Hi,
Reason of this error is :
During J2EE Engine restart the CPA Cache application tries to read the configuration data from the Integration Directory. The Integration Directory is an application, whereas the the CPA Cache is an J2EE service and starts earlier. Therefore the automatic delta cache refresh fails on the central AE in case of a server restart and the CPADirectoryCacheException is thrown.
This exception can be ignored. The CPA service stores its cofiguration data in the database. During J2EE Engine downtime the Integration Directory is not available either. Therefore no new configuration can be added in the Integration Directory and there and the system has a consistent state after restart.
The automatic delta cache refresh mechanism is necessary for decentral Adapter Engines, after system restart. During a downtime of a decentral Adapter Engine the configuration data in the Directory can change, since it runs on different physical machine.
An inconsistency can only arise under special circumstances on a central Adapter Engine: The Directory data is changed while the CPA Cache service is down (an error is reported in the Directory's Cache notification). Engine restart will not update the CPA Cache data, due to the above explained reason.
and solution of this problem is
Restart the CPA Cache application "com.sap.aii.af.cpa.app" manually. This can be done with the Visual Administrators "deploy" service. Make sure that the Integration Directory is available. The Directory's Cache notification should report success after that.Alternatively you can trigger a partial (delte) cache refresh.
Also try this solution.
In Release 6.40 you can use adapter metadata from SAP BASIS 6.40 only. If, regardless of this, you import the content of SAP BASIS 7.00, the 6.40 adapter metadata in the cache is overwritten. As a consequence, objects cannot be loaded at runtime and messages trigger an error.
The adapter metadata from the software component SAP BASIS 7.00 is not distributed to the runtime cache.
The communication channels with adapter types from SAP BASIS 7.00 can no longer be activated.
1) Import the archive as described in the Support Package Stack Guide.
The correction concerns the archive:
For XI 30 SP18:
- SAPXITOOL18P_2.sca
For XI 70 SP09:
- SAPXITOOL09_3.sca
The archive and the Support Package Stack Guide are located on the SAP Service Marketplace. See Note 952402 for the relevant link.
2) Execute a complete cache refresh for the adapter engine.
Note: Bear in mind that if you created communication channels with the adapter types from SAP BASIS 7.00, these will not work in Release 6.40. Therefore, you must change the channels that they use the relevant adapter type from SAP BASIS 6.40 and activate the changed channels.
Hope this will help you.
