同事反應說SAP掛了，進去SAP，SM51發現Update is deactivate!並出現很多Update Dealy！趕緊SM12 F5激活，但兩秒後又是Update is deactivate!怎麼回事？
再DB02查一下，critical tables/indexs ，艹！果然是有index: CDCLS 等無法擴展了,再SM21查system log,
Database error 1654 requires intervention by the database administrator
The connection was de-activated after a DB error
Update-request restarted after internal error.
The update was activated
Database error 1654 requires intervention by the database administrator

所以，先加PSAPCLUI表空間，再activate Update. 一切正常！
