target

Use the target command to configure Post to support a specific type of target. This is known as the target configuration. The properties stored in the target configuration control how Post processes, formats, and outputs replicated data.

The target command also provides options to reset or view target configuration settings.

The target command can be used to control a target configuration both at the global level or, if the queue option is used, at the per-process level.

 

Important: Make certain to stop and then restart the Post process after using this command.

Usage

Supported sources: Oracle
Supported targets: All
Authorization level: Operator (2)
Issues on: target system

Syntax Description

Component Description
{o. | r. | x. | c.}target

The target for which you are configuring Post. The letter preceding the name of the target identifies the type of target, whether an Oracle database, Open Target database, JMS, Kafka broker, file, or change-history target.

Possible targets are:

o.SID

where: SID is the ORACLE_SID of an Oracle database.

r.database

where: database is the name (not the DSN) of an Open Target database.*

x.jms

where: jms is a Java Message Service (JMS) queue or topic.

x.kafka

where: kafka is an Apache Kafka broker.

x.file

where: file is a structured file that contains data in one of the supported formats (see format category).

c.SID

where: SID is the ORACLE_SID of a target Oracle database that is configured as a change-history target.

* Note: The SharePlex-supported datastore types, data types, and operations are listed in the SharePlex Release Notes.

queue queuename

Constrains the action of the command to the SharePlex Post process that is associated with the specified queue. This action overrides any global settings for the target property you are setting. Without the queue option, the target command affects all Post processes in the local SharePlex instance.

Example: the following sets metadata properties for the Post process that is associated with the myjms1 queue.

target x.jms queue myjms1 set metadata time, userid, trans, size

{

set category property |

reset [category [property]] |

show [category] |

switch

}

  • set applies a configuration property to the target configuration.
  • reset clears configuration settings back to their defaults (if one exists). It can be constrained to a specific category and (where applicable) a specific property. Note:reset does not reset one property value to another. Use another set command for that.
  • show displays configuration settings.
  • category is any category of configuration properties. The properties are grouped by category for efficient management through commands. See Category descriptions.
  • property is the configuration property that you want to set, reset, or show. There are different properties per category.
  • switch applies only to file targets (x.file). Use this option to create a new active output file and save the current one as a serially numbered aged file. After issuing this command, the switch occurs after Post processes a new record. This option takes no input and is not associated with any configuration categories.

Descriptions of output formats

The following are descriptions of the output formats provided by format record=record_format.

SQL record format

Every transaction in a SQL-formatted file is headed by a comment that includes the transaction sequence within the SQL file and a unique transaction ID. A comment line at the end of the SQL file has the number of lines in the file. For example, the following is a SQL file with one transaction. In this example the transaction id is 2-113319. The file has nine lines.

/installed/vardir> cat opx/0000000010_20140305140820_legacy.sql

-- 0000000001 2-113319 03052014140813 03052014140813

DELETE FROM "ROBIN"."TEST_TYPES" WHERE ORA_NUMBER = '22345' AND ROWNUM = 1;

INSERT INTO "ROBIN"."TEST_TYPES" (ORA_NUMBER, ORA_DATE, ORA_RAW, ORA_ROWID,

ORA_FLOAT, ORA_CHAR, ORA_VARCHAR2, ORA_TIMESTAMP, ORA_TIMESTAMP_TZ,

ORA_TIMESTAMP_LTZ) VALUES('22345', '08132066000000', '0123456789ABCDEF'

, 'AAAAAAAAAAAAAAAAAA', '12350', 'Character ', 'Variable data'

, '10201998021300.22000', '06172002080000.00000', '06172002160000.00000');

COMMIT;

-- EOF 0000000009

XML record format

The XML format is separated into operation and schema "types" for easier consumption. They are actually the same when viewed from an XSD perspective and are not distinct types. The template XML represents all possible attributes and elements. The individual XML represents the bare minimum output for each supported operation.

After startup, the first time that Post writes a change record for any given table, it first writes a schema record for that table. Each schema record contains the table name and details of interest for each columns. A schema record is written only once for each table during a Post run, unless there is a change to that schema, and then a new schema record is written. If Post stops and starts, schema records are written again, once for each table as Post receives a change record for it.

jms category

Supported targets

JMS

Command options

target x.jms [queue queuename]

{

set jms property=value |

reset jms [property] |

show jms

}

Usage

Sets the properties of a JMS target.

Property Input Value Default

factory_class=factory_class

Required Fully qualified class name of the factory class. Sets the JNDI environmental property java.naming.factory.initial to specify the class name of the initial context factory for the provider.

