) it have -Xgcpolicy:gencon
Java.exe (with least memory usage is the exploration engine in CA11) command line c:\program files\ibm\cognos\analytics\ibm-jre\jre\bin\java.exe” -Xms1024m -Xmx8192m -XX:MaxDirectMemorySize=512m

The 3 java.exe process for exploration in CA11 is part of the query service and is configured with advanced parameters in cognos connection;
https://www.ibm.com/support/knowledgecenter/en/SSEP7J_11.1.0/com.ibm.swg.ba.cognos.ug_cra.doc/t_ca_query_coprocessing.html

1. From Manage > Administration console, open Cognos Administration.
2. On the Configuration tab, click Dispatchers and Services, and click your dispatcher name.
3. In the list of services, locate the Query service, and click its properties icon .
4. On the Settings tab, under Category, select Environment.
5. Next to Advanced settings, click Edit.
6. Select the Override the settings acquired from the parent entry check box.
7. Type or copy the parameter names and their values, from the Cognos documentation.
8. Click OK.
9. Restart the Query service.

The Java.exe for Query Service memory usage is also controlled from cognos connection.

JVM heap size limit for the query service: Specifies the maximum size, in MB, of the JVM heap.

JVM garbage collection policy: Specifies the garbage collection policy used by the JVM.

Go to Cognos Administration page, and click on System in the left.
Click the arrow at All servers and select Services – Query.
Now you only see the QueryService for each server. Click on arrow and select Set properties.
Change the Initial JVM heap size for the query service to a unique value like 2048, then after a restart it is easier to tell the jave.exe apart from each other.

The Java.exe for content manager and WLP is setup from inside Cognos Configuration.
If you have the RAM in the server, it can be increased to 24576 MB.  The start up time of Cognos will be longer, when the WLP use more memory.

1. Start IBM Cognos Configuration.
2. In the Explorer window, expand Environment > IBM Cognos services, and then click IBM Cognos.
3. In the Properties window, change the value for Maximum memory in MB.
   • To reduce the startup time, memory footprint, and resources that are used, use the default setting of 8192.
   • This value can be adjusted based on available system resources.
4. From the File menu, click Save.
