Abstract
The invention discloses a method for improving the availability of a DB2 DPF. The method is used for the DPF including N nodes and comprises steps of: allocating NAS network storage to the N nodes in order that a sqllib control file in the DPF is stored in the NAS network storage; creating M failed resource sets; dividing the N nodes into M groups; configuring partition resources corresponding to M groups of nodes to the M failed resource sets one to one; and when any one of the N nodes is faulted, transferring the failed resource set corresponding to the faulted node to any other normally-operating node. An application of a client may acquire the partition resource corresponding to the faulted node by accessing the node provided with the failed resource set corresponding to the faulted node, thereby guaranteeing that data service can be still normally provided for an external unit when a single node is faulted and improving the availability of DPF.

Embodiment
Below in conjunction with in the embodiment of the present invention
accompanying drawing, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of method for improving DB2DPF availability, being applied to DB2DPF, DB2DPF comprises N number of node, wherein, N be not less than 2 integer; See
fig. 1shown in, the method comprises:
Step S101: distribute the NAS network storage to N number of node, deposits sqllib control documents in DB2DPF to utilize the NAS network storage.
It should be noted that, in existing DB2DPF, sqllib control documents leaves on any one node of DPF, then (NFS is served by the NFS of this node, i.e. NetworkFileSystem, NFS) give other nodes by sqllib catalogue sharing, like this, after the NFS service of this node is broken down, then the sqllib catalogue shared by NFS service will cannot be completed carry because of ping less than NFS service and conciliate the handoff procedure hung.For this problem, the embodiment of the present invention is by leaving in the NAS network storage by sqllib control documents, now in itself and DPF, the NFS service fault state of arbitrary node has nothing to do, also be, now the malfunction of DPF arbitrary node cannot impact the carry of sqllib catalogue or solution extension, thus correspondingly solves the problems of the prior art.
Step S102: share for N number of peer distribution and store, and build cluster between N number of node.
Step S103: create M stale resource will group, wherein, M is the positive integer being not more than N.
Step S104: N number of node is divided into M group, obtains M group node, and wherein, each group node at least comprises a node; Respectively the partitioned resources in M group node corresponding to each group node is configured to M stale resource will group correspondingly.
Step S105: when after any one one malfunctions in N number of node, the stale resource will group corresponding to the node this broken down is mounted on other arbitrary nodes that can normally work.
Be understandable that, in the present embodiment, between any two nodes, all ensure internodal synchronousness by configuration NTP time server (NTP, i.e. NetworkTimeProtocol, NTP (Network Time Protocol)); In addition, need to carry out business network card binding between any two nodes, and SSH (SSH, i.e. SecureShell, the safety shell protocol) mutual trust of root user and instance user need be configured.
Method disclosed in the embodiment of the present invention is applied to the DB2DPF including N number of node, and the method first gives above-mentioned N number of peer distribution NAS network storage, to utilize the NAS network storage to deposit the sqllib control documents in DPF, on this basis, share for above-mentioned N number of peer distribution and store, and build cluster between this N number of node, then create M stale resource will group, accordingly, N number of node is divided into M group, each group node at least comprises a node, then respectively the partitioned resources in M group node corresponding to each group node is configured to M stale resource will group correspondingly, when after any one one malfunctions in N number of node, stale resource will group corresponding to the node this broken down is mounted on other arbitrary nodes that can normally work, like this, the application of client can by accessing the node of the stale resource will group of this carry corresponding to malfunctioning node, thus get the partitioned resources configured in stale resource will group corresponding to above-mentioned malfunctioning node, also the partitioned resources corresponding to malfunctioning node is namely got, thereby eliminate the Single Point of Faliure of DPF, ensure that DPF still normally outwardly can provide data, services when there is Single Point of Faliure, thus improve the availability of DPF.
The embodiment of the invention discloses a kind of method for improving DB2DPF availability specifically, relative to a upper embodiment, the present embodiment has done further optimization to technical scheme.Concrete:
In order to improve the performance of database further, a upper embodiment step S102 share the process of storage for N number of peer distribution after can also comprise: the data base administration parameter of DB2DPF and database parameter are optimized.
Further, step S104 respectively the partitioned resources in M group node corresponding to each group node is configured to the process of M stale resource will group correspondingly after can also comprise: the partitioned resources configured in M stale resource will group carries out monitoring resource.
In addition, step S104 respectively the partitioned resources in M group node corresponding to each group node is configured to the process of M stale resource will group correspondingly after can also comprise: Floating IP address and network interface card are monitored.
The embodiment of the invention discloses a kind of system for improving DB2DPF availability, being applied to DB2DPF, DB2DPF comprises N number of node, wherein, N be not less than 2 integer; See
fig. 2shown in, this system comprises:
