原因

Customer has set the value for BAR_MAX_BACKUP as 0 in the onconfig file which means unlimited backup streams. The specific Informix database has 47 dbspaces and hence when backup (database or logical log backup) or restore starts the database server creates many onbar processes. The same situation occurs during restore as well. That results in a stalled situation and some of the threads gets failed after retrying as per the retry value set for BAR_RETRY.

 

解決方法

Setting BAR_MAX_BACKUP value as 10 in the onconfig file (location: /infx/inst/<DB-Name>/informixdir/etc/onconfig.xxx) resolved the problem. We can go with a lower value, for example, 4 or 6 depending on the situation.
