This document helps the user to migrate CMS DB from SQLAnywhere to HANA Database where BOE is installed in Linux/Unix environment.

To make it simple I have divided the migration into two phases where Phase 1(Configuration Phase) deals with the configuring the required settings for migration and Phase 2(Migration Phase) deals with the actual migration.

Phase 1: Configuration Phase                     

                       In this phase we install the HANA client, configure the DSN, which is explained in detail below.

                            Step 1: Install HDB Client in the machine where BOE is installed.

                            Step 2: Using the below command copy libodbcHDB.so file from HDB Client directory to linux_x* directory.

                                  cp <HDB_Client_Install_Directory>/libodbcHDB.so<BOE_Install_Dir>/sap_bobj/enterprise_xi40/linux_x64/

                              cp <HDB_Client_Install_Directory>/libodbcHDB.so<BOE_Install_Dir>/sap_bobj/enterprise_xi40/linux_x86/

                             Step 3: Add the details of HANA server in odbc.ini which is present in <BOE_Install_Dir>/sap_bobj/enterprise_xi40/

                                  Below is the screenshot, which has details of HANA driver

                                  Note: ServerNode Value should be ServerNode=<HOSTNAME OF HANASERVER>:3<INSTANCENUMBER>15

                                                                                               echo $ODBCINI

                                          Note: Output should be: <BOE_Install_Dir>/sap_bobj/enterprise_xi40/linux_x64/

Phase 2: Migration Phase

                            In this phase, we perform the actual migration using cmsdbsetup.sh script.

                                 Step 1: Run cmsdbsetup.sh script present in <BOE_Install_Dir>/sap_bobj/

                                                                   ./ cmsdbsetup.sh

                                 Step 2: Specify the name of the node and press enter. In this example "lnxsuse11x64" is the name of the node.

                                 Step 3: You need to stop the node before migration so select option 3 to stop the node.

                                 Step 4: Select option 4 "copy" for Database Copy(by default it will be "update").

                 Step 5: It will show a warning message that this operation will deleted BIP tables in destination DB. Select option 3 "Yes"(by default it will be "No")

                         Step 6: It will prompt whether you need current DB(SQLAnywhere) as destination database. You need to select option 2 "No"(by default it                                            will be "Yes")

                                        Note: If you choose yes it will delete all BIP tables from current DB. In this our destination DB is HANA so select option 2.

                        Step 7: Select option 8 “SAP HANA” as destination database.

                        Step 8: Enter the ODBC DSN for connecting HANA DB(This values should be same as values entered in odbc.ini file). In this                                                             example “Hana_Migration” is DSN name for HANA DB.

                        Step 12: Now you need to specify Source CMS database. In this case you need to select option 2 “SQLAnywhere”.

                        Step 13: Enter the ODBC DSN for connecting SQLAnywhere DB(This values should be same as values entered in odbc.ini file).

                                      In this example “BI4_CMS_DSN_1452244015” is DSN name for SQLAnywhere DB.