None

provider_url=url

Required RMI URL with no object name component. This sets the JNDI environmental property java.naming.provider.url to specify the location of the registry that is being used as the initial context.

Use the correct format depending your JMS Provider and type of URL. For example, if using LDAP your URL might be similar to the following:

ldap://hostname.company.com/contextName

Ask your JMS Provider Administrator for the JMS Provider URL.

None

lib_location=path

Required Path to the directory where you installed the client library files.

None

destination={queue | topic}

Messaging domain. Valid values are queue (port-to-port) or topic (publisher-subscriber model).

queue

factory_name=factory_name

Name of a JNDI connection factory lookup. You can specify multiple names with a comma-separated list, for example: (jndi.name1, jndi.name2).

None

user=user

Name of the user that is attaching to JMS. If authentication is not required, omit this and the password option.

None

password=password

Password of the JMS user.

None

queuename=JMS_topic_queuename

Name of the JMS queue or topic.

OpenTarget

persistent={yes | no}

yes logs messages to disk storage as part of send operations.

no prevents logging.

yes
session_transacted ={yes | no}

no directs Post to issue a JMS commit for every replicated message, making each one immediately visible and consumable. This is the default.

yes directs Post to operate in a transactional manner. In this mode, Post issues a JMS commit (to make messages visible and consumable) at intervals based on the following:

  • Issue a commit before the data is read-released from the Post queue, as controlled by the value set for the SP_OPX_READRELEASE_INTERVAL parameter.
  • Issue a commit every JMS write, as controlled by the value set for the SP_OPX_CHECKPOINT_FREQ parameter, until the SP_OPX_READRELEASE_INTERVAL is reached.

no
properties

Use this option if the JMS provider that you are using cannot consume messages that contain the default set of properties supplied by SharePlex. It enables you to remove or add properties. Supply the properties as a comma-delimited list.

  • To add a property, specify it as name=value.
  • To remove a SharePlex property, prefix the name with a dash. For example this string removes two SharePlex properties: -JMSXDeliveryCount,-JMSXGroupSeq.
None
client_id Use this option if the JMS provider that you are using cannot consume messages that contain the default SharePlex client ID. Set this value to the client ID that your provider accepts. None
commit_frequency

Use this option when Post is configured to post to a JMS server in transactional style (issue a JMS commit at intervals, rather than after every message as directed by the session_transacted property). This parameter specifies the interval between JMS commits. It works in conjunction with the SP_OPX_READRELEASE_INTERVAL parameter. Valid values are 1 to any positive integer.

1500
Example

target x.jms set jms queuename=SharePlexJMS

json category

Supported targets

Kafka (format record=json)

Command options

target x. {file | kafka } [queue queuename]

{

set json property=value |

reset json [property] |

show json

}

Usage

Sets the properties of JSON output when format record =json.

Property Input Value Default

before

  • yes includes the before image of the changed row.
    It produces a record similar to the following, with the before image at the end of the line:

    {"meta":{"op":"upd","table":"BILL.JSON"},"data":{"C2":"Bye"},
    "key":{"C1":"1","C2":"Hello"}}
    {"meta":{"op":"upd","table":"BILL.JSON"},
    "data":{"C1":"2"},"key":{"C1":"1"}}
    
  • no excludes the before image of the changed row. It roduces a record similar to the following:

    {"meta":{"op":"upd","table":"BILL.JSON"},"data":{"C2":"Bye"}}
    {"meta":{"op":"upd","table":"BILL.JSON"},"data":{"C1":"2"}}
    

yes

commit

  • yes includes the commit records. It produces a record similar to the following:

    {"meta":{"op":"commit","table":""}}
  • no omits commit records.

IMPORTANT! When commit is set to yes, there can only be one target topic.

yes

ddl
  • yes includes ALTER TABLE commands. It produces a record similar to the following:

    {"meta":{"op":"ddl","table":"BILL.JSON"},
    "sql":{"ddl":"alter table \"BILL\".\"JSON\""}
    
  • No omits ALTER TABLE commands.

yes

eol

yes includes an end-of-line character at the end of the JSON document.

no excludes an end-of-line character.

yes

indent

Controls the level of indentation of the records.

