@zalmanlew we have had groups replicate from Sybase to MSSQL it should not be different than any other vendors

@dikum do you see triggers physically in place on the source tables? Do you see entries in sym_data for capture

dikum

@dikum

@joshahicks There are records in sym_data table on the source DB. Regarding the Triggers, do you mean the records in SYM_TRIGGER table?

joshahicks

@joshahicks

@dikum in sym_data though are there entries for your tables

are changes for your tables being captured

dikum

@dikum

@joshahicks I see there are new records in the table but I don't know how to verify if changes are being captured. Please can you tell me the what to check so I revert? Thanks for your help.

joshahicks

@joshahicks

sym_data has a table_name column and a create_time

you should see new changes coming in here if capture is working

If you see records in here that are new you may want to take the data_id of one of them and query sym_data_event where data_id = ?

Then take the batch_id in sym_data_event that is returned and use that to query sym_outgoing_batch where batch_id = ?

This will tell you if batches are being constructed (as part of the routing process job) and being sent to the target. The status column on the sym_outgoing_batch will tell you if this batch is pending or has been committed on target

dikum

@dikum

@joshahicks I've executed the queries and the status says 'OK' on the sym_outgoing_batch table

joshahicks

@joshahicks

then it should of replicated and committed that change to the target

dikum

@dikum

@joshahicks The issue I'm currently facing is it isn't replicating. The number of rows in my tables are different.

dikum

@dikum

@joshahicks The channel id column is reload, summary has the name of the table. I don't know if this information would be of help.

joshahicks

@joshahicks

thats for initial load but doesnt line up with your queries in sym_data

do you see changes in sym_data for “deafault” channel

dikum

@dikum

@joshahicks If you mean having "default" as a value in the channel_id column, then No, I don't have records for that in the sym_data table.

joshahicks

@joshahicks

default is the main change capture channel unless you setup your own

This would mean you are not capturing changes on the source

if changes are occurring

dikum

@dikum

@joshahicks How can I capture the changes. I'm sorry, these weren't created by me. I just took over the system. So it's a bit confusing at the moment.

joshahicks

@joshahicks

You need to make sure you have valid configuration in sym_trigger, sym_router, and sym_trigger_router.

There is also a professional version that provides a web console for maintenance like this and full support. If that is something you might be interested in we can start a direct chat to discuss those options

dikum

@dikum

@joshahicks Thanks for your time. I'll look into what you've mentioned and get back.

What is the db.driver for MS SQL Server? Would it be com.microsoft.sqlserver?

Zalman Lew

@zalmanlew

I'm trying out the demo, trying to run

../bin/symadmin --engine corp-000 create-sym-tables

I'm getting an error

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class oracle.jdbc.OracleDriver

(corp-000 is using sybase drivers )

joshahicks

@joshahicks

@zalmanlew you need to install the Oracle module

symadmin module install oracle

Zalman Lew

@zalmanlew

@joshahicks thanks, I tried that but got an error

ERROR: Invalid module specified

joshahicks

@joshahicks

@zalmanlew the demo uses H2 by default you may need to remove your engines files and start clean. What database types are you trying to replicate

There is a pro free trial for 30 days that might help you walk through the connection setup if you are having issues creating the engine files on your own

joshahicks

@joshahicks

@zalmanlew also are you running Java 8 or higher

Zalman Lew

@zalmanlew

I managed to download the oracle drivers and got it working. Now I'm just having trouble connecting to my Sybase source.

I'm trying to connect Sybase >> MS SQL

Zalman Lew

@zalmanlew

I'm getting a Connection refused error; I'm able to connect to Sybase via the CLI and run commands

isql -Usa -P{pass} -S{server}

joshahicks

@joshahicks

have you tried a pure JDBC client like Squirrel or DBeaver

Zalman Lew

@zalmanlew

@joshahicks yep, same issue. I think I'm doing something wrong in my Sybase configuration - but no idea what.

Zalman Lew

@zalmanlew

@joshahicks I managed to get connected using DBeaver on my Mac (through an SSH tunnel). However I'm still getting the connection refused error when running the following command

../bin/symadmin --engine corp-000 create-sym-tables

this is the configuration of corp-000 (yes, the actual database name is databasename)

db.url=jdbc:sybase:Tds:localhost:5000/databasename

I was able to successfully connect using jConnect as well as jTDS from DBeaver

Zalman Lew

@zalmanlew

Worth noting that SymmetricDS is installed and being run locally (on the machine with the Sybase install)

Zalman Lew

@zalmanlew

@joshahicks after hours of messing around, I managed to get it working by changing the DB to listen on 127.0.1.1 instead of localhost (note the 1 instead of the common 0).

I'm facing an issue now when trying to create-sym-tables - it's giving an error

java.sql.SQLException: JZ0SB: Parameter index out of range: 1.

Any ideas?

Zalman Lew

@zalmanlew

Also, what is the official db.driver for SQL Server? Would it be com.microsoft.sqlserver?

joshahicks

@joshahicks

@zalmanlew we use to ship the JTDS driver but have swithched to the MSSQL one with the latest releases finding it faster and more stable

Are you using SQL Anywhere for the other issues above by the way

Hola alguien sabe por que no puedo escoger master o node

joshahicks

@joshahicks

@susanap23640384_twitter ¿Te refieres a la consola web? Cambiamos la redacción. "Configurar nuevo .." = "Maestro" y "Unirse a existente..." = "Nodo".

@susanap23640384_twitter

Al darle clic en Open Web Console la siguiente pantalla no me deja escoger master , o nodo , dice que existe un error inesperado

joshahicks

@joshahicks

Mire logs/wrapper.log y vea qué error está teniendo al iniciarse. El siguiente lugar para verificar es logs/symmetric.log.
