Is there any sub service/ parent service that STAF framework can provide? Lu From: Sharon Lucas [mailto:luc...@us.ibm.com] Sent: Tuesday, June 30, 2009 11:03 AM To: Lu Yu Subject: RE: [staf-users] How to share memory between different services No, all STAF service request options are strings and all STAF service results are strings (e.g. no Java objects are passed -- though, you can create a marshalled data string that can consist of Strings, Lists, and Maps). Perhaps what you're really asking is a Java question, not a STAF question. How would you pass data from one Java application to another (without STAF involved)? -------------------------------------------------------------- Sharon Lucas IBM Austin, luc...@us.ibm.com (512) 286-7313 or Tieline 363-7313 Lu Yu <l...@vmware.com> 06/30/2009 12:58 PM To Sharon Lucas/Austin/i...@ibmus cc Subject RE: [staf-users] How to share memory between different services Sharon Connection anchor is just an example, it is a class object in the internal API..Never mind. So you mean that I can use STAF Queue service to pass any object from one service to another service? Thanks again!

Then that STAF handle can submit a GET WAIT request to the QUEUE service on the local machine to get messages off its queue. I don't know what you mean by "create anchor". -------------------------------------------------------------- Sharon Lucas IBM Austin, luc...@us.ibm.com (512) 286-7313 or Tieline 363-7313 Lu Yu <l...@vmware.com> 06/30/2009 12:35 PM To Sharon Lucas/Austin/i...@ibmus cc "staf-users@lists.sourceforge.net" <staf-users@lists.sourceforge.net> Subject RE: [staf-users] How to share memory between different services Sharon Thanks for your reply. Here is what I want: We have 3 services implemented in STAF by Java: VM, Host, Setup. All these services have some common info such as connection anchor. But currently, when we use VM service, we have to create anchor for VM, using Host service, we need to create another anchor for Host. Ideally, these two anchors are same, but since VM and Host service are in different memory, we can not re-use VM anchor for Host service. We are now thinking of way to build a main (common) service which handles all the common information such as anchor across all services. When needed for other services, we will load them. But all the loaded services can share the same information in main service. Can you please let me know what is the best way to do it Thanks Lu From: Sharon Lucas [mailto:luc...@us.ibm.com] Sent: Tuesday, June 30, 2009 8:30 AM To: Lu Yu Cc: staf-users@lists.sourceforge.net Subject: Re: [staf-users] How to share memory between different services Are these STAF Java services you have written? Are you asking how to run them in the same JVM? If so, just make sure when the Java service is registered that they are all registered using the same JVMName option (which defaults to STAFJVM1 if OPTION JVMNAME=<JVMName> is not specified when registering a STAF Java service). If this isn't what you're asking, please provide more information on what you are trying to do. -------------------------------------------------------------- Sharon Lucas IBM Austin, luc...@us.ibm.com (512) 286-7313 or Tieline 363-7313 Lu Yu <l...@vmware.com> 06/30/2009 02:19 AM To "staf-users@lists.sourceforge.net" <staf-users@lists.sourceforge.net> cc Subject [staf-users] How to share memory between different services Hi I am running STAF Framework in VMware. I have a question regarding sharing memory between different services. The problem I have is that we have maintained 4 different staf services (vmware internally developed service). In order to reduce the file size and memory usuage, we want to have a main service which has all shared information, when needed loading other services, the service loaded later can re-use the shared information in the main service. Can anyone shed a light on me of how to implement it? Thanks!
