We suspect the issue is due to lacking of database connection resources.


Release : 14.4

Component : Identity Suite Virtual Appliance, external MS SQL database


Please do the following steps:

A. Increase max_workers_count parameter on IP database at MS SQL to 1024 if it is currently set lower than 1024.

To set max_workers_count parameter on IP database at MS SQL to 1024 you can use the following SQL statement. However, please check with DBA and consider and validate this recommendation.

EXEC sp_configure 'show advanced options', 1;  
EXEC sp_configure 'max worker threads', 1024 ;  

B. Adjust database pool connection to have the following parameter in IP standalone.xml using jboss-cli


To utilize jboss-cli to modify IP standalone XML, first of all, you need to create JBoss/Wildfly local management account. The following KB article gives the steps in its Resolution section to create the account. Please notice though, the steps in the KB article for wildfly-idm. Please do similar steps for wildfly-portal in this case.

Once you have the local management account, then
  a. Run the following to connect (e.g. the local management account is 'jboss-admin')

        /opt/CA/wildfly-portal/bin/ --connect --user=jboss-admin

      You will be prompted to key in the password for jboss-admin account. Key in the password and you should get the following prompt when it is connected successfully
      [[email protected]:9991 /]

  b. Run the following 4 commands to set the required pool parameter


  c. View /opt/CA/wildfly-portal/standalone/configuration/standalone.xml and make sure you have the following parameter for sigmadb pool section.


   d. exit the jboss-cli connection

   e. restart IP
