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.
PSORT_NPROCS environment variableThe PSORT_NPROCS environment variable enables the database server to improve the performance of the parallel-process sorting package by allocating more threads for sorting.
Default PSORT_NPROCS values for detached indexes

Default PSORT_NPROCS values for detached indexes

If the PSORT_NPROCS environment variable is set, the database server uses the specified number of sort threads as an upper limit for ordinary sorts. If PSORT_NPROCS is not set, parallel sorting does not take place. If you have a single-CPU virtual processor, the database server uses one thread for the sort. If PSORT_NPROCS is set to 0, the database server uses three threads for the sort.
