Alphabetical reference for SharePlex commands

Alphabetical Reference for SharePlex Commands

This starts the detailed reference documentation for SharePlex commands in alphabetical order.

abort config

Use the abort config command to deactivate a configuration instantly and delete all associated queues and replication processes at the same time. This command stops all replication activity for the configured datasource on the source and target systems, whether or not data in the queues has been posted. It is a forceful deactivation.

The abort config command is effective when there has been a system, configuration, or data problem and you need to prevent posting to the target system(s). Because you are deleting whatever data remains in the pipeline, the source and target instances will go out of synchronization after this command takes effect.

If any SharePlex replication process stops before or during the abort config command, the command also stops. When the process starts again, the command resumes working. This allows abort config to work even if the network is temporarily down — it remains in the queues until the connection is restored.

If there are multiple active configurations on the same source system, use the abort config command only if there are named export queues that separate the replication streams for each one. Without named export queues, SharePlex funnels all replicated data through one export queue, and an abort config command for one configuration deletes the data for all of them. To create named queues, see Chapter 5 of the SharePlex Administrator’s Guide.

Usage

Supported sources:

Oracle

Supported targets: All
Authorization level: Administrator
Issues for: source system
Related commands: deactivate config, purge config

Syntax

Basic command Remote options
abort config filename

[ on host |

on host:portnumber |

on login/password@host |

on login/password@host:portnumber ]

Syntax description
Component Description
filename 

The name of the configuration that you want to abort. Configuration names are case-sensitive.

Example:

sp_ctrl(sysA)> abort config sales

Remote options

These options enable you to issue the command on a remote machine and to script commands that include a login name, password, port number, or combination of those items.

Option Description
on host

Execute the command on a remote system (one other than the one where the current sp_ctrl session is running). You are prompted for login credentials for the remote system. If used, must be the last component of the command syntax.

Example: sp_ctrl(sysB)>status on SysA

on host:portnumber

Execute the command on a remote system when a remote login and port number must be provided. If used, must be the last component of the command syntax.

Example: sp_ctrl(sysB)>status on SysA:8304

on login/password@host

Execute the command on a remote system when a remote login, password, and host name must be provided. If used, must be the last component of the command syntax.

Example:sp_ctrl(sysB)>status on john/spot5489@SysA

on login/password@host:portnumber

Execute the command on a remote system when a remote login, password, host name, and port number must be provided. If used, must be the last component of the command syntax.

Example: sp_ctrl(sysB)>status on john/spot5489@SysA:8304

abort service

Use the abort service command to terminate a SharePlex replication process (service) immediately, whether or not that process has finished reading from, or writing to, its queues. This command is effective when you cannot wait for a process to stop gracefully, or in unusual circumstances when a process will not shut down when you issue the stop command.

This command does not affect replicated data. The data remains safely in the queues, and SharePlex resumes normal processing when the process is started again.

A process aborted with the abort service command remains stopped even if SharePlex is shut down and re-started. Only the start command can start it again.

The abort service command provides options with which you can abort a process for any (or all) systems, or for a named queue, without affecting replication for other routes.

Usage

Supported sources:

Oracle

Supported targets: All
Authorization level: Operator (2); Administrator (1) to abort Capture
Issues for:

abort service for Capture, Read and Export are issued for the source system.

abort service for Import and Post are issued for the target system.

Related commands: start, stop

Syntax

Basic command Command options Remote options
abort service service

[to host]

[from host]

[for datasource]

[for datasource-datadest]

[queue queuename]

[ on host |

on host:portnumber |

on login/password@host |

on login/password@host:portnumber ]

Syntax description
Component Description
service

Required. The SharePlex replication process you want to abort. Valid values are:

capture

read

export

import

post

to host

This option aborts Export to a designated system, while allowing Export to other systems to continue.

  • host is the name of the target system.

Example:

sp_ctrl(sysA)> abort service export to sysB

In this example, Export is aborted from sysA to sysB, but other Export processes from sysA to other target systems will continue.

from host

This option aborts Import from a designated system, while allowing Import from other systems to continue.

• host is the name of the source system.

Example:

sp_ctrl(sysD)> abort service import from sysC

In this example, Import from sys C is aborted on sysD, but other Import processes on sysD from other source systems will continue.

for datasource

This option aborts Capture or Read for a designated datasource, but other replicating datasources on the same system are unaffected.

  • datasource is expressed as o.SID, where SID is the ORACLE_SID of the source Oracle instance.

Example:

sp_ctrl(sysA)> abort service read for o.oraA

In this example, Read is aborted on sysA for instance oraA, but other Read processes for other instances on sysA will continue.

for datasource-datadest

This option aborts Post for a designated source SID-target SID data stream, while allowing other Post activities to continue.

  • datasource is expressed as o.SID, where SID is the ORACLE_SID of the source Oracle instance.
  • datadest is expressed as o.SID, where SID is the ORACLE_SID of the target Oracle instance.

Example:

sp_ctrl(sysC)> abort service post for o.oraA-o.oraC

In this example, Post is aborted on sysC for instance oraA replicating to oraC, but other Post processes on sysC will continue.

queue queuename

This option aborts the Export, Import or Post process associated with a named queue, while allowing replication through other named queues to continue.

  • queuename is the name of the queue.

Example:

sp_ctrl(sysA)> abort service export queue QA

In this example, Export of data through named export queue QA is aborted on sysA, but Export will continue for data assigned to all other named queues.

Remote options

These options enable you to issue the command on a remote machine and to script commands that include a login name, password, port number, or combination of those items.

Option Description
on host

Execute the command on a remote system (one other than the one where the current sp_ctrl session is running). You are prompted for login credentials for the remote system. If used, must be the last component of the command syntax.

Example: sp_ctrl(sysB)>status on SysA

on host:portnumber

Execute the command on a remote system when a remote login and port number must be provided. If used, must be the last component of the command syntax.

Example: sp_ctrl(sysB)>status on SysA:8304

on login/password@host

Execute the command on a remote system when a remote login, password, and host name must be provided. If used, must be the last component of the command syntax.

Example:sp_ctrl(sysB)>status on john/spot5489@SysA

on login/password@host:portnumber

Execute the command on a remote system when a remote login, password, host name, and port number must be provided. If used, must be the last component of the command syntax.

Example: sp_ctrl(sysB)>status on john/spot5489@SysA:8304
