SQL Server Setup (mss_setup)

Overview

Run the Database Setup utility for SQL Server (mss_setup) on a Microsoft SQL Server system to establish SharePlex as a SQL Server database user. This utility creates the following:

  • A SharePlex user account with the db_owner role
  • Tables and indexes for use by SharePlex and owned by the SharePlex user in a database of your choosing
  • A default database connection.

Supported databases

For supported SQL Server platforms and versions, see the SharePlex Release Notes.

Guidelines for use

  • A system DSN (data source name) must exist for the SQL Server database. SharePlex Post uses the DSN to connect to the database through ODBC.
  • Run the Database Setup utility on all SQL Server instances in the SharePlex replication configuration.
  • Within a cluster, run the Database Setup utility on the node to which the shared disk that contains the variable-data directory is mounted.
  • For consolidated replication, run the Database Setup utility for each variable-data directory.

Required privileges

Review the following requirements to ensure that the setup succeeds.

  • The Database Setup utility must be run as a SQL Server System Administrator in order to grant SharePlex the required privileges to operate on the database and to create the SharePlex database account and objects.

  • The sysadmin role is required to run mss_setup, but it is not required by the SharePlex database account used to run SharePlex replication (the SharePlex User). The db_owner role is required by the SharePlex User account and it is granted by mss_setup (for source and target).

  • (Cloud installations) Common restrictions on privileges in cloud-hosted database services make it difficult for the setup utility to succeed in every possible type of scenario. To ensure that the database setup succeeds, only use the setup utility for the following purposes: To do a first-time database setup with a new SharePlex user, or, to modify an existing SharePlex user that either owns the database or has access to it.

Run Database Setup for SQL Server

  1. Shut down any running SharePlex processes and sp_cop on the SQL Server system.

  2. Run the mss_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> mss_setup -p9400

Table 9: Setup prompts and responses

Prompt Response

Enter the Microsoft SQL Server DSN name [] :

Enter the data source name (DSN) that connects to SQL Server. Make certain the DSN is a system DSN, not a user DSN.

Enter the Microsoft SQL Server Administrator name :

Enter the name of the SQL Server Administrator. This user will perform the setup work on the SharePlex account and schema.

Enter the password for the Administrator account :

Enter the password of the Administrator.

Enter the database name:

Enter the name of the database where you want to install the SharePlex objects.

Database name database does not exist. Would you like to create it? [y] :

If this prompt is displayed, the specified database does not exist. Press Enter to have the setup utility create it for you.

Would you like to create a new SharePlex login [y]:

Press Enter to accept the default to create a new SharePlex database user account, or enter n to use an existing account as the SharePlex database user.

Enter the name of the existing SharePlex login:

Enter the name of the new SharePlex login:

One of these prompts is displayed depending on whether you elected to create a new user or use an existing user. Enter the name of the SharePlex user.

 

Enter the password for login:

Enter the password of the SharePlex user account.

Re-enter the password for login :

Enter the SharePlex password again.

Will this database be used as a source?

Accept the default of n if the database will only be a target. Enter y if this database will be a source database for SharePlex. A response of y prompts the setup to prepare the database for data capture and installs the SharePlex account and objects.

A successful setup terminates with a message similar to the following:

Completed SharePlex for Microsoft SQL Server database configuration

Database Setup for Oracle Cloud-ExaCS and DBCS

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:

  • A SharePlex account
  • Tables and other objects for use by SharePlex and owned by the SharePlex account
  • Default connection for the SharePlex user

It is recommended that you review all of the content in this topic before running the setup utility.

Supported Databases

Oracle source or target on supported platforms

When to Run Oracle Setup

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:

  • If you intend to use transportable tablespaces or a cold copy (such as export/import, store/restore from tape, FTP), run the Database Setup utility during SharePlex installation.

  • If you intend to use a hot backup to establish the target data, do not run the Database Setup utility. You will run it when you perform the initial synchronization procedure.

