Oracle GoldenGate for Sybase provides real-time, log-based change data capture and allows users to replicate data from supported Sybase ASE databases, to Sybase ASE or other major databases including Oracle Database, HP NonStop, IBM DB2, SQL Server, MySQL etc.
Many companies use Oracle GoldenGate for Sybase to perform zero-downtime data migrations, in addition to enabling high availability, and real-time data integration for transactional and analytical systems.
Though documented in the Oracle GoldenGate for Sybase Installation Guide, there are still many questions on how to install Oracle GoldenGate for Sybase. In this blog, I want to walk you through the setup steps and discuss the tip and tricks in the installation process.
You can find below the steps for installing Oracle GoldenGate for Sybase on LINUX:
Step 1: Download Oracle GoldenGate for SybaseYou can download Oracle GoldenGate from Oracle eDelivery or support.oracle.com. This example downloads the 11.2.1.0.1 for Sybase 15.5 from Oracle eDelivery. The following is a screenshot of the eDelivery download page:
Step 2: Unzip the Oracle GoldenGate zip File.Unzip the downloaded file with the following commands: unzip V32422-01.zip tar xvf ggs_Linux_x86_sybase15_5_32bit.tar Check the shared library path: env |grep LD_LIBRARY_PATH LD_LIBRARY_PATH=/home/sybase/ASE-15_0/lib:/home/sybase/DataAccess/ODBC/lib: /home/sybase/OCS-15_0/lib:/home/sybase/OCS-15_0/lib3p:/home/sybase/ASE-15_0/lib: /home/sybase/DataAccess/ODBC/lib:/home/sybase/OCS-15_0/lib: /home/sybase/OCS-15_0/lib3p: Add the OGG installation path to the path (PATH) and shared library path (LD_LIBRARY_PATH) environment variables: export PATH=/home/ogg_for_sybase:$PATH export LD_LIBRARY_PATH=/home/ogg_for_sybase:$LD_LIBRARY_PATH Step 3: Create Oracle GoldenGateRun the ggsci command in the folder where Oracle GoldenGate files are unzipped: ./ggsci GGSCI> create subdirs Parameter files /home/ogg_for_sybase/dirprm: already exists Report files /home/ogg_for_sybase/dirrpt: created Checkpoint files /home/ogg_for_sybase/dirchk: created Process status files /home/ogg_for_sybase/dirpcs: created SQL script files /home/ogg_for_sybase/dirsql: created Database definitions files /home/ogg_for_sybase/dirdef: created Extract data files /home/ogg_for_sybase/dirdat: created Temporary files /home/ogg_for_sybase/dirtmp: created Stdout files /home/ogg_for_sybase/dirout: created GGSCI>Exit Step 4: Create Database User in Sybase for Replication.In the Sybase database, create a database user for Oracle GoldenGate, and grant the sa_role and the replication_role to that user: Isql –Usa –P –SASE1 1> sp_addlogin ogguser,ogguser 2> go Password correctly set. Account unlocked. New login created. (return status = 0) 1> sp_adduser ogguser 2> go New user added. (return status = 0) 1> sp_role 'grant', replication_role, ogguser 2> go Authorization updated. (return status = 0) 1> sp_role 'grant', sa_role, ogguser 2> go Authorization updated. (return status = 0)Step 5: Start GGSCIexport DSQUERY=ASE1 >./ggsci GGSCI> edit param mgr port 15002 GGSCI> start mgr GGSCI> info mgr Manager is running (IP port syslab.us.oracle.com.15002)
With these few steps, you then complete the steps for installing Oracle GoldenGate for Sybase. As a reminder, you can refer to Oracle GoldenGate Sybase Installation and Setup Guide for more information. In the next blog, I will discuss how to setup Oracle GoldenGate to perform a one-way replication from Sybase ASE database to Oracle Database. Please let me know if you have any questions or comments on the tips I provided above. |
