    Oracle Cluster 3.3 with LDAP agent

    user5307432
      Dear Experts


      I am trying to install Sun cluster 3.3 u1 with LDAP 6.3 but I failed and Now i will try for LDAP 7.0 .


      Anyone has experiance on this and why is failing?

      I heard that LDAP can be ACTIVE-ACTIVE without cluster ? Is it correct ?

      Thanks
      Ehab

          Hi Ehab,
          if you don't have any special requirement in terms of versions, instead of remaining with DS 6.3 I strongly suggest you to move to a later version ODSEE 11gR1 Patch Set 1 (11.1.1.5.0) with the latest patches (11.1.1.5.1), because of the large number of bugs fixed since then; or even explore the new approach of OUD 11.1.1.5.0

          In terms of application deployment, regardless the ODSEE/OUD version you'll choose, I would strongly recommend you to avoid the old approach of O.S. clustering; application level clustering (Multi-Master replication, available for more than 10 years!) is much more reliable.

          HTH,

              Please note the LDAP which i am installing for Messaging Queue application , I am not sure if ODSEE 11gR1 is supported.

                    Can I create GDS script for startup and shutdown and include them in sun cluster?

                    Thanks

                      IMHO you should not use a "cluster stuff" (the Generic Data Source) to star a service that is host-based. For this reason, I would simply go for a SMF service.

                      The reason is in that case you'll keep completely separated the administration of your cluster stuff (scrgadm) from the administration of your local services (svcadm).

                      Last, but not least... if you have to boot the node outside from the cluster (boot -x), you can always keep starting the LDAP without any problem, instead of relaying on the cluster framework.

                        Hi

                        How to use SMF service to start and stop LDAP ?

                        can you please elaborate more.

                        Thanks

                          Please refer to the following documentation:

                          Sun Directory Server Enterprise Edition 7.0 Administration Guide:
                          http://docs.oracle.com/cd/E19424-01/820-4809/fxxpi/index.html

                          and please look at step 3 (optional):

                          "if you installed Directory Server using the native packages and your operating system provides a service management solution, you can enable the server to be managed as a service"

                          In your case, on Solaris 10:

                          # dsadm enable-service --type SMF instance-path
