two entries for every technical system for XI in SLD

[Former Member]

Hi,

Last weekend we had a patch upgrade in our Production env for SAP PI system.

After that we got the Cache error (Cache notification from Integration Directory failedError when accessing the System Landscape Directory) in RWB -- "Cache Connectivity Test -> IR -> ID -> Adapter Engines".

And

In SLD->Technical Systems->all (Adapter Engine, Integration Directory, Integration Repository, RWB).

e.g.:There are two Adapter Engines:

Adapter Engine on p80.p80xxxxx

and

Adapter Engine on p80.p80xxxxx\p80

Our Basis team contacted SAP for help & SAP has suggested as below.

"We compared the SLD->Technical Systems for QA (Q80) and PROD (P80), and found that for the production box (P80), each XI component is registered Twice. Now as per the note 764176, we have to delete the entries in the SLD -> Technical Systems. And these will be re-created after a restart. Could you please let us know whether these have been maintained for any special reason or we can go ahead and delete them."

If you have any idea if those two should be maintained or not, please suggest how to proceed.

Thank you & Best regards,

Farooq.

Hi Farooq,

I have faced the same issue and got resolved by 764176.

you can go ahead and implement the note 764176 which will resolve your issue.

You should have just one entry. If you have two entries for Adapter Engine, also ensure to apply the note 804124 before performing the self-registration again as per note 764176, this will prevent the AE from being registered twice or with wrong host.
