When setting up SharePlex to work with an Oracle database, you provide the ORACLE_SID and then SharePlex gets the ORACLE_HOME from the Windows Registry. The values are stored in the SharePlex environment. SharePlex uses the Oracle libraries that are in the location specified with ORACLE_HOME.
To determine the ORACLE_SID and ORACLE_HOME being used by SharePlex
Issue the orainfo command in sp_ctrl.
sp_ctrl (mysysl11:2101)> orainfo
Oracle instance #1:
Oracle SID ora12
Oracle HOME /oracle/products/12
Oracle Version 12
Oracle instance #2:
Oracle SID ora12
Oracle HOME /oracle/products/12
Oracle Version 12
To determine the default ORACLE_SID and ORACLE_HOME on Windows
View the Oracle entry in the Registry at \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE.
The Database Setup utilities automatically configure a source or target database to allow SharePlex connections and to establish required database components that support replication.
Run the Database Setup utility for MySQL (mysql_setup) on a MySQL system to establish SharePlex as a MySQL database user. This utility creates the following:
Review the following requirements to ensure that the setup succeeds.
Run the mysql_setup program from the bin subdirectory of the SharePlex product directory.
Important! If you installed the SharePlex instance on any port other than the default of 2100, use the -p option to specify the port number. For example, in the following command the port number is 9400.
C:\users\splex\bin> mysql_setup -p9400

Use the Database Setup utility for Oracle (ora_setup) to establish SharePlex as an Oracle user and create the required SharePlex database objects. This setup utility creates the following:
It is recommended that you review all of the content in this topic before running the setup utility.
Oracle source or target on supported platforms
Whether or not to run this utility at the time of SharePlex installation depends on whether the database is a source, intermediary, or target database, and on how you intend to synchronize the data. To view the initial synchronization procedures, see the SharePlex Administration Guide.
| System Type | When to run Oracle Setup |
|---|---|
|
Source system |
During installation of SharePlex |
| Intermediary system | An intermediary system is used in a cascading configuration, where SharePlex replicates data to a remote system (or systems) and then sends that data from the intermediary system to the final target. If you intend to configure SharePlex to post data to a database on an intermediary system, and you intend to use a hot backup to establish the data on that system and the target, do not run the Database Setup utility on the intermediary or target systems. You will run it when you perform the initial synchronization procedure. |
|
Target system |
Depends on the method that you will use to synchronize the source and target data when you are ready to activate replication:
|
The setup utility can configure any of the following connections for the SharePlex user to use when connecting to the database.
| Database type | Connection |
|---|---|
| Database with or without ASM | Bequeath |
|
Database with or without ASM |
TNS alias |
| PDB with ASM |
TNS alias for the PDB and either TNS or bequeath for the ASM instance. |
|
Amazon RDS |
TNS alias |
The user who runs the Database Setup utility must have the following privileges:
Amazon RDS source or target
The user who runs the setup utility must be the primary user that was created when the Oracle RDS instance was created. You are prompted for this user during the setup.
Non-multitenant (standard) database
The user who runs the setup utility must have DBA privileges.
Multitenant database
The user who runs the setup utility should have SYSDBA privileges (recommended), but at minimum the user should be a DBA user with privileges for sys.users$ and sys.enc$. The minimum following grants are required for the SharePlex user:
create user c##sp_admin identified by sp_admin;
grant dba to c##sp_admin container=ALL;
grant select on sys.user$ to c##sp_admin with grant option container=ALL;
|

SharePlex supports local BEQUEATH connections or remote connections using a TNS alias. Be prepared to supply Oracle Setup the needed connection values for whichever connection you want to use. If using TNS, the tnsnames.ora file must be configured prior to running setup.
The Database Setup utility for Oracle installs some database objects for use by SharePlex. The storage requirements for these objects should be satisfied before running Oracle Setup. See the following table.
| Storage | Description |
|---|---|
| SharePlex objects tablespace |
The Database Setup utility installs some tables into a tablespace of your choosing. All but the SHAREPLEX_LOBMAP table use the default storage settings of the tablespace. The SHAREPLEX_LOBMAP table contains entries for LOBs stored out-of-row. It is created with a 1 MB INITIAL extent, 1 MB NEXT extent, and PCTINCREASE of 10. The MAXEXTENTS is 120, allowing the table to grow to 120 MB. Preferred action: If you enable supplemental logging for primary and unique keys, you can set the SP_OCT_ENABLE_LOBMAP parameter to 0, and nothing will be stored in the SHAREPLEX_LOBMAP table. In this case, you do not have to consider its size growth. It is recommended that you enable supplemental logging for primary and unique keys to maximize the performance of the Read process. Alternate action: The default storage usually is sufficient for SHAREPLEX_LOBMAP, permitting more than 4 million LOB entries. If the Oracle tables to be replicated have numerous LOB columns that are inserted or updated frequently, consider increasing the size the SharePlex tablespace accordingly. Take into account that this table shares the tablespace with other SharePlex tables. If the database uses the cost-based optimizer (CBO) and the tables that SharePlex processes include numerous LOBs, incorporate the SHAREPLEX_LOBMAP table into the analysis schedule. Note: A new installation of SharePlex does not change storage parameters from a previous installation. |
| SharePlex temporary tablespace |
The Database Setup utility prompts for a temporary tablespace for SharePlex to use for sorts and other operations, including sorts performed by the compare commands. The default temporary tablespace is the one where the SharePlex objects are installed. If you plan to use the compare commands to compare large tables, especially those without a primary or unique key, specify a dedicated temporary tablespace for SharePlex. |
| SharePlex index tablespace |
The Database Setup utility prompts for a tablespace to store the indexes for the SharePlex tables. The default index tablespace is the one where the SharePlex objects are installed. To minimize I/O contention, specify a different index tablespace from the one where the tables are installed. Note: If indexes from a previous version of SharePlex are installed in the SharePlex objects tablespace, you can move them to a different tablespace and then specify that tablespace when you run the setup utility. |
Important! The Oracle instance must be open before this procedure is performed.
Run the Database Setup program from the command prompt of the operating system, using the full path from the SharePlex bin subdirectory.
Important! On Windows, if you installed SharePlex on any port other than the default of 2100, use the -p option to specify the port number. For example, in the following command the port number is 9400:
C:\users\splex\bin>ora_setup -p9400
Specify whether the system is a source system, a target system, or both a source and target system in the SharePlex configuration.
Note: This prompt only appears the first time that you run setup for this database.

