this is merely a documenation post for myself as I always forgot the steps to get this working. as postgres plus advanced server 9.4 was released some days ago we wanted to do another poc for an oracle migration. using edbmtk was clearly the preferred way to do this as it automates most of the tasks. but how did we need to set this up the last time?
as a first step one needs to download the oracle jdbc driver for the java version available on the postgres server.
example:
ojdbc6.jar – for use with java 6
ojdbc7.jar – for use with java 7
put one of these under:
ls -la /etc/alternatives/jre/lib/ext/ total 5264 drwxr-xr-x. 2 root root 4096 Feb 12 12:54 . drwxr-xr-x. 11 root root 4096 Jan 26 18:26 .. -rw-r--r--. 1 root root 10075 Jan 9 02:39 dnsns.jar -rw-r--r--. 1 root root 452904 Jan 9 02:48 gnome-java-bridge.jar -rw-r--r--. 1 root root 558461 Jan 9 02:40 localedata.jar -rw-r--r--. 1 root root 427 Jan 9 02:45 meta-index -rw-r--r--. 1 root root 3698857 Feb 12 12:54 ojdbc7.jar -rw-r--r--. 1 root root 69699 Jan 9 02:46 pulse-java.jar -rw-r--r--. 1 root root 225679 Jan 9 02:41 sunjce_provider.jar -rw-r--r--. 1 root root 259918 Jan 9 02:39 sunpkcs11.jar -rw-r--r--. 1 root root 78194 Jan 9 02:42 zipfs.jar
the next step is to configure the toolkit.properties file:
cat /opt/PostgresPlus/edbmtk/etc/toolkit.properties SRC_DB_URL=jdbc:oracle:thin:@[ORACLE_SERVER]:[LISTENER_PORT]:[DATABASE] SRC_DB_USER=system SRC_DB_PASSWORD=manager TARGET_DB_URL=jdbc:edb://localhost:5432/[POSTGRES_DATABASE] TARGET_DB_USER=postgres TARGET_DB_PASSWORD=postgres
… and then kickoff the migration:
cd /opt/PostgresPlus/edbmtk/bin ./runMTK.sh -fastCopy -logBadSQL -fetchSize 10000 -loaderCount 6 -dropSchema true -useOraCase ORACLE_SCHEMA1,ORACLE_SCHEMA2,...
pretty easy. wait for edbmtk to finish and start fixing the objects that are invalid :)
btw: for migrations to pure community postgres take a look at ora2pg
this is the last very short post of this series:
Create your own Oracle Staging Environment, Part 1: The Staging Server
Create your own Oracle Staging Environment, Part 2: Kickstart File(s) and Profiles
Create your own Oracle Staging Environment, Part 3: Setup the lab environment
Create your own Oracle Staging Environment, Part 4: Staging the GI
at the end of the last post the GI was up and running. from this point onwards it would be easy to use dbca or scripts to setup a RAC database. but we can even automate this. updated script:
save this under /var/www/html/finish_gi_setup.sh on the cobbler vm and fire up the vms. the result is:
crsctl stat res -t
