Previous Topic: NTHREADS=nNext Topic: Operating the Centera Access Server Task


TYPE=PRIMARY/SECONDARY/ONLY

A Centera server needs to run on every system that accesses reports stored on Centera storage.

PRIMARY

This server is to perform the input. Secondary servers are to make requests from it using XCF.

SECONDARY

This server does not perform input; instead, requests for report blocks are made using XCF to the primary server.

ONLY

This is the one and only server; it will perform all of its own input, and no XCF communications are established.

The default is ONLY.

Note: Primary and Secondary servers are to be used when TCP/IP access is not available on all systems. If primary and secondary servers are not used, ONLY should be used on all systems.

Sample

This example shows the JCL for a started task that initiates the Centera access server:

//SARCAS PROC TYPE=ONLY      
//SARCAS EXEC PGM=SARCAS,TIME=1440,
// PARM=('TY=&TYPE', TYPE is ONLY by default, changeable at startup
// 'CA=CENT',        CASTNAME is CENT
// 'CO=XCF',         COMM is XCF
// 'MA=600',         MAXIDLE is 10 minutes
// 'MI=1',           MINIDLE is 1 seconds
// 'NB=9000',        NBUF is 9000 buffers
// 'NREA=16',        NREAD is 16 reads at a time
// 'NREQ=200',       NREQ is 300 process request entries
// 'NT=12'),         NTHREADS is 12 threads (active reports)
//STEPLIB DD DSN=CAI.CVDELOAD,DISP=SHR
//        DD DSN=CAI.CEN31544.PROGLIB.OPT,DISP=SHR
//SYSUDUMP DD SYSOUT=A
