As our current R environment still uses R-2.1, the latest ROracle-0.5.8 can not be installed (minimal requirement is 2.3+). Instead, we tried to install ROracle-0.5.5.

varchar(byte) vs. varchar(char)
In oracle, varchar2 is widely used to hold variable length string. For varchar data type, there are two minor variants: varchar(byte) and varchar(char).

ensembl+DAS deployment
I have migrated “ensembl + DAS” from Marie’s linux workstation to Kampen and Genesis successfully. Marie has helped me to do everything from scratch (including hacks on ensembl web codes), so that we can track on the changes made. Below is the draft I sent to Ramneek/Neal/Kevin/Tim for review. I also proposed having all these discussed in CMAB meeting when Ramneek is back.
moving Marie’s DAS code to kampen
Marie has developed as few DAS service for Ensembl web. Previously the DAS ran on Marie’s own machine and the support team is requried to move this to production. Before I move it, it will be set up on kampen as a testing environment.
