SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThese topics contain the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™.The HCL OneDB™ Guide to SQL: Reference contains the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™. These topics also include information about the stores_demo, sales_demo, and superstore_demo databases that are included with HCL OneDB™.
Environment variablesVarious environment variables affect the functionality of your HCL OneDB™ products. You can set environment variables that identify your terminal, specify the location of your software and define other parameters.
Environment variables in HCL OneDB™ productsThe topics that follow discuss (in alphabetic order) environment variables that HCL OneDB™ database server products and their utilities use.
ISM_COMPRESSION environment variableUse the ISM_COMPRESSION environment variable to specify whether the HCL® OneDB® Storage Manager (ISM) should use a data-compression algorithm to store and retrieve data.

ISM_COMPRESSION environment variable

Use the ISM_COMPRESSION environment variable to specify whether the HCL® OneDB® Storage Manager (ISM) should use a data-compression algorithm to store and retrieve data.

setenvISM_COMPRESSION { TRUE | FALSE }

If ISM_COMPRESSION is set to TRUE in the environment of the ON-Bar process that makes a request, the ISM server uses the data-compression algorithm.

If ISM_COMPRESSION is set to FALSE or is not set, the ISM server does not use compression.
