6 Synchronization Process
This section describes the synchronization process in chronological order during the backup of the shipboard database in the current state, and then restores the backup to the QCI Shore Database. The process differs if TDE is applied. See process listed in Table 6-2.
Table 6-1 Synchronization Process For Non TDE Database
Process | Description of Synchronization Tasks |
---|---|
Process 1 |
Performs the ship’s database first backup routine on database schema only. The backup file refers to "QCISHORE.dmp.2". |
Process 2 |
After the first backup routine completes, the interface then drops the QCI Shore database “UID” object and then the BKSTG_DINING” user. The interface waits for approximately 120 seconds for the QCI Shore database user "UID" to disconnect before the backup process begin. |
Process 3 |
The interface creates all necessary triggers (TRIGGER_NAME like ‘TR_QCI%’) on the ship database for Offline Mode enabled. At this point, the ship database Offline Mode status change to "Enabled". All reservation changes made on the ship database from this point are updated to the CHG table for synchronization at a later stage. |
Process 4 |
Perform ship’s database second backup routine on database data and it excludes some non-required tables such as POS, MIB, and others. The backup file refers to "QCISHORE.dmp.1". |
Process 5 |
Perform ship’s database third backup routine that only contains VIS data and XDOC data without blog contents. The third backup file name is QCISHORE.dmp.1.VIS and QCISHORE.dmp.1.XDOC. |
Process 6 |
Perform ship’s database forth backup routine on BKSTG_DINING user data if user BKSTG_DINING exists in the ship database. The forth backup file name is QCISHORE.dmp.3. |
Process 7 |
At the end of the ship database data backup routines, the command prompt window shall close automatically. |
Process 8 |
Perform the first (1st) database restore routine on “UID” database data. (filename=QCISHORE.dmp.1). During the restore routine, the command prompt window opens, showing the restoration progress and closes when the process completes. |
Process 9 |
Perform the second (2nd) database restore routine on “UID” data table VIS and XDOC (filename=QCISHORE.dmp.1.VIS and QCISHORE.dmp.1.XDOC). During the restore routine, the command prompt window opens, showing the restoration progress and closes when the process completes. |
Process 10 |
Perform the third (3rd) database restore routine on “UID” database structure (filename=QCISHORE.dmp.2). During the restore routine, the command prompt window opens, showing the restoration progress and closes when the process completes. |
Process 11 |
After completing all the restorations on the “UID” schema, the interface performs the forth database restore routine for user "BKSTG_DINING" data to the QCI Shore Database. (filename= QCISHORE.dmp.3). This process only applicable when the "Backup and Restore Silverwhere Schema" is selected. |
Process 12 |
After the database restoration completes, the interface then updates the last backup date and time to the QCI Shore database parameter “QCI Offline DB Backup Date” and “QCI Offline DB Backup Date Server”. For example, 20090306172359. |
Process 13 |
All guests in the QCI Shore database are checked out if the checkbox “Check Out Guest in Offline DB after Backup and Restore” is selected in the Settings tab. |
Process 14 |
If option “Automatic move actual posting to route account during sync” is checked, when user enabled the routing at shore-side database, the posting and payment auto route to the payer when routing information is sync to ship database. If option “Automatic move actual posting to route account during sync” is deselected, when user enabled the routing at the shore-side database, only the routing information syncs to ship’s database. The program allows routing the posting and payment to payer while synchronizing the routing information from shore to ship. |
Process 15 |
Creates all necessary triggers and sequences and then disable all interfaces such as PBX, ITV, DR, VIP, ADPI and Door Lock Interfaces parameters in the QCI Shore Database. |
Process 16 |
The QCI Shore database offline mode is "Enabled" and the message “SPMS DB already ready with offline embarkation” appears in the Messages tab. |
Process 17 |
The system prompts a QCISync dialog box indicating the system is ready for Offline Mode and the server can be taken offline, ready to be taken into the terminal. Click OK to close the dialog box. |
Synchronization Process for DB Using TDE
The synchronization process for a database that uses TDE are lesser from the standard process, and are listed in below table.

