Hi Folks,
I'd like to get some input/thoughts on the strategy folks are following to bring Clarity from 13.0.x to 14.1.
Here's the scenario of components that need to be touched as identified in the release notes:
- Upgrade Clarity App Servers OS from Redhat 5.10 to 6.4
- Upgrade to Tomcat 7
- Upgrade to JDK 1.7
- Upgrade Oracle DB from 11.2.0.2 to 11.2.0.4
- Upgrade to CABI 3.3 SP2
- Firewalls everywhere
Without getting into dependencies and timelines here are the steps that I'm thinking of following:
| Generic | | |
| Setup Network Connectivity | |
| Upgrade Clarity App Servers | | |
| Current Servers | |
| Replace tomcat with Tomcat 7.0.52 | |
| Replace JDK with JDK 1.7 update 55 or higher and update environment variables. | |
| Remove Clarity customizations | |
| Back up Clarity app server (VM snapshot) | |
| Run Clarity upgrade/install scripts and capture any issues. | |
| Come up with steps to prevent upgrade issues and re-run script until it completes in one run. |
| Export DB Schemas and Import into Oracle 11.2.0.4 |
| Backup application directory and move to new server | |
| New App Servers | | |
| Procure VM's and install RH 6.4 64 Bit | (no upgrade path from RedHat 5.10) | |
| Add JDK 1.7 update 55 or higher and update environment variables. | | |
| Add Apache Tomcat 7.0.52 | |
| Backup properties.xml in each node in the cluster, extract upgraded clarity directory | | |
| Re-configure Application Data sources to point to new Oracle Instance | | |
| Re-integrate cusomizations | | |
| Upgrade CABI to CABI 3.3 SP2 (BOXI 3.1 SP7) | | |
| Replace App Server for BOBJ. | |
| Keep the existing one running while the new one is being built. |
| Setup connectivity to DWH and Transactional DB |
| Install and configure BOBJ (including SSO) |
| Migrate BOBJ content from old server to new one |
| Upgrade DB Server | | |
| Install Oracle 11.2.0.4 | |
| Configure Oracle DB to CA's recommended optimal values | |
| Configure Our Specific Schemas (staging/read-only) | |