  • A value of 0 places the entire record on one line, as follows:

    {"meta":{"op":"ins","table":"BILL.JSON"},
    "data":{"C1":"1","C2":"Hello ",
    "C3":"There","C4":"2017-03-20T09:46:34",
    "C5":"2017-03-20T09:46:34.735370000"}}

  • A value greater than 0 indents the metadata (if included) and data lines by the specified number of characters.
    It splits the record logically onto multiple lines, as in the following example (indent= 4) :

    {
        "meta":{
            "op":"ins",
            "table":"BILL.JSON"
        },
        "data":{
            "C1":"1",
            "C2":"Hello",
            "C3":"There",
            "C4":"2017-03-20T10:02:37",
            "C5":"2017-03-20T10:02:37.456949000"
        }
    }
    

0

meta
  • yes includes the metadata section of the JSON record. It produces a record similar to the following:

    {"meta":{"op":"ins","table":"BILL.JSON"},
    "data":{"C1":"1","C2":"Hello","C3":"There",
    "C4":"2017-03-20T10:04:44",

    {"meta":{"op":"upd","table":"BILL.JSON"},"data":{"C1":"2"}}
    {"meta":{"op":"del","table":"BILL.JSON"},"data":{"C1":"2"}}
    {"meta":{"op":"commit","table":""}}
    
  • no omits the metadata section and produces a record similar to the following:

    {"data":{"C1":"1","C2":"Hello","C3":"There",
    "C4":"2017-03-20T10:05:09",
    "C5":"2017-03-20T10:05:09.268094000"}}
    {"data":{"C2":"Bye"}}
    {"data":{"C1":"2"}}
    {"data":{"C1":"2"}}
    {}

Note: To specify which metadata fields appear in the record, use the set metadata property command. See metadata category.

Example:

target x.kafka set metadata time,userid,op,scn

yes

schema
  • yes includes schema records.
  • no omits schema records.

    A schema record for objects in replication is produced when a new SharePlex
    configuration is activated or when a table has a DDL change.
    A value of yes (with indent=4) produces a record similar to the following:

    {
        "meta":{
            "op":"schema",
            "table":""
        },
        "schema":{
            "name":"BILL.JSON",
            "utcOffset":"-7:00",
            "C1":{
                "jsonType":"decimal",

kafka category

Supported targets

Kafka

Command options

target x.kafka [queue queuename]

{

set kafka property=value |

reset kafka [property] |

show kafka

}

Usage

Sets the properties of a Kafka target.

Property Input Value Default
broker=broker

Required. The host and port number of the Kafka broker, or a comma delimited list of multiple brokers. This list is the bootstrap into the Kafka cluster. So long as Post can connect to one of these brokers, it will discover any other brokers in the cluster.

localhost:9092
client_id=ID

Optional. A user-defined string that Post will send in each request to help trace calls.

None
compression.code={none, gzip, snappy} Optional. Controls whether data is compressed in Kafka. Options are none, gzip or snappy. None
partition={number | rotate | rotate trans}

Required. One of the following:

  • A fixed partition number: Directs Post to post messages only to the specified partition number. For example, setting it to 0 directs Post to post only to partition 0. This option is suitable for use in testing or if the target has multiple channels of data posting to the same Kafka topic.
  • The keyword rotate: Directs Post to apply messages to all of the partitions of a topic in a round-robin fashion. The partition changes with each new message. For example if a topic has three partitions, the messages are posted to partitions 0,1,2,0,1,2, and so on in that order.
  • The keyword rotate trans: This is similar to the rotate option, except that the partition is incremented with each transaction rather than with each message. For example, if a topic has three partitions, the messages are posted to partition 0 until the commit, then to partition 1 until the commit, and so on in that order. This option is suitable if you are replicating multiple tables to a single topic. It allows you to distribute data across several partitions, while still preserving all of the operations of a transaction together in a single partition. This enables a consumer that reads from a single partition to receive a stream of complete transactions.
0
request.required.acks=value Optional. This is a Kafka client parameter. By default it is set to a value of -1, which means all. Consult the Kafka documentation about this subject, because all really means all in-sync replicas. This parameter can be used in conjunction with the min.insync.replicas broker parameter to tune behavior between availability and data consistency. Important: It is possible for data to be lost between a Kafka producer (SharePlex in this case) and a Kafka cluster, depending on these settings. -1
topic=topic_name

Required. The name of the target Kafka topic.

This string may contain the special sequences %o or %t. The %o sequence is replaced by the owner name of the table that is being replicated. The %t sequence is replaced by the table name of the table that is being replicated. This feature may be used in conjunction with a Kafka server setting of auto.create.topics.enabled set to 'true'. Also view your server settings for default.replication.factor and num.partitions because these are used as defaults when topics are auto created.

