Use the reset param command to restore a parameter to its default value. The change takes effect based on the parameter’s set-at point:
- For a set-at point of Live, the change takes effect immediately.
- For a set-at point of Restart Process, the change takes effect the next time the affected SharePlex process is started.
- For a set-at point of Restart Cop, the change takes effect the next time sp_cop is started (do not reboot the system).
Using command options
The following are guidelines for resetting SharePlex parameters.
- To reset a parameter that was set with the set param command on a global basis (without process-specific options), use the reset param command without options.
- To reset a parameter that has a process-specific value (set with one of the set param process-specific options), use one of the reset param process-specific options. Process- specific options can be used for parameters in the following modules:
| export |
SP_XPT |
Export process |
| import |
SP_IMP |
Import process |
| capture |
SP_OCT |
Capture process |
| post |
SP_OPO |
Post process |
| read |
SP_ORD |
Read process |
| |
|
|
Viewing current parameter settings
To view the names of SharePlex parameters, their values and set-at points, and whether or not process-specific values are in effect, use the list param command, as shown in the following example which shows both a global value for the Export process and a process-specific value for Export to sysB.

Syntax description
| paramname |
The name of the parameter that you want to restore to its default value. This argument is not case-sensitive.
Example:
sp_ctrl(sysA)> reset param SP_XPT_SO_SNDBUF
This resets the parameter for all Export processes on the system. |
Process-specific command options
| to host |
This option resets an Export parameter (SP_XPT_) for the Export processes to a designated target system. To restrict the command’s effect to the Export process associated with a named export queue, follow this option with the [queue queuename] option.
Example:
sp_ctrl(sysA)> reset param sp_xpt_so_sndbuf to sysB
In this example, the parameter is reset for Export to sysB, but other Export processes are not affected. |
| from host |
This option resets an Import parameter (SP_IMP_) for the Import processes from a designated source system. To restrict the command’s effect to the Import process associated with a named export queue, follow this option with the [queue queuename] option.
Example:
sp_ctrl(sysD)> reset param sp_imp_wcmt_msgcnt from sysC
In this example, the parameter is reset for Import from sys C, but other Import processes are not affected. |
| fordatasource |
This option resets a Capture or Read parameter (SP_OCT_ or SP_ORD_) for a designated source Oracle instance.
- datasource is expressed as o.SID, where SID is the ORACLE_SID of the source instance.
Example:
sp_ctrl(sysA)> reset param sp_oct_replicate_dload for o.oraA
In this example, the parameter is reset for the Capture process for instance oraA, but other Capture processes are not affected. |
| for datasource-datadest |
This option resets a Post parameter (SP_OPO_) for all Post processes posting data from one database to another. To restrict the command’s effect to the Post process associated with a named post queue, follow this option with the [queue queuename] option.
- datasource is expressed as o.SID, where SID is the ORACLE_SID of the source instance.
- datadest is expressed as o.SID, where SID is the ORACLE_SID of the target instance.
Example:
sp_ctrl(sysC)> reset param sp_opo_cont_on_err for o.oraA-o.oraC
In this example, the parameter is reset for the Post process for instance oraA replicating to oraC, but other Post processes are not affected. |
| queue queuename |
This option resets a parameter for an Export, Import or Post process associated with a designated named queue.
Example:
sp_ctrl(sysA)> reset param sp_opo_poster_delay queue QA
In this example, the parameter is reset for the Post process associated with named post queue QA, but other Post processes are not affected. |
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.
| 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 |
Use the set encryption key command to configure the Export and Import processes to use the AES encryption key that is generated with the create encryption key command.
The encryption key must be set with this command on the source and target systems.
For more information about configuring AES encryption, see the SharePlex Administration Guide.

Use the set log command to set the default parameters for the show log command. This command sets defaults for:
- The maximum number of lines to extract from the log.
- The maximum number of lines to display at once on the screen.
- The direction in which you want to view the entries (newest to oldest, or oldest to newest).
You can set any, or all, of those parameters at once with this command. There are no [on host] options for this command.

Syntax description
| filespec |
This argument specifies the wildcarded Oracle object (including schema owner) that the command will execute against. Without the for datasource option it assumes that the schema and objects are in replication and are contained within the active configuration.
Example:
sp_ctrl(sysA)> expand scott.%
In this example, the result will display all objects in the scott schema. |
| maxlines=number |
Use this option to set the default for the maximum number of lines of a log that the show log command displays. This option can be used alone or in combination with any other set log command options.
Examples:
sp_ctrl(sysA)> set log maxlines=50
sp_ctrl(sysA)> set log maxlines=50 lpp=34 reverse |
| lpp=number |
Use this option to set the default for the number of lines per screen for the show log command. This option can be used alone or in combination with any other set log command options.
Examples:
sp_ctrl(sysA)> set log lpp=34
sp_ctrl(sysA)> set log maxlines=50 lpp=34 reverse |
| reverse |
Use this option to start the show log output with the most recent entries. This option can be used alone or in combination with any other set log command options.
Examples:
sp_ctrl(sysA)> set log reverse
sp_ctrl(sysA)> set log maxlines=50 lpp=34 reverse |
| forward |
Use this option to start the show log output with the oldest entries. This option can be used alone or in combination with any other set log command options.
Examples:
sp_ctrl(sysA)> set log forward
sp_ctrl(sysA)> set log maxlines=50 lpp=34 forward |

