Note:
Tasks in this section
are required only if you are changing the location of your GDS directory
on the system you plan to upgrade to AEM forms on JEE.
The global document storage (GDS) directory is used to store
long-lived files that are used within a process as well as critical
AEM forms on JEE product components. The lifetime of long-lived
files is intended to span multiple restarts of a AEM forms on JEE
system, and can span days and even years. These files may include
PDF files, policies, or form templates.
Long-lived
files are a critical part of the overall state of many AEM forms
on JEE deployments. If some or all long-lived documents are lost
or corrupted, the existing server may become unstable and unusable
for an upgrade. Input documents for asynchronous job invocation
are also stored in the GDS directory and must be available in order
to process requests.
You
must create the GDS directory before you initialize the AEM forms
on JEE database. See
5.5.1 Location of the global document storage directory
for information.
You
can reuse the existing GDS directory or copy it’s contents to a
new location.
5.5.1 Location of the global document storage directory
You configure the location of your GDS directory with Configuration
Manager after you install AEM forms on JEE. The GDS directory you
specify should be highly available and should have low access time
to enhance performance. If the GDS directory is on a shared network
drive, it is recommended that you specify the location in UNC style
as
\\computer_name\GDS
.
If
you changed the GDS location while installing AEM forms on JEE,
you can determine the location of the directory as follows:
-
Log in to Administration Console and click Settings >
Core System Settings > Configurations.
-
Note the location that is specified in the Global Document
Storage Directory box.
If you must change the GDS directory location after completing
the installation (see
AEM forms on JEE Administration Help
),
you should plan an appropriate location for the GDS directory.
Important:
Module deployment will fail on Windows
if the GDS directory is at the drive root (for example, D:\). For
GDS, you must make sure that the directory is not located at the
root of the drive but is located in a subdirectory. For example,
the directory should be D:\GDS and not simply D:\.
5.5.2 Sizing factors for the global document storage directory
The size of the global document storage directory depends
on expected AEM forms on JEE usage factors for the deployment. You
should allocate a minimum of 10 GB of disk space for the GDS directory.
While
upgrading to AEM forms on JEE from a previous version of LiveCycle,
you must factor in the existing GDS data while allocating space
for the GDS directory. This actual size required for the GDS directory
may be in excess of 10 GB.
The following factors also affect the sizing:
-
The typical volume of documents that LiveCycle processes.
Processing high volumes of documents requires a larger GDS directory.
-
The typical size of documents that AEM forms on JEE processes.
Processing large documents requires a larger shared GDS directory.
-
The complexity of documents that AEM forms on JEE processes.
Processing complex documents, such as documents that are processed
by multiple services that are part of AEM forms on JEE, require
a larger GDS directory.
5.5.3 Securing the global document storage directory
Access to the GDS directory must be secure. The long-lived
documents in this directory may contain sensitive user information,
such as information that requires special credentials when accessed
by using the AEM forms on JEE SDK or user interfaces.
Use a security method that is appropriate to your operating system.
It is recommended that only the operating system account that is
used to run the application server has read and write access to
this directory.
Note:
Deleting files or directories from the GDS directory
can render the AEM forms on JEE server inoperative.
5.5.4 Backing up the global document storage directory
The global document storage directory should be backed
up to allow administrators to restore AEM forms on JEE in case of
failure.
If the global document storage directory becomes unavailable
or is lost due to failure, AEM forms on JEE will not run until the
GDS directory and database are restored by a consistent back up
or AEM forms on JEE is reinitialized with a new installation.
