DCM4CHEE-ARC-LIGHT v 5.16.2
Wildfly v16
Database:  mysql5
OS:  Win7


    Hello,

        Ever since v5.16.0 I've noticed CT exams are receiving very slowly to the archive (I'm using it as a DICOM router).  I also have GE RA600 installed on that same PC, and if I use it instead, the images are received and written to disk extremely fast compared to v5.16.x.

I can send a 200 + image exam to dcm4chee-arc-light and it might take 2 1/2 to 3 min, where the other software could get it in under 30 seconds.

I've recently upgraded to v5.16.2 and running wildfly16.  Is there debug I can temporarily enable to help troubleshoot this issue or any other setting that is recommend to change to help this slowness?

thank you

still having this issue after testing with 5.20.0 - how can I troubleshoot more?  Any help please?

I have also a new installation and I am still running ApacheDS M20 but have also upgraded to wildfly18.

Thank you

You may try to disable reverse DNS lookup - if that helps, check if DNS reverse lookup is working inside of the archive container.

Gunterze,

    Thanks for the response.  I'm looking for the logger int he wildfly management console, but all I see under categories are:

com.arjuna
io.jaegetracing.configuration
org.jboss.as.config
sun.rmi

Where can I find  'org.dcm4che3.util.ReverseDNS' to disable it?

Thank you

You can add logger categories yourself. But why you want to disable it? By default, there will be no logging of org.dcm4che3.util.ReverseDNS anyway, because it only logs on DEBUG level and the level of the root logger is by default INFO.

Gunterze,

    Thanks for your reply.  I have disabled logging all together to the console and to file in the wildfly management console, but it is still very slow receiving studies.  I have another system running wildfly12 that will accept studies very fast.  With this new installation, I used Wildfly18.  DCM4CHEE can studies after it receives them very fast, but its only when its receiving them is when it can take several minutes (which is unusual).

Can I install v5.20.0 and use wildfly12?  Just trying to do some troubleshooting to try and find out what is causing the slowness.  for LDAP I'm using apacheDs M24.

Thank you

No. 5.20 requires at least Wildfly 16. Also don't think that Wildfly is the issue.

Gunter,

    I'm running mysql v8.0.19.  Maybe an issue with the msyql jar or a slow database perhaps?

Thanks

You may also check metrics for Writing to the Storage and Receiving from a particular AE. You may have to adjust/extends the default configuration: https://github.com/dcm4che/dcm4chee-arc-light/issues/2066 .
