Configuring Memory Allocation

If you are using Precision Bridge version 6.0 or later, you can specify the initial memory and maximum memory that Precision Bridge can use by updating the file called PrecisionBridge.l4j.ini (in the install folder for Windows installations). The default configuration is shown below.

-Xms gives the initial memory allocation to Precision Bridge (512m = 512MB)

-Xmx gives the maximum memory allocation to Precision Bridge (1024m = 1024MB)

You can specify the initial memory and the maximum memory that the Precision Bridge application will use. 

 These may need to be increased from the defaults if you run a large project, particularly one containing:

1. attachment data mappings;
2. a very large number of records (> 1,000,000)
3. a large number of reference mappings or inclusion filters, particularly if large volumes of data are being migrated.

You should be sure that your machine can support the defined memory requirements to avoid memory allocation issues when starting up Precision Bridge.

Optionally you can also define other Java Virtual Machine parameters to be passed on start up.  Use this option only if you are experienced in JVM configuration. 

Once you have made changes to this file, you will need to restart the Precision Bridge tool for them to take effect.