Important! If using multiple topics, you must also set the following properties with the target command:

  • The output must be in JSON. Set the record property of the format category to json:

    target x.kafka set format record=json

  • Commits must be disabled. Set the commit property of the json category to no:

    target x.kafka set json commit=no

shareplex

* To avoid latency, if Post detects no more incoming messages, it sends the packet to Kafka immediately without waiting for the threshold to be satisfied.

Example

sp_ctrl> target x.kafkaset kafka broker=host1:9092,host2:9092,host3:9092

sp_ctrl> target x.kafkaset kafka topic=shareplex

Supported targets

Oracle replication targets

Oracle change-history targets

Command options

target {o.SID | c.SID | r.database | x.file | x.jms | x.kafka} [queue queuename]

show metadata

}

Usage

The target command with set metadata can be used to override the default metadata properties that are set for a database target, an XML or JSON file target, a JMS target, or a Kafka target. All of these target types provide metadata in the Post output.

  • Oracle and HANA replication targets: Metadata can be configured for Oracle and HANA replication targets. The metadata columns must exist on the target. SharePlex does not add the metadata columns.
  • Oracle change-history target: If no target specification is made, Post updates the default metadata columns, which must exist in their default names before starting replication. In the following table, the default column names are listed if a property is included in the change-history target by default. Use set metadata only to add additional metadata or to assign a custom name to a column (use the colname option).
  • For targets that support XML input (JMS, Kafka, file) the metadata is formatted per the XML schema. Certain metadata is included in the output by default, as shown in the following table, without the need to use set metadata. Use set metadata only to add additional metadata.
  • For targets that support JSON input (Kafka), the op and table properties are included by default unless you set json meta=no.

For more information about configuring SharePlex to support a change history target database, see the SharePlex Administrator Guide.

To set multiple metadata properties, specify them as a comma-separated list.

Property Value inserted by Post Valid for
time

Time the operation was applied on the source, as supplied by Oracle.

Important! In Oracle version 11g and later, the time appears only in transactional boundary records, for example the start of a transaction. Based on the linear design of both the Oracle redo logs and the way that SharePlex replicates operations in transactional order, SharePlex applies the timetamp contained in the originating record to subsequent records until it encounters a record with a different timestamp.

resources category

Supported targets

All targets

Command options

target {o. | r. | x. | c.} target [queue queuename]

{

set resources property=value |

reset resources [property] |

show resources [for datastore]

}

Usage

Sets parameters that affect resources on the target system.

Property Input Value Default

commit_frequency=number_of_operations

Specifies a maximum number of operations after which Post issues a commit. Can be any integer greater than 1. Can be used to divide a large transaction into two or more smaller ones, each containing, at most, the specified number_of_operations. This option can work around resource limits that affect large transactions, such as the number of row locks permitted per transaction.

50000

max_active_statements=number_of_cursors Specifies the number of concurrent active SQL statements that Post can process to a target database in one session. Can be any integer up to, and including, the maximum number of active statements permitted by the database or client driver. It is only used by Post when the SP_OPX_SQL_CACHE_DISABLE parameter is set to 0 (enabled).

16

Examples

target r.mydb queue q1 set resources commit_frequency=10000

target r.mydb queue q1 set resources max_active_statements=10

target r.mydb show resources for teradata

rule | filter category

Supported targets

Oracle change-history target

Command options

target c.SID [queue queuename]

table tablename

{

set {rule | filter} { 'column_condition' | !filename }

reset {rule | filter}

show {rule | filter}

}

Usage

Specifies a conditional statement that applies a tracking rule or filter to a specific table. Applies to UPDATE operations. Applies conditional logic that qualifies the data that you want to track to a target table, while excluding data that is not of interest. There can be one rule or filter per target table, but you can combine nested expressions with parentheses and the AND, OR, and NOT logical connectives to create a wide variety of conditions.

Syntax element Description
rule | filter
  • rule directs Post to insert a row only if the UPDATE operation matches the column_condition. If the UPDATE does not match the column condition, the row is discarded.
  • filter directs Post to insert a row only if the UPDATE does not match the column_condition. If the UPDATE does match the column condition, the row is discarded.
table tablename The name of the target table for which you are setting the rule or filter.

column_condition

The conditional logic that must be satisfied by the UPDATE operation. column_condition represents the entire conditional statement, which must be enclosed within single quotes. A column condition can be one or any combination of the following expressions, each enclosed within parentheses:

(column is changed)

(column is not changed)

([column1, column2, ...] matches change_list)

([column1, column2, ...] contains change_list)

 

Where:

  • column is the name of a target column. Use a comma to separate column names in a list, and enclose a list within brackets.
  • is changed means that the specified column(s) are changed in the UPDATE operation.
  • is not changed means that the specified column(s) are not changed in the UPDATE operation.
  • change_list is a logical representation of the source columns that changed.
  • matches change_list is satisfied when the condition is an exact match to the change list (no fewer columns than the change list, no more columns than the change list, same names).
  • contains change_list is satisfied when the condition contains all of the columns in the change list. The change list can be a subset of the columns in the condition, but it cannot contain more columns than the change list. Names must match.
!filename Enables you to store a large column condition in a text file, and then specify the file, rather than the entire column condition syntax, when you run the target command.

