Resolving APPC or CPI-C Application Problems
If you are having problems with an APPC or CPI-C applications, do the
following:
Step 1. Check that the application is correctly installed
Step 2. Check that the mode, LUs and link required are correctly configured
Step 3. If a problem occurs when the application originates the conversation do
the following:
Step 1. Check that the link is active (this may happen on demand). Refer to
“Check Communication with Other SNA Nodes”
Step 2. Check that the relevant session is started (this may happen on demand)
Step 3. If a problem occurs when the application receives an incoming
conversation request, do the following:
Step 1. Check that the link is active (this may happen on demand if the link is
configured as incoming)
Step 2. Check that the relevant session is started (this may happen on demand)
Step 3. If the receiving application is dynamically loaded (invokable), also check
that the TP configuration information has been configured correctly
(refer to the HP-UX SNAplus2 Administration Guide for more
information about configuring TP information).
Step 4. Verify that the session limit is sufficient for the number of applications
required.
Step 5. Check that you are not mixing single–session and parallel–session
modes on an LU-LU pair.
Step 6. The APPN architecture does not support independent LU 6.2 (parallel
sessions) across an LS (typically SDLC) that is established without XID
exchange (that is, with just SNRM and UA). Therefore, if the host does
not send XIDs, independent LU 6.2 cannot be used.
Step 7. Check the correct allocate type (for example, an immediate allocate
needs a contention winner session).
Step 8. For CPI-C applications, set the local LU name (using the snapadmin
