SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThe 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.
THREADLIB environment variable (UNIX™)

THREADLIB environment variable (UNIX)

Use the THREADLIB environment variable to compile multithreaded applications. A multithreaded application lets you establish as many connections to one or more databases as there are threads. These connections can remain active while the application program executes.

The THREADLIB environment variable indicates which thread package to use when you compile an application. Currently only the Distributed Computing Environment (DCE) is supported.

The THREADLIB environment variable is checked when the -thread option is passed to the script when you compile a multithreaded application. When you use the -thread option while compiling, the script generates an error if THREADLIB is not set, or if THREADLIB is set to an unsupported thread package.
