SharePlex 10.2.1 - Upgrade Guide for Oracle Source

PostgreSQL Setup (pg_setup)

Overview

Run the Database Setup utility for Postgres (pg_setup) to establish a user account, schema, and tables for use by SharePlex.

Supported databases

All implementations of the Postgres open-source database on supported platforms

Fujitsu Enterprise Postgres Prerequisite

Fujitsu Postgres contains a customized ODBC driver designed to run with the shared libraries supplied by Fujitsu Postgres. In order to ensure the proper configuration, you must create a symbolic link to ensure that the correct libraries are found at runtime.

Issue Description

If you attempt to run the pg_setup program prior to creating the symbolic link, pg_setup will fail with the following error message:

Error: [unixODBC]invalid connection option "target_server"

To create a symbolic link

To ensure that the proper library gets loaded, first locate the path to the directory where the Fujitsu Postgres libraries are installed (for example /opt/fsepv95server64/lib). Then create a symbolic link in the SharePlex OPTDIR/lib/hooks directory pointing to the libpq.so.5 library in the Fujitsu Postgres library directory. For example:

cd /opt/splex/lib/hooks

ln –s /opt/fsepv95server64/lib/libpq.so.5

Guidelines for use

  • Run the Database Setup utility on all target Postgres instances in the SharePlex replication configuration.
  • Within a server cluster, run the Database Setup utility on the node to which the shared disk that contains the SharePlex variable-data directory is mounted.
  • For consolidated replication, run the Database Setup utility for each variable-data directory.
  • Supply a DSN (data source name) as the connection method.

Required privileges

Review the following requirements to ensure that the setup succeeds.

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

  • (Symfoware only) If the person who is running the setup utility is not a Fujitsu Enterprise Postgres owner, set the environment variable LD_LIBRARY_PATH to include the path to the lib subdirectory in the Fujitsu Enterprise Postgres installation directory. The LD_LIBRARY_PATH is set in the .bash_profile file of the Fujitsu Enterprise Postgres owner.

    Example:

    export LD_LIBRARY_PATH= /opt/symfoserver64/lib:$LD_LIBRARY_PATH

    If you do not set this path, the following error occurs:

    symbol lookup error: /opt/fsepv95client64/odbc/lib/psqlodbca.so: undefined symbol: PQconnectdbParams

  • 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.

    • On Amazon RDS, you might need to grant usage/privileges on the target schema and tables to the SharePlex user, as shown in the following example:

      Log in as the schema owner, then issue the following commands:

      grant usage on schema schema_name to user_name;

      grant all privileges on all tables in schema schema_name to user_name;

Run Database Setup for PostgreSQL

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

  2. Run the pg_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.

    $ /users/splex/bin> pg_setup -p9400

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

Press Enter to accept the default to create a new SharePlex database user account and schema of the same name in the specified database, or enter n to use an existing SharePlex account.

Enter the name of the new SharePlex user:

Enter the name of the existing SharePlex user:

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.

Configure SharePlex to support PostgreSQL database on Azure platform

You can configure SharePlex to support the PostgreSQL database on the Azure platform using the below steps:

  1. Add the DSN entry in the Odbc.ini file at /etc/odbc.ini and the …/var/odbc directory.
  2. Copy the /etc/odbcinst.ini file to the …/var/odbc directory.
  3. Run the PostgreSQL setup utility.
This process creates the SharePlex tables, login and user accounts needed to run SharePlex replication.

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 7: Setup prompts and responses

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] :
