Mirth and E-Biz

[gdoyle]

Hello all,
After a month of test, we put Mirth in production.

The test has be done whith Mirth V1.3 and V1.4, Java 1.6, Win2k server .

We have a single LLP listener, et 4 output channels .

Nothing, special, just strings and segments manipulation.

The first problem is since we receive socket (LLP) message from E-Biz engin, the LLP listen stop to receive without warning or error, and E-Biz cannot re-open the connexion. If I restart the channel, the communication resume with success, until the next cut off... We can run some time a day without problem, sometime we have 4-5 cut off a day. We process 1000 messages / day

The second problem, the Java.exe take 100% after received de first message. If a restart the channel , the CPU goes normal.

I have isolated the receiving (LLP) channel, the new channel receive only the message from E-biz, and without modification put the hl7 message file in de specific directory.

Same problem, after first message de java.exe took all CPU. With this test the problem of listening with E-biz has not be seen. May be it's to early to confirm that.

Any suggestions ?

I will switch with version 1.5 and try the new options in the LLP listening (GE Centricity/MIK hint).

Thank you.

Gilbert.

Re:Mirth and E-Biz

update...

The connexion with E-Biz still problematic

Next step upgrade to 1.5...

Re:Mirth and E-Biz

1.5 has a complete overhaul of the LLP receiver (with the ability to enable pre 1.4 options (Use Strict LLP)) Give it a try and let us know how that works.

Re:Mirth and E-Biz

I have installed th 1.5.
After channels import, and validation, a got this message.

I will create one from scratch...

If I stop the receiver channel and restart it, I get this message on console.

Re:Mirth and E-Biz

Update:

After somes tunning, I finally get it working.

It seems stable, no cut off. Still need more time to validate.

In the console a get again this messages when I stop the channel.

Debug message ?

Re:Mirth and E-Biz

As I understand, "Sleep Interrupted" error is "harmless" and may be ignored. This problem has been fixed. Please refer, http://www.mirthproject.org/communit...owse/MIRTH-393.

Re:Mirth and E-Biz

Update:

I still have the problem with LLP listener.

I have try all kind of setting.

Mirht stop listening... after dozen messages.

I have stop the channel, and use nc.exe to listen the port (nc.exe -l 6661 >dump.hl7).

E-Biz send me the message correctly.

After somes start and stop... nothing appended. The LLP listener still frozen.

I have restart with version 1.4 and the channel have started with success.

...

To be continue

Re:Mirth and E-Biz

Update:
I still running version 1.4.

I have change LLP receive timeout to 0. I run this setup since couple of hours without problem..

I cross my fingers... Just the CPU is at 100% busy with Java.

To be continue..

Re:Mirth and E-Biz

Update:

With receive timeout to 0, the connexion is more stable, but not perfect...
I will change the channel to file reader.

It will close this thread.

Thanks to all.

Re:Mirth and E-Biz

Just so you know, the 100% cpu is likely an unrelated issue, and it won't happen in 1.5+.

We are still looking into why LLP stops responding for you. It seems to be a fairly rare problem.

Re:Mirth and E-Biz

For the CPU, it will happened on LLP receiver on 1.4 only and it was random.

For the LLP problems, I didn't have the control on E-biz, and I was the only customer with this probem.

It was hard to have support. And the system is in production.

When all will be stabilized, will reinstall the version 1.5 and dig more deep to find what's append.

Re:Mirth and E-Biz

gboyle, I have looked into your problems more and they can be solved by turning Keep Connection Open to off. Instead, if you would like to keep the connection open, simply set the receive timeout to 0 (infinite).

This option is causing your 100% cpu usage problem and also causing your channels to stop receiving messages.

Thanks,

Jacob

Re:Mirth and E-Biz

great !

I will make more tests this summer.
Thank you.
