Adding resource manager configuration information for Informix

 

The next step is to modify the configuration information for the queue manager, as described in Adding configuration information to the queue manager, to declare Informix as a participant in global units of work.

• On Windows and Linux (x86 platform) systems use the WebSphere MQ Explorer. Specify the details of the switch load file in the queue manager properties panel, under XA resource manager.

• On all other systems specify the details of the switch load file in the XAResourceManager stanza in the queue manager's qm.ini file.

Figure 1 is a UNIX sample, showing an XAResourceManager entry where the database to be coordinated is called mydbname, this name being specified in the XAOpenString:

Figure 1. Sample XAResourceManager entry for Informix on UNIX platforms

XAResourceManager:
  Name=myinformix
  SwitchFile=infswit
  XAOpenString=mydbname
  ThreadOfControl=PROCESS

In Figure 1, ThreadOfControl is specified as PROCESS. This value is required for the queue manager to use the Informix XA switch-load file. However, also note that the supported levels of Informix do not allow multi-threaded XA applications.
