Description

After IGNITE-6030 data page evictions are broken if in-memory caches are mixed with persistence-enabled caches.
The problem is in page eviction tracker creation code:

        if (plc.getPageEvictionMode() == DataPageEvictionMode.DISABLED || CU.isPersistenceEnabled(cctx.gridConfig()))
            return new NoOpPageEvictionTracker();

We should check not the global configuration, but the data region configuration.