Use the set param command to change the value of a SharePlex parameter. The new setting takes effect based on the parameter’s set-at point:
- For a set-at point of Live, the change takes effect immediately.
- For a set-at point of Restart Process, the change takes effect the next time the affected SharePlex process is started.
- For a set-at point of Restart Cop, the change takes effect the next time that sp_cop is started. Do not reboot the system.
Changing a parameter from its default value
When you change a parameter from its default value, SharePlex records the change in the variable-data directory, where all user-defined parameter values are stored. Default values are stored in the param-defaults file in the product directory.
The default settings of most SharePlex parameters are adequate for most replication operations, but some can be changed by an authorized SharePlex user when necessary. Those parameters are viewed with the list param basic command.
The rest of the parameters are considered non-user-changeable. They are viewed with the list param all command. Do not change those parameters without the supervision of Quest Development or Technical Support team, or unless you are following a documented procedure in a SharePlex guide. Unless you are familiar with those parameters, changing them could adversely affect replication.
Using command options
The following explains how to use the set param command options.
| export |
SP_XPT |
Export process |
| import |
SP_IMP |
Import process |
| capture |
SP_OCT |
Capture process |
| post |
SP_OPO |
Post process |
| read |
SP_ORD |
Read process |
| |
|
|
You can use a process-specific value in conjunction with a global value for the same parameter. For example, you could set SP_XPT_SO_SNDBUF globally for all Export processes except the one transmitting to SysC; for that one you could set a different value by using the [to host value] process-specific option.
Viewing current parameter settings
To view the names of SharePlex parameters, their values and set-at points, and whether or not process-specific values are in effect, use the list param command, as shown in the following example which shows both a global value for the Export process and a process-specific value for Export to sysB.

Syntax description for global settings
| paramname value |
- paramname is the name of the parameter that you want to set. This argument is not case-sensitive.
- value is the new value for the parameter.
Example:
sp_ctrl(sysA)> set param SP_XPT_SO_SNDBUF 1024
In this example, the parameter is set globally for all Export processes
on the system. |
Syntax description for process-specific settings
| to host value |
This option sets an Export parameter (SP_XPT_) for all Export processes to a designated target system. To constrain the change to an Export process associated with a named export queue, use this option with the [queue queuename] option.
- host is the target system’s name.
- value is the new value for the parameter.
Example:
sp_ctrl(sysA)> set param sp_xpt_so_sndbuf to sysB 1024
In this example, the parameter is set for Export to sysB, but Export processes to other target systems are not affected. |
| from host value |
This option sets an Import parameter (SP_IMP_) for all Import processes from a designated source system. To constrain the change to an Import process associated with a named export queue, use this option with the [queue queuename] option.
- host is the source system’s name.
- value is the new value for the parameter.
Example:
sp_ctrl(sysD)> set param sp_imp_wcmt_msgcnt from sysC 10000
In this example, the parameter is set for Import from sys C, but Import processes from other source systems are not affected. |
| for datasource value |
This option sets a Capture or Read parameter (SP_OCT_ or SP_ORD_) for a designated datasource.
- datasource is expressed as o.SID, where SID is the ORACLE_SID of the source Oracle instance.
- value is the new parameter value.
Example:
sp_ctrl(sysA)> set param sp_oct_replicate_dload for o.oraA 1
In this example, the parameter is set for Capture for instance oraA, but other Capture processes for the same instance of sp_cop are not affected. |
| for datasource-datadest value |
This option sets a Post parameter (SP_OPO_) for all Post processes posting data from one database to another. To constrain the change to a Post process associated with a named post queue, use this option with the [queue queuename] option.
- 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.
- value is the new parameter value.
Example:
sp_ctrl(sysC)> set param sp_opo_cont_on_err for o.oraA-o.oraC 1
In this example, the parameter is set for the Post process for instance oraA replicating to oraC, but other Post processes are not affected. |
| queue queuename |
This option restricts the command’s effect to an Export, Import or Post process associated with a named queue.
- queuename is the named queue’s name.
When used, the queue queuename option must appear after the required and optional syntax, but before the new value, as shown below:
Example 1: Export process
sp_ctrl(sysA)> set param sp_xpt_so_sndbuf queue QA to sysB 1024
In this example, the parameter is set for the Export process associated with named export queue QA, but other Export processes are not affected.
Example 2: Import process
sp_ctrl(sysD)> set param sp_imp_wcmt_msgcnt from sysC queue QA 10000
In this example, the parameter is set for the Import process associated with named export queue QA, but other Import processes are not affected.
Example 3: Post process
sp_ctrl(sysC)> set param sp_opo_cont_on_err queue QA for o.oraA-o.oraC 1
In this example, the parameter is set for the Post process associated with named post queue QA for replication between oraA and oraC, but other Post processes are not affected.
Example 4: Post process
sp_ctrl(sysC)> set param sp_opo_cont_on_err queue QA 1
In this example, the parameter is set for the Post process associated with named post queue QA, but other Post processes are not affected. |
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.
| 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.
