SharePlex 9.2.8 - Installation and Setup for Oracle Source

The variable-data directory: This is the SharePlex working directory, where the queue files, log files and other components that comprise the current replication environment are stored.

Note: These directories are often referred to as productdir and vardir, respectively.

Do not remove, rename or edit any files or directories installed by SharePlex. Some directories contain hidden files that are essential for replication. Some files appear empty but must exist under their original names because they are referenced by one or more SharePlex processes. Some items in the directories are for use only under the supervision of Quest Technical Support.

Programs meant for general use in a production environment are documented in the published SharePlex documentation. If you do not find documentation for a program in a SharePlex directory, do not attempt to run it. Contact Quest Technical Support first.

The directory structure and files within the two main SharePlex directories differs slightly between the UNIX and Windows platforms. Files and directories can vary from version to version of SharePlex, but the basic structure appears as follows.

SharePlex product directory

Sub-directory	Contents
BACKUP	Uninstall information
bin	SharePlex executable files
config	Internally used content.
data	Default parameter settings
doc	Catalog of exception messages
install	(Unix and Linux only) Scripts related to installation, licensing and upgrades
lib	SharePlex shared libraries
log	SharePlex log files
mks_oe	Runtime installation files for third-party software used by SharePlex.
util	SharePlex utilities
.app-modules	(Unix and Linux only) Hidden internal directory that contains raw executables. Do not use the contents of this directory to launch processes.
.meta-inf	(Unix and Linux only) Hidden internal directory that contains meta information used during the installation process.

SharePlex variable-data directory

Sub-directory	Contents
config	Configuration files for this installation of SharePlex.
data	Status Database, configuration activation information, user-defined parameter settings, and other user-defined files that direct replication activities.
db	Configuration internal database for each activation of a configuration file.
downgrd	Information about SharePlex targets that are a lower version than the source.
dump	Core files (if a process fails)
log	SharePlex log files
rim	Queue files (working data files)
save	Information about active and inactive configurations.
state	Information about the current state of SharePlex when a configuration is active, such as the object and sequence caches.
temp	Used by the copy and append features and other SharePlex sync-related processes.
oos	Stores the transactions that contain out-of-sync operations when the SP_OPO_SAVE_OOS_TRANSACTION parameter is enabled.

SharePlex Installed Objects

Much of the replication process is controlled and tracked through a series of internal objects that are installed into the source or target database during the installation of SharePlex. They are essential for SharePlex to operate, so do not alter them in any way.

NOTE: Not all objects are used for all databases. Most are used for Oracle databases. If you do not see an object in your database, it is not relevant to the database, or the information is stored internally within the SharePlex configuration. If you see an object that is in your database but not in this list, it is not being used in the current release.

Table	Object type	Description
DEMO_SRC	Table	Used as the source table for the SharePlex demonstrations.
DEMO_DEST	Table	Used as the target table for the SharePlex demonstrations.
SHAREPLEX_ACTID	Table	Used by Capture to checkpoint its state.
SHAREPLEX_ANALYZE	Table	Used by the analyze command.
SHAREPLEX_CHANGE_OBJECT	Table	Used by users to stop and resume replication for an object.
SHAREPLEX_COMMAND	Table	Used for the flush, abort and purge commands.
SHAREPLEX_CONFIG	Table	Used by the activation and Capture processes to mark the start of a new activation.
SHAREPLEX_DATA	Table	Used by the SharePlex wallet for Oracle TDE replication.
SHAREPLEX_DATAEQUATOR	Table	Used by the compare and repair commands and the Post process to synchronize their operations.
SHAREPLEX_DATAEQUATOR_INSERT_TEMP	Table	Used as a temporary table by the compare and repair commands.
SHAREPLEX_DATAEQUATOR_UPDATE_TEMP	Table	Used as a temporary table by the compare and repair commands.
SHAREPLEX_DATAEQUATOR_DELETE_TEMP	Table	Used as a temporary table by the compare and repair commands.
SHAREPLEX_DDL_CONTROL	Table	Used to refine control of DDL that is enabled for replication by the SP_OCT_REPLICATE_ALL_DDL parameter.
SHAREPLEX_JOBID	Sequence	Used by the sp_cnc process and the compare, repair, and copy commands to provide a unique job ID.
SHAREPLEX_JOBS	Table	Used by the sp_cnc process and the compare, repair, and copy commands to store information about a job.
SHAREPLEX_JOB_STATS	Table	Used by the sp_cnc process and the compare, repair, and copy commands to store information about a job.
SHAREPLEX_JOBS_CONFIG	Table	Used by the disable jobs and enable jobs commands.
SHAREPLEX_LOB_CACHE	Table	Used by the Capture process when processing VARRAYs stored as LOB.
SHAREPLEX_LOBMAP	Table	Used by the Capture process to map LOBIDs and rows when a table with LOB columns does not have PK/UK logging enabled.
SHAREPLEX_LOGLIST	Table	Used by the Capture process to track inactive RAC instances.
SHAREPLEX_MARKER	Table	Used by the Read process when PK/UK logging is not enabled.
SHAREPLEX_OBJMAP	Table	Used by the activation and Capture processes to define the objects in replication.
SHAREPLEX_PARTITION_CACHE	Table	Used by the Capture process to map Oracle partition IDs to tables in replication.
SHAREPLEX_SYNC_MARKER	Table	Used by the copy command and the Read and Post processes to sync their operations.
SHAREPLEX_TRANS or SHAREPLEX_OPEN_TRANS	Table	Used by the Post process to store checkpoints and to mark transactions that were applied in a master-to-master configuration.

MKS Toolkit

On the Windows platform, SharePlex installs the MKS Toolkit® operating environment from Parametric Technology Corporation (PTC), formerly known as Mortice Kern Systems NuTCRACKER. This software enables SharePlex to be ported to all supported platforms in a uniform manner.

SharePlex users have no interaction with the MKS Toolkit software, other than to ensure that its service is running when the SharePlex service is running. The MKS Toolkit is installed in automatic startup mode by default when it is installed during SharePlex installation.

The default folder for MKS Toolkit is C:\Program Files\MKS Toolkit, but a different folder might have been selected during installation. The MKS Toolkit files must not be moved after they are installed.

SharePlex Registry Entries

On Windows systems, SharePlex installs the following Registry entries.

\HKEY_LOCAL_MACHINE\Software\Wow6432node\Quest Software\SharePlex: This contains the SharePlex environment information and is where any user-created variables must be entered, such as SP_SYS_VARDIR. Each instance of SharePlex is defined in the Registry as a port number, and each has its own set of environment variables.
\HKEY_LOCAL_MACHINE\Software\Wow6432node\Mortice Kern Systems: This contains Registry entries for the MKS Toolkit® operating environment.
\HKEY_LOCAL_MACHINE\Software\Wow6432node\Datafocus: This contains Registry entries for the MKS Toolkit® operating environment.
