28 | introducing status management: The processing per subdetector is divided into several steps, | |
29 | after each step the status is stored on disk. If the system crashes in any of the steps the Shuttle | |
30 | can keep track of the number of failures and skips further processing after a certain threshold is | |
31 | exceeded. These thresholds can be configured in LDAP. | |

60 | // | |
61 | // This class is a wrapper of AliDCSMessage. | |
62 | // These are the messages which form AliDCSProtocol. | |
63 | // Every message has header and body. The body size is written in the header. | |
64 | // There are five message types: | |
65 | // 1) Request - used by the client to form a single request to DCS server | |
66 | // 2) Count - returned by the server to inidicate the total number of | |
67 | // values which would be sent to the client. | |
68 | // 3) ResultSet - returned by the server and contains part of values set | |
69 | // which forms the server resposen. | |
70 | // 4) Error - returned by the server in case of error | |
71 | // 5) MultiRequest - used by the client to form multi request. | |
72 | // This is a request which serves many aliases/dp at the same time | |
73 | // For all aliases/dp the same time interval is used. | |
74 | // Short description of the schema: | |
75 | // The client sends a request (Request or MultiRequest) and the server | |
76 | // returns: | |
77 | // 1) Count - the total number of values that the client should | |
78 | // expect. | |
79 | // 2) ResultSet* - every ResultSet message contains a part | |
80 | // of valueSet (some values) which the client should expect | |
81 | // The client can wait for ResultMessage until it gets | |
82 | // all values (total number) which was returned by the | |
83 | // Count message at the beginning of the ResutlSet sereie. | |
84 | // In case of error: | |
85 | // 1) Error - contains the error code and error description | |
