Abstract: Hyperclusters are a cluster of clusters. Each cluster has associated with it one or more resource groups, and independent node failures within the clusters are handled by platform specific clustering software. The management of coordinated failovers across dependent or independent resources running on heterogeneous platforms is contemplated. A hypercluster manager running on all of the nodes in a cluster communicates with platform specific clustering software regarding any failure conditions, and utilizing a rule-based decision making system, determines actions to take on the node. A plug-in extends exit points definable in non-hypercluster clustering technologies. The failure notification is passed to other affected resource groups in the hypercluster.

Abstract: A method for maintaining the integrity of a backup database table on a secondary node against a continuously replicated and dynamically changing original database table on a primary node includes generating an original checksum of a segment of the original database table between a beginning record and an ending record. The checksum and identification data may be stored in an original control database table. The original control database table may be replicated to a backup control database table. Thereafter, a backup checksum of a segment of the backup database table between a beginning record and an ending record is generated. A comparison between the backup checksum and the original checksum is made in response to a triggering update to the backup control database table. Collisions by application generate transactions in the source and target databases may be detected despite the use of third party “black box” replication processes.

Abstract: The present invention provides a shunt for the flow of aqueous humor from the anterior chamber of the eye to Schlemm's canal. The device comprises at least one lumen and optionally has at least one anchor extending from the proximal portion within the anterior chamber to assist in placement and anchoring of the device in the correct anatomic position.

Abstract: The present invention provides a device and method for monitoring the flow of aqueous humor within the eye. The invention provides that the aqueous flow rate and/or pattern within the anatomical structures of the eye can be determined by monitoring a traceable component. Such determination provides diagnostic indications of the degree and location of ocular disease associated with aqueous outflow, such as glaucoma, and can further provide post-treatment indications of effectiveness.

Abstract: Shunt devices and a method for continuously decompressing elevated intraocular pressure in eyes affected by glaucoma by diverting excess aqueous humor from the anterior chamber of the eye into Schlemm's canal where post-operative patency can be maintained with an indwelling shunt device which surgically connects the canal with the anterior chamber. The shunt devices provide uni- or bi-directional flow of aqueous humor into Schlemm's canal.

Abstract: Stent devices and a method for continuously facilitating the flow of aqueous humor through Schlemm's canal where post-operative patency can be maintained with an indwelling stent device. The stent devices provide uni- or bi-directional flow of aqueous humor within and through Schlemm's canal.

Abstract: Catheter devices and methods for treating glaucoma and other eye diseases by expandable dilatation of Schlemm's canal and/or direct injection of medications into Schlemm's canal.
