sdsGetSecondaryProxy
sdsGetSecondaryProxy(name: String; proxy: JadeDynamicObject input);
The sdsGetSecondaryProxy method of the JadeDatabaseAdmin class, valid only at the primary database system, creates and populates an SDSSecondaryProxy object for the secondary system or RPS node specified in the name parameter and returns the secondary or RPS proxy dynamic object in the proxy parameter.
The SDSSecondaryProxy object returned by the sdsGetSecondaryProxy method contains a subset of the SDSSecondary dynamic object attributes, including nextJournalNumber.
The secondary or RPS proxy object:
-
Enables you to obtain summary information about a secondary or RPS node without having to go to the secondary or RPS node.
-
Can be called when the secondary or RPS node is disconnected.
You should call this method to first get a secondary or RPS proxy object and check the connectionState attribute value before calling the sdsGetSecondaryInfo method.
Use this method in conjunction with the JadeDatabaseAdmin class getCurrentJournalOffset method to determine the amount of journal data that has not been sent to the secondary.
The SDSSecondaryProxy dynamic object has a JadeDynamicObject class name attribute value of SDSSecondaryProxy and type attribute value of SDS_SecondaryProxyType (2).
The dynamic attributes that are returned are listed in the following table.
Name | Type | Description |
---|---|---|
connectionCheckInterval | Integer | Number of seconds at which the secondary database or RPS node polls the primary to determine reachability via the communication paths, specified in the |
connectionState | Integer | State of the connection to the primary |
hostName | String | Computer name of the secondary or RPS proxy host on the primary |
lastErrorCode | Integer | Number of the last error that occurred |
myName | String | Name of the secondary or RPS proxy on the primary, specified in the |
nextJournalNumber | Integer | Next journal the primary sends if the secondary or RPS node is catching up or the next write journal when the secondary or RPS node is mirroring writes from the current journal. It remains valid when the secondary or RPS node is disconnected. |
primaryServerName | String | Name of the primary, specified in the |
subrole | Integer | Database role |
syncMode | Integer | Mode of journal synchronization, specified in the |
totalSends | Integer64 | Count of messages sent to the secondary |
totalBlocksSent | Integer64 | Count of journal blocks sent to the secondary (there can be from 1 through 16 blocks per message) |
totalBytesSent | Integer64 | Count of bytes sent to the secondary; that is, the total size of all messages sent |
totalUncompressedBytes | Integer64 | Count of bytes sent to the secondary if compression was disabled |
lastRecordSentJournal | Integer64 | Journal number of the last journal record sent |
lastRecordSentOffset | Integer64 | Byte offset of the last journal record sent |
The values of the subrole attribute are represented by one of the
Global Constant | Integer Value | Description |
---|---|---|
SDS_SubroleNative | 1 | Native JADE Object Manager database |
SDS_SubroleRelational | 2 | Relational database |
The values of the syncMode attribute are represented by one of the
Global Constant | Integer Value |

SDS_BlockWrite | 2 |
SDS_JournalSwitch | 1 |
The caller is responsible for deletion of these transient dynamic objects. Deletion is best achieved by purging the object when the entry has been processed.