    Note: If you run the Database Setup utility before the backup and recovery, the setup gets overwritten, and you will need to re-run it again after the backup and recovery.

Supported Oracle Connections

The setup utility can configure any of the following connections for the SharePlex user to use when connecting to the database.

Database type Connection
PDB with ASM

TNS alias for the PDB and either TNS or bequeath for the ASM instance.

Required Run Privileges

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;

Privileges Granted to SharePlex

  • The Database Setup utility grants to the SharePlex database user the following privileges.

    Privilege granted

    Description

    DBA role

    The Database Setup utility grants DBA role and unlimited resource privileges, tablespace privileges, and read privileges to the redo logs.

    Default Oracle profile

    By default this profile has the unlimited resource privileges originally assigned by Oracle.

    Grants

    The following grants are issued to SharePlex:

    • To access the data dictionary (outside the DBA roles) if O7_DICTIONARY_ACCESSIBILITY is set to FALSE:

      grant select any dictionary toSharePlexUser;

    • To replicate DDL:

      grant select any table toSharePlexUserwith admin option;

      grant create any view toSharePlexUserwith admin option;

    Requirements

    • Install the database client on the system where you are running Oracle Setup. Consult the Oracle documentation for the appropriate client version to use with the database.
    • Run the Database Setup utility for all source and target Oracle instances in the SharePlex replication configuration.
    • Within a cluster, run the Database Setup utility on all nodes of the cluster. This ensures that the SharePlex settings in the Windows Registry include the correct ORACLE_SID.
    • For a consolidated replication topography, or other topology with multiple variable-data directories, run the Database Setup utility for each variable-data directory.

    • 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.

    • If the Oracle database is a multitenant container database, run the Database Setup utility for each pluggable database involved in a replication scenario. A SharePlex user and schema objects must exist in each PDB.
    • If you run the Database Setup utility when there is an active configuration, the DDL that the setup performs to install or update the SharePlex internal tables will be replicated to the target. To work around this issue, set the SP_OCT_REPLICATE_ALL_DDL parameter to 0 before running the utility, then return the parameter to its previous setting after the setup is complete. This parameter takes effect immediately.

    SharePlex Schema Storage Requirements

    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.

    Run Database Setup for Oracle Cloud-ExaCS and DBCS

    Important! The Oracle instance must be open before this procedure is performed.

    1. Shut down any SharePlex processes that are running, including sp_cop.

    2. 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

    3. 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.

    4. For connection type, select Oracle.
    5. Refer to the following table for the prompts and responses to configure SharePlex correctly for the desired connection type.

    Table 10: Setup prompts and response

    Prompt Response
    Will SharePlex install be using a BEQUEATH connection? (Entering 'n' implies a SQL*net connection):

    Press Y to use a local BEQUEATH connection, or press N to use a TNS alias connection.

    Note: Press N to use a TNS alias if:

    • the database is a multitenant database
    • SharePlex is capturing from, or posting to, a remote database, such as one on Amazon RDS.
    • the database is in a cluster (such as Oracle RAC)

    Are you configuring SharePlex for an AWS RDS database?

    Press N if you are not configuring SharePlex for an Oracle database on RDS.

    Press Y if you are configuring SharePlex for an Amazon AWS RDS database.

    One of the following prompts is shown:

    • If you selected BEQUEATH= Y:

      Enter the Oracle SID for which SharePlex should be installed:

    • If you selected BEQUEATH = N:

      Enter the TNS alias for which SharePlex should be installed:

    Non-multitenant database: Accept the default or type the correct SID or TNS alias.

    On RAC, the TNS alias must be a global alias.

    Multitenant database: Type the TNS alias of the PDB.

    Amazon RDS: Type the TNS alias of the RDS database.

    One of the following prompts is shown:

    • If the database is not on RDS:

      Enter a DBA user for SID:

    • If the database is on RDS:

      In order to create the SharePlex tables and user account, we must connect to the RDS database using the RDS primary user.

    Non-multitenant database: Type the name of a database user that has DBA privileges.