Note: Batch and direct load operations are not supported by the rule/filter feature.

Examples

These commands show some examples of how to set different rules by combining expressions:

target c.mySIDtable mytable set rule '(col3 is not changed) and (col5 is not changed)'

target c.mySIDtable mytable set rule '([col1, col3] matches change_list)'

target c.mySIDtable mytable set rule 'not ([col2, col5] contains change_list)'

 

The following table shows the different ways that rule and filter work to include or discard rows.

Rule Updated columns Row inserted?
rule = '(c2 is not changed)' c2 no
rule = '(c2 is not changed)' c3 yes
rule = '(c2 is changed)' c2 yes
rule = '(c2 is changed or c4 is changed)' c1 no
rule = '(c2 is changed or c4 is changed)' c1,c3,c5 no
rule = '(c2 is changed or c4 is changed)' c2 yes
rule = '(c2 is changed or c4 is changed)' c3,c4,c5 yes
rule = '([c3,c6,c7,c8] matches change_list)' c3,c6,c7,c8 yes
rule = '([c3,c6] matches change_list)' c3,c6,c7 no
rule = '([c3,c6,c7] contains change_list)' c3,c6 yes
rule = '([c3,c6] contains change_list)' c3,c8 no
     
Filter Updated columns Row inserted?
filter = '(c2 is not changed)' c2 yes
filter = '(c2 is not changed)' c3 no
filter = '(c3 is changed and c4 is changed)' c1 yes
filter = '(c3 is changed and c4 is changed)' c3,c4 no
filter = '(c3 is changed and c4 is changed)' c1,c2,c3 yes
filter = '([c3,c6,c7] matches change_list)' c3,c6 yes
filter = '([c3,c6,c7] matches change_list)' c3,c6,c7 no
filter = '([c3,c6] contains change_list)' c3,c6 no
filter = '([c3,c6,c7] contains change_list)' c3,c8 yes

source category

Supported targets

Oracle change-history target

Command options

target c.SID [queue queuename]

{

set source sourceID |

reset source |

show source

}

Usage

Sets the user-defined source identifier for the SHAREPLEX_SOURCE_ID metadata column. Use target with the set metadata source option to configure Post to populate this column. Specify any single alphanumeric string.

Example

The following shows the use of set source to support a configuration where the data from multiple source databases is being replicated to the same target database. This target configuration causes each Post process to update the SHAREPLEX_SOURCE_ID column with a different source ID, depending on the source database, to differentiate the data in the target database. This example uses four Post processes.

target c.target1 queue source718 set source east

target c.target1 queue source92 set source south

target c.target1 queue source101 set source west

target c.target1 queue source75 set source north

The Post process for queue “source718” will update column SHAREPLEX_SOURCE_ID with the value "east" for every insert or update to a table in its stream. The Post process for queue "source92" will update column SHAREPLEX_SOURCE_ID with the value "south", and so on for the other two Post processes.

sql category

Supported targets

File (format record=sql)

Command options

target x.file [queue queuename]

{

set sql property=value |

reset sql [property] |

show sql

}

Usage

Sets the properties of SQL output when formatrecord=sql.

Property Input Value Default

add_rownum={yes | no}

yes to include or no to exclude row numbers

yes

begin_transaction={yes | no}

yes to include or no to exclude begin transaction records

no

comment=character

Character that marks a comment

--

concatenate=character

Character that concatenates strings

||

end_transaction={yes | no}

yes to include or no to exclude end transaction records

no

legacy={yes | no}

Required in SharePlex 8.6. Use legacy SQL date and timestamp format of:

MMDDYYYYHH24MISS and MMDDYYYYHH24MISS.FFFFFF(yes/no)

no

name_delimiter=character

Character that delimits SID, table, owner, column names. This value overrides the value that is returned when Post queries the ODBC driver for the setting of SQL_DELIMITER.

none

record_terminator=character

Character that terminates the SQL

;

Example

target x.file set sql comment=#
