Can't refresh CPACache,Cache errors,no adapters listed in Adapter monitorin

[Former Member]

Hi All,

we have installed PI 7.0 SP12. Dev system is working fine. In quality system, in the adpater monitoring we can only see the JPR adapter <b>but no other standard adapters (FILE, JDBC etc) are displayed</b>. No Communication Channel shows up in Communication Channel Monitoring.

We can select adapters during creating a communication channel in Integration directory. (we <b>imported the adapter meta-data</b> into IR, SAP BASIS SWCV 7.0, <b>re-imported</b> also)

<b>We have followed "How to Handle Caches" guide step by step</b> and getting error in the following tests (Everything else looks fine):

1) Tring to refresh the CPA Cache (Using the right URL and right user PIDIRUSER to login)

Results: <b>Never able to refresh CPA Cache</b>. We are getting following errors in CPACache history:

<?xml version="1.0" encoding="UTF-8" ?>

2) Checking the Cache Notification Status/Checking the Cache Update Status

Integration Directory --> Choose Environment --> Cache Notifications….Problem Tab

Results: In the Problem tab we have erros for all communication channels:-

3) Cache Connetion Test

Runtime Workbench --> Component Monitoring --> Choose Display --> Cache Connectivity Test --> choose Start Test.

Results: All the components are green accept Central Adapter Engine. For Central Adapter Engine we are getting following error/warning:-

<b>Attempt to fetch cache data from Integration Directory not yet started or still in process</b>

Please let us know if anyone has idea how to resolve above problems.

Dear Janga,

I managed to solve this kind of issue by increasing the number of server process of JCO RFC providers.

Generally 503 Service unavailable comes when server process unable to handle the load and services are busy serving for huge number of concurrent requests.

Shanaka.

Indrasena,

Which user you are using while calling the URL? Use XIAFUSER. Also check whether the XIAFUSER is locked ?

Hi Raj,

Thanks for quick reply. Well I think you use PIDIRUSER to carry out a CPA Cache refresh not XI/PIAFUSER. No service user is locked.

Hi All,

Please refer SAP " <b>Note 1057882 - XI 3.0 SP20 / PI 7.0 SPS12: Full CPACache refresh is stuck</b>".

Symptom

The full CPA Cache update is stuck and does not finish.

Reason and Prerequisites

The problem described above may only occur for the XI 3.0 SP 20 and PI 7.0 SPS12 releases.

Solution

The described problem is solved with

patch 02 of Support Package 20

of the XI ADAPTERFRAMEWORK CORE 3.0 software component.

and patch 01 of Support Package 12

of the XI ADAPTERFRAMEWORK CORE 7.0 software component.

The archives and the support package stack guide can be found on the

services marketplace as described in SAP Note 952402.

Thank You,

Indrasena Janga
