Name

csinstall − allocates shared memory and semaphore resources for use by ULTRIX/SQL

Syntax

csinstall

Description

The csinstall command allocates shared memory and semaphore resources for use by ULTRIX/SQL. Only the ULTRIX/SQL system administrator can use csinstall.

The csinstall command uses the value stored in the ULTRIX/SQL environment variable II_LG_MEMSIZE to install ULTRIX/SQL shared memory and semaphore resources. If II_LG_MEMSIZE is not set in the ULTRIX/SQL symbol table, the size of shared memory segment for the ULTRIX/SQL locking and logging facilities defaults to approximately 200 Kbytes. The memory segment is created when csinstall is run and its size is fixed until the next time csinstall is run.  The II_LG_MEMSIZE variable is set when you start the dmfrcp process. The dmfrcp process reads the locking and logging parameters that were specified during configuration, calculates the maximum amount of memory needed to support those parameters, and sets II_LG_MEMSIZE to that amount (in bytes).

Note

If you reconfigure shared memory and semaphore resources using the −init option of the iistartup command, csinstall runs automatically as part of iistartup.