    Multitenant database: Type the name of a common user who has the required privileges to install the account and objects.

    Amazon RDS database: Type the name of the RDS primary user.

    One of the following prompts is shown:

    • If the database is not on RDS:

      Enter password for the DBA account, which will not echo:

    • If the database is on RDS:

      Enter the password for the RDS primary user, which will not echo.

    Non-multitenant database: Type the password of the DBA user.

    Multitenant database: Type the password of the common user. Omit the @ and the rest of the connect string. SharePlex constructs the connect string in the proper format.

    Amazon RDS database: Type the password of the RDS primary user.

     

    Current SharePlex user is user.

    Would you like to create a new SharePlex user?

    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:

    • The following prompts are only shown if the database is a source on ASM.
    • If this is an Oracle target, the setup is now complete.

     

    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 Cloud-ExaCS and DBCS.

    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.

     

    1. After completion of the Oracle setup, the ora_setup.config file will be generated inside <Installation_directory>/var/data.
    Note about the tnsnames file

    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.

    • SharePlex environment variables

    SharePlex uses the following environment variables, which you may need to set in certain situations. Usually you must perform additional steps before or after setting a variable, so refer to the recommended instructions before setting a SharePlex variable.

    Environment Variable Description
    EDITOR Sets the default ASCII text editor for sp_ctrl commands that use one, for example the create config command.
    HOST Sets a host name for all locally run sessions of sp_ctrl.
    SP_COP_TPORT

    Sets a non-default port number for an instance of SharePlex. The default port number is 2100. You may need to set a different port number if one of the following is true:

    • You are setting up additional instances of sp_cop.
    • A different port number than 2100 must be used.
    SP_SYS_HOST_NAME

    Sets the host name that SharePlex binds to during configuration activation. This variable is used for the following:

    • Sets the virtual IP address (also known as the global cluster package name) on a clustered system, such as Oracle RAC. This variable must be set on all cluster nodes.
    • In the case where there are multiple network cards on Windows, it must be set to the network card or IP address that you want SharePlex to use as the local host. Otherwise, if the server reboots after the SharePlex configuration is activated, the IP address may bind to a different network card from the one that is bound in the replication configuration.

    • If SP_SYS_HOST_NAME is set to an IPV6 address on the source system, SharePlex on the target system must be version 9.0 or later.

    SP_SYS_VARDIR Sets the full path to the SharePlex variable-data directory so that sp_cop can locate the configuration data, queues, logs and other information. If there is only one instance of sp_cop on the local system, this variable is set by default*. If there are multiple instances of sp_cop on the local system, always set this variable to point to the correct variable-data directory of an instance before setting any other SharePlex variables for that instance.
    SP_SYS_SECURE_MODE

    Suppresses the output of the compare and repair SQL log file for all compare and repair runs while the current instance of SharePlex is running. This variable must be set before starting SharePlex, so if the sp_cop process is running it must be restarted after setting this variable. When sp_cop is run with this environment variable, the compare and repair commands will not put data into SQL files and the Post process will not put data into the SharePlex error log.

    On Windows, it is set in the Windows Registry.

    To set an environment variable on Windows

    Set the environment variable by adding it to the SharePlex node of the Windows Registry.

    Important! Incorrect Registry settings can adversely affect the operation of SharePlex. Consult a System Administrator if you need help with this procedure.

    1. Shut down the SharePlex service.
    2. Open the Run dialog. The location varies with the Windows version.
    3. In the Run dialog, type regedit to run the Registry Editor.
    4. Expand the SharePlex node:

      \HKEY_LOCAL_MACHINE\Software\Wow6432node\Quest Software\SharePlex

    5. Right click the port number of the SharePlex instance to which you want to add a variable, then select New, then String Value.
    6. Under the Name column, right click the new variable, then select Rename.
    7. Type the correct name.
    8. Double click the new variable.
    9. Under Value Data, enter the string for the new variable and then click OK.
    10. Exit the Registry.
