Pre-initialization environments are generated on at least one hardware processor for running incoming applications. Resource usage of resources configured for the pre-initialization environments in running the incoming applications is monitored. Automatic tuning of a pre-initialization environment among the pre-initialization environments is deactivated, responsive to determining based on the resource usage of resources configured for the pre-initialization environment, that the pre-initialization environment is maintaining a threshold level of efficiency. Automatic tuning of the pre-initialization environment among the pre-initialization environments is activated, responsive to determining based on the resource usage of resources configured for the pre-initialization environment, that the pre-initialization environment is overloaded. Automatic tuning of the pre-initialization environment among the pre-initialization environments is activated, responsive to determining, based on the resource usage of resources configured for the pre-initialization environment, that the pre-initialization environment is idle.

Global variables are shared between programs associated with different addressing modes. A first program of an application records an allocated address to a global variable in a global variable sharing area (GVSA). The first program is associated with a first addressing mode. The first program specifies the global variable to be shared across different addressing modes. An address of the GVSA is passed to a second program of the application that is loaded after the first program has been loaded. The second program is associated with a second addressing mode different from the first addressing mode. The second program also specifies the global variable in the second program to be shared across different addressing modes. The second program retrieves the allocated address to the global variable from the GVSA based on the address of the GVSA. The second program accesses the global variable based on the retrieved allocated address.

Sharing global variables between addressing mode programs

A method, including: monitoring resource utilization of an operating system (OS) with applications utilizing larger pages; determining the monitored resource utilization is greater than a threshold resource utilization; in response to the determining the monitored resource utilization is greater than a threshold resource utilization, determining a respective larger pages index value for each of the applications utilizing larger pages; and turning off larger pages utilization of a subset of the applications utilizing larger pages, wherein the subset comprises a predefined number of the applications utilizing larger pages that have highest determined larger pages index values.

A computer-implemented method, system and computer program product for improving accuracy and efficiency of auditing databases. A table, list or index of a database is analyzed to identify metadata, which includes time series data, user data, an Internet Protocol address and operation data. The identified metadata is associated with the corresponding record or row of the table, list or index from which the metadata was extracted. A determination is then made as to whether to record a raw data image associated with the record or row of the analyzed table, list or index based on the corresponding data operation. The identified metadata as well as the recorded data images, if any, are stored in a structured audit log. Auditing information is then obtained from a structured audit log based on matching the record or row identifier (RID) associated with the query with the RID associated with the structured audit log.

Utilizing a structured audit log for improving accuracy and efficiency of database auditing

In a first aspect of the invention, there is a computer-implemented method including: generating, by one or more processors, dependency version information for a target software application, based on activity of a compiler registered with an event handler; generating, by the one or more processors, one or more dependency sections with a dependency list for the target software application, wherein the dependency list incorporates the dependency version information; and building, by the one or more processors, a software package with the one or more dependency sections with the dependency list for the target software application.

Automatic precision dependencies management

A method, including: identifying static application features of an application; identifying resource access features of the application; labeling a translation lookaside buffer (TLB) miss threshold of a runtime feature of the application; determining utilization of larger pages during the runtime based on the TLB miss threshold; and setting the TLB miss threshold based on the determined utilization of the larger pages.

Dynamic tuning of larger pages during runtime

A computer-implemented method includes creating a first file control block in a primary runtime environment with a first addressing mode and a second file control block in a secondary runtime environment with a second addressing mode, where both the first file control block and the second file control block describe a status of a first file of a caller program in the primary runtime environment. The parameters of the first file of the caller program in the primary runtime environment are passed to a target callee program in the secondary runtime environment. An anchor is added in the first file control block as a link to the second file control block. The first file control block are the second file control block synchronized with updates to the first file in the primary runtime environment and the passed parameters of the first file in the secondary runtime environment.

Cooperative input/output of address modes for interoperating programs

Methods, systems, and computer program products for de-duplicating data in executable files in a container image are disclosed. The method may include receiving a request to read a file in a first layer in a container image including a plurality of layers, wherein the file is a delta file which is from an updated executable file based on a base executable file, the base executable file is in a lower layer than the first layer in the container image, and the delta file includes block mappings between the updated executable file and the base executable file and different data between the two files, and blocks included in the two files are based on respective file structure. The method may also include restoring the updated executable file based on the delta file and the base executable file. The method may further include returning data in the updated executable file.