Press N to update an existing SharePlex account or Y to create a new SharePlex account. Type the credentials when prompted. You are allowed five attempts to type a valid password for an existing SharePlex user. Passwords are obfuscated. Important!If there is an active configuration and you changed the SharePlex schema, copy the SharePlex objects from the old schema to the new one to preserve the replication environment.
|
|
Do you want to enable replication of tables with TDE?
|
Press N since TDE is not supported for RDS.
|
| Enter the default tablespace for use by SharePlex:
|
Press Enter to accept the default or type the name of a different tablespace.
|
| Enter the temporary tablespace for use by SharePlex:
|
Press Enter to accept the default or type the name of a different tablespace.
|
| Enter the index tablespace for use by SharePlex:
|
Press Enter to accept the default or type the name of a different tablespace.
|
| Will the current setup for sid: SID be used as a source (including cases as source for failover or primary-primary setups)?
|
Press Y if this is a source system or press N if this is a target system. Important: All systems in a primary-primary configuration (peer-to-peer) and in a high-availability configuration are considered to be source systems due to the bidirectional nature of the replication.
|
|
Note:
| |
|
ASM detected. Do you wish to connect to ASM using BEQUEATH connection?
|
Press Y for SharePlex to use a BEQUEATH connection to connect to the ASM instance, or press N to use a TNS alias. Important! If the database uses ASM and the database TNS alias is configured with a SCAN IP, then you must specify connection through an ASM TNS alias in order for SharePlex to connect to the ASM instance.
|
|
The following prompt is displayed if you did not select a BEQUEATH connection: Do you wish to keep connecting using the same user/password?
|
Press Y to use the same user and password as the login user, or press N to be prompted for a different user and password. Normally the user running SharePlex must be a member of the OSASM group. This does not apply if SP_OCT_OLOG_USE_OCI is set to the non-default value of 1. Also if you are using a BEQUEATH connection, the user running SharePlex must be a member of the OSDBA group. |
|
Note: If you selected to use a BEQUEATH connection to connect to ASM, the database setup is complete. Continue to Database Setup for Oracle. If you selected N, you need to supply a TNS alias, and the prompts continue.
| |
|
Enter the ASM tns alias to be used by SharePlex:
|
Type the name of the TNS alias.
|
|
Enter an ASM admin (has both sysdba and sysasm privilege) username for alias:
|
Type the name of a user with sysasm and sysdba privileges to the ASM instance.
|
|
Enter user password for user:
|
Type the password of the user.
|

SharePlex installs internal objects that include a package to support the SDO_GEOMETRY data type of the Oracle Spatial and Graph option. If this option is not installed in the database, the following prompt is shown: The SharePlex object that supports replication of SDO_GEOMETRY cannot be installed because the Oracle Spatial and Graph feature is not installed. Do you want to continue with the setup without support for SDO_GEOMETRY? [n]:
|
Press Y to continue the database setup without support for SDO_GEOMETRY, or press N to terminate ora_setup.
|
When you set up SharePlex for database connection through a TNS alias and ASM connection locally through a BEQUEATH connection (through OS authentication), it is important to set up the tnsnames.ora file correctly on each node. Assuming a SharePlex database account exists on the primary node, SharePlex will always connect to the primary ASM_SID automatically because it was provided when SharePlex was installed. However, upon failover, SharePlex must query the local v$asm_client view to get the correct ASM_SID of the failover instance. Therefore, ensure that the IP address of a given node is always listed first in the local tnsnames.ora file on that node.
Important! The Oracle instance must be open before this procedure is performed.
Run the Database Setup program from the command prompt of the operating system, using the full path from the SharePlex bin subdirectory.
Important!If you installed SharePlex on any port other than the default of 2100, use the -p option to specify the port number. For example, in the following command the port number is 9400:
C:\users\splex\bin>ora_setup -p9400
Specify whether the system is a source system, a target system, or both a source and target system in the SharePlex configuration.
Note: This prompt only appears the first time that you run setup for this database.
