All,
my multithreaded C-Application crashes when it executes two SQLs at the
same time. I use the C-API from IBM (ODBC-compatible) to execute my SQL
queries.
When two threads are executing a SQL-Statement at the same time (i. e.
"SET CURRENT SQLID = xxx"), my appl crashes and gives me the message
CEE0814S INSUFFICIENT STORAGE WAS AVAILABLE TO EXTEND THE STACK.
Per default a thread gets 131072 (128 K) Bytes stack space and I've
enlarged it to 1048576 Bytes (1 MB) but nothing changed.
I'm using so called "NULL Connects" and my DSNAOINI contains:
[COMMON]
MVSDEFAULTSSID=DB2E
MULTICONTEXT=1
CONNECTTYPE=1
THREADSAFE=1
TRACEFILENAME=DD:DSNAOTRC
MAXCONN=0
[DB2E]
MVSATTACHTYPE=CAF
PLANNAME=MYPLAN
The ODBC Environment Handle get allocated in the main-thread and the
connections, connection Handles and statement handles get allocatd
within the threads...
Any idea?!?!?!?!?
Thank you,
Michael
