The Replica Location Service (RLS) is a server that provides for the registration and lookup of replica information. Within the RLS, there are two types of services, a catalog service and an index service.
Features New in GT 5.0.1
- None since GT 5.0.0.
Other Supported Features
- Comprehensive C library for replica registration, replica lookup, replica attributes, index queries, and administrative tasks.
- Command line (
globus-rls-cli) tool for client operations on catalogs and indexes.
- Command line (
globus-rls-admin) tool for administrative tasks.
The following problems and limitations are known to exist for RLS at the time of the 5.0.1 release:
- Threading/Libc Problems: set LD_ASSUME_KERNEL=2.2.5 in your environment and see Section 2, “Debian” for more information.
- When a large MySQL database is in use, the RLS server will be unresponsive to user queries for about 30 seconds after startup. The actual duration for which the RLS will be unresponsive depends on a number of factors including the size of the database and the performance of the resource on which the database resides. The estimate of 30 seconds is for a MySQL database with about 20 million entries, on a single CPU (about 2.5 GHz) machine, 1 GB memory and minimal load.
- Threading/Libc Problems: set LD_ASSUME_KERNEL=2.2.5 in your environment and see Platform Notes for more information.
- Bug 3656: ACLs cannot be modified dynamically
- Bug 4141: regexec call in auth.c's auth_getperms
- Bug 4142: globus-rls-admin -s always indicates RLI does not exist

- Bug 6239: Wildcard queries with underscores don't work with SQLite
- Bug 6322: RLS crash on a Sparc/Solaris 10 box (possible duplicate of bug 6356)

- Bug 6662: Unable to install globus_database_sqliteodbc on 64-bits ppc (Suse 10) platform
RLS depends on the following GT components:
RLS depends on the following 3rd party software:
- RDBMS: SQLite*, MySQL, PostgreSQL, or Oracle
- ODBC manager: iODBC, unixODBC
- ODBC driver: SQLite-ODBC*, MyODBC, psqlODBC, or Oracle
* The RLS comes installed with and configured to use these components.
