  • Publication number: 20210240579
    Abstract: Systems and methods to utilize a tablespace to export to a native database recovery environment are described. The system receives file information and script information at a source host that operates in a native database recovery environment. The file information and the script information are received from a backup host that utilizes foreign snapshot files and foreign incremental files for storing the file information. The file information includes native snapshot files and native incremental files. The script information includes one or more scripts that execute, at the source host, to perform operations comprising: mounting the directories; opening an auxiliary database; restoring a tablespace in the auxiliary database; recovering the tablespace in the auxiliary database based on the native incremental files; exporting the tablespace metadata information from the auxiliary database; recovering the tablespace in the database based on the tablespace metadata information; and unmounting the directories.

  • Publication number: 20210240581
    Abstract: Systems and methods to export a database to a native database recovery, environment are described. The system includes a native database recovery environment that includes a target host. The target host receives file information and script information, over a network, via directories from a backup host. The backup host utilizes foreign snapshot files and foreign incremental files to store the file information in the foreign database recovery environment. The file information includes native snapshot files and native incremental files. The script information includes scripts that are executed by the target host in the native database recovery environment. The target host executes the scripts to mount the directories, open the database, restore the database, recover the database to a point-in-time, and unmount the directories.

  • Publication number: 20210240661
    Abstract: Systems and methods to optimize utilization of a tablespace for export from a native database recovery environment are described. The system receives a database from a source host, operating in a native database recovery environment, at a backup host operating in a foreign database recovery environment. The foreign database recovery environment utilizes foreign snapshot files and foreign incremental files for storing the database. The system receives a tablespace identifier that identifies a tablespace and a point-in-time that identifies file information for export from the backup host to the source host. The backup host initiates a job to generate script information; create directories; materialize the file information; utilize an auxiliary database to generate tablespace metadata information; and communicate the tablespace metadata information and the script information and the file information, via the directories, and over a network, to the source host, to enable the source host to recover the tablespace.

  • Publication number: 20210240580
    Abstract: Systems and methods to export a database from a foreign database recovery environment are described. The system includes the foreign database recovery environment that includes a backup host that receives the database from a source host operating in a native database recovery environment. The backup host utilizes foreign snapshot files and foreign incremental files for restoring the database. The backup host receives export information. The export information includes a target host, a point-in-time, and a database name identifying the database for export from the backup host to the target host. The backup host initiates a job that generates script information, creates directories, materializes file information, and communicates the script information and the file information, via the directories, to the target host.

  • Publication number: 20210188521
    Abstract: A soft-sided insulated container that has a rigid closure. The rigid closure has a first closure interface that is a passive friction fit in which one part wipes another. The rigid closure has a second closure interface that is an active closure in which a mechanical device, such as a latch or clamp, is used positively to energize a closure between different parts of the closure. The soft-sided insulated container has a soft-sided external casing, and a rigid internal liner that includes a mating rigid lid. There is a releasable securement that holds the liner in engagement with the casing, but that can be released to permit the casing to be extracted from the liner. The releasable securement is a one-way passively engageable securement.

  • Patent number: 8592625
    Abstract: The present invention relates to a process for resolving S-3-(Aminomethyl)-5-methylhexanoic acid, which adopts benzoyl-L-glutamic acid, 4-methyl benzoyl-L-glutamic acid, benzene sulfonyl-L-glutamic acid or 4-methyl benzene sulfonyl-L-glutamic acid as a resolution agent to make a first resolution to racemic 3-aminomethyl-5-methylhexanoic acid, and adopts the resolution agent same to that of the first resolution to make a second resolution to the first resolution product to obtain the second resolution product, thus the resolution salt product is obtained, and further hydrolyzed by an acid, the resolution agent is extracted to be separated, the pH is adjusted to be neutral, the product S-3-(Aminomethyl)-5-methylhexanoic acid, i.e.
