We're using IDAA loader V 2.1 to run backups for very huge AOTs. When IDAA loader takes a backup from an IDAA AOT it uses SQL multirow fetch to transfer the data from IDAA into a z/OS sequential file. This may work fine for small AOTs. But in our ...
Today, HLOMAINT utility is not designed to find out what utilities are stuck or dead. To clean up those loader utilities, we run a SELECT * against HLOTB.HLOUSTAT table, review each utility, and run the HLOMAINT job to terminate the utilities one ...
We have an IDAA loader job that disables the table prior to the load to IDAA. Upon successful load of # rows, Loader will end with RC = 0 and enable the table for acceleration again. If the same process is run multiple times and results in "no row...
Enable/Disable replication (InSync) via IDAA HA Loader
If you enable an already loaded table, the following steps are carried out:
○ The data in the accelerator-shadow table is deleted.
○ The accelerator-shadow table is reset to the InitialLoadPending state.
○ Query acceleration is turned off f...
IDAA LOADER job with RC=8 due to just one IDAA load fail
Some of our daily DB2 load Jobs are "DUAL MODE" (DB2 + 4 IDAAs) but we are having issues due to RC=8 when just one IDAA receives error . When the load is sucessful for DB2 and 3 IDAAs but abend for just one IDAA we want to receive at least RC=4 be...
Today, when we have a problem with a Load execution, we can use the BMC ISPF application to terminate the utility or use the DB2 TERM UTILITY command.When using Loader, there is no way to terminate a utility unless using the HLOMAINT Job .So, we n...
missing parm for forceFullReload (or detectChanges="PARTITION") in IDAA loader
According to Stored Procedure Guide V7.1.7 :The forceFullReload attribute is deprecated because detectChanges="PARTITION" withoutpartition list has the same effect as forceFullReload="false", and omitting the detectChangesattribute and a partition...
Rollback changes to both accelerators if failure occurs loading multiple accels in one load statement
We have a situation where it is important to keep the data in synch on both accelerators, so we use one statement to load both accelerators. Real case: The data is loaded from OPERLOG logstream to shadow table every 15 minutes on two IDAA accelera...
Better problem determination when error message is returned to the job submitter
When running a loader job that fails on authorization the submitter of the job does not get a proper message. The message emitted by the IDAA Loader is "HLOU5715E Unknown error during IDAA validation". This is in par with the famous Microsoft Wind...
Use separate HLQs for read-only and updateable product libraries in TCz
TCz should provide an option to allow a customer to specify different HLQs to separate read-only and updateable libraries during product customization. For security and auditing reasons, this separation is required.
