SharePlex 11.4 - Installation and Setup guide

This section contains instructions for using the SharePlex uninstallation program to remove SharePlex from a system. The uninstaller permanently removes the replication environment from the system.

To preserve the replication environment, including the queues that store the data, you can install a SharePlex upgrade or reinstall the current version, rather than uninstall SharePlex. Before you upgrade or reinstall SharePlex, see the Release Notes for the version you are installing to determine if there are any special upgrade or installation requirements.

Uninstall SharePlex from UNIX/Linux

Remove SharePlex from Unix/Linux

Perform the following steps to remove SharePlex from Unix or Linux platforms:

Log on as a user who has privileges to remove the SharePlex directories.
Run sp_ctrl.
Issue the shutdown command to shut down SharePlex.

sp_ctrl> shutdown
Exit sp_ctrl.
Use the following command to make certain that no SharePlex processes are running.

# ps -ef | grep sp_
Kill any processes that are still running.
Remove the SharePlex product directory, variable-data directory, and the hidden .shareplex directory from the system.

Note: If there are multiple installations, do not remove the hidden directory.

Drop the SharePlex database user from the database.

Note: If desired, remove any objects that SharePlex installs in the database. These objects begin with SHAREPLEX_ or shareplex_. You can remove any such objects using standard SQL commands.

Important!

Points to remember when removing the SharePlex objects from the PostgreSQL database:

Remove the replication slot that was created during pg_setup using the following query:

select pg_drop_replication_slot(<slot_name>);

Remove replication origins created by the Post-process:
- Get replication origin names using the following query:
  
  Select a roname from pg_replication_origin that is similar to "sp_post_%";
- Remove these origins with the following query:
  
  select pg_replication_origin_drop(<origin_name>);

If the SP_CAP_DENIED_SESSION_PG parameter was used, remove the replication origin created:
- Get replication origin names using the following query:
  
  Select a roname from pg_replication_origin that is similar to "sp_deny_%";
- Remove these origins with the following query:
  select pg_replication_origin_drop(<origin_name>);

Advanced installer options

The use of additional command line options when installing SharePlex is usually not necessary. These options are typically employed when working with Support to resolve specific issues.

The installer command line options and their descriptions follow:

USAGE

tpm [<options>] [ [<package> | <location>] ... ]

OPTIONS

-v, --verbose Turns verbose mode on

-h, -?, --help Prints out this message

--debug Starts the interactive debugger

--info Print information about installed

packages

--install Perform product installation

--remove Perform product deinstallation

--commit Commit last installation

--revert Revert last installation

-t, --tmp <directory> Temporary directory location

-d, --directory <directory> Working directory

-f, --force Unconditionally update existing files

--no-cleanup Do not perform cleanup on failure

--nocleanup Same as --no-cleanup, for compatibility

--list List the content of the archive

--extract Extract the archive into the current directory

-r, --responses <yaml file> Use the responses from a specified file

-D, --defaults Accept default answers

-l, --log Leave the installation log file

DESCRIPTION

Provides package management facilities. Packages can be installed, removed, reverted or committed. The utility also figures out its role based on the command name of its invocation path. For example, "tpm-install" is treated as "tpm --install", "tpm-remove" as "tpm --remove", etc.

It can also be invoked as part of a self extracting package invocation, in which case it is treated as "tpm --install".

Note: All command line options for the .tpm file are preceded by two dashes.

Install SharePlex as root

You can install SharePlex as a root user. When you install as a root user, the installer prompts you to select whether or not to create the SharePlex user groups. When the installer creates the groups, it adds the SharePlex Administrator user to the spadmin group. For more information about these groups, see Assign SharePlex Users to Security Groups.

In a cluster, the installer adds the SharePlex groups to the primary node, but you must add them to the other nodes yourself.

Additionally, see Network checklist for instructions on adding the groups to a nameserver.

To install as root:

Log in to the system as a root user.
Copy the SharePlex installer file to a temporary directory where you have write permissions. The installer file has a naming format of:

SharePlex-release#-platform.tpm
Change the permissions of the file as follows:

# chmod 555 SharePlex-release#-platform.tpm
Run the installer as directed in Install SharePlex .
