Abstract
Abstract Complex resource configurations often exist in multiprocessor systems. Because of this, competing access to a specific resource configuration by a plurality of processors results in coordination problems. The invention solves the problems by the fact that a central protection (security) table is introduced and that a processor has to leave its processor number there with a specific protection number, if it wants to obtain control over the resource configuration associated with this protection number. <IMAGE>

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
114 words
Method for a plurality of user instances to edit
connections or transactions, according to which a) every connection or transaction is allocated a
respective security number which is concomitantly
stored for every resource used for the connection
or transaction, b) a user instance's access to a used resource is
preceded by the security number concomitantly
stored for this resource being withdrawn and a
central storage means attempting to store the user
instance's incarnation number for this security
number, c) any attempt by a user instance to access a used
resource is rejected if, during the attempt at
storage, it is established that another user
instance's incarnation number is already stored
for this security number.
Claim 2
Dependent Claim
37 words
Method according to Claim 1, characterized
in that the central storage means is in the form of a
table, with the user instance's incarnation number
being stored at that table location which corresponds
to the security number.
Claim 3
Dependent Claim
18 words
Method according to Claim 1 or 2, characterized
in that the security numbers (SID) provided are
allocated cyclically.
