Has anyone noticed that when IRIS is forced down that the EnsLib.JavaGateway.Services do not properly shut down and release the ports? While we can write a shell script to kill the processes at the OS level, I was wondering if anyone experienced this issue.

We are working on our Mirroring setup/failover and had the team testing forcing the Primary down to make the Backup to become the Primary Server. When this happened and we failed back, IRIS could not restart the JavaGateway.Services because the ports were still in use.

I am looking into creating a ZSTOP as you probably have seen from my previous posts, is there a way to capture the type of shutdown that occurred? So say if there was an unknown hardware failure (forced), vs a user shutdown? Mainly looking for user or system shutdown when we force another destination to become the primary in the mirror. So if a user shutdown the production to do.,... Task A, Task B etc..

Thanks

I am new to setting up a mirror environment....

We will have a Arbiter, Two Failover members (A,B), and a Async (DR) member (C). I have the two failover members in sync and are configured for Arbiter Control.

My question is about the Async member, when I initially set it up I pointed it to the mirror on the primary node A.

Is that correct?

We are seeing more and more customers being lured with latest infrastructure technologies, particularly Composable Infrastructure. Coming with all sorts of data center consolidations and costs savings.

Question is: are there any concerns for HealthShare/TrakCare being run on these platforms or things to look out for? Anyone out there, already on these platforms?

To be more specific this is HPe Synergy with 480 Compute blades booting as bare metal.

Regards;

We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?

Thanks

Detecting and managing failover

I have Ensemble/Healthshare running in a production environment which is setup with a mirror failover and an arbiter sitting between them.

In the event of a failover we have a number of connections that need stopping/monitoring and starting in a certain order.

Is there a programmatic way we can detect the failover and stop certain services and operations immediately and then start them up again in the required order, checking their connection state before starting the next connection.

Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?

I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live. Or does this even matter?

timeout value

looking for what the timeout value is for the connection for shadowing. and if it is known the timeout for mirroring also.

I'm currently getting this error and when we go to mirroring it would be good to know also, this way we can go back to our network vendor and give them as much info as possible.

10/19/16-12:19:40:696 (d30b6) 2 [SHADOWING] SHADOW SERVER (PRODSHAD): <ZREAD>ReadNone+3^SHDWUTIL;ERROR #1071: TCP read timed out - remote server is not responding (repeated 16 times)

thanks

ISCAgent is automatically installed with Cache, runs as a service and can be configured to
start with the system. This is fine – but the complication comes when this is on VCS clusters with
Mirroring on. When installing a Single Instance of Cache in a Cluster, point number 2. Says “Create
a link from /usr/local/etc/cachesys to the shared disk. This forces the Caché registry and all
supporting files to be stored on the shared disk resource you have configured as part of the
service group.”
