This topic explains how to get started with z/OS®
Explorer and the IMS™
Configuration Manager
Eclipse plug-in.
Before you begin
For large IMS topologies, the
IMS
Configuration Manager
Eclipse plug-in can often present large amounts of
parameter, resource, or type-2 command response data from requests whose scope extends across many
IMS systems and IMSplexes. If when using the
IMS
Configuration Manager
Eclipse plug-in with
z/OS
Explorer you encounter an out of memory condition where the Java™ heap space has been exhausted due to large volumes of data
being returned, try increasing the maximum java heap size to rectify the issue. To do this:
- Open the zosexplorer.ini file (or eclipse.ini file as applicable) located in the z/OS
Explorer installation directory.
- If present, remove option -XX:MaxPermSize=xxxx.
- On a new line, add option -Xms256M. This sets the minimum heap size to 256
MB.
- On a new line, add option -Xmx4096M. This sets the maximum heap size to 4096
MB.
- Save the file and restart your z/OS
Explorer.
If you continue to receive out of memory errors after this change, increase the maximum value
as required and try again. To monitor the heap size, select and then select
Show heap status.
Procedure
- Double-click the z/OS
Explorer shortcut.
- Select .
- Select IMS
Configuration Manager,
and then click OK.
- Follow the prompts to complete the User
ID and Password fields using the
TSO credentials you normally use when using the IMS
Configuration Manager ISPF dialog.
What to do next
The first time that the
IMS
Configuration Manager Eclipse plug-in is run,
none of your systems are displayed. See
Connecting to a Common Services Library server to connect the
IMS
Configuration Manager Eclipse plug-in with
one or more running instances of the
Common Services Library server.
