Understanding Enterprise Server Cleanup for IBM i
When JD Edwards EnterpriseOne ends abnormally, you might need to manually perform cleanup tasks on the IBM i enterprise server. Inter-process Communication (IPC) structures might not be cleaned up after an execution of ENDNET, which might cause further problems when you start JDENet. If the IPC structures are not properly removed by ENDNET, you can manually remove them. IPC structures might become locked by an interactive job. For example, you might have to sign off and sign back on to perform a successful cleanup.
The JD Edwards EnterpriseOne IBM i server is shipped with the DSPIPC and CLRIPC commands, which enable you to display the IPC-related information and to remove IPC structures.
If tracing is turned on in addition to IPC, you should clear the jde.log and jdedebug files. This action keeps the files from becoming too large and removes old messages from it.
