Recently i upgraded my SAP(Oracle+Win2k) kernel 7.01 Patch Level 23 to Patch Level 150 via JSPM . After upgrading however i am able to start SAP by MMC,  SAP Dispatcher is running but I am not able to see my ABAP WP table. Dispatcher turns to yellow and shows “Dialog info queue unavailable“. After some research i am able to solve out the issue.

Procedure to resolve:

The sapstartsrv.exe file is not updated in C:WINDOWSsystem32. (after kernel upgrade)

The resolution is to copy the latest file from /SID/exe of the upgraded kernel and paste and overwrite the one existing in C:WINDOWSsystem32 and then restart the Services and SAP.

The dialog queue appeared and the issue resolved.

Hope this helps..
