What's the most ACID settings with H2 Database? -


we have product running issues because of 2 power off.

the h2 database on 1.3.x version intended update improve resiliency , durability, specially diminishing database corruption chances because our client upset db crashes , needs solution in order not buy proprietary expensive license.

it 24/7 governmental health system 20 simultaneous transactions in worst case. database 4gb , 4 months old, bigger.

the server windows 2012 , use new resilient filesystem format. last option install bsd zfs filesystem mature.

we update h2 1.4.x using mvstore=false; mvcc=false; lock_timeout=10000; lock_mode=3; autocommit=on; delay_transaction=-1?? , trying checkpoint sync , /or call fsync() on every insert update delete operation.

as fsync() (if works on win2012) slow write operations, using ssd not discarded.

the java ee application running on same server, best run in embedded mode?

we can use second server cluster copy because need online backups, think software "select ... offset" in autonomous way.

we need stable , reliable way operate no database crashes. @ file size, hdd take longer, using split alternative.

the server 4 core xeon 16gb ram, improve caches , use g1cc garbage collection.

another option using 1 connection queue pool guarantee 1 transaction @ once.

there autovacuum option postgresql?

so, there many options need make best choice.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
