whether or not the freeze map can be concurrently access by multi-processes?

Yunqiao YinYunqiao Yin Member Yin YunqiaoOrganization: BaosteelProject: real time process control system ✭✭
In the Ice manual,I only found that if concurrence access a map from multi-threads,different freeze map connections must be used. But I want to know if I access a map from different processes concurrently,is it OK?
PS: Can you provide any consult ,technology supports or trainning in China,especially in Shanghai?

Yours Sincerely

    Hi Yunqiao Yin,

    With Freeze, you cannot access the same Berkeley database from several processes concurrently. This is a limitation in Freeze, and I suspect it would be fairly easy to remove for Freeze maps since the underlying database system (Berkeley DB) allows several processes to access the same database concurrently.

    Please contact us at [email protected] if you'd like to sponsor such an enhancemenent, and for information on consulting services in China.

    Best regards,
