• Issue: While upgrading from Foundry 7.3 to Volt MX Foundry V9 and then upgrading to a version after V9, the upgrade fails due to the following error:"java.sql.SQLSyntaxErrorException: Table 'prefixidglobaldbsuffix.schema_version' doesn't exist".

  Workaround

  To avoid this issue, perform the following step:

  • Delete the idglobaldb schema before upgrading to the version later than V9.

• Issue

  The upgrade installation from v8.2.1.3 to v9.x rolls back.

  Workaround

  Before the upgrade, execute the following SQL statement from admin database:

  For MySQL
  ------------
  delete from .schema_version where script = 'V62.1__voltmxadmin-mysql-8.2.0.0.sql';

  For SQLServer
  ---------------
  delete from .schema_version where script = 'V62.1__voltmxadmin-sqlserver-8.2.0.0.sql';

  For Oracle
  ----------
  delete from .schema_version where script = 'V62.1__voltmxadmin-oracle-8.2.0.0.sql';

• Issue

  If you upgrade the integration service or install on new server using the existing database but with a different server details like fully qualified URL port, and when you publish an app, the app publish fails.

  Workaround

  You must update management server details in the server_configuration table in admin database.

• How to change the Hostname/IP address and port details of the existing Volt MX Foundry Server.

  After the installation of Volt MX Foundry, if you want to change the existing Hostname/IP address that was used during the installation of Volt MX Foundry, follow these steps:

  1. Go to your Volt MX Foundry install folder.
  2. Go to scripts folder - for example, <MFinstallfolder>/scripts. The scripts folder contains a .sql file for the database type that you selected while installing Volt MX Foundry.

  3. Open the .sql file in a text editor.

     Important: If you want to access Volt MX Foundry Console with a new port, change the value for the NEW_PORT with the new value. Otherwise, assign the value of the OLD_PORT to the NEW_PORT variable.

     Important: If you want to access Volt MX Foundry Console with a hostname/IP address, change the value for the NEW_HOST with the new value. Otherwise, assign the value of the OLD_HOST to the NEW_HOST variable.

  4. Change the values for the following variables.

     • For MySQL, MariaDB, DB2, and SQL Server, replace the values for the NEW_HOST and the NEW_PORT with new values.
     • For Oracle, replace all the occurrences of the NEW_HOST and the NEW_PORT with new values.

     Important: If you have selected your database as DB2, follow the steps provided in the .sql file in the <MFinstallfolder>/scripts folder.

  5. Run the SQL script on the database where you have installed Volt MX Foundry.

• Issue

  If the java.sql. BatchUpdateException: Prepared statement needs to be re-prepared error is logged in the Identity service logs or if certain operations fail to work properly when an identity service is invoked, do the following.

How to Configure Heap and PermGen Size

Configuring Heap and PermGen Size for Tomcat

By default, the heap settings for Tomcat allocated are Min -Xms1024m / Max - Xmx2048m, and default permgen settings are: -XX:PermSize=1024m -XX:MaxPermSize=1024m

For better performance in case of several publishes, update the following heap and permgen settings  in the file: {Installation directory}/tomcat/bin/catalina.sh

• heap settings: Min -Xms1024m / Max - Xmx1024m.

  Important: While installing Volt MX Foundry Components including Integration services, set the heap settings to: Min -Xms2048m / Max - Xmx2048m.

