Configuring Replication with high-availability RAC clusters.
David BreinholtKerry Howell
Outline
• Our internal requirements• The challenges of 99.9% uptime• Our architecture• How we setup SharePlex• How we configured SharePlex• CRS Integration• Useful commands• Final Thoughts
Service Level Agreement
• Must maintain 99.9% availability• Maximum allowed outage of 43.8 minutes/month• Not allowed to combine monthly allocations• Financial penalties will be paid for overages• Zero scheduled downtime allowed
This product is Highly visible to Executive team, so it is in our best interest to proactively meet the requirements of the Service Level Agreement.
• Upgrade Oracle – upgrade inactive silo, failover• Patch Oracle – patch inactive silo, failover• Quarterly software releases – inactive silo, failover• Hardware failure/updates - failover to inactive silo• Software failure – failover to inactive silo• User error – use flashback table/database• Disaster recovery – storage replication to NJ site• OS Patches/upgrades
… all with near zero downtime!

Research
• RAC– Upgrading with no downtime is questionable– Does not facilitate our quarterly releases methodology
• Data Guard– Upgrading with no downtime is questionable– Target site is down (or read-only) when propagating changes– Active data guard is additional cost– Switchover takes minutes+ to complete
• Golden Gate– Ability to compare/repair data is an add-on (expensive)– Could not justify the cost of the product missing functionality
• SharePlex– Seemed to satisfy all our requirements
Decision
During our discovery effort it was determined that SharePlex was the best solution for the following reasons:
• Intuitive setup and configuration• Cost effective compared to other solutions• Detects when table get out of sync• Includes the ability to compare and repair tables• Allows bi-directional replication
Setup
In the source environment:
Create the required tablespaces
CREATE TABLESPACE SPLEXDAT DATAFILE SIZE 50M AUTOEXTEND ON NEXT 100M MAXSIZE 5G LOGGING EXTENT MANAGEMENT LOCAL AUTOALLOCATE BLOCKSIZE 8K SEGMENT SPACE MANAGEMENT AUTO FLASHBACK ON;
CREATE TABLESPACE SPLEXIDX DATAFILE SIZE 50M AUTOEXTEND ON NEXT 100M MAXSIZE 5G LOGGING EXTENT MANAGEMENT LOCAL AUTOALLOCATE BLOCKSIZE 8K SEGMENT SPACE MANAGEMENT AUTO FLASHBACK ON;
Setup - Continued
Obtain new IP addresses in the same network as the SCAN interface IP addresses (for each cluster):
Utah:Silo A: 192.168.1.10Silo B: 192.168.1.20
New Jersey:Silo A: 192.168.2.10Silo B: 192.168.2.20
Setup - Continued
Obtain DNS entries for the new IP addresses:
Utah:192.168.1.10 - inst_a-splex-vip.xactware.com192.168.1.20 - inst_b-splex-vip.xactware.com
New Jersey:192.168.2.10 - njinst_a-splex-vip.xactware.com192.168.2.20 - njinst_b-splex-vip.xactware.com

Create the CRS VIP to allow SharePlex to failover between RAC nodes:
Utah Silo A (only on one of the nodes)as root:${CRS_HOME}/bin/appvipcfg create -network=1 -ip=192.168.1.10-vipname=shareplex.vip -user=oracle -group=dba
as oracle:crsctl start resource shareplex.vip
Utah Silo B (only on one of the nodes):as root:${CRS_HOME}/bin/appvipcfg create -network=1 -ip=192.168.1.20-vipname=shareplex.vip -user=oracle -group=dba
as oracle:crsctl start resource shareplex.vip

Configuration
Create the Silo A SharePlex configuration file:
cd /u02/app/quest/vardir/configvi schema_name_all
datasource:o.inst_a_SP
#source tables target tables routing mapexpand schema_name.% schema_name.% [email protected]_b_SP
Note: This will replicate the schema_name schema from silo a to silo b.
Configuration - Continued
Create the Silo B SharePlex configuration file:
cd /u02/app/quest/vardir/configvi schema_name_all
datasource:o.inst_b_SP
#source tables target tables routing mapexpand schema_name.% schema_name.% [email protected]_a_SP
Note: This will replicate the schema_name schema from silo b to silo a.

Stop Target Post:On silo B ONLY (on the host with SP VIP):sp_ctrlstop post
Activate Config:On the Silo A (on the host with the SP VIP):sp_ctrlactivate config schema_name_all
Note: the “activate config” begins tracking changes to the schema schema_name.

The next step is to duplicate the Silo A database to the Silo B database. It does not matter which method you use to get the source copied to the target (impdp, rman, etc.) as long as you have a consistent SCN to pass to SharePlex.
When using rman make sure to record the following from the duplication log file:

If this Process hangs it is likely related to no activity on the source. Log into the source database and create at least one transaction, then force a log switch.
NOTE: This will not apply transactions yet...

Cleanup Target Tables:Run the cleanup.sql script to truncate all of the SharePlex internal tables.
Only run this on Silo B:
cd /u02/app/quest/sp/bin
sqlplus splex/<pass>@[email protected]
Setup - Continued
Modify Triggers: On Silo B (or both silos if you are bi-directional), disable triggers on the replicated tables, or run the sp_add_trigger.sql utility script so that the triggers ignore the SharePlex user. This will prevent circular replication.
cd /u02/app/quest/sp/util
sqlplus “/as sysdba”@sp_add_trigger.sql
Enter SharePlex username --> splex
Verify all the triggers in the replicated schema have the following:
WHEN (USER != 'SPLEX' )
Setup - Continued
Before moving on with the next steps, make sure that there are no replicated tables with constraints that are “on delete cascade”. This will cause issues with replication and must be disabled.
ALTER TABLE table_name ADD CONSTRAINT constraint_name FOREIGN KEY (column) REFERENCES table_name (column_name) ON DELETE CASCADE ENABLE VALIDATE
NOTE: If you are planning on bi-directional replication, neither silo can have this set.
Setup - Continued
Sequences:If you are planning on active-active in your configuration then you have 2 options for sequences.
(1) - Alter one cluster to odd and the other to even and increment by 2. Example: select sequence.nextval from dual; (until odd or even), then alter sequence sequence_name increment by 2;
(2) - Use sequence ranges for each silo in the cluster.
The recommended method is to use odd/even to avoid conflicts.
Determine the best method for your setup and make the sequence changes before moving on with the next step.

NOTE: Silo B will now post the changes from the beginning of the duplicate database until current. May take some time to catch up.

Final Thoughts
We are pleased with the overall value of the SharePlex product. The cost is reasonable for the functionality it provides, and we are satisfied with the stability and performance as well. If you combine that with the ease of setup and administration it becomes clear that SharePlex is a good fit for Xactware.
