[APM 9.40] BPM 9.51 Installation "Failed to register BPM Agent - Invalid digital signature"

Hello,

we have successfully installed BPM 9.51 on an APM 9.40 infrastructure.

After creating the BPM instance we get the error http 440 from the BPM Web interface with the message "Failed to register".

We checked also the BPM logs (bpm_all.log and bpm_bsm_comm.log) and we found these error messages:

 

ERROR [DefaultQuartzScheduler_Worker-12] [AbstractBsmApi] Failed to register instance INSTANCENAME
java.lang.Exception: [registerAgent] Failed to register the agent. hostName=HOSTNAME The thrown message is: (java.lang.Exception) Failed to register BPM Agent. Agent Name: AGENTNAME  - Invalid digital signature.

	at org.quartz.core.JobRunShell.run(JobRunShell.java:213) [quartz-all-2.1.1.jar:?]

 

 

We tried the following workarounds:

  • Delete and recreate the keys:

- Stop BPM;

- Remove the private and public keys;

- Start BPM;

  • Delete the public key using the JMX console from the gateway server using the operation "removePublicKey";

 

  • Uninstall BPM 9.51 and install it again;

 

None of these solutions worked for us.

Looking forward to any hint on this issue.

Thanks in advance,

 

Paolo

You can disable digital signature via Infrastructure Settings > Foundations: EUM Administration > Disable BPM Authentication

Re: [APM 9.40] BPM 9.51 Installation "Failed to register BPM Agent - Invalid digital signature

Hello Asaf,

thanks for you reply.

We saw that solution in other posts, however we decided to not use it: we have already installed BPM9.51 on other servers without any issue and this change would affect all the servers.

Could you please give us more details about the option "Disable BPM Authentication"? As stated before, there are other BPM machines which are successfully registered so we are concerned about possible bad outcomes from the change.

Thanks,

Paolo

It won't impact the already registered BPMs.

Re: [APM 9.40] BPM 9.51 Installation "Failed to register BPM Agent - Invalid digital signature

Hi Asaf,

on APM DB in the table EUMBPM_HOSTS we noticed that the column "PUBLIC_KEY" is "(null)"  for the server that is failing to register.

We checked on the BPM server and both public and private keys have been created, so it seems APM is failing to update the DB.

When we tried to invoke RemovePublicKey from JMX Console the field "MODIFIED_TIME"  was updated accordingly. However the field "PUBLIC_KEY" did not change.

What could be the cause?