• permgen settings : -XX:PermSize=1024m -XX:MaxPermSize=2048m

Configuring Heap and PermGen Size for JBoss

In case of multinode, do the following:

• Configure the Min -Xms2048m / Max - Xmx4096m heap settings in the file: { Server directory }/domain/configuration/host.xml
• Configure the Min -Xms2048m / Max - Xmx4096m heap settings in the file: { Server directory }/domain/configuration/domain.xml
• Configure permgen settings : -XX:PermSize=1024m -XX:MaxPermSize=2048m

In case of single node, configure the settings in { Install directory }/jboss/standalone/configuration/standalone.xml

How to Configure Volt MX Foundry Behind a Reverse Proxy

If you want to access everything via a proxy URL, including Volt MX Foundry Console (for example, design time for your app developers) and authService, and integration services (for example, runtime from users using your apps), follow these steps:

1. Install Volt MX Foundry with internal details like your internal IP and HTTP port.

2. After installation, stop the Volt MX Foundry Console (without configuring authservice details) and update following property files:

   1. In the  accounts.war/WEB-INF/classes  folder, open the accounts.properties  file, and update the WAAS_BASE_URL=<PUBLIC_URL_OF_YOUR_APACHE>/workspace property with a public URL instead of the private URL. By default, the private URL is set during installation.

      Examples of proxy URLs:

      • WAAS_BASE_URL=http://test.voltmx.com/workspace
      • WAAS_BASE_URL=https://test.voltmx.com:8443/workspace
      • WAAS_BASE_URL=http://test.voltmx.com:8080/workspace
        1. Following are the changes to be made in the war for each App Server:
      • Tomcat: In mfconsole.war/WEB-INF/classes, open the config.properties file, and update the VOLTMX_ACCOUNT_API_BASE_URL=<PUBLIC_URL_OF_YOUR_APACHE>/accounts/api/v1_0/ property with a public URL instead of the private URL that was generated during installation.
      • JBoss - Standalone (Bundled JBoss): In Standalone/deployments/mfconsole.war, open the config.properties file, and update the VOLTMX_ACCOUNT_API_BASE_URL=<PUBLIC_URL_OF_YOUR_APACHE>/accounts/api/v1_0/ property with a public URL instead of the private URL that was generated during installation.
      • JBoss - Pre-configured and Domain mode: Take a backup of the existing war. Undeploy mfconsole.war. In mfconsole.war/WEB-INF/classes, open the config.properties file, update the VOLTMX_ACCOUNT_API_BASE_URL=<PUBLIC_URL_OF_YOUR_APACHE>/accounts/api/v1_0/ property with a public URL instead of the private URL that was generated during installation, and re-deploy the war file.

3. Start Volt MX Foundry Console.

4. Launch your Volt MX Foundry Console in browser by using <PUBLIC_URL_OF_YOUR_APACHE>/mfconsole. Now auth setup pages comes up.
5. Enter auth URL with public URL like <PUBLIC_URL_OF_YOUR_APACHE>/authService. If you provide an internal IP here, appconfig will show internal IPs.

6. Also after log in to Volt MX Foundry Console, while registering server, provide the PUBLIC_URL to register integration server. Now all the URLs will have the public hostnames.

   If you want to give public access only to runtime services like authservice and integration services you can skip step 2 and step 3 from the above procedure. This will make sure service doc will have all public URLs.

   Note: Proxy configuration should have preserver host directive for Volt MX Foundry to work correctly after start up.

   For example, in case of apache proxy, use `ProxyPreserveHost On`and in case of NGINX, use proxy_set_header Host $host; (For more information, refer Passing request headers)

How to Configure Frontend HTTPS to Tomcat HTTP Redirection

If you are installing Volt MX Foundry on Tomcat on HTTP and wants to route requests via HTTPS apache or loadbalancer, add a connector in the tomcat/server.xml with the following attributes:

proxyName="" proxyPort="" scheme="https" secure="true"

Example: `<Connector server="VoltMXTEST" port="8080" protocol="HTTP/1.1" proxyName="mbaastest10.hcl.net" proxyPort="443" scheme="https" secure="true" maxHttpHeaderSize="8192" maxThreads="150" enableLookups="false" acceptCount="25" disableUploadTimeout="true" tcpNoDelay="true" compression="on" compressableMimeType="text/css,text/javascript,text.html" connectionTimeout="20000" URIEncoding="UTF-8"/>`
