Query being processed

2) No adapters are visible in the Adapter Monitoring.

I can see only the JPR with Green Status.

3) In the adapter Engine -->Repeat Self-test Status it displays :

Result of Self-Test :

Details for 'Are communication channels without errors?'

0 communication channels have an error status

0 communication channels inactive

0 communication channels not providing any status information

0 adapters logging communication-channel-independent processing errors

I have tried Refreshing the Cache but no change .

How can i resolve this problem?

hi,

It seems that the PI Server is newly installed one.

Have you performed the Post installations steps for PI and have you imported the basis component into the Integration Repository.

For post installation steps you can run the PI Templates

Configuration and installation

Hi,

What is the type of scenario, you are trying to execute.

Check whether the communication channels are active and whether the file has been picked from your source directory.

Also check the error in SXMB_MONI.

Hello Nithiyanandam,

All the adapters are activated .

Iam not able to find any of the adapters in the Communication Channel monitoring.

My scenario is File -->JavaProxy

File is not getting picked from the Source Directory.
