Starting and Setting Up RTR 2.12 How RTR Selects Processing-states (Roles) for Nodes 2.12 How RTR Selects Processing-states (Roles) for Nodes This section discusses how RTR assigns roles to backend node partitions, and how routers are selected.
Starting and Setting Up RTR 2.12 How RTR Selects Processing-states (Roles) for Nodes The SHOW P ARTITION command on each backend node is as follows: Backend partitions on node BRONZE in group "te.
Starting and Setting Up RTR 2.12 How RTR Selects Processing-states (Roles) for Nodes 8. The network connection to node Gold is reestablished. The partition on Gold retained its original sequence number of 2 and retains the primary role while the partition on Bronze reassumes the secondary role.
Starting and Setting Up RTR 2.12 How RTR Selects Processing-states (Roles) for Nodes Router Site A Site B Node-A1 Node-A2 Node-B1 Node-B2 If the relative priority (sequence number) for Node-A2 is chan.
Starting and Setting Up RTR 2.12 How RTR Selects Processing-states (Roles) for Nodes relevant to a backend. It is where the backend goes to obtain and verify partition configuration and facility information. Routers are made known to the frontend systems through the list specified in the /ROUTER=(list) qualifier to the CREA TE F ACILITY command.
3 Partition Management 3.1 Overview This section describes the concepts and operations of RTR’ s partitions. 3.1.1 What is a Partition? Partitions are subdivisions of a routing key range of values. They are used with a partitioned data model and RTR data content routing.
Partition Management 3.2 Partition Naming 3.2 Partition Naming A prerequisite for partition management is the ability to identify a partition in the system that is to be the subject of management commands. For this purpose, partitions have been given names, which may be drawn from a number of sources described below .
Partition Management 3.3 Life Cycle of a Partition 3.3.1 Implicit Partition Creation Partitions are created implicitly when an application program calls rtr_open_channel( ) to create a server channel, specifying the key segments and value ranges for the segments with the pkeyseg argument.
Partition Management 3.5 Entering Partition Commands 3.5 Entering Partition Commands Partitions can be managed by issuing partition commands directed at the required partition after they are created.
Partition Management 3.5 Entering Partition Commands The rtr_set_info( ) call completes asynchronously . If the function call is successful, completion will be signaled by the delivery of an RTR message of type rtr_mt_closed on the channel whose identifier is returned through the pchannel argument.
Partition Management 3.6 Managing Partitions 3.6.2 Controlling T ransaction Presentation T ransaction presentation is the process of passing transactions to idle server channels for processing. While transaction presentation is active, new transactions are started on the first free server channel for the appropriate partition.
Partition Management 3.6 Managing Partitions If a partition enters a wait state or fails but has neither a local or remote journal, an operator can instruct RTR to skip the current step in the recovery process with the /IGNORE_RECOVERY qualifier .
Partition Management 3.6 Managing Partitions 3.6.4.2 Programming Information T o set the partition backend priority list, program the set_qualifier argument of the rtr_set_info( ) call as follows: rtr_qualifier_value_t set_qualifiers[ 2 ]; char *szNodeList = "your,list,of,node,names,here" set_qualifiers[ 0 ].
Partition Management 3.6 Managing Partitions • rtr_partition_fail_to_shadow • rtr_partition_pre32_compatible 3.6.6 Controlling T ransaction Replay RTR has implemented the capability of controlling transaction replay in cases where a "killer message" happens during a transaction replay preventing recovery from continuing normally .
Partition Management 3.7 Displaying Partition Information 3.7 Displaying Partition Information Information on the definition and state of a partition is displayed with the SHOW PARTITION command. The information of interest in the context of partition management relates to the backend instance of the partition.
4 T ransaction Management 4.1 Overview This section describes the concepts of RTR’ s transaction management capability . The RTR transaction is the heart of an RTR application, and transaction state is the property that characterizes a transaction’ s current condition.
T ransaction Management 4.1 Overview this transaction is removed from memory and can no longer be monitored by the command. The RTR DUMP JOURNAL command can be used to trace and review the flow of a transaction.
T ransaction Management 4.1 Overview 4.1.2 T ransaction State Changes There are eight valid state changes allowed for the SET TRANSACTION command. Attempting to change transaction state to a state that is not allowed produces an error message of %RTR-E-INVSTATCHANGE, Invalid to change from current state to the specified state .
T ransaction Management 4.1 Overview This is the case where, for example, a server crashed while performing an SQL commit immediately after receiving a mt_accepted message. The transaction is in COMMIT state as recorded in the RTR journal and the transaction is also committed in the underlying database.
5 RTR Monitoring This chapter contains a description of the RTR monitor . The RTR monitor gives you a means of viewing the activities of RTR and your applications. Many different aspects of RTR’ s behaviour can be viewed, allowing the activities and performance of RTR to be analyzed.

Server Shadowing and Recovery B.2 Automatic Features • RTR_EVTNUM_SRSHADOWGAIN - Server has gained its shadow partner • RTR_EVTNUM_SRRECOVERCMPL - Server has completed recovery The shadow events are delivered with no special status and no data. They are delivered only to the server(s) whose state has changed.
Server Shadowing and Recovery B.3 The RTR Journal System The number of blocks specified by the /BLOCKS qualifier specifies the size of the journal that RTR attempts to keep to. (The actual number of blocks used may vary , depending upon the load on RTR.
Server Shadowing and Recovery B.4 Shadow Site Failure and Journaling B.4.1 Maximum Journal Size The current maxima for the size of a journal are: Number of blocks per disk: 524288 (This is max_segments_per_disk * disk_blocks_per_segment , or 16384 times 32.
Server Shadowing and Recovery B.6 Performance Note that RTR does not have to wait for the secondary shadow server to complete its processing. It only needs to know that the primary has committed the transaction and that the journal file of the secondary shadow server contains the final vote status.
