Hibernate with infinispan invalidation cache in a cluster

I am using Hibernate 5.4.22 with Infinispan 11.0.4 in a cluster environment. Hibernate second level cache is configured to use the JCache provider:

ANSWER

Answered 2020-Nov-06 at 09:08

The problem is using JCache - the table assumes InfinispanRegionFactory instead of JCacheRegionFactory.

It seems that Infinispan does not have a module to support Hibernate 5.4 explicitly - I would guess that modules to support Hibernate 5.3 should work even with Hibernate 5.4, though, since there hasn't been much changes in the second-level-cache land in Hibernate 5.4.

I am surprised that 2LC works with JCache at all with replicated/distributed caches - I would be pretty sure that it does not work 'reliably' (transactionally, covering edge cases etc.) anyway.

SQL Azure database connection issue

Asked 2020-Aug-27 at 07:20

My problem is, I am getting below error when I try to connect the SQL Azure database by using SQL authentication from the Azure VM. The problem is interesting because I can connect same database from different Azure VM. SQL Server has a firewall and both VM IP addresses are whitelisted. I tried to make tcpping to SQL destination from both VM works fine. Unfortunately, I don't have access to grab the azure diagnostic log from the destination SQL Server. Does anyone have any clue what could be the problem?

Error message:

Cannot open server "XXXXXX" requested by the login. The login failed.

Congratulations that you resolved the issue:

"Yes, I was able to resolve the issue by moving VM to another vnet. It was using private IP even though it has public IP, I believe because of subnet service endpoint configuration"

I help you post it as answer and this can be beneficial to other community members.

Keycloak(Wildfly/Infinispan) in HA mode - issue in detecting other machines in the cluster

Asked 2020-Jul-13 at 12:36

As a result, when I put the machines under an ELB, the login doesn't work. I have tried TCP and UDP for IP casting. Tried using TCPPING instead of MPING (although not sure whether I used them correctly). Infinispan is being used for distributed caching. Here is the default configuration, followed by the changes I had made:

This is how I debugged it:

Make sure that jgroups-tcp and jgroups-tcp-fd is listening to public interface, and not private interface. These properties are in standalone/configurations/standalone-ha.xml.
While starting the the instances of your cluster via bin/standalone.sh | bin/standalone.bat make sure you pass -b and not 0.0.0.0 (all interfaces). To find the public interface IP, run the following command:

ifconfig eth0 | grep -i mask | awk '{print $2}'| cut -f2 -d:
When you start the first instance (should be the instance you passed in initial_hosts property; you can try telnet 7600 to test if your TCPPING is working or not. It should work for cluster discovery.

Current transaction was aborted (probably due to a timeout, but maybe as a consequence of delivery failure). You need to rollback current transaction and start new.

However let me note that 5.3 was released 2013/06/26 - you're using almost 7 years old version. If there is a bug, no-one will even try to check it out.

Azure Regional VNet Integration and Service Endpoint

Asked 2020-Apr-28 at 01:48

I try to integrate a web app to a VNET. this is a brand new subscription.

According to : Integrate your app with an Azure virtual network

In the first step I wanted to check if the web app could reach out to VNET. The second step I want to connect the web app to SQL database through a Service Endpoint

I created a VNET with 2 subnets:

Jumpbox-subnet
integration-subnet

integration-subnet setting

There is service endpoint pointing to the integration-subnet. Also I integrated the app to the VNet, It's delegated the integration subnet. I tried to connect to VM from App using tcpping 172.16.1.0 (jumpbox VM private address) from app console, but it failed. I also app cannot connect to the sql database.

What are the missing pieces here, is a DNS server required to make this work?

Update (Resolved):

The question above was the key, It needs away to resolve the name with some sort DNS server.

tcpping default port is 80 and nothing was listening to that port in that box.

ANSWER

Answered 2020-Apr-27 at 07:49

You could use the tool tcpping to test for TCP connectivity to a host and port combination.

The syntax is: tcpping.exe hostname [optional: port]

For example, run tcpping 172.19.1.10:3389

See troubleshooting app service networking for more details.

For more references, Here is an ARM example to deploy an app service with VNet integration and enable service endpoint Microsoft.Storage.

Azure Web App is not connecting to On-Site SQL Server via VPN using connection string

Azure app service (ASE) SQL Azure connection

Asked 2019-Dec-16 at 09:08

I have an app service located inside the app service environment(ASE). I have a virtual network which I have put ASE into the subnet in the Vnet.

What I am trying to do is, I am trying to connect SQL Azure endpoint which is not in Vnet or my azure tenant. ASE has an outbound IP address and when I try to tcpping to azure SQL endpoint, it is responding me without any issue.

The problem is when I try to connect SQL endpoint inside the application, I am getting "Cannot open server" error. It usually happens when there is firewall in SQL Azure endpoint. I have checked log analytics (in target SQL endpoint) and saw my app connection is blocked but when I check the client IP, it shows me private IP of ASE. I really don't understand how it can be possible? I would see my public ip in there, since ASE is external ASE.

Do you have any idea how that can be possible?

...

ANSWER

Answered 2019-Dec-16 at 09:08

If you have enabled the virtual network service endpoint for Microsoft.Sql in the ASE subnet, When you connect to your Azure SQL server with service endpoints turned on, the source IP of SQL connections will switch to the private IP space of your VNet.

If so, you need to allow the given VNet/subnet by specifying it in the VNet firewall rules of the SQL server. If you do not want to use a virtual network service endpoint, you can whitelist the outbound IP address of the application in the firewall of the SQL server.

For more information, you could read the blog1 and blog2.