Table 6-2 QCI Synchronization Process for DB Using TDE
Process | Description of Synchronization Tasks on DB using TDE |
---|---|
Process 1 |
The interface drops the QCI Shore database |
Process 2 |
The interface creates all necessary triggers (TRIGGER_NAME like ‘TR_QCI%’) on the ship database for Offline Mode enabled. At this point, the ship database Offline Mode status changes to "Enabled". All reservation changes made on the ship database from this point are updated to the CHG table for synchronization at a later stage. |
Process 3 |
QCI Shore database performs the first database import routine
on |
Process 4 |
QCI Shore database performs the second data import routine
on |
Process 5 |
QCI Shore database perform the third data import routine
on |
Process 6 |
After completing all the restoration on |
Process 7 |
After the database restoration completes, the interface then updates the last backup date and time to the QCI Shore database parameter, “QCI Offline DB Backup Date” and “QCI Offline DB Backup Date Server”. For example, 20090306172359. |
Process 8 |
All guests in the QCI Shore database are checked out if the checkbox “Check Out Guest in Offline DB after Backup and Restore” is selected in the Settings tab. |
Process 9 |
If option “Automatic move actual posting to route account during sync” is selected, when the user enables the routing at the shore-side database, the posting and payment auto route to payer when routing information is synchronized to the ship database. If the “Automatic move actual posting to route account during sync” option is deselected, when the user enables the routing at shore-side database, only the routing information is synchronized to the ship database. Program allows routing the posting and payment to payer while synchronizing the routing information from shore to ship. |
Process 10 |
Creates all necessary triggers and sequences and then disable all interfaces such as PBX, ITV, DR, VIP, ADPI and Door Lock Interfaces parameters in the QCI Shore Database. |
Process 11 |
The QCI Shore Database offline mode is "ENABLED" and the message, “SPMS DB already ready with offline embarkation” appears in the Messages tab. |
Process 12 |
The system prompts a QCISync dialog box indicating the system is ready for Offline Mode. Click OK to close the dialog box. |
Process 13 |
The system disables all parameters in the Settings tab and a dimmed ‘Locked’ is shown on the window when the Offline Mode is ready. |
Below are some examples of records that were added from the QCI Shore database to the ship database or vice versa.
-
The system indicates the number of remaining records to process, update, or skip during synchronization in the Messages tab.
Figure 6-2 Quick Check In Synchronizer
-
The synchronization processes five pictures data (SEC records) per batch and is only applicable when adding new SEC records from Shore to Ship. Messages shown in the Messages tab are ‘x value Update to Ship DB' when updating of SEC from shore to ship and 'Adding new record to shore' when a new record is added in Ship DB and transferred to shore DB. Any changes made to the SEC table from the ship do not transfer to the Shore Database.

The QCI Sync process excludes the data below by default when synchronizing the shipboard database to the offline database:
-
Fleet Management System (FMS) data
-
Material Management System (MMS) data
-
Payroll data such as ADC, ADP, ADS, ADT, ADU, COH, COS, CTR, CTT, DDT, DPL, PAY, PCY, PGD, PGE, PGL, SED, SGT, SLB, SPD, SPO, SPP, SPT, SSH.
-
ResOnline data and Crew Management System (CMS) data such as RSP, RSL, RSD, FCCMSMSGS, CMSCHG, CMSRSL, CMSRSP, CMSRSD, FMS_TRANSFER, CHG_MOBILE_IN, CMS_UPL, CMS_UPL_RSP.
-
Data from table starts with ‘X’ for example, XAPP, XCET, XCTY, XDET, XMVW, XPDF, XSCP, XTIM, XUAF, XUSP, XUSR, XUST, XVEN, XDOC, with the exception of XDOC_GROUP < 12
-
-
The QCI Sync does not synchronize the credit card (CCA) records to an offline database. When obtaining the credit card in an offline mode, the QCI Sync Interface checks if the parameter Card Interface Name is Enabled in the ship database. If it is, the CCA record is created in the ship database. Otherwise, the Synchronization interface only synchronizes the credit card registration (CRD) record.
-
When the QCI Shore Database server is ready for transfer from the ship to the terminal, the IT Officer will shutdown the QCI server and relocate the server to the terminal for embarkation preparation.
-
When the QCI Shore Database server is down, the interface for QCI Shore Database status will indicates as “Disconnected” and the message “Shore QCI DB is offline, cannot sync” appears in the Messages tab. The message “Resetting connection” indicates the interface continue to check and attempt to reconnect to the database. This is due the interface application were not running or closed without pressing the Stop Offline Mode
-
After transferring the QCI Shore Database server to the terminal, start it up and connect to the shore network. The Shore QCI Database Status changes to ‘Connected’ within a few minutes. If the terminal does not have network access to the ShipDB, the IT Officer is required to shut down the Shore QCI database server and transfer the server back to the ship at the end of the pier embarkation, before connecting the shore Offline Database Server to the shipboard network.
The QCI Sync Interface starts the synchronizing of the ship and shore QCI database once a connection is established.
