SharePlex 9.0.1 - Upgrade Guide

Verify_Partitions



The method of creating and storing partition schemes and row partitions for horizontal partitioning has changed in this release. This information no longer is stored in the database.

When you run database setup during an upgrade, it converts the data from the SHAREPLEX_PARTITION table to the new internal storage format. After the conversion, you can view the partitions with the view partitions command in sp_ctrl to ensure that the partitions converted properly.

Note: For more information about the view partitions command, see the.

To view row partitions

  1. Run sp_ctrl on the source system.
  2. Issue the following command with either option, depending on whether you want to view all partitions or just those for a particular partition scheme.

    sp_ctrl> view partitions for {scheme_name | all}

The following is an example of converted partition schemes. Note that the conversion program populates the Name field with the name of the queue from the Route column.

Scheme        Name           Route                            Hash     Condition
-----------   -------------  ------------------------------   ------   ---------------
HASH4         hash           sys02:hash|#@o.ora112            4        ROWID
TEST_CT       highvalues     sys02:highvalues@o.ora112                 sales>=10000
TEST_CT       lowvalues      sys02:lowvalues@o.ora112                  sales<10000

Target upgrade for SAP ASE

This section applies to upgrades from SharePlex version 8.5 to the current release.

Version 8.6 changed the way that SAP ASE is defined in the routing map in the configuration file and the way that connection settings are defined for Post.

  • In the configuration file, the routing map now requires r.database_name, where database_name is the actual name of the target database, not a DSN.
  • The connection information for Post to connect to SAP ASE is now configured through the connection command, rather than in the target configuration created by the target command.

To complete the upgrade from version 8.5 to the current version of SharePlex for an SAP ASE target, while keeping the current configuration active so that replication can continue, use the following procedure.

Note: This upgrade keeps the routing map as configured in version 8.5 and only changes the Post connection settings.

  1. From the Unix command line of the operating system, run the following command, where database_name is the actual name of the target database (not a DSN).

    export SP_TARGET_DATABASE=database_name

  2. Start sp_cop.

    /product_dir/bin/sp_cop

  3. In sp_ctrl, issue the show post command. The state should be "stopped-due to error." If Post did not stop, stop it with the stop post command.

    stop post [for datasource-datadest]

  4. Issue the following commands, using the new connection command, but this time substitute the DSN of the database for DSN. Do not specify the actual database name in this case.

    connection r.DSNset user=name_of_Post_database_user

    connection r.DSNset password=password

  5. Start Post.

    start post [for datasource-datadest]

 

SharePlex utilities

Contents

HANA Setup (hana_setup)

Overview

Run the Database Setup utility for HANA (hana_setup) on a target HANA system to establish a user account, schema, and tables for use by SharePlex.

Supported databases

HANA on supported platforms

Guidelines for use

  • Run the setup utility on all target HANA instances in the SharePlex replication configuration.
  • Within a server cluster, run the setup utility on the node that has the mount point to the shared disk that contains the SharePlex variable-data directory.
  • For consolidated replication, run the setup utility for each variable-data directory.
  • The only supported connection method to HANA is by connect string. Connection through a DSN is not yet supported.

  • Make certain that you assign the required permissions that are shown in this setup process.

Required privileges

The setup utility must be run as a HANA Administrator in order to grant SharePlex the required privileges to operate on the database and to create the SharePlex database account.

Run Database Setup for HANA

  1. Shut down any running SharePlex processes and sp_cop on the target system.
  2. Run the hana_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> hana_setup -p9400

Table 1: Setup Prompts and Responses

Prompt Response

Enter the connection string [] :

Enter a connection string that connects to the HANA database system. The required components of a connection string for SharePlex to connect to HANA are:

  • SERVERNODE: The name of the target HANA server, then a colon, then the HANA port number.
  • DRIVER: The path to the HANA ODBC driver.
  • CHAR_AS_UTF8: This must be passed as CHAR_AS_UTF8=1.

Example:

SERVERNODE=server1.dept.abc.corp:30015;DRIVER=/usr/sap/hdbclient/libodbcHDB.so;CHAR_AS_UTF8=1

You do not have to supply a user, password, and default database, because the setup utility prompts for those.

Enter the HANA Administrator name :

Enter the name of the HANA Administrator. This user will perform the work on the SharePlex account.

Enter the password for the Administrator account :

Enter the password of the Administrator.

Enter the name of the database :

Enter the name of the database that you want to contain the tables and other objects for use by SharePlex. You can enter the name of a new or existing database.

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 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.

 

Enter the password of the SharePlex user :

Enter the password of the SharePlex user account.

Re-enter the password for the SharePlex user :

This prompt is only shown if you created a new user. Enter the SharePlex password again.

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

Completed SharePlex for HANA database configuration

SharePlex User name: splex

Database name: ndb5

Target specification in SharePlex configuration: r.ndb5

Grant privileges to SharePlex

Before you start SharePlex replication to a HANA target, grant the following privileges to the SharePlex database user in that target (where SP_USER is the name of the SharePlex database user):

  • GRANT USER ADMIN TO sp_user;
  • GRANT TABLE ADMIN TO sp_user;
  • GRANT CATALOG READ TO sp_user;
  • GRANT DATA ADMIN TO sp_user WITH ADMIN OPTION;
  • GRANT ROLE ADMIN TO sp_user WITH ADMIN OPTION;

Additionally, log in as the owner of each schema that contains objects that you want to replicate, then make the following grants on the schema:

  • GRANT CREATE ANY ON SCHEMA schema_name TO sp_user;
  • GRANT DEBUG ON SCHEMA schema_name TO sp_user;
  • GRANT DELETE, DROP, EXECUTE, INDEX, INSERT, SELECT, UPDATE ON SCHEMA schema_name TO sp_user;
