Prerequisites
This document assumes an environment that includes the following:
Windchill PDMLink 11.0 M030 with Visualization is configured and installed with the following:
The latest Windchill CPS
PTC HTTP Server (powered by Apache)
Oracle 11gR2 [11.2.0.4] and Oracle 12c [12.1.0.2]
or
SQL Server 2012, SQL Server 2014, and SQL Server 2016.
* 
32-bit and 64-bit Oracle 11g Enterprise Edition and Standard Edition 2 are supported.
64-bit Oracle 12c Enterprise Edition and Standard Edition 2 are supported.
Appropriate language, if using localized PTC FlexPLM
Windchill Help Center installed and configured
ImageMagick (See ImageMagick for PTC FlexPLM for installation and configuration details.)
In addition, when installing Windchill PDMLink 11.0 M030, you can enable extended character sets by selecting the appropriate checkbox. This setting allows you to use languages other than English. You can verify the use of extended character sets by checking the wt.db.maxBytesPerChar setting.
PTC FlexPLM system environment is running with a single method server.
WinZip or Zip Compression Tool for UNIX is installed.
To manage CAD data or part structures, you must deploy and install the RFA GWT modules using the readme instructions provided in the RFA GWT CD or ZIP file.
You can obtain this file from the PTC software download site and PTC Technical Support. The RFA GWT modules are part of the ZIP file that contains the full PTC FlexPLM download.
These modules are optional and can be installed and deployed at a later time if needed.
If you are installing on AIX, install and configure the Windchill Help Center using the Windchill Installation and Configuration Guide before installing PTC FlexPLM.
If Windchill PDMLink was installed with an Oracle database using extended multi-byte characters, use the <Windchill>\db\sql3 folder for all SQL scripts. If multi-byte characters were not installed, use the <Windchill>\db\sql folder for all SQL scripts, which is for non‑extended multi-byte characters.
To determine which characters were used during installation, check the wt.db.maxBytesPerChar setting.
If this setting is set to 1, then extended multi-byte characters are not enabled and you must use the <Windchill>\db\sql folder.
If it is set to 3, then extended multi-byte characters are enabled, and you must use the <Windchill>\db\sql3 folder.
* 
The SQL folder is represented as sql* throughout this document, and represents the appropriate folder for your installation.
If Windchill PDMLink was installed with a SQL server, use the <Windchill>\db\sqlserver folder for all SQL scripts.
The JVM time zone for the Embedded Servlet Engine and Windchill instances must be set to GMT time, as all data is saved as GMT. The date and time displayed in the user interface is based on the user’s browser locale. Only the JVM for the PTC FlexPLM instance must be modified. Do not modify the JVM for the entire server, as this interferes with other applications. PTC FlexPLM is configured out-of-the-box to force GMT time zones at the persistence layer.
New installations must use modeled sequences. Using the com.lcs.wc.db.useModeledSequences=false property setting on new installations is unsupported and causes an error.
This property is provided for backwards compatibility. Only apply this property to upgraded systems that contain non-modeled sequences in historical Oracle databases. Non-modeled sequences are not supported in SQL server databases.
