4 Overview This dcument will describe: The high-level prcess fr cnfiguring the SAS Envirnment Manager Agent in a SAS Grid envirnment in which a shared directry has been used t deply SAS 9.4. A manual prcess fr cnfiguring the SAS Envirnment Manager Agent in a SAS Grid envirnment in which a shared directry has been used t deply SAS 9.4. The deply-ev-agents.sh script that has been develped t autmate the prcess f cnfiguring the SAS Envirnment Manager Agent in a SAS Grid envirnment in which a shared directry has been used t deply SAS 9.4. Caveats This dcument is fcused n SAS Grid deplyed n UNIX. This prcess des nt cver any f the manual pst-deplyment steps that must be run, such as starting the SAS Envirnment Manager Agents n the SAS Grid ndes. Hwever, the autmatin script des print a summary f the actins it perfrmed as well as any required pst-deplyment steps that must be perfrmed after the script successfully cmpletes. This infrmatin is printed t the screen just befre the script exits n a successful deplyment. This prcess des nt include creatin f SAS metadata sftware cmpnents fr newly created SAS Envirnment Manager Agents used by SAS Grid ndes. Assumptins 1. SAS has already been deplyed int a shared deplyment directry by running the SAS Deplyment Manager n the SAS Grid Cntrl Server. 2. All ther SAS Grid ndes have access t the shared deplyment directry via the same fully qualified path. 1

5 High-level prcess descriptin Stp the SAS Envirnment Manager Agent n the SAS Grid Cntrl Server. Fr every ther SAS Grid nde: Create a target directry fr the new agent. Cpy the agent directry structure int the target directry. Remve the agent data/ directry frm the target directry. Remve the agent lg/ directry frm the target directry. Create a backup f the agent prperty file in the target directry. Update the agent prperty file in the target directry. Create a backup f the SAS custm agent prperty file in the target directry. Link the SAS custm agent prperty file t the riginal SAS custm agent prperty file used n the SAS Grid Cntrl Server. Start the SAS Envirnment Manager Agent n the SAS Grid Cntrl Server Manual Prcess Assumptins and Ntes Envirnment variables are used in place f actual values fr the SAS Cnfiguratin Lev directry and the grid hst name t facilitate cpying and pasting the belw cmmands. The SAS Cnfiguratin directry (up t and including the cnfiguratin "Lev" directry) is lcated at $SAS_CONFIG. This prcess will nly cver a single SAS Grid nde. Additinal ndes wuld fllw a similar prcess. T clarify, when perfrming this prcess fr multiple ndes, the first and last steps (stpping and starting the riginal SAS Envirnment Manager Agent, respectively) nly ccur nce while all steps in between ccur fr every SAS Grid nde. The SAS Grid nde that we are cnfiguring the agent fr is $GRID_NODE. It is recmmended that the fully qualified hst name be used fr the actual value f $GRID_NODE. 2

Caveats The script is a wrk-in-prgress and may be updated in its current lcatin withut prir ntice. While it is expected that this script shuld wrk n any UNIX system with an sh r bash shell, the script has nly been tested and verified t wrk n a 64-bit Linux system. Usage In its mst basic frm, the script requires tw inputs: 1. The lcatin f the SAS Cnfiguratin directry (up t and including the cnfiguratin "Lev" directry). 2. A list f ne r mre SAS Grid ndes fr which t deply the SAS Envirnment Manager Agent. 4

8 T see the usage statement, run the script with the -h ptin: %./deply-ev-agents.sh -h Usage:./deply-ev-agents.sh [-n] [-q] -c SAS_CONFIG_DIRECTORY NODE1 [NODE2... NODEN]./deply-ev-agents.sh -V./deply-ev-agents.sh h Inputs The script takes a number f inputs. Sme f thse inputs are required and thers are ptinal. All f the ptinal inputs default t sane values. Sme inputs can be specified either via an envirnment variable r a cmmand line ptin. Fr thse inputs, the cmmand line ptin takes precedence if bth the cmmand line ptin and the envirnment variable are specified.
